I'm attempting to help a friend of mine who's laptop has been on the fritz as of late. It appears the OEM hard drive has had it and some system diagnostic tools on board confirmed the hard drive was on its way out. Picked up a new SATA drive and plugged it in last night and booted from a Windows XP disk. Once all the Windows components load and you have options to Repair or Install, if you select install a new screen displays stating that there is no hard drive detected. This was also the case when I tried to re-install Windows on the original OEM hard drive. However, from the BIOS you can use a system utility to check the hard drive and that operates just fine. I feel like there must be some driver or other component I'm missing that isn't loading up when booting from the Windows CD. Can anyone help?
