Windows, Bitlocker, And a GPU

[Christine_54]

The computer is a HP Elite 8000 SFF, I added a R7 240 to it but then bitlocker locked me out of the computer, so I now need to reinstall everything and somehow reformat the drive. And no I didn't backup the password for bitlocker cause I'm an idiot and didn't think i'd ever need it. Though here's atleast what i /think/ that I need to do, Please correct me if I'm wrong on anything
I'm going to first of all need to reformat the drive from BIOS or from a USB, which is 16GB.
I will then need to install windows 10 onto it, and again I have no idea what any of the internals are so yeah
Then here comes the insane speedbump, The fact I don't know the hardware and therefore don't know what drivers I need to install to make the goddamned system run in the first place, How would I go about doing this?
Can windows 10 even run without any system drivers in it, I'm guessing it can't cause that just seems insane.
I really need help here cause I've been without this computer since christmas...
Oh and bitlocker locked me out of it so yeah

Did it give you an error when it was booting into windows?

Because the latest version of windows will cause that if you're not using a TPM 2 chip for bitlocker

No it just opens that standard bitlocker screen

We can't help much for bypassing any type of security. We can't verify ownership of the device and anyone on the internet can make up a story. If you logged onto the pc with a microsoft account, you can get your key on there. Did you look at the other info on the bitlocker key faqs?
