Hi,
The boot loader for all these partitions would have been in the master boot record, which was overwritten when you installed grub. I don't think there's an easy solution for this. The best would be to boot linux through the Win 2000 boot loader.
How do i do that,what addition do i have to make in windows 2000 boot loader and how do i make it default bootloader. Do i have to uninstall grub.
As Philip suggests, I the most sensible thing would be to use the Win2K boot loader. Here's the general way you can rescue your setup.
1) First of all boot into each Linux distro and install its boot loader to the first sector of its own partition. i.e. boot into debian and install grub/lilo to the boot sector of /dev/hda8 and similarly for RH9 to /dev/hda9. I use LILO myself so I can't give you instructions for grub - use the manual. Make a boot floppy for each on the safe side as well.
2) After both the boot loaders for the Linux distros are installed, while still in Linux, copy the first sector of each to a file like so: dd if=/dev/hda8 of=woody.img bs=512,count=1 dd if=/dev/hda9 of=rh9.img bs=512,count=1 and then move these two *.img files to C:
3) Now boot off the Win2K/XP install CD and go to the recovery mode console. Here you can log in as administrator and get a limited shell. Use the commands fixmbr (& fixboot if necessary). This will overwrite grub in the MBR with the Win2K boot loader and automatically make entries for Win98, Win2K & WinXP.
4) Now you should be able to boot into any of the versions of Windows and edit the C:\BOOT.INI file to add entries for Linux like so: C:\RH9.IMG="Linux RedHat 9.0" C:\WOODY.IMG="Linux Debian Woody" (note that the file is hidden/system etc. so unhide it first)
That's it - all 5 OSs should now boot ok. If you don't really know what you are doing, a mistake can be dangerous - you may then need to over-install Windows. So be careful....
