plz make sure dat its not necessary tht the the parition on the 1st line of the grub entry and the root device be same.the entry o n1st line says from where the kernel image is ( i.e /boot ) and root= is ur root partiton which u make.
i hope this will help.
good luck

I forgot to mention the boot error.
RAMDISK: Coundn't find valid RAM disk image starting at 0.
VFS: Cannot open root-device "hda4" or unknown-block (0,0)
Please append a correct "root= " boot option
Kernel panic: VFS: Unable to mount root fs on unknown-block (0,0)
