WinNTSetup v5.3.3


Recommended Posts

Shrink the partition, create a new FAT32 around 100MB in size. Mark this one active and copy all boot files from your F: to it.

I  did the shrink and copied the files and looked at the BCD in \EFI\Microsoft\Boot\ and the disk and partition entries are blank again. Should I redo them  like I originally did above?

I redid a flash with Rufus with NTFS support and copied everything over. On the  first try, the boot started, but then complained about bootx64.efi missing, so I copied that over into \EFI\boot and got further. Now I'm stuck with the following error. Can't find winload.efi



I think the new Lenovo E15 is a 64-bit machine which is why I think the HW was looking for bootx64.efi. Could my problem be that booting a 32-bit Win 10 with UEFI is not supported on that machine?

If this is the case, will installing a 64-bit in the vhd be enough?

With the Rufus setup with NTFS, booting UEFI flash with 64-bit OS on a 64-bit machine now works via F12 boot menu, but  booting is ignored on my BIOS machine via F12 Boot menu. I have to boot it directly from my Bootit Bare Metal boot menu.  Not sure why though.

Try (on the BIOS machine that is NOT booting) to change the disk boot order (as opposed to F12 choice).

It is well possible that for *some* reasons either:

the stick is not BIOS bootable

the F12 menu in your particular BIOS is not an exact equivalent of the disk order change.

If the issue is the first, you can check it with grub4dos, that basically can boot a Windows (on BIOS) in three different ways;

1) chainloading the MBR (please read as "normal booting")
2) chainloading the VBR/PBR (please read as "bypassing the MBR")
3) directly chainloading the BOOTMGR (please read as "bypassing BOTH the MBR and PBR/VBR)

On a "properly setup" stick grub4dos should work in all three ways above.

Just shrink your C drive by 100 MB to 1 GB and create a FAT32 partiton from the new free space.
Ideally, but not necessary use diskpart's set id with c12a7328-f81f-11d2-ba4b-00a0c93ec93b to mark this partition a ESP.

Select this one as boot drive in WinNTSetup and install your Win7.
After you successfully booted Winows 7 to desktop you can select the same boot drive
but another partition and install your Win10.
