[Guide] NVMe-boot without modding your UEFI/BIOS (Clover-EFI bootloader method)

For sure you are wrong.
Clover can boot to an OS installed on a EXT4 partition (Linux) on a GPT NVMe drive.
This is what I did when I installed both Linux Mint (LMDE 4) and Kali Linux on my NVMe drive (which is linked to my MB through a PCIe adaptor).
I have also installed Windows 10 and Windows 11 on the NVMe SSD. Everything works.
See my post #817.

Since you have created a Clover key which - apparently - works, have you tried to insert an Ubuntu USB installation drive and see if Clover can recognize it ?
Since I have recently done successfully what you are trying to do, I might be able to guide you further. Just advise…

Hello all,

I have here an old Lenovo T400 with a ThinkMods NVME adapter.
This adapter has an built-in SD card with 2 GB in addition to the installed Sabrent SSD.
The purpose of this SD card is to boot Clover from there (so without USB stick) and then use the SSD for various operating systems (eg Windows 10).
On this SD card Clover is installed with all drivers - but unfortunately I do not manage so far to boot Clover via this constellation (black screen / blinking cursor).

Therefore I have now prepared a USB stick (on the T400 via a former Win7 installation) via BDU and can get into the Clover menu with it (via boot7 as described in post #815).
Unfortunately Clover only shows the 2 GB SD card as bootable medium and not the connected SSD (GPT and NTFS formatted) or any other USB-Stick.

The plan now is:
1. exit Clover (bottom right menu)
2. boot maintenance manager
3. boot from file
4. choose Rufus prepared Win10 image USB stick
5. choose EFI/BOOT/boot64x.efi
6. Install Win10 on NVME-SSD

Unfortunately something still seems to be fundamentally wrong.
When I exit Clover and try to go into the Boot Maintenance Manager, the Boot Manager, the Device Manager or just continue the boot process, Clover crashes with an X64 exception (black screen / red text).

How can I prevent this, or what is wrong?

Greetings Franzl

I have recently succeeded in installing Windows 10 and Windows 11 on my non-bootable NVMe SSD, so I hope to be able to help you based on my experience. See my post #817.

I am not sure what you mean by “Clover does not see the ……. drive”.
From my experience, Clover does not show drives, but OS installations. So, if you do not have any OS installed on your SSD at present, as I presume, you should not bother about this.

So you have gone through:
Exit Clover → Boot Maintenance Manager → Boot from file → Windows 10 USB drive → <efi> → <boot> → bootx64.efi
This is exactly what I did to install Windows. You’re on the right track !

By the way, after you created your Clover key, did you copy the ‘EFI/CLOVER/drivers-Off/drivers64UFI/NvmExpressDxe-64.efi’ driver to:
‘EFI/CLOVER/drivers64’ and to:
‘EFI/CLOVER/drivers64UEFI’ ?
This is essential !

I see 2 possible reasons why Clover then crashes.
1. Problem with the Clover key
2. Problem with the Windows Installation USB drive.

You may like to rule out #2 first.
Which options did you use in Rufus when you created your Windows Installation USB drive ?
For me, I selected: GPT – UEFI (non CSM) – FAT 32.
With any other options, the USB drive may be successfully created, but the installation with Clover will fail.

If you think that your Windows Installation USB drive is fine, then you may like to look at reason #1 (Problem with the Clover key).

To create my Clover key, I used:
- BootDisk Utility v2.1.2018.023b
- Clover version 4961 (CloverISO-4961.tar.lzma)
With any other combination of BDU or Clover versions, I failed : either I was unsuccessful in creating a Clover key, or I managed to create a Clover key, but it did not work (I did not succeed in installing an OS then).
In particular, the latest version of BDU (v.2.1.2020.028) never worked for me.
And I never succeeded in creating a working Clover key without BDU !

See if that helps, and pls report any progress.

Problem solved!

Just re-recorded the SD card via BDU with Clover and replaced my config.plist and copied the NVMe drivers as generally described in the associated folders and voila! EVERYTHING WORKS!

Boot via ThinkMods adapter SD card to the Sabrent 512 MB SSD installed in the adapter with Win10/Win11 works flawlessly.
Problem solved - I am happy and can recommend the adapter card without any restrictions.
Only drawback is the somewhat critical physical fit - I had to take the file to hand and file off the plastic a bit.

The problem with the Clover crash as described above still exists, but is no longer relevant, since I have found another way.

Many thanks to all!

