Windows 10: Win 7 to 10 0x8007001F upgrade error

I have user that I've attempted to upgrade to Windows 10 but it failed with error0x8007001F. To date, I've upgraded at least 200 machines and counting using the same steps and haven't had a problem. All of them are Dell Optiplex models that support Windows 10. Steps I've taken so far are :

CHKDSK C: /F
Remove and re-install audio driver (suggested by Googling)
ESET Antivirus removed
also tried running as local admin account but no luck

I did notice that he has a strange empty E: partition that was created when I used AOMEI Backupper to clone him to SSD a while back. There seems to be nothing on the E:\ but it appears as a primary partition. Can I use partition software to remove it safely? It's the only thing that stands out to that would be different from all the other computers. Any ideas? Any logs I can check for details as to what may have caused the upgrade to fail?

Upgrade Windows 7 to 10 Error 0x8007001f





The partition layout of disk 0 (shown as disk 1 in Partition Manager) is non standard and was customized by the manufacturer. A normal Win 7 installation will have a layout:

1. 100MB System Reserved, NTFS format and marked as Active
2. C drive.

A normal Windows 10 installation will have:

1. 550MB Reserved partition, NTFS format and marked as Active
2. C drive.

Since you know how to use Minitool Partition Manager. Suggest to use it:

1. Create a bootable installation USB from the Windows ISO using: Rufus - Create bootable USB drives the easy way
2. Delete the 1st 2 partitions (102MB, 15GB) then create a 550MB partition, format as NTFS, label "System Reserved", assign a letter R, mark as Active
3. Move C drive next to the newly created 550MB. should look like the screen shot below, note H: drive should be C: in your case:
   
   
   
4. Boot up the USB created in step 1, on the first screen, press SHIFT+F10 to open the Admin command prompt then type:
   bcdboot C:\Windows /s R: /f BIOS =====> This will create the BCD to boot Windows and store in R: (550MB partition)
5. Reboot the PC then try to upgrade again

NOTE: It is advisable to create a backup image of the whole disk 0, just in case anything goes wrong then you can restore back before making any modification.
To create a backup image Use:
Macrium Reflect Free Edition x64
Macrium Reflect Free Edition x86
