Rebooting off my live USB stick, which works. Also tried changing the boot order, so that it boots off the hard drive first. That didn't work. Tried Recovery Mode. Same error.
No, but I started fooling around in GParted, and now it won’t boot at all. I deleted the partitions, thinking maybe it had to do with those two options in the top right corner.
The video suggested I restore my BIOS settings, but that didn’t help me.
There has to be a way to fix this. Now I have a Hard Disk (3F0 ) error message. I thought if I deleted the partitions, upon reboot it would see that & suggest creating a new partition as part of the install process.
OK, really quickly…I disabled the Safe Boot & disabled TPM. I’ve included screenshots. Interestingly enough, I was able to boot off my USB stick once again, and I reinstalled Ubuntu.
Unfortunately I still have the same problem. Anyways, I opened up the terminal & typed in that command you told me to (sudo parted -l), and here’s the results (included in a screenshot).
