I have Windows 7 activated and I am trying to install Windows 10 on a Dell Precision Workstation

I am getting this error:

We couldn't install Windows 10 
We've set your PC back to the way it was before you started installing Windows 10
0xC900101 - 0x20017 The Installation failed in the SAFE_OS phase with an error during BOOT operation

But I don't want them to set it back to Windows 7, I just want it to do the freaking upgrade!

Just to elaborate a bit more on this - it appears to boot into WinRE instead of the set-up procedure, why would it do that?

I get to choose your keyboard layout and only the first page works so you can't choose US to see if that will help anyway.

This was definitely a driver problem - you have to be very careful which one you select for the C600 SATA Raid card!
