Re: [gentoo-user] VFS: cannot open root device "hdd2" on unknown-block(0,0)

[Francisco Rivas]

Hi..

In my experience this error:

Error message on boot:
VFS: cannot open root device "hdd2" on unknown-block(0,0)
Please append a correct "root=" boot option
Kernel-Panic not syncing: VFS: unable to mount root fs on unknown-block(0,0)

is about bad configuration in grub/lilo, check the real number of your
root partition and remember: if you use Grub (great idea)  add the
real root partition number parameter to your kernel coniguration, plus
the init parameter.

This problem probably is the result of a change of your pool of disks
or changes in your partitions or bad parameter in you boot config
file..

That can help you i guess.

I hope help you...

P.D : Excuse me for my english i'm learning about it.

Have a VERY nice day.
