Cannot completely install Windows 7 on Acer Predator Helios 300, G3-571 Kaby Lake

I’ve been trying to install 7 x64 on my laptop for the past 2 days with no avail. The laptop has a 7700HQ with HD 630. I was able to start the installer from a USB stick by using UEFISeven, but after the installer reboots for the first time it no longer boots to continue. I made sure that the EFI being booted on the drive is uefiseven renamed to bootmgfw.efi, with the original bootmgfw.efi being renamed to bootmgfw.original.efi. I have provided a log from the verbose section, which shows that it unlocks the region fine. I’ve also tried the method of disabling vga.sys and vgapnp.sys and modifying the registry (http://reboot.pro/topic/21108-install-wi…l-gop-hardware/), but it did not help either.

If anybody can provide some help, that would be appreciated. I can provide more info where needed.

better try RUFUS + WIN7 ISO ,.,.here create USB
and think you need CSM boot ,…and no secure boot ? ,.,.and full remove disk “diskpart -clean” for MBR partition


or win7 need mod for UEFI ,…but I don’t remember it :confused:

https://rufus.ie/ - for USB
and here try last win7 iso- https://www.heidoc.net/joomla/technology…o-download-tool

edit “fix for UEFI” or try google

I’ve already used both Rufus and DISM to install Windows 7. Again, I am able to boot into the installer, and select the disk to install to. After the first reboot, it gets stuck at the glowing Windows logo, and in Safe mode at disk.sys, whether through the reboot.pro method or with UEFISeven.
