I don't think that the accessing or changing something in the BIOS will help.
However, if you press the right key for your machine (check the user manual, it could in principle be something else than you listed, for example DEL) and it doesn't work, it's a serious hardware error on the motherboard, totally unrelated to anything in Windows.
However, HP in https://support.hp.com/us-en/document/bph07110 says it's F10 or F1 (if "older" means from 2005 or earlier). But check the moment you press it.
If repair doesn't work, you'll need a refresh or reset. Make the correct Windows 10 install disk or stick using the Media Creation Tool (google that, if necessary), boot from it and go ahead for the recovery options.
However, it could be that you need to access the BIOS to tell it to boot from the DVD or the stick. That depends on the current settings for the boot priority.
Have an older HP desktop running Win 10 Home 64-bit. Last night while browsing web in Chrome, PC went BSOD and rebooted to the "Attempting Repairs" loop.
Have tried to boot to bios multiple times, but that doesn't happen and it just goes right back into Attempting Repairs. Yes, I've tried F10, F2, F11, Win/b on startup but none are recognized or acted on.
Any ideas whatsoever would be appreciated.
