This question already has an answer here:

I had three drives on my computer: C: D: E:

I installed Ubuntu 12.04 on the E: partition and now I'm using Grub boot manager to boot into Windows 7 and Ubuntu

I'm planning to install Windows 8 by removing Windows 7 on C:, but I don't want my old Ubuntu Installation to suffer.

Is there are way that after Windows 8 removes Grub from C: that I'm able to boot to Ubuntu again.

The last time lost Grub I used an Ubuntu live CD to reinstall grub ... worded pretty well. Just make sure you have a working Ubuntu live CD ready before you start to install Windows. I followed more or less the instructions here How to repair,retore or reinstall grub ...

It boils down to boot from live CD, mount ubuntu partition from HD, chroot and reinstall grub.
