BSOD Driver IRQL Not less or equal on Windows 10 Bootup

Hi,
I originally posted this question on another answer website, and somebody started helping me and then stopped. I would really appreciate help. Here is what was discussed in the other website.

This was the original post by me.
Hi,
I installed Rollback RX yesterday because I wanted to roll back windows 10 to windows 8.1 (Wish I originally had). Since then, when I boot up, It comes up with the BSOD Driver IRQL Not less or equal.
I tried reinstalling windows 10, but it said the HDD was locked. I contacted Microsoft and they headed me to Asus (the makers of my laptop), who were no help at all.
I need my computer, it has inportant stuff on it. I have just spent the last 4 hours looking on fixes for this, but I get nothing.
I know my way around computers and am happy to go deep into the BIOS or CMD
Please Help,
Thanks

Then this is my discussion with him.

Hello 7malligk

This tutorialmight be of some help.

Feel free to come back if more assistance is needed.

Cheers!!

Hi,
The screen comes up on bootup.
I can't access Safe Mode.
Even through the Advanced Startup Options, It still shows the BSOD, before I get to safemode.
Thanks

Hello again

Can you try Resetting Your Windows to Factory Defaults?

Hope this helps.
.
When I try to do that, it says the HDD is locked. I can't even do a system restore, automatic repair, refresh your PC, or Reset either! :-(

Hello again 7malligk

A few fixes are needed to unlock the HDD and reset your PC. This link will help you get it done.

Cheers!!

Hi,
Thanks for the time and thought,
but when I followed the steps in the link you posted I got this,

Sucsefully scanned Windows installations.
Total identified Windows Installations: 1
[1] C:\Windows
Add installation to boot list?

I selected {Y} (Yes)
And then it said

'The requested system device cannot be identified due to multiple indistinguishable devices potentially matching the identification criteria.'

Hello again

Do you have any USB peripherals like keyboard, mouse, printer, etc. connected to the PC? If so, can you please disconnect them and then try again?

Cheers!!

Nothing is conected to the PC

Hello again 7malligk

Hello again 7malligk

You can learn this from here.

Hi,
The partition with the OS is the active drive already, the others are all 'unactive'.
But, suddenly windows started coming up with this error, witch I hope will help you in diagnosing the issue.

'Your PC/Device needs to be repaired.
The Boot Configuration Data for your PC is missing or contains errors.
File: EFI\Microsoft\Boot\BCD
Error Code: 0xc000000f'

Hope this helps,
Thanks for all you have done so far, it is really greatly appreciated!


Hello again 7malligk

This link shows how to rectify the error by rebuilding the boot record.

Cheers!!

Hi,
I tried that but on the first step with bcdedit C:\BCD_Backup
It just said
The requested system device cannot be identified due to multiple indistinguishable devices potentially matching the identification criteria.
UPDATE! I tried it again and this time it worked, but when I got to 'cd Boot', it said file not found
Thanks for all you have done,
Thanks

PLEASE HELP ME! :)
Any help would be very greatly appreciated.
Thanks,
