fochizzle, i don't believe that is the same issue. brian_c's issue is that some drive letters are hidden in windows explorer. So I am moving your post to it's own thread.

Also you have Vista and this is a W7 forum but maybe someone can help as they operate very similar. Your Vista ISO should be on a bootable flash drive and in your BIOS you would want it set to boot to flash drive.

I don't know how old this article HERE is and I've never installed from a flash drive myself but you might look it over. To repair your OS would be similar to install, so you need it to boot to the flash.

Hi Fochhizzle. You need to specially format the USB flash drive to make it bootable, simply having the files on it is not enough.

I found this, it can probably help you: http://answers.yahoo.com/question/in...0145158AAb5MMq
