I ran boot-repair and got this pastebin
The computer won't even let me run the BIOS without the USB I installed Ubuntu from plugged in. Interestingly enough, I formatted that USB drive right after I installed, so I don't know why it would even be a factor here. Any advice?
I had a similar problem when trying to fool around with a similar /dev/sdb device, my problem was that the sdb was trying to "start at boot" i cant remember what i did exactly to change it back. If you can access your desktop then go into the disks program and edit the mount options and remove the "start at boot" check box. Not sure if this will help, if you cant access the desktop somehow obtain a live cd, and you can change a config file somewhere but cant remember where.
