Hi list,

I am using Mandrake 10.1 Official on multiboot system.

After installing Mandrake 9.2 (yes 9.2 NOT 10.1) on un-partitioned space. Windows stop booting.

Since as per default GRUB setting, it should show non *Linux OS also in Boot menu. But, here it is not showing any other OS.

NOTE: Boot loader might be installed on MBR (instead of first non windows partition)?

 So, I booted to Linux & can view non-Linux

partition being mounted as below:

#df-h

/dev/hda1 1G 4.7G 11G 31% /mnt/win_c /dev/hda5 5.1G 4.6G 418M 92% /mnt/win_d

and

#fdisk -l

Since, I am not getting any windows listing in my Grub boot menu.Therefore,i have manually added windows entry in it.

Now, 1)when I choose windows 2000 at boot time:

ERROR o/p:- Root(hda0,1) Filesystem type unknown,partition oxf Chainloader +1

2)When I choose windows 2003 Root(hda0,5) Filesystem type unknown,partition ox6 Chainloader +1

Lastly I tried installing Mandrake 10.1 Official…………Once again it could not able to recognise windows OS installed on my Hard Disk.

Now, please suggest how to revert back to my original configuration….. Running Windows OS without formatting. Since it contains lots many important installation that can’t be ported without running original Windows.

If you have installed Mandrake 9.2 after 10.1 then grub won't recognize your OS unless you manually change the grub.conf and point it to boot the newer (9.2) kernel.

Root(hda0,1) Root(hda0,5) ???????????? I think it should be (hd0,0) and (hd0,4)
