why not to just do a grub-setup /dev/sdX on the server drive putted in the VAIO, and then return it to the server machine?

Ok...well, I lied. I get a tad obsessed when I don't figure things out quickly. I have been working on it and finally figured it out (with the help of everyone here). You see, I forgot to zero out the drive before re-installing Ubuntu and especially GRUB. But then I had another problem...GRUB wasn't installing properly...so I tried it from the command prompt and it gave me the error that I wasn't seeing during the installer. It had no partitions! (duh) So I simply used fdisk to create a partition and then used grub-setup and grub-install to fix grub.

And it's a done deal! It works successfully. Once again, thank you everyone. You know, I read somewhere that if you wanted to get into Linux you will learn more (than you ever wanted) about how your computer works. And this is very true, except I've always wanted to learn these things...I had never opened up a PC before talking to you guys. Hopefully one day open-source will dominate the market and keep Gates and Jobs from telling us how our OS is SUPPOSED to run!

Thanks again!
