OK, let me try...

0. Put your Recovery CD into CD-ROM.

1. When power on your PC, press 'Del' key to get into
BIOS menu. (sometime is F1 key or F2 key).

2. Find out where is "Boot Sequence".

3. Select CD-RM as "First Boot Device".

4. Save the change and exit. This will reboot the
machine.

5. After BIOS initialization, the system will boot
from the Recovery CD and display some instructions.

6. Follow the instruction and do a recovery.

Good luck.
