is there anything on C drive you want to rescue? try making this on another PC: http://www.howtogeek.com/howto/windows-vista/use-ubuntu-live-cd-to-backup-files-from-your-dead-windows-computer/
Also, on another PC, download the
Windows 10 media creation tool and use it to make a win 10 installer on USB - its a handy boot disk if nothing else
turning everything off in msconfig isn't always a good idea. especially following some guy on a video...
lets see if startup repair helps
change boot order so USB is first, hdd second
boot from installer
on screen after languages, choose repair this pc, not install.
choose troubleshoot
choose advanced
choose start up repair - this will scan PC and maybe fix this - will ask for logon info
if that doesn't help, try safe mode:
boot from installer, on 2nd screen after languages, choose repair this pc, not install
choose troubleshoot
choose advanced
choose start up options
hit the restart button
choose a safe mode (it doesn't matter which) by using number associated with it.
PC will restart and load safe mode
If you get into safe mode, right click start button
choose run...
type msconfig
reset it to normal startup and restart PC and see if it works
If neither of these help, you might want to use ubuntu to copy anything off PC you can't afford to lose, and do a reset
boot from installer, on 2nd screen after languages, choose repair this pc, not install
choose troubleshoot
choose reset this PC
choose keep files/settings (this should work, i don't think it saves msconfig settings) - other choice is wipe it all
EIther choice, PC will restart and reinstall win 10. It only effects C drive so other hdd would be ignored. You need to reinstall applications again
If reset doesn't work, do a full install using Win 10 installer
boot from installer
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)
hopefully one of those will fix it before you need last one
