ok, this is the third system ive built so far, ive got a Abit AB9 mobo, intel 2 core duo, i gb ddr2, nvidia 7200 512 mb (core clock 400), 1 maxter sata hd, 2 dvd/cd +- drives. I start up my system go to the bios, make all the necessary changes to get ready to boot up windows. I set the primary or the first boot device to my rom drive, slam the disc in the tray only to get an error saying that there is no disc. WEll i put my HD bootable disc in the tray and it read that fine, i even got to a gui thingy to go in and change settings on my HD. the only thing i could think of is that my jumpers are set incorrectly on my ide drives, but im pretty sure they are set correctly. Or maybe its something in the abit bios that im not familiar with. Any thoughts or help would be great. Im deleting everything on my HD as i type, so as soon as i get done with that ill repost and give the exact error, srry for the vaugness. Error reads as follows: Disk Boot Failure, Insert System Disk and Press Enter. I put disk in, and nothing happens !
