Once booted to rescue mode and at the command prompt type chroot /mnt/sysimage then cd /boot/grub and vi grub.conf. Alternately, chroot /mnt/sysimage and then vi /boot/grub/grub.conf.

Those are examples of Linux operating system device names that were used for IDE hard drives (/dev/hdx) and SATA/SCSI hard drives (/dev/sdx) before the time when the same libata driver code began being used for all drives which were then given device names in only the /dev/sdx format. In Fedora, the change occurred with the release of Fedora 7. No changes occurred to Legacy GRUB's device naming scheme. It still uses the same old (hd0,0) format for designating drives.

Thanks stoat.
Would someone please explain the GRUB's (hd0,0) format?(meaning)
HTML Code:
(hd0,0)
And why GRUB's (hd0,6) was indicating sda7 (so(hd0,5)=sda6) in that case(in my problem)?

GRUB and the operating system designate drives and partitions in very different ways. GRUB uses numbers starting with zero to designate the drives and partitions. The operating system uses letters starting with "a" to designate the drives and numbers starting with one to designate partitions. You have to get used to doing a sort of mental conversion when dealing with this issue. I didn't invent this system.

HTML Code:
splashimage=(hd0,5)/boot/grub/splash.xpm.gz
hiddenmenu
And
HTML Code:
