so i have a windows xp cd which i burned with imaging etc
i have a compaq nc8430
i formatted using dos
format C:
i havent formatted in a while and i forgot this is a very bad way, so the partition itself is gone

when i boot up the cd everything goes fine until it says something like this
Setup did not find any hard disk drives installed in your computer. Make sure any hard disk drives are powered on and properly connected to your computer, and that any disk-related hardware configuration is correct. This may involve running a manufacturer-supplied diagnostic or setup program. Setup cannot continue. To quit Setup, press F3.
so i tried this thing called PE-builder but not quite sure what it does so that failed
im also trying this thing called ultimate boot atm but its still downloading so havent tried it yet
i also looked it up, it tells me to go into bios and change it to sata not raid etc but my bios doesnt have those settings it has some cookie cut bios and ive seen/know what bios is
just some extra info:
its a laptop with no floppy drive
has a cd/dvd drive
it was windows 7 ( but i wanted to have wins xp)
i have legit key of win vista business
i dont think compaq nc8430 has a restore factory push key (i wish it did -__-)
if u need any other info plz lmk thx
