BSOD | C000021a {Fatal System Error} after chkdsk

Error :

Code:

STOP: C000021a {Fatal System Error}
The initial session proces or system process terminated unexpectedly with a sta
tus of 0x00000000 (0xc00000001 0x00010710).
The system has been shut down.

This happens when i choose the option to not restart upon error, else it just keeps loop booting.

It started after i realised my HDD was acting weird so I went to do a backup, but windows said i needed to run a chkdsk first because of corrupted files. After it completed (took around 12hrs) I can no longer boot.

I can't run in safe mode or last known good configuration unfortunately.

I don't care about the OS, the biggest priority is to recover the files, I don't have another HDD or another CPU.

How can I solve the issue or salvage my files?

Thanks, Gabriel.
