Fedora 11 live media and eeepc

[4gb]

I start the Fedora 11 live media on my eeepc and it looked good,
so I decided to replace the Ubuntu system I had on it with the Fedora one and clicked on the Install to Hard Drive icon.

Unfortunately at the partition formatting stage, the install crashed, I tried a couple of time and it always crashed at that stage.

I have a XP partition on this PC and since the /boot partition has been wiped out, I can't even boot on the XP partition, just stay with the GRUB prompt, my question is:

Is it possible to recover this from the fedora live media ?
Is there something like 'fdisk /mbr' or something else I could do so I could at least be able to boot up XP ?

If I remember right, the XP setup of the installation CD has an option to repair the MBR of an existing XP installation.
