    Whenever I try to boot from USB the Win7 installer I get “Windows failed to start.” \EFi\Microsoft\Boot\BCD - 0xc0000001 - ‘An error occurred while attempting to read the boot configuration data.’ Image updated installer with drivers boots and installs up until the first restart, and throws the same error. Even after replacing bootmgfw.efi with the renamed file, I still get this error?

    Dell Inspiron 15 5593, Core i7-1065G7, GeForce MX230, 16GB DDR4-2600MHz. No option in UEFI for CSM.

    I didn't find "uefiseven.skiperrors", only 2 files inside "uefiseven_1.30.zip" :
    1. Bootx64.efi
    2. UefiSeven.ini

    I really don't like that error telling me every time
    "Could not find Windows Boot Manager at '\EFI\Microsoft\Boot\bootmgfw.original.efi'
    Press Enter to continue"

    Do you know how to slipstream Nvidia driver into my untouched Windows 7 media to make it fully bootable on UEFI class 3 machine ? Do you know also where I should go to get that driver ?

    Once the INI file is opened, you can be happy with it.

    I opened the ini file, changed
    skiperrors=0 --> skiperrors=1
    Then put that file inside :
    B:\efi\boot\
    B:\efi\microsoft\boot\
    ( B:\ is where EFI partition located ),
    Still the error message shows up every boot

    Edit : someone offered an advice for using windslic in conjunction with UefiSeven, but after deploying windslic loader, the error message keeps showing up every boot.

    It appears that rearm wizard is the real solution here to activate my Windows 7 ultimate on gigabyte motherboard, but its links were already dead, what should I do right now ?

    Nothing works I am also trying to install it on ryzen 5000 series laptop and get the c000 error on the uefiseven
    also when using safe mode I see it get stucked at classpnp.sys
    Did anyone tried cloning a VHD from virtualbox to a new partition ?
    Maybe installing the drivers on vm and after, cloning to a partition

    Hi. Is it compatible with Windows Vista? Sounds logical, but I wanted to ask anyway. Thanks.

    Yes it is! I used this on a 2014 Dell Latitude E6530 with a Windows Vista and Windows 7 dual-boot on a 4TB SSD (about 2TB per drive) with UEFI enabled. For this, I had to enable initially a hybrid mode of UEFI and Legacy, but after I got into Windows, I was able to set it to pure UEFI with no issues.

    Just note that Vista usage is experimental at best. I tried this with Vista on a 2019 Acer Aspire A315-21, whose hardware has Windows 7 drivers still, and it wouldn't load. When I tried it with Windows 7, it worked, but my AMD Radeon R4 Stoney Ridge graphics driver would not install despite the modified one I was using having worked in Legacy Mode. Weird.

    Also, I tried to install Windows 7 to my UEFI only Lenovo ideapad 3-15ITL6 Laptop - Type 82H8, which has 11th Generation Intel Tiger Lake and Intel Iris Xe graphics, but when it rebooted after installation, it froze at the starting windows logo. The ISO I used has updates up to 2020 along with other stuff such as USB3 and NVME. It also uses the Windows 8 WinPE instead of 7's. I can get through the first half of setup, but when it restarts, it shows the windows logo in dots (not fully formed) but then freezes there. IDK what else to do.

    Hi All. Anyone got things to work with VirtualBox or Hyper-V? I have disabled VGA and inserted drivers for both the virtual display cards in VirtualBox (VEN 80EE & DEV BEEF) and Hyper-V (VEN 1234 DEV 1111) and still got stuck on the starting Windows screen. Thanks.

    VirtualBox does not have any INT10 code, at least the version I'm using (5.2.45). It behaves like a class 3 UEFI. Of course, there might be other deficiencies or missing features.

    VBox uses firmware video Legacy (55 AA):

    This is not UEFI Class 3 or UEFI+CSM:
