[ltp] Restore WinXP MBR?

Well, I did get this to work. I ended up making a CD equivalent of a DOS 
boot disk using tools from http://www.nu2.nu/bootcd/ and then just doing 
fdisk /mbr. I didn't know the linux fdisk could do this as well, so 
that's helpful for the future.

As for the questions below, at the time I was trying to do this I had 
just wiped the drive with the IBM restore CDs, so there was just WinXP 
on there. However, the problem with the reference to a Windows install 
cd below is that there is no such thing shipped with a ThinkPad (and I 
don't have a shrinkwrapped copy of XP).

Back to that issue that got me into this mess in the first place though: 
has anyone tried to dual boot linux and Windows using grub as the first 
bootloader? I.e., grub is installed in the MBR and ntldr is only in the 
Windows partition? All the dual boot howtos I've seen say you have to 
have ntldr go first, which is OK but annoying.
