Actually not much. The backup will take up the most time (probably not
more than an hour at most... you *did* need to backup anyway right?

If you'd prefer you can choose to backup the MBR:
https://help.ubuntu.com/community/DualBoot/Mbr
but personally I'd backup the entire drive.
Reinstalling grub2 only takes a few minutes.

But I'd wait for Tom's further advise before doing anything else.
