Can it be done, if not hoe can I get grub back?

Yes, loads of ways, my favourite is this:

1. Install windows as normal.
2. Boot from your distro's live CD.
3. Open a terminal and use these commands:

Code:

sudo -s
mount /dev/sda1 /mnt
mount -t proc proc /mnt/proc
mount -t sysfs sysfs /mnt/sys
mount -t devpts devpts /mnt/dev
chroot /mnt
grub-install /dev/sda

Replace /dev/sda with your boot disk and /dev/sda1 with your linux partition.
4. Boot into Linux then run:

Code:

sudo update-grub

I looked at LM11, it sounds good, I could just upgrade.

Oh, almost forgot, step 4: Ater you've once again booted into Linux, run:

Code:

sudo update-grub

My preferred method is to restore the boot code ( you have a backup don't you? ) with dd.

Code:

dd if=boot.dd of=/dev/sda bs=446 count=1

Yes, very geeky. I know.

lol, you really backup your boot sector? I tend not to bother with stuff that takes a minute or 2 to generate.
