I bought a computer from cyberpower; every time I boot the computer it says something about invalid boot disk even though it doesn't even have a floppy drive and nothing in the cd drives. After a couple times of ctrl-alt-del the computer finally "catches" and boot proceeds normally.
Make sure that you have set the jumpers right and that your cd rom drives are slaves and that you only have one master. Check it for your hd and your other drives. remember, one master, rest are slaves.
I only have one hard drive, but i will make sure it is set to the master as well as the cdrom drives ( 1 dvd-rom, and 1 cdrw). Does this explain though, how reseting it 5x-10x will eventually get it to boot up?
There is a possible explanation on that it may mean your hard drive is failing and this is only a sign of things to come. Second option is you just have a floppy set in the bios maybe not actually set to boot from it but still have a floppy in your bios settings.
