CD/DVD Device Driver Missing On 7 Starter Install?

about a month ago, my Windows 7 Starter went dead on my Toshiba NB250 netbook. At first I thought it was a HDD issue. I tried using downloaded 7 recovery tools to no avail, and for some reason, whatever took out the OS, took the factory installed recovery partition with it..After a few days, I was sick of waiting for the recovery media to arrive, so I tried Installing Ubuntu Netbook 10.10. It worked, so I assume the HDD is fine.The recovery media is on dvds, so it's useless to me (for some reason my BIOS doesn't support a boot from an external dvd drive). I got an iso of windows 7 starter. I've seen a ton of threads and responses where people say that the iso may be corrupted due to a bad download. Mine's fine, because it installs and runs in VirtualBox no problem.

I used the microsoft USB startup creation tool through my virtualbox installation. Thing is, whenever I try an install, I get a message saying there is a missing cd/dvd device driver. The thing has no cd/dvd drive, so I don't know what that's about. I tried copying the iso contents onto another piece of media, and did not make that bootable. I tried an install from my bootable usb, and then plugged in the usb of files. Nothing.I found this download on cnet, because I read about some guy who was messing around with his drivers to get an install to work. The cnet download was apparently only for vista, and when I put on my non-bootable media, and tried to install it when Windows asked for it, the installation told me that something was up with the drivers. Something to the tune of "contact the manufacturer for the newest software".
