Repairing a boot drive question

[ExoMale]

Okay so my computer originally came with with Windows 8.1 so I'm still using it, however I have a 500gb storage drive I decided to use for Windows 10 upgrade while it was still free, so I installed my 8.1 and upgraded. Was fine at first booted in to that instead of giving me an option either drive, then I had to remove win 10 drive for use of the Sata port and was a few days before I connected it again.

So now after setting up my computer again properly I got a repairing drive come up on boot(my win 10 drive), but I can only boot in to 8.1, if I try boot Windows 10 I get an error with a prompt me to install disk which startup repair can't fix.


I can access the drive no problem as a second drive in file explorer on 8.1, but I'm wondering if I can fix the boot be it within CMD Prompt or other??



I tried googling, but not really the answer I'm looking for and reset is out the question(will need to disconnect my 8.1 drive first) as I've already had 1 win 10 upgrade fail after a reset(was selling a computer) making the OS come up with that inactivated error locking the key out, and don't know about you, but I didn't do the free upgrade to then pay for it after the end.

are you trying to run 8.1 and 10 using same license key?
when installing 8.1-> 10 on the 500, it was the only drive connected?

Yes I used my 8.1 with key on the 500(only my 750 storage was connected aswell) and straight away did the upgrade once all updates were done. I did make a post about whether there's be conflict, but that's not really there case.

After sorting Windows 10 I put back in my drive with 8.1 and booted up, instead of a boot manager like I assumed, it would just load up 10, then I had to take all the drives out at which point I then had only put my 8.1 back in along with a drive someone needed me clearing, then the 750 which I had put online to use it.

The moment I put my 10 back in upon loading it said about to repairs to the drive, so the drive is fine, there is just a missing/corrupt boot issue for that drive itself, I've been playing games so I haven't bothered with it, but I wanted to go on 10 earlier which is when I established the problem.


While I own 8.1 and the key, I don't need 2 versions on same computer and I'm not forking out £80 plus for a fresh win 10, the only reason I did it was because it was free and eventually to play xb1 games.