Hi sibliss,

how can I hide entries in boot selection when they have no volume name?

If your volumes are not named you could either use diskpart to add a name easy option or if i recall correctly you could retrieve the volumes guid from diskpart and set <guid>guid of volume</guid> instead of string in the array. (note make sure it’s the volumes guid not the disks guid). i think think i’ve read somewhere that that works but i haven’t tried it myself.

Edit by Fernando: Unneeded fully quoted post removed (to save space)

Finally I made it!

It takes me some hours but after all I hide all unnecessary entries and setup the autoboot without Clover GUI - perfect for me!

Thank you very much!

Full text is below
1. What does “boot from file” mean(I did it thru clover shell but that’s all I know)?
2. Where do I get BootDisk Utility v2.1.2018.023b?
3. What the heck is a boot manager? Is it something windows made?
4. Where is the boot section of the config.plist file?
5. Whats the formating required to add the UUID into the config.plist file?
6. Is there a clover manual ( I just now thought of that)?

I can install onto the NVMe thru Clover shell and without clover shell. Instalation media is shown in Clover as well. I used an older CloverISO but not an older BDU.

Full text of my post:

SO yeah, I have a lot of questions and I’ll answer some questions others asked(thank you for your support). I think most importantly is what does “boot from file” mean? They only way I was able to follow #613 directions was to enter the shell of Clover. When I exit clover I get options like, boot manager, boot from file, and something else, but they all go to a black screen and freezes.

I was able to get the black screen with red text like #822. However, when I tried to follow #823 directions, I could not find anywhere on the internet BootDisk Utility v2.1.2018.023b. I belive that I did use Clover 4961 or something older than the presant(I forget which post told me to do that) Moreover, #820 says that I have to manually enter the UUID of the volume, (not actual drive) of my NVMe drive into the config.plist file boot section. I cannot find this boot section and, lol, I wouldn’t know how to enter the values in it even if I did know. Sorry @sibliss T.T

Anyways, to answer some questions, I can successfully install ubuntu by loading the bootx64.efi file from clover shell. Actually, I can install it without it as well. But, of course, does not show up in Clover. I don’t even think it shows up in the shell. it just says fs0:, Blk0:, Blk2:. both the blk entries say file not found when I type “dir”. I have it put in my PCIe x16 slot. (is that what a graphics card usually goes into, i think that’s what it’s called)

@Morbius Clover does pick up my installation media within the GUI.

Someone else asked something I think: I did not install windows thru clover but it shows my windows install (that’s not on the NVMe, just a HDD).

lets start with the easy ones…
2. you can find the link to the BDU in the what to download section of post #1 at the very start of this thread.
6. i am not aware of any manuals that would be nice, the best i can do is point you to the wiki i found linked in my post #493
5. the config.plist is all xml i briefly touched on how all xml parameters should look in post #826 (note the opening and closing tags on the line)
4. open the config.plist file with a text editor and look for this line that denotes the start of the boot section “<key>Boot</key>”
1. i have no idea what that is or why that would be required… at that point you should just be able to use your boot media i think
3. i’m going to assume thats just a reference to the built in utility for managing boot devices in clover or windows (i’m not sure what we are referencing here)

here is an example of the default boot key in the boot section of the config.plist yours should look similar

anything else let me know,

I friggin did it!

Thanks a lot for your reply sibliss but @Morbius said that I needed BDU 2018 version not the 2020 version. crazy, right?
I also found out that i did not use cloverISO v4961.
I finally found the BDU 2018 version on some random vietnamese website. so, im going to try clover ISO v4961 However it did not work. I had to use BDU 2018 version 024b not 023b. This worked even on boot6 and i did not have to install ubuntu(as i previous did before) it just worked.
Moreover, @sibliss , I cannot add the guid into the config.plist as your instruction. i have to write it as a string, otherwise it errors out and skips it.
<string> guid of volume </string> you said to do guid

Even so, clover did not pick up the dirve, even when i went into shell and did map -r
I’m going to write step by step what i did. Then post on here. Everything I have learned. Also i’ll post the files i got so that others don’t have to look for them as i did.

Holy crap, this project gave me a few white hairs. However, I, of course, did nothing special. The real heros are the Dev team. Thanks again. Here’s some coffee.[orange]

ah sorry i should have stated the <guid> tag is used in the other part of the file in relation to hiding drives thing not in the default boot section if i recall correctly, that was just a reference example to xml structure.
moving on i wonder what the 2020 bdu lacks that made it not work for you?

alas i am pleased to hear you got it working.

ooo, one more question @sibliss , um, how do i make Clover boot into my OS automatically. When I set the timout to 0 it still takes me into Clover, same when I set fast to true Not sure what im not getting here.

