restore MBR

[mr.g]

Dear Forum Members,

I have an old old IDE hard disk which contains a lot of important data and applications. It was taken from my previous computer. Now I installed it on my new computer so I can run the application I used to run.

Unfortunately I found the HD is not boot-able anymore. However, when I boot the computer with a live CD I do find the content actually readable. Is there any way to repair the MBR of a hard disk?

Hi,

I tried almost all the methods, but they does not seem to work.
When I tried "grub", the system tells me that I don't have grub installed.

Later, I tried:
*****
mkdir /ubuntu
mount /dev/sda /ubuntu
*****
the system returns:
*****
/dev/sda already mounted or /ubuntu busy
*****
then i typed:
*****
grub-install /dev/sda
*****
the system returns:
*****
/usr/sbin/grub-probe: error: cannot find a device for /boot/grub (is /dev mounted?)
*****

I did not really tried the install-withdraw method as it seems to risky for me. (the disk contains very important data) i did try up to the point that installer warn me the data might be deleted.

What should I do now?

P.S. The hard disk is a IDE hard disk.
