Navigate to c:\\boot and run these commands:

bootsect /nt60 c:
bootsect /nt60 sys
bootsect /nt60 all
bootsect /nt60 sys /mbr

Try them all until your system boots."
It's funny that you say this because I'm actually using a Windows 7 disk right now to get a command line. I found a way to get it to allow a simple format C: command by unmounting programs that are currently using it. I hope by totally leveling the drive that it will erase the bootloader completely. If it doesn't, I'll try what you just typed.
Edit: Btw, just in case you didn't know, netbooks can only use a 32 bit OS and my disk is 64 bit, so I won't be installing Win 7. If this format works, my Win Xp should load!

Gotcha, good luck - hope that one way or another your problem will be solved.
BTW, you probably know this, but to get to C:\\Boot you type in 'cd C:\\Boot'

sudo dd if=/dev/zero of=/dev/sdX bs=446 count=1

The general MBR geometry can be found at wikipedia:

http://en.wikipedia.org/wiki/Master_...e-endianness-0

the "sdX" above is just a place holder, specify your specific drive; usually sda.

Trying to get back a previous bootloader is another question. Do you have a backup image of the Vista bootloader? Or, do you have another machine with the Vista boot code that you can copy over?

I know little about Vista, but I can show you how to manipulate MBRs all day long in Linux. If you have a copy of the Vista bootloader, you can write that back into the bootsector.
These instructions work from unbuntu or a live cd with similar structure.(Debian base I believe)

I bet that would've solved my problems if I did it from the beginning. Unfortunately though, like I said earlier, I've already formatted all 3 (dev/sda1,dev/sda2,dev/sda5) partitions and no longer have Ubuntu.

A live cd or recover cd for Ubuntu would work just fine as well. The syntax might change a little for a recovery cd. Either way, the premise is the same.

Well if you ever come across this problem again, here is the fix before you format the drive .

****, the boot loader doesn't effect whether or not you can install windows. In fact, it doesn't do anything to the drive but let you boot the OS. You don't have to format anything before installing another OS, really that's not how this all works. =S If you can't install windows on the drive it's a driver issue or a bios setting like I said before. If you want to use the drive as a spare then just format it to NTFS or whatever. Either way you are trying to fix a problem that doesn't really exist.

[edit] But if you really want to try and "fix" this, for whatever reason:

http://www.kernelhardware.org/erase-mbr/

No MBR = no problem! If you still can't install windows, or do anything, as I expect to happen then you know that I already told you this.

None of this would be difficult if I had a dual boot or previous Windows install, but I don't.
Not sure why you're frustrated with Ubuntu when you're having a Windows problem that has nothing to do with Linux.

That said, exactly what netbook is it?
