Borked Kubuntu Install. Best Mbr Repair Option?

[NegativeSpace]

So i got a new netbook which, as most of you know, comes with Win7 Starter, which leaves much to be desired. I used Unetbootin to make a Kubuntu netinstaller USB. Long story short, it didnt work and now my MBR is either overwritten or just missing or something. I had to use Lilo bootloader, because GRUB wouldnt work for some reason and it was already too late to go back by that point.

The question is what is the best way to repair MBR so I can use Windows, as well as try to install Ubuntu again without an op drive? I have other W7 machines on hand. If i try another technique for installing Ubuntu, is it possible that will repair the MBR and give me Ubuntu and Win7 bootable again?

It turns out that the wrong partition had been marked as the boot drive. I'm not sure how that happened but, after I had figured out that was the case it was obviously easy to fix. A new problem has arisen out of the situation though. Windows now reports a 320GB drive (pre format) as being a 45GB drive. Easeus Partition Master reports the correct size, around 300GB with 25GB being used, plus two small hidden partitions for recovery console and factory image. Has anyone seen this before?
