An old laptop was donated to a friend of mine. When he turned it on it said "Disk boot failure insert system disk and press enter" it was on a black screen. He then installed Windows XP. He said it worked fine. When he turned it on again the next morning it said the same thing again boot disk failure etc.... The laptop is NCS Technology (that's the only name on the laptop). Could it be the BIOS? Please advise. Thank you!
