Yea, but on some laptops possible unlock hidden CMOS options - I have one

 

Fancy. Just wish that was the norm, instead of it being a hidden feature.

Yea, but using FlashBoot 3.3p not UefiSeven ?

 

If i use flashboot can i install the graphic driver after windows been installed ?

 

@Fed mo
Yes

 

UEFI class 3 is challenging.

My Asus Zenbook went through using UefiSeven.
But my Dell 7070 failed. Its install done, then reboot run into freezing-up at Windows logo, though its replacement of bootx64.efi was same as I did on Asus.

seems none could make UefiSeven working on Dell.

 

I feel like the lack of a UEFI GOP driver is the current big hurdle for windows 7.

Virtual machines do not need UefiSeven because they put Int10 (fake) into memory at C0000. OVMF does exactly the same as UefiSeven or Shim:

UefiSeven:

I am NOT lucky,

I tried files offered by @Gelip and bootmgfw.efi by @liliactr Thank you both.

my Dell 7070 SFF stuck at reboot after install when Windows logo start.

 

I also went through this procedure and tried it. Again, no luck.

It worked for Dell Vostro but NOT for my Dell OptiPlex 7070.

 

Change bootmgfw.efi at install.wim/Windows/Boot/EFI (not sure, some place in there)

I have used windows 10 boot.wim. If you do not maybe you need to change EFI partition bootx64.efi too.

Most of the acpi.sys files shared in here gives signiture error at boot. Signing removes error but replacing acpi.sys changes nothing in my all experiences. (I am using up to date install.wim)
