Re: Reinstalling Ubuntu 12.04
you currently ARE using grub2 to boot into both...don't worry, just reinstall it. By the way, you should consider how you will install it: if you make the automatic install, also delete your SWAP partition (because the old one will remain, so you end up with 2 swap partitions). Also be careful to not touch the windows partition!
Follow these advices and you will fine
