compaq presario 5000, model 5BW220, made 7/19/00. i installed a new hard drive on my computer because i think there's something wrong with the original. i have a new xp home oem installation cd that i want to install onto the new hard drive. the cd won't install xp home onto the drive. i only get a screen saying something like: "no operating system found, please press any key to try again". i think that i need to boot from the dvd drive that the xp home cd is in in order to install xp home onto the new hard drive, but when i go into bios the only two options to select to boot from are the A floppy drive and the C hard drive but no option for the dvd drive. how do i select to boot from the dvd drive if indeed that's what i need to do? also, if i am able to install xp home what are the next steps to take to get my computer running. my understanding of computers is pretty rudimentary. thanks for any replies.
