Kernel Panic:VFS:Unable to mount root fs on Unknown block

Hi Everybody,
I am installing latest Linux Kernel 2.6 on machine which has Red Hat Linux-9.0 [Kernel 2.4.20]. I have followed all the steps required in building and installing a Kernel.

I am getting the following error at the time of booting new Kernel via Grub.

VFS:Cannot open root device "LABEL=/" or Unknown-block(0,0)
Kernel Panic:VFS:Unable to mount root fs on Unknown block (0,0).

I am new to Linux and needs your guidance to work out with this problem.
Please suggest me the possible solutions for this problem.

Thanks & Regards

"VFS:Cannot open root device "LABEL=/" or Unknown-block(0,0)
Kernel Panic:VFS:Unable to mount root fs on Unknown block (0,0)."

When you boot, all of the modules necessary to access / must be available to the kernel. You can either make these modules resident in the bootable kernel by specifying y in the kernel configuration or by loading these modules from /lib/modules/2.6 using initrd.

Personally, I prefer to set all necessary modules to y and dispense with initrd.

Be prepared. Create a LifeBoat CD.

this is probaby because you did not compile "in" the module for your FS...maybe you left it as a modular option.....anyhow this is how i solved such a message i was getting
