Hey guys,

I have installed many versions of Gentoo on my machine before, but this problem has stumped me.

I made a few mistakes on my last installation and many things were broken beyond fixation/repair. So, I decided to just reinstall everything because it would end up to be less time consuming and it would actually work -- and also, I did a stage 1 install instead of a stage 3.

So, the first thing that REALLY puzzled me is that, out of nowhere, my hda changed to hde, and my hdb turned into hdf .. So, I just worked around it in the install manual.

I then configured GRUB, and being new to grub, I just did as the install manual told me. I did everything that should be working.

However, this is what I get when I try to boot my new install:

Code:

VFS: Cannot open root device "hde4" 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)


So, I am really out of ideas. I can post my config or whatever is needed to solve this problem. I will be eternally grateful if someone can solve my problem. Thanks in advance!

yes sir! :D

Here it is! :)

Code:

default 0
timeout 5
splashimage=(hd0,0)/grub/splash.xpm/gz
title=Gentoo Linux 2.6.5
root (hd0,0)
kernel /kernel-2.6.5 root=/dev/hde4


By the way, to confirm, I have made sure that the kernel IS in fact supporting ReiserFS (which is my root partition) (not as a module, but built in).

Thanks for the reply, li1_getoo :)

EDIT: fstab is here:

Code:

/dev/hde1 /boot ext2 noauto,noatime  1 1
/dev/hde4  /       reiserfs  noatime        0 0
/dev/hde2   none   swap   sw              0 0
/dev/cdroms/cdrom0    /mnt/cdrom  iso9660   noauto,ro   0 0
/dev/cdroms/cdrom1   /mnt/dvd       iso9660   noauto,ro   0 0
/dev/hde3   /home  ext3      noatime   0 0
/dev/hdf1    /storage  ext3    noatime  0 0

none         /proc        proc      defaults    0 0
none       /dev/shm    tmpfs    defaults    0 0


PS: I am hand-typing this so excuse me if I make a type-o somewhere :)

No, that didn't work :( Hmm

Anyways, it's late over here so I'm going to go to bed. I will check back on this thread tomorrow, so if you have any additional ideas, I can check it out tomorrow morning. I appreciate your help and I'm sure we can find a sollution to the problem! :)

Thanks again!

I added this into my fstab today and got it working:

Code:

...
...
...

none    /dev    devfs    defaults    0 0
none    /sys    sysfs    defaults    0 0


Using LILO I did:

Code:

mount /dev


right BEFORE:

Code:

/sbin/lilo


I have no idea why it was bitchin' about devfs, because this is my first linux distro and this is first time, out of at least 10 tries, that I got gentoo to boot. But, this gave it a quick kick in the jewels. :twisted: I hope it helps you in some way!

try reffering to your bootdisk as /dev/hda instead of /dev/hde

I know the livecd detected it different, but there are a lot of people with similair problems...

Try having a look at:

I changed everything from fstab information to grub.conf information as suggested and it worked splendidly! As suggested, I changed everything from hde* to hda* and it worked brilliantly! It is odd how the LiveCD detected them as hde but Gentoo itself detected them as hda ...

Anyways, I appreciate EVERYONE'S help in this situation! Thanks again!

Aman
