blue screen on boot

Hello,
I have an XP installation that was working until 2 days ago. Then at next
boot an error occur. The system is rebooting every time during the startup.

I have tried to boot in safety mode, but it reboot automatically.
I have tried to boot in various of the possibiltity but it is always the
same result.

I have tried to boot selecting the option to avoid the automatic reboot on
error and I get a blue screen with a STOP error with code 0x0000007E and a
signal that a problem occur on the NDIS.SYS file.

Do you have any suggestion how to fix it?
Thanks

You have some form of hard drive failure. Boot to the XP setup CD. Press
ENTER for setup, not 'r', and accept the offer of Repair.
