[Guide] NVMe-boot w/o modding the BIOS (Clover-EFI method)

Worked great…
Thank you for you and your team…

Hello, good afternoon forum people.

Sorry for my English.

I’m going to tell you about my problem, I can’t start clover on my Dell Optiplex 320, Pentium 4 3.0 ghz socket 775, 2 gb ram ddr2, NVME Samsung 256 gb, M.2, model PM99, 2230 PCIE.

I tried several versions of Clover and the same thing happens with all of them.

I changed to several resolutions in the config.plist file and there was no solution.

The pendrive created with clover works perfectly on other PCs.

I leave an image of the problem.

I hope someone can help me.

Thank you very much!

I want to test clover, and i have:

  1. biosLegacy (without uefi)
  2. sata ssd (evo 860 1tb samsung), mbr, partition one (whole drive), ntfs.
  3. win11 booting via bootMgr (bcd).

I would like to test it like this:

  1. i do not want to install it on usb or any external drive.
  2. i want to put it on some location on c: (like c:\cloverV2\efi)
  3. i want to add it as bootMgr option via bcdedit (a link to clover boot[sect or loader] should be added) (to have two options: 1. “windows 11” (present on drive, working without clover), 2. “clover”.

I want to do this just for testing purposes. win11 mbr bootmgr is already booting fine. i want to test if clover can be run like this, so if there is in future some uefi boot option, that it can be booted.
by looking at clover bootSectors, bootLoaders there is not one for ntfs (only fat, exFat). so there is a possibility that clover can not access its files on volume ntfs.

Attempting to boot from an nvme on an asus m51bc computer. I haven’t been able to successfully mod the bios.

I have tried the BDU tool to create a Clover bootable usb. I have also tried to download an existing clover usb image and apply it to the usb drive with Rufus.

Either way my clover is stuck at scanning entries.

I have tried searching the forum and found two others who had posted about this in the past but no solution was found.

EDIT:
Updating how I solved issue - never got Clover working but I used the instructions from this thread [Guide] NVMe-boot for systems with legacy BIOS and UEFI board (DUET-REFIND) to install DUET and REFIND to bootable usb. Easily booting to the nvme drive this way. Bought a low-profile usb key and have it out of the way in the back of the pc for booting.

was also struggling with the Scan entries… screen hangs there forever…
and debug log logged as

with many random try i got blessed…
I added EmuVariableUefi.efi along with NvmExpressDxe.efi… in EFI\CLOVER\drivers\UEFI … it worked for me.

Hello.
After upgrading Windows 11 from 23H2 to 24H2, I can no longer boot Windows from Clover.
When I select Boot Microsoft EFI Boot from EFI from the Clover menu, Windows does not start and the same Clover menu is displayed again.
Clover is installed on an SSD connected to SATA. However, Windows can be booted from Clover connected via USB.
What could be the cause?

pc: lenovo 47461NJ Made in 2012
cpu: intel Core™ i5-2320 P67 Express
Windows was upgraded with rufus4.6

BootDiskUtility: v2.1.2022 rev.030b
clover: Rel.5160

Since your ASUS M51BC mainboard has an AMI UEFI BIOS, it will be possible to boot directly off the NVMe SSD after having inserted the related NVMe BIOS module into the BIOS by following >this< Guide.

Why haven’t you posted a “BIOS Modding Request” into the related Forum Category?

@AIBow
The fact, that you were able to solve your problem by connecting the Clover EFI Bootloader via USB port (instead of a SATA port), indicates, that there has been something changed regarding the Windows Disk Management.
What sort of SSD (manufacturer and model) did you use for the Clover connection and which are the SATA settings within the mainboard BIOS?

Hello,
I will answer as follows.

SSD: Silicon Power A55 series SP128GBSS3A55S25
SATA option: AHCI mode

@AIBow
Thanks for your quick reply.
I suspect, that your SATA SSD is not bootable (needs a boot sector).
Why have you changed your boot medium? The USB connection obviously worked.
According to the start post of this thread it is strictly recommended to use an USB flash drive or an SD-card as bootable device.

Thank you for your reply.
However, when using Windows23H2, why was it possible to boot from the SSD without any problems?
The boot media is SSD from the beginning.

@AIBow
Are you sure, that Win11 v24H2 officially supports your old system at all?
There are meanwhile a lot of restrictions regarding the compatibility.
So I recommend to be happy as long you are able to use the latest Windows OS at all.
