Setup Mint from LiveUSB and fix bootloader
# Primary sources
# Install Grub2: http://community.linuxmint.com/tutorial/view/245
# Update grub2: http://askubuntu.com/questions/145241/how-do-i-run-update-grub-from-a-livecd
# Run LiveUSB in live or persistent mode. You'll need the terminal after installation.
# Install as normal. You'll get an error about not being able to install the bootloader, ignore and continue, do not reboot.
# If you do reboot, just get back into live mode and continue.
# Replace the drive/partition numbers where necessary in the code below and run the following commands to install/update GRUB2
#sudo mount /dev/sdXY /mnt
