Linux & Windows partition changes, boot fun

To remove GRUB from the MBR on primary disk in the laptop that hold Windows 7:

• boot with recovery DVD
• get to a command window
• issue commands to re-write the MBR

To write GRUB to the external HD containing Linux Mint:

• Boot Machine off Mint Live DVD (can't use virtual box for this)
• Launch GPARTED to determine disk and partition holding Mint
• Open terminal window
• sudo mount   /dev/sdb1   /mnt
• sudo grub-install /dev/sdb  --root-directory=/mnt

grub probe does report some errors but installation of grub works.

to refresh the grub menu on the external drive (if it needs updating...):

• sudo update-grub

to add an entry for linux into the Windows boot menu (otherwise one needs to get the boot list (f12 at startup)):

•