Edit: I’m going to reinstall ubuntu through clover to see if that’s the issue.

Re-edit: I did it. I could not boot by writing out the UUID, nor the directive (nvmeOn1p1), nor LastBootedVolume, nor the full path (HD(1,GPT, uuid, some hex number , some hex nubmer) but i looked at what my drive was called when i booted up clover and it was called EFI??? don’t know why it was called that but it’s calld EFI so i put that in DefaultVolume and volia

I feel like a million bucks. I’d buy both you guys some coffee if i could. ^.^

I read in your post #830 that you did it. Congratulations !

Nevertheless, I will answer the important question you asked in your post #828 as it could be useful to others.

The answer is : you get it … from me !
I have attached to this post the 2 files I used for successfully creating a Clover key that works :
• BDUtility.exe (v2.1.2018.023b)
• CloverISO-4961.tar.lzma

(compressed in the CLOVER.zip file attachment. You need to decompress it)

Instructions I followed to create a Clover key in Windows

Make sure the above 2 files are in the same folder.
Start BDUtility.exe.
Click Options → Configuration.
Under Clover Bootloader Source:
. Local and CloverISO-4961.tar.lzma should be selected and Rev: should indicate 4961.
Under Format Options / Boot records:
. Clover should be selected. The Format option should be FAT32 or FAT32-LBA.
Under Multi Partitioning:
. Boot Partition should be selected with a size of 200 MB.
Click OK.
Insert a USB drive. It should appear in Destination Disk.
Click Format, and then OK. The Clover key creation process starts.
Wait until the ‘All Done’ message is displayed (it can take a few minutes…).
The Clover key has been created, and you can close BDUtility.
But one last action remains to be done on the newly created Clover key before you can use it to install an OS on an NVMe SSD:
Copy the ‘EFI/CLOVER/drivers-Off/drivers64UFI/NvmExpressDxe-64.efi’ driver to:
• 'EFI/CLOVER/drivers64’
and to:
• ‘EFI/CLOVER/drivers64UEFI’
Once this is done, you can start to use the Clover key.

By the way, which CloverISO version did you use ?

In your post, you also wrote :

I am a little puzzled here.
Did you actually install Ubuntu on your NVMe SSD or not ?
And, if you did, can you boot on it through the Clover key you made ?

Hi all! I followed the instructions and was able to successfully install Ubuntu on my NVMe drive, but it won’t boot. Clover comes up ok, but it doesn’t show any options for booting into the OS. When I press F3, it shows a button that kicks me back into Clover. When I go into the Shell, it shows the 3 NVMe partitions that Ubuntu created during the install, but doesn’t show anything in them. I tried modifying the config.plist to directly call out each of the partitions, but it still doesn’t boot. I’m sure I must have something in the config.plist file wrong. (Maybe lots of somethings) This is my first time doing this, so it is entirely possible that I missed a step or installed Ubuntu incorrectly, but the installation proceeds fine.

I don’t think the problem is with the NVMe drivers, since I can see the NVMe drive when I map from the Clover shell, but I could be wrong.

I attached the .plist file as a .txt so you could look at it. I figured it was easier that way.

Welcome to the forum !

I notice that, coincidentally, you have the same CPU than me (mine is from year 2009 !). As you can see in my post #817, I succeeded in installing 4 OSs with Clover in my NVMe SSD, and boot to each of them. So I hope I might be able to help you.

I won’t be able to tell you much what might be wrong from your .plist file. I am far from understanding all the info/data from this file. Perhaps someone else will…

However, what I can do is to explain you with as many details as you wish what I did to create a Clover key that works, and then install OSs which you can later boot to from it. It is up to you if you wish to follow my guidelines.

First, I notice that you used Clover v.5145. This version of Clover never worked for me. The only version that worked for me is v.4961. I created my Clover key with BootDisk Utility v2.1.2018.023b (and not with the latest BDUtility).

I have detailed the instructions I followed to create my Clover key in post #833.
I have also attached a copy of the files I used to that post (BDUtility.exe (v2.1.2018.023b) and CloverISO-4961.tar.lzma).

Could you indicate which version of Ubuntu you tried to install ?
If you could provide a link to the page from where you took the image file of the Ubuntu you tried to install, I could create an installation disk and try to install Ubuntu (the same one you’re trying to install) on my system, and let you know the result.

