I was having issues with the my graphics card (BSOD related to atikmdag.sys), to fix this problem I was directed to clear all existing drivers using "Display Driver Uninstaller" and using the latest drivers from the AMD website I updated and restarted. Now, Windows refuses to boot, giving me a new BSOD, with the error code "STOP: 0x0000007E". (At this point, attempting to start in Safe Mode is IMPOSSIBLE, it will always loop after the BSOD to the Windows Error Recovery screen.) When attempting to fix this problem I discovered my C: drive is now a RAW File System, this makes it impossible to boot from it because it's not a recognised file system. This has been a train wreck of trying to fix and just breaking it more, I'm tired of this so I could use a bit of help :(
Any possible solution that may result in data loss (Formating) is my last resort because of sensitive data. Thank you for reading.

Can we have your system specs please?

On top of this, do you have an iGPU or are you using an AMD CPU that doesn't have that? If you do have an iGPU available to use, then remove the GPU completely from the system, then try to boot into windows using the iGPU. If you can then not all is lost. You can then attempt to fix issues with drivers from here, however, assuming you can get in this way, I would recommend using it as an opportunity to do some backing up of important files so that you can then continue through with a clean wiping of the drive and a fresh install of the OS and drivers and such.

Unfortunately, I don't think I can do that, this laptop was issued by a company and so it's not letting me access any BIOS I'm used to looking at. All that is available is a HP start up menu, and in here there is no section that allows me to disable the on board graphics card.

Does your company have an IT department? If yes, they can look for a solution.
Do you still have your Windows 7 product disk?

Have you tried the steps in this article? https://www.howtogeek.com/135005/how-to-use-a-windows-installer-disc-to-back-up-your-files-when-your-computer-wont-boot/
