There are different types of bioses, but they basically work the same.
(to access bios, when restarting your computer, at the beginning you hit 'delete' or 'F2', or 'F8', or 'F10', of 'F12' - it should say which key takes you to setup)
You should find the option of "Boot devices" somewhere in the first two or three options. Once you find it, you will see it asking you to list your "boots" in order you wish your computer to read. There should be options like "IDE" or "CDROM" or "FLOPPY". You chose the one you want to be first, for example "CDROM" first, if you want to start formatting/installing from the windows cd.
If you can't find it, let me know how your bios looks like, and let me know what the options are. Then I, or another member will be able to tell you exactly where to go.
I'm trying to format my computer from a floppy disk, but I'm not sure how to change the BIOS so it can boot from the disk....can anyone help me? PLZ!
