I really doubt this can be fixed by simple patching, because it involves changes in many parts of Winload booting code. This is very early in the process, because this crash doesn't even appear in WinDBG (kernel support for it still hasn't bee initialized when it occurs). That's because there was big change in the way the memory is mapped by Winload and then passed to NTOSKRNL during early kernel initialization stages. Second, Vista Beta Winload is incompatible with Win7 in both x32 and 圆4 versions. You are just transplanting files between windows editions.

Windows 7 requires Secure Boot to be Disabled, Legacy ROMs to be Enabled and in any case does not have an Updated Microsoft Signature to pass Secure Boot. To boot to UEFI or BIOS: Open the firmware menus. Until the 32-bit UEFI boot appeared again at build and has been retained to this day, the build is also the first Windows system to support exFAT boot.Īt present, I have successfully implemented 32-bit UEFI booting of Windows XP and Vista, but I still cannot achieve 32-bit UEFI booting of Windows 7. The first Windows system build to support UEFI-IA32 boot was, but this feature was removed by Microsoft after building. Of course, versions earlier than Windows 8 still require CSM support by default when UEFI boot. ![]() This feature is ported from the Windows beta.Īlthough it is officially claimed that only Windows 8 and later versions support x86 UEFI boot, In fact Microsoft introduced 32-bit UEFI boot support as early as the beta version of Windows Vista.
