Installed GRUB on a USB, after reformatting the computer won't boot when plugged in.
I'm not really a newbie, but thought that this question would fit best in here. I had the genius (not really) idea of installing GRUB2 onto my USB flash drive, then realized that it wasn't such a great idea after all. I reformatted the USB drive and after that my computer failed to boot when it was plugged in (presumably searching the drive for a bootloader that doesn't exist). It does not even get to the BIOS screen unless I unplug my USB.
Then, I tried doing
Code:
dd if=/dev/zero of=/dev/sdc bs=512 count=1
and I still have the same problem. I'm not really sure what to do at this point.

It isn't a bootloader issue. Just replace the stick.
See, it works perfectly fine as long as I don't try to boot with it plugged in. It was a very expensive high-capacity USB 3.0 stick, so I would rather not replace it if I don't have to.

UEFI motherboard ?.
Plug the stick in, and see if you can delete the boot entry for the USB from the "BIOS" boot list. If not, get a Linux system booted and use Intels efibootmgr to do the same.
