On another PC, download the
Windows 10 media creation tool and use it to make a win 10 installer on USB
broken install is result. Ideal solution is a fresh install. Need to wipe ssd first to get past that error
change boot order in bios so USB is first, hdd second
boot from installer
on screen after languages, choose repair this pc, not install.
choose troubleshoot
choose advanced
choose command prompt
type
diskpart and press enter
type
list disk and press enter
this shows all drives available, DVD/USB and hdd, make note of ssd number
type
Select disk X - where X is the number of the ssd you want to wipe, change X to that number and press enter
once the drive you want to install on is chosen, type
Clean
restart PC and installer should run,
follow this guide:
http://www.tenforums.com/tutorials/1950-windows-10-clean-install.html
when you reach the screen asking for licence, click "I don't have a key" and win 10 will continue to install and reactivate once finished
On the screen where you choose where to install win 10, if it gives you an error about GPT drives, delete all the partitions on the hdd and press next. If it still gives error, cancel out of the installer and restart PC and start installer again, it will accept next on that screen this time (some PC just need a restart here).
