This question already has an answer here:
I found an old SSD and decided to use it for Ubuntu on my desktop where I only had Windows 10. I installed it and everything worked fine (dual booting, that is). Turns out that the reason the SSD was lying around was because it was broken.
So I figured that I would just remove the SSD and proceed with only Windows 10 but when I remove the SSD, I can't boot at all. I get into some sort of grub rescue environment.
As they were on different hard drives, I don't understand how I could mess up the Windows 10 SSD mbr?
Any suggestions for how to get out of this?
tl;dr Ubuntu on one SSD, Windows 10 on one SSD. I want to physically remove the Ubuntu SSD and only run W10. How?
