BleepingComputer.com: Vista won't boot (blinking cursor after splash screen)

Couldn't find a recovery partition so I think I probably don't have one! I don't know anybody with a Vista DVD (except perhaps a local shop but they'd probably charge). However, am I correct in thinking that if I download the WAIK then I can burn the disc image to a DVD and use this with my product key to reinstall?

For reference, the download I'm looking at is here:
http://www.microsoft.com/downloads/en/details.aspx?FamilyID=C7D4BC6D-15F3-4284-9123-679830D629F2&displaylang=en#AffinityDownloads

But seeing as it's nearly 1GB I didn't want to hit download until I know I'll be able to use it!

Thanks,
Simon
