My windows 10 pro pc stopped booting 2 days ago. It goes into the repair/diagnosing loop and an error of 0xc000021a. I went thru all the advanced options to repair it and the screen to disable options and that stuff. I do ok with computers but this has me worried.

How To Fix Windows 10 Error 0xc00021a

In my PC I have 4 hard drives and I kept a working Win7 Pro on one hard drive, the others are dedicated to music production using Win10 Pro as my boot operating system for all my recording software. It stopped working about 2 days ago after the computer froze forcing a reboot. May have been an update.

Using the bios I can boot into win7 fine and I can see all the win10 files on the hard drive. I had Microsoft support remote login today which was no help, they told me the only way to fix it is a custom win10 install and lose all my apps. They did the usual sfc /scannow stuff on my win7 drive and I stopped them and said I was in chat/remote for win10 drive problem. I have an assure plan and sometimes they make nervous it just seems so scripted.

There must be a way to fix this without forcing me to lose my current win 10 setup. If you have any ideas please let me know and yes I have searched google and youtube for fixes. Hard drive checks out fine it is no doubt a win10 startup issue.
