In disk management, it will label the 100MB partition with EFI if windows is installed as UEFI. You see that Windows 8 had a bunch more info between items 'SMBIOS Version' and 'Windows Directory', and one of those things is 'BIOS Mode'.Īnd that link shows how you can tell a)from disk management and b)from a file setupact.log I really doubt this can be fixed by simple patching, because it involves changes in many parts of Winload booting code.It shows the difference between Windows 7 and Windows 8 msinfo32 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. 'port' requires at least file disassembling and patching, and 'implement' requires coding your own solutions, yes or yes. 16385, the boot failed and the BSOD 0x00000100 appeared.Īccording to the situation in the screenshot, is there a way to solve this problem?įirst of all, this doesn't qualify as 'porting' or 'implementing'. 16386 and it was able to boot successfully.īut when I ported the UEFI boot file of Build 7850 to Windows 7 Build.

Then I ported the UEFI boot file of Build 5477 to Windows Vista Build. I ported the UEFI boot file of Build 5219 to Windows XP Build. 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.
