JFX Posted January 4, 2022 Author Share Posted January 4, 2022 How, is the partition layout? Many UEFI do have no NTFS driver, so you need a FAT32 partition that contains the EFI boot files. Link to comment Share on other sites More sharing options...
click-click Posted January 4, 2022 Share Posted January 4, 2022 (edited) One partiton as below. What do you suggest? Make a new flash as exfat or Fat32 Edited January 4, 2022 by click-click Link to comment Share on other sites More sharing options...
JFX Posted January 4, 2022 Author Share Posted January 4, 2022 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. \Boot \EFI \bootmgr 1 Link to comment Share on other sites More sharing options...
click-click Posted January 4, 2022 Share Posted January 4, 2022 (edited) 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? Edited January 4, 2022 by click-click Link to comment Share on other sites More sharing options...
JFX Posted January 4, 2022 Author Share Posted January 4, 2022 Yes, make sure they point to your NTFS partition where the VHD is located. Link to comment Share on other sites More sharing options...
click-click Posted January 4, 2022 Share Posted January 4, 2022 (edited) Same problem and still ignoring. Boots ok on the non-uefi laptop. Does it make any difference if secure boot is turned off? Edited January 4, 2022 by click-click Link to comment Share on other sites More sharing options...
click-click Posted January 5, 2022 Share Posted January 5, 2022 (edited) 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?

JFX Posted January 5, 2022 Author Share Posted January 5, 2022 Yes, you need an x64 OS if you want to boot with an X64 UEFI. 1 Link to comment Share on other sites More sharing options...
click-click Posted January 7, 2022 Share Posted January 7, 2022 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. Link to comment Share on other sites More sharing options...
jaclaz Posted January 7, 2022 Share Posted January 7, 2022 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 or 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. jaclaz Link to comment Share on other sites More sharing options...

JFX Posted January 13, 2022 Author Share Posted January 13, 2022 You need to partition your drive correctly, there should to be a FAT32 partition as boot drive. Link to comment Share on other sites More sharing options...

JFX Posted January 13, 2022 Author Share Posted January 13, 2022 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. 1 Link to comment Share on other sites More sharing options...
Sonic Posted January 21, 2022 Share Posted January 21, 2022 perhaps a new feature : DriveExcludedFromComboList= ? with same option as BootMountExclude= Because sometimes USB itself is choosen for Boot or install drive by mistake ! Link to comment Share on other sites More sharing options...
