Question HELP: Upgraded to Windows 10 Pro, turned on BitLocker, and now get Windows Install prompt on reboot

[Jumpem]

The "Upgrade" option tells me to remove installation media and restart. I am not using any installation media though.

The "Custom" option brings up a list of all of my drives. I select the SSD that Windows is on and get "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. Windows cannot be installed to this hard disk space. BitLocker Drive Encryption is enabled on the selected partition. Suspend BitLocker in the Control Panel, and then restart the installation."

I am unable to boot into Windows to do anything in the Control Panel. The "Format" option for the drive is also grayed out so I can't do that.

I took the flash drive out and rebooted. It prompted me for the BitLocker password. It then appeared as if Windows was going to load, and then I got a blue screen with stop code "unmountable boot volume".

I restarted again, and instead of entering the BitLocker password, pressed esc for the "BitLocker recovery" option. I entered the key from the BitLocker Recovery Key .txt file and get "Failed to unlock with this recovery key".

If it shows umountable volume do I have any options other than reinstalling?
