Boot to rescue mode. Step through the process. When you reach the command prompt type chroot /mnt/sysimage. Please post the output of the commands /sbin/fdisk -l and cat /boot/grub/menu.lst.

chroot /mnt/sysimage
cannot change root /mnt/sysimage no such file or directory

/sbin/fdisk -l
/sbin/fdisk no such file

even cat command is saying no such file..
but just fdisk -l is showing
disk /dev/sda :400gb
..some stuff related to 400gb hard disk..

disk /dev/sdb:40gb
device boot start end block id system
/dev/sdb1 * 1 25 200781 83 linux
/dev/sdb2 26 4870 389174621 8e linux LVM

You must be getting a boot menu. Choose Fedora and press 'e'. Tell me what drive / partition Fedora is trying to boot from. You'll see something like root (hd1,0). Tell me what that actually says.

[shanmuga_k72]

its root (hd0,0)

[glennzo]

If you installed Fedora on the second hard disk, /dev/sdb (Primary Slave in Windows speak) then it should likely be root (hd1,0). You can change that on the fly by editing it using the method I suggested to view it. Edit that line by pressing 'e' and make the change. Press enter and then press 'b' to boot. The change will not stick. In other words, when you reboot you will have the same problem. See if it works and let me know. If it does work I can show you how to make the change permanent.

[shanmuga_k72]

its saying cannot mount the partition if i use root(hd1,0)

[glennzo]

Did you leave a space between root and (hd1,0), like this, root (hd1,0) ??

[shanmuga_k72]

yeah i left the space

[glennzo]

Well, you could try root (hd1,1) or root (hd1,2) but I think that these are unlikely to work. Probably worth a try since it takes very little time to actually try. Looks like the problem may run deeper than this though. Give it a shot and check back here.

i tried.. did not work...

thanks for ur post.. unforchunately that is not my problem...1 thing i forgot to tel u.. in rescue mode i m not able to reinstall grub.. i,e ggrub-install command is not found.. so many other commands are not working like whereis etc..

[glennzo]

Should be a simple matter of grub-install /dev/sda. If you chroot /mnt/sysimage and can't find /boot or any of the other folders and files then there is a bigger problem. More than just re-installing the boot loader.

shall i install f10 again????
