Ubuntu – Accidently installed grub to usb


While doing a fresh ubuntu install (dual boot with XP using resize), I somehow managed to install grub to the source usb instead of to the harddrive. Normal harddrive boot goes straight to XP. Booting from USB leads me to grub. From there i can boot into ubuntu. Pretty cool actually, but not what I had in mind.

How do I install Grub to HD?

How do I recover my USB?

Best Answer

From your booted Ubuntu system, open a terminal, then use the following commands :

sudo grub-install /dev/sdX
sudo update-grub

Replacing sdX with the actual drive, which will probably be sda, but use disk utility to double check if you are unsure.
