ACer Aspire... can't upgrade Vista

Hi All,
I am trying to upgrade my laptop to Windows 7 from Vista.

All the editions are compatible, but when it gets to the "Select device driver...", there is NO drivers to be selected at all.

Any help or direction, greatly appreciated.

Thanks
Dean

Thanks Jonathan,
After reading your post, I did a quick Google and came up with this link that walked me through:
How to boot from a CD Tech – for Everyone

Thanks so much for the quick response and point in absolutely the right direction. Owe ya a beer.

Installing as we speak............ keep you posted.

Gracias
