Windows 10 Won't Boot UP: Just Loads A Black Grub Screen with a >

Great news.

Yes just above the Quick reply box, where we have been typing. Should be an Orange Oval and a Green oval.

Your thread caused me to do some reading. I'm thinking it has to do with UEFI and its use of NVRAM. I would have to try some things to prove or disprove.

I'm going to guess if you go back in BIOS and go back to legacy booting you could swap disks. (Prevent UEFI) This would likely mean some messing around with the installs up to a reinstall. Saw a neat idea where you macrium reflect your entire drive, do a clean install (MBR) and then restore the Windows C: partition alone. All would have to be tested.

Should you stay with Windows please consider using a disk Imaging tool like Macrium Reflect. Free, reliable and saves a huge amount of time.

The ONLY thing that I really want to do is get the saved login info from Firefox. So I would want to just start up firefox, get saved passwords, and then get out.

Unfortunately firefox encrypts the saved login info so I can't just grab it while booting in to Linux.

Just copy the existing Firefox Profile.
When you reinstall FF you can copy the old Profile into the new one (replace the files).

You could also keep the new Profile and just add the old Profile using the Profile Manager.

Sometimes the Profiles are incompatible between versions.
I think that FF 58 Profiles are incompatible with earlier versions.

Remember to make a backup before you try it.

I shared my FF Profiles between my two W7 machines across our network.

I swapped to Pale Moon in 2013 and I still share my Profiles.
