I recently ran into a problem upgrading a computer from Windows 7 to Windows 10. I received an error message with the following error code: 0x800703ed
It turns out this system was a dual-boot Linux and Windows system. I was actually booting to a different hard drive which had GRUB installed, and then GRUB was booting to my Windows drive. I fixed the problem by switching my BIOS boot order to boot directly to the drive with Windows 7 installed and then repeated the update process. This resulted in a successful Windows 10 upgrade. After the upgrade was complete I was able to change my BIOS boot order back to the way it was before, and now everything works fine.
Thanks – I ran into the same error, and this fixed it :).
Thanks, it also worked for me, easy 🙂
Hi,
unfortunately I use my computer since 2011 with the first Disk 0 as boot disk in bios, while my linux partition is the third on the same disk, so I can’t change disk in Bios.

This seetup work since 2011, and I upgrades from Windows 7 to Windows 8, 8.1, 10, 10, 10-17.03 without any problem. Only windows 10-17.09 upgrade fails with this error.
