Simply add --recheck

# grub-install --recheck /dev/sda

All the newer kernels see hard drives as sda rather than hda.

You can execute fdisk -l command to check device names assigned to disks.

i have checked using fdisk -l that it is hda.
i then change my bios settings and now my fdisk -l shows hdd as sda but still neither grub-install nor grub-install --recheck works.
everytime time i got that block device error.i google for the error but not able to find the soln.

What it the problem in keeping device as hda?
--recheck is not solution for your second problem, Actuallly you should create another thread for another problem..
"/dev/hda not found or not a block device" is the different problem.

Try to install MBR using grub shell..using command grub
then following commands on grub>

root (hd1,0)
setup (hd0)
quit

[devils casper]

If its showing sda or hda then execute this

grub
root (hd0,0)
setup (hd0)
quit

thx all,grub is installed but while booting windows it is giving error no 18.
i google n find that bcoz my partition is 100gb it is creating problm.
i don't think now there is a solution to that problem.to boot windows i have to put on windows bootloader again,i guess.

Grub Error 18:

Selected cylinder exceeds maximum supported by BIOS

So maybe you need to update the BIOS but since you have not posted your partition information from fdisk -l command it's hard to say.
