    I tested my boot.wim (Win7 SP1) with UefiSeven loader in pure UEFI - works on virt-manager QEMU KVM with a standard vga.sys driver on OVMF 2016 firmware. I set emulated graphics card to VGA:

    I also tested on real PC on pure UEFI and works OK.

    i resolved that bluescreen. this siwndows 7 system boots with flashboot's bootmgfw.efi but not with uefiseven's.
    shame, because flashboot consistently screws up my resolution and makes the system unusable, but it DOES boot.
    unlike with uefiseven, where it doesnt boot at all.

    i think at this point, the problem is that windows 7 doesnt have a GOP/efifb video driver. regardless of the int10h emulation.

    I think this is not a problem with GOP because I use WinXP 64-bit with graphics card GOP in pure UEFI (CSM disabled) & patched acpi.sys:
    • FlashBoot 3.3n + standard vga.sys
    • UefiSeven + vbemp vga.sys
    I use Win7 boot.wim (WinPE 3.1) to install and also works with graphics card GOP in pure UEFI (CSM disabled) & patched acpi.sys:
    • FlashBoot 3.3n + standard vga.sys
    • UefiSeven + standard vga.sys

    I tested UefiSeven 1.24 with my boot.wim WinPE 3.1 (Win7 SP1) + patched acpi.sys + integrated USB 3 & NVMe drivers on real hardware with GPU AMD 7450 (GOP) in pure UEFI (CSM Disabled) + mouse USB and work OK ;)
