my windows 10 drive is corrupt after i booted from a windows 7 drive, startup repair starts up but fails

hello,

a while ago I had to find a file on a different drive then that was in my computer. so a put it in and and booted up the OS that was on it, windows 7. for some reason it started up disk repair even though it worked just fine in my laptop (wich broke thus i had removed the drive). but otherwise all went fine. it booted and I got the file i need, and then I shut down to boot from the windows 10 drive.

thats when things went downhill, it couldn't boot for some reason. I don't exactly remember what it sai, but I thought it might be fixed if I would remove the windows 7 drive. it did not. so I thought startup repair would do the job. but even that didnt work. in fact, I noticed it starts a windows 7 startup repair, I do have an older installation of windows 7 on that drive, but I don't think that should matter, its all under a windows.old folder.

i am at loss and have no idea how to fix this without having to completely reinstall. any help would be appreciated.

Things are tangled up big time. The two OSes have tangled each other. You might need to do a reset of Windows 10 which will preserve your data file but you will have to install all drivers and apps over again. Also get rid of that Windows 7 install before you do this.

so with a reset, do you mean a clean install? or am i missing something?

what exactly is that data file? and did the 2 OS's from the different drives tangle, or the old windows 7 on the same drive as 10?
