|Ar you SURE the hard drive is dead or is failing ?|
The bios not finding a bootable hard drive doesn't necessarily indicate that.
That problem can be caused by....
- you don't have the network boot option in the correct place in the Boot Order or similar settings in the bios Setup
- you DO have that set correctly but
- the bios is not detecting your hard drive at all
- or - the bios is detecting the hard drive but it's not finding that it's bootable (has an operating system installed on it)
Also - reasons why your hard drive may not be detected as bootable by the bios.
See Response 1:
Your bios / main chipset doesn't have any hard drive size restriction. You can replace the hard drive with any size (capacity) of new SATA hard drive.
If the Vista DVD or the Recovery disk(s) don't detect the new hard drive, Vista has some SATA drive controller drivers built into it, but not all possible drivers. If it doesn't have the right drivers built in, the SATA drive may not be detected by the soiftware.
In that case see this - it's a similar situation for Vista except that you can provide the drivers on other media such as a USB flash drive
Installing XP and SATA drive controllers, SATA drives; the SATA drive controller bios settings.

In most cases the hard drive is easily accessible under a plastic panel on the bottom of the laptop's case. It's usually a rectangle just a bit bigger than the size of the drive
