I have just gotten an external harddrive that holds 1TB. I want to use it as my main hard disk for everything... however I'm a little stuck on installing my programs on it. A lot of the programs depend on windows registry and system. Therefore, I must install windows itself on the disk. Is this possible by changing the main drive in BIOS to the external hard drive and then putting a installing windows? Also... I"m getting the upgrade of vista for my notebook so if its possible to put a bootlegged version of windows 98 on the external harddrive and then do an upgrade on the harddrive as well instead of buying the full version of vista for the harddrive as well as the upgrade for my notebook? What can I do to use the external harddrive as my main drive?
