Please check the "Analyzing the problem" in that URL,
It might give you the clue for your issue.
Besides, compare before copying anything.

I just took a chance by  chaning kernel input from /dev/sda2 to /dev/hda2

like bellow

 /boot/vmlinuz-2.6.24-etchnhalf.1-686 root=/dev/sda2 ro vga=788 acpi=off

to

 /boot/vmlinuz-2.6.24-etchnhalf.1-686 root=/dev/hda2 ro vga=788 acpi=off


it worked fine

thanks
