Bitlocker and driver verifier=Tons of problems

New to this forum, and this is my first thread. Please provide me with some help if possible.

So my problem is the following: Kept getting BSODs from some driver inflicting with ntkernel according to whocrashed and bluescreenview. Anyways, disabled my network card as I thought that was faulty, updated all my drivers and checked my ram with memtest just to be sure. Was still getting the BSODs.

Decided to use driver verifier to see which driver that caused this. Bad idea. Turns out that one of the drivers indeed was faulty, but now I'm getting blue screen before I can even log in to windows. Tried to boot into safe mode a thousand times by repeatedly pressing F8 and shift+F8 to no avail. Thought that I then could turn of driver verifier from the command prompt, but No! (Since if I could turn this of the BSOD before system start would then stop since the purpose of windows driver verifier is to force the faulty drivers to create BSOD).

Then downloaded EaseUS Recovery Essentials to see if that could help. Turns out that my ENCRYPTED (bitlocker) drive on which my operating system is on, can't be found because I'm assuming that the change in boot order previously when running memtest disabled it.

Now had to find my win8 installation CD to force it into safe mode alternatively to re-install it, but to no avail. It says that the hard-drive is still locked even though I've got the key in a USB stick attached to the computer and even though I manually put in the recovery key. Was now to give up on fixing this and tried to do a clean install on the SSD drive, but then it says that "Windows cannot be installed to this disk. The selected disk has an MBR partition table. ON EFI systems, Windows can only be installed to GPT disks." Assume this is because of the bitlocker encryption. So tried to format the drive but it won't let me since the format alternative is greyed out. The SSD with the operating system on is labeled as "Drive Partition 2" and there is another 350mb labeled "Drive = Partition 1:System Reserved" right above it that could be formated. Don't know if that would make a difference?

I'm out of ideas and don't know what to do anymore.. I can reach command prompt with the win8 installation cd but I don't know how to turn of driver verifier from there or if it's even possible if the drive with the OS is not reachable. On top it says "Administrator X:\windows\SYSTEM32\cmd.exe".

Ps. Was not sure where to post this since there seems to be a number of problems here that combined are making it hard for me to fix.

Update: Tried unlocking bitlocker on my C drive with the commandprompt of my X drive(windows installation USB) with this formula:

1. Open CMD as administrator
2. type:
   1. manage-bde -unlock *DRIVE LETTER*: -recoverypassword YOUR-BITLOCKER-RECOVERY-KEY-HERE
   2. manage-bde -off
3. now you have unlocked and disabled BitLocker
   
   Did not work. "-recoverypassword is not recognized as an internal or external command, operable program or batch file"

So, I've found a good guide on how to disable driver verifier ioutside the windows environment:
Disable Verifier Outside Windows (Vista / 7 / 8) - Sysnative Forums

I assume I still need to disable bitlocker though, through the same command prompt in order for the above to work, otherwise the drive will still be encrypted and it can't reach those settings..

Anyone know what to do?

update: Been working non-stop on this but I'm not getting much wiser. I unlocked bitlock with the commandprompt in the recovery environment with this code:manage-bde -unlock *DRIVE LETTER*: -recoverypassword YOUR-BITLOCKER-RECOVERY-KEY-HERE. Then used this: manage-bde -protectors -disable *DRIVE LETTER*: and then finally this:manage-bde -off I: . My Drive letter was *I* since code: dir:I showed that my windows was stored there. Finally checked it with manage-bde -status which confirmed after some time that all drives were fully decrypted. (it doesn't automatically show you the progress of the decryption).

Proceeded with cancelling driver verifier by the same steps as in the link above. Loaded registry from my system to the recovery option registry, then ran regedit.exe to delete two verifydriver keys to prevent the program from starting during boot-up. Checked it again using code verifier /query which says no drivers are currently being verified.

BUT, Windows still won't repair and still doesn't want to log me into windows. Blue screen says NO_BOOTABLE_DEVICE_FOUND but all my drives show up in bios..

However, I can re-install windows now by formating my SSD disk, which at least is some positive news. Before it wouldn't even detect the drive but now I see free space and total space in the columns which would indicate that the drive is no longer encrypted and that it isn't faulty?

When I try to reset PC it says ->Unable to reset your pc. A required drive partition is missing.
When I try to refresh my PC it says->The drive where windows is installed is locked. Unlock the drive and try again. HMMM..
When I try System restore->To use system restore you must specify which windows installation to restore. Restart and select an operating system then select system restore.
when I try start-up repair->couldn't repair your pc


All this because I ran driver verifier without backing up the system in advance with bitlocker enabled on my OS SSD drive..