@Morbius Thanks for the welcome! I will try the previous version of Clover and BDU.

I installed Ubuntu Server 20.04 from ubuntu.com/download/server. I selected Option 2, then hit the download button. Once I had the ISO, I made a bootable USB using Rufus. (Sorry for no link. I don’t have enough posts yet…)

I’m so sorry @Morbius. i thought i posted this earlier.

Well, i did use clover v4961 but it did not work with the BDU v2.1.2018.023b. I had to use DBU v2.1.2018.024b. This version the local directory was not greyed out. I did install ubuntu, but i could install it with any version of clover.

Since I had installed it already on previous attemps, when I tried clover v4961 it immedially picked up the drive, or rather the installed ubuntu OS. I was even able to have it autoboot since clover named the drive ‘EFI’.

I will try to post the entire process i used to do it, everything i learned. what worked for me and what didn’t, whenever I have time.

How to install Windows on SSD Samsung 980 using connecting via adapter ExpressCard to NVMe. I have used Clover to boot by copying the ‘EFI/CLOVER/drivers-Off/drivers64UFI/NvmExpressDxe-64.efi’ driver to:
• 'EFI/CLOVER/drivers64’
and to:
• ‘EFI/CLOVER/drivers64UEFI’
but when attempting to start to install Windows from under CLOVER from a USB drive the installation can’t continue, I suppose, because no integrating NVMe SSD driver from Samsung into Windows setup image, as for Samsung NVMe SSD controller represent a special class of devices alike Intel RSTe RAID controller.
I have cloned Windows on this Samsung, but when booting via Clover appears BSOD -disk is inaccessible. Using Windows TO GO on this disk as an external USB SSD was enough acceptable.
In additional, if by extracting .sys, .inf and .cat files from driver installation Samsung_NVM_Express_Driver_3.3 .exe file it can be fixed? But again is this driver suitable for such a purpose and in what way to extract .sys, .inf, and .cat files from the driver installation .exe file? I have tried “FlashBoot Pro” for integration, but without success.
I’d be grateful for the advice or assitance in this matter.

I am really puzzled to read that you could not use BDU v2.1.2018.023b because v.4961 was greyed out !
I am just wondering which version of BDU v2.1.2018.023b you used…
Probably not the one I attached in my post #833 since you first mentioned you had a problem with this BDU version in your post #830, … that is earlier !

I can assure you, and anyone else here, that when I use the 2 files I attached in my post #833 (which must be in the same folder), the local directory is not greyed out (see attached image), and I can create a Clover key that works !

Screenshot 2022-03-23 191650.jpg

Anyway, since you mentioned that it finally worked for you, you solved your problem !
And I am glad to read that, at the end, CloverISO v.4961 which I had mentioned earlier worked for you as well ! Congratulations !

I have good news for you !

I succeeded in installing Ubuntu Server 20.04.4 through Clover on my NVMe SSD, and I can boot from it through the Clover key !

These are the steps I followed :

1. I created a bootable USB drive from the ubuntu-20.04.4-live-server-amd64.iso from the link you mentioned. For this, I used the Balena Etcher flash utility, and not Rufus. I usually use Etcher for flashing USB drives with images of Linux installation drives, and I use Rufus with MS Windows installation drives.

2. I inserted the Clover drive in my system and booted from it. As soon as Clover starts to load, I then inserted the Ubuntu Server installation drive I created in Step 1.
[Edit : I think that you can also insert the Ubuntu Server installation drive once the Clover bootloader menu has been displayed. Then, you will see a new icon pop up in the screen. This is the icon you need to select to start the installation process in Step 3]

3. In the Clover bootloader menu, I selected the ‘Boot UEFI optical from CDROM’ icon with the left/right arrow keys, and then pressed ENTER. Doing this made the Ubuntu Server installation process start.

4. Once the Ubuntu Server installation process was completed, I removed the Ubuntu Server installation key, and I restarted the system.

5. The Clover bootloader menu now shows an new icon/entry for the Ubuntu Server. I selected this entry, to start the Ubuntu Server. Once it has completed to load, it shows a command line.


During the Ubuntu Server installation process in Step 3, I choose a custom installation for the storage selection, since I already have Kali Linux and Windows 11 installed on my NVMe SSD. But, for you, you may like to select an installation on the entire disk if you don’t intend to install any other OS. Well, it’s your choice.

Good luck ! And please let us know the result !
