Disabled Graphics Card -- Now Black Screen

Good Evening,

I recently accidently disabled my Graphics card under Device Manager and it straight away turned my screen black. As you'd expect, but I was curious if it prompted a reschedule time to reactivate the disabled graphics card. Which it didn't, and now I'm just stuck in black screen with no idea what to do. I've tried BIOS by taking the little watch type battery out waiting a couple of minutes then reinserting but that doesn't do anything when rebooted, no messages or prompts. I'd like to use safe start but I can't see nor hear anything which makes it very difficult. So any ideas on how to fix? (Not too tech savy so go ez)
 
Press F8 repeatedly as the computer starts. If you can see anything select VGA Mode reboot the computer
