Windows 10: Error 0xc000021a, on a dual boot system, one hard drive. any fixes?

Ive had two systems installed, 2 different versions of windows one is purely just for games, it is windows 8.1 which im aware that is out of support. And my main = win 10. I've had no errors until now. When this error happened:I was on windows 8.1. It has 1 partition out of the 3 total on my harddrive. I went into another partition, which I've been using before to store some files on while using windows 10.My win 10 were in 2 partitions: 1. System files etc, the partition with windows, and 2. downloads and etc, just files that i use. I made a 3rd partition, purely for win 8.1, for some games

vista boot error

Well, earlier today i was trying to setup a dual boot along with Xp and already had vista installed... so I made a partition on one of my HD's and went to install XP on it.. the instalation went back and I got an error that the CD was bad, so I rebooted and now I get the error Error Loading Operating System.. trying to figure out how to fix this.. I tryed playing in the BIOS along with using the Vista repair option but nothing helping.. my vista is on a different hard drive then where i tried to install XP to...not sure what else to do, I need to fix my boot file somehow... suggestions?

 

Windows 10 0xc000021a error -New Hard Drive

A few months ago I encountered the 0xc000021a error code. I’ve tried all the fixes that I could find, but none of them have worked. Would purchasing a new hard drive and installing Windows from a recovery disk fix this error?

Thanks
