Background:
I have an Asus UX51VZ that will no longer boot into Windows. This was my dad's primary computer. I took it to a computer shop so they could fix the fans that came on at full speed all the time. I took out the two SSD harddrives beforehand to make sure they were safe. When I got the computer back, I put the drives back in, and everything worked fine for a day, then the fans started blowing hard again. I brought it back to the computer shop, but this time I left the drives in, thinking he might need them as he was going to try downgrading the BIOS. I didn't want to give him the password so he said he would use his own drive. Long story short he couldn't fix it, he refunded me, but it is now blue screening with my drives back in and will not boot.
Harddrive setup confusion:
This laptop supposedly comes with a RAID0 configuration for its 2 physical SSD drives (256GB each). There is a separate C: and a D: drive at ~237GB each. The BIOS SATA configuration is set to RAID. I can still see the folders in C: if I physically remove one drive and boot into recovery and command prompt. I can see the folders that were in D: if I enter into recovery with the other drive removed. Does this mean I'm not really in a RAID0 config? How am I able to enter recovery with either drive removed? Where is the recovery partition? What can I do to get more info on the proper hard drive setup?
Symptoms:
The laptop starts with ":( Your device ran into a problem and needs to restart." "Stop code: 0xC000021a."
Goal:
The data from both "C" and "D" has already been backed up. I am trying to recover the Windows installation 1) for fun to see if it's possible and 2) because I'd rather not reinstall all the programs that were installed.
Fixes I have tried:
It allows me to enter a recovery mode from where I tried:
Troubleshoot -> Startup Repair. Didn't work: "Startup Repair couldn't repair your PC." There is a log file at
C:\windows\System32\Logfiles\Srt\SrtTrail.txt
Command prompt:
cd to c:\ and d:\ drives and all the folder and files seem to be there.
-
bootrec /fixMBR [worked] bootrec /fixBoot [access denied] bootrec /rebuildBCD [Total identfied Windows installations: 0]
I then tried booting from a Windows 10 bootable USB drive I had laying around that had similar options:
- Reset this PC, keeping files. Fails at 1% and says nothing was changed.
- Command prompt:
-
bootrec /fixMBR [worked] bootrec /fixBoot [worked] bootrec /rebuildBCD [Total identfied Windows installations: 0]

Did all this with the help of: https://www.bleepingcomputer.com/forums/t/620701/windows-10-wont-start-unable-to-repair-bcd-of-raid0/
-
chkdsk c: /r
This repaired some bad indexes but there were no bad sectors.
What else can I try?
