Knoppix 4.0 DVD HDD Install issue

Hi Guys,

I am a Linux Beginner and had various installations of knoppix and kanotix on my machine before.
After a while my latest Installation did not work any more so I decided to install Knoppix 4.0 on a new 20GB Hdd.

I made a 18GB Linux and a 2GB Linux swap and Knoppix installs everything without a Problem.

On a reboot from HDD I get this:

Uncompressing Linux... Ok, booting Kernel

and then

Kernel Panic - not syncing: VFS : Unable to mount roof fs on unknown-block(3,1)

The PC is a Fujitsu 700mHz with 256 MB Ram

I have excatly the same problem and cannot figure it out. I have tried all different ways and one time it did boot but could not find my ethernet connection. I am mostly using Mephis and debian and have no problems. The Knoppix live DVD works great but I cannot install it to the hard drive without the kernel painc happening. I have tried it on 2 different systems. I use sudo knoppix-installer.

Boot from the CD, mount the partition that holds the Knoppix install and post the contents of the file /boot/grub/menu.lst (from the mounted partition, not otherwise). Most likely the entry in the configuration file points to the wrong partition.

I had the same problem.

Try this.....It worked for me ....... I noticed that the boot sequence tried to detect my dvdrw as a hardrive and could not synchronize with it. I just changed the bios for my dvdrw to auto and removed the secondary slave hard drive.

# menu.lst - See: grub(8), info grub, update-grub(8)

## default num
# Set the default entry to the entry number NUM. Numbering starts from 0, and
# the entry number 0 is the default if the command is not used.
#
# You can specify 'saved' instead of a number. In this case, the default entry
# is the entry saved with the command 'savedefault'.
default 0

## timeout sec
# Set a timeout, in SEC seconds, before automatically booting the default entry
# (normally the first entry defined).

I am having the exact same problem as pt-1. My menu.lst file looks identical to the one posted above.

I am trying to install Knoppix 4.0 as a VMWare Workstation 5.0 image.

PC specs are:

P4 3.4GHz HT
2GB RAM

VMWare image is setup to use 512MB RAM, 10GB HD, and full processor power.

If anyone know how to remedy this, I would greatly appreciate it. Thanks in advance!

ich habe fast die gleiche Fehlermeldung:

Kernel Panic - not syncing: VFS : Unable to mount roof fs on unknown-block(3,3)

knoppix ist auf hda3 installiert.

hier der auszug aus der menu.lst:

was ist denn falsch daran?

So has any one actually found a solution to this problem yet

Same problem here.

I have installed the knoppix CD to /dev/hda2
I also found that when I do the following I have no permissions to /dev :

Code:

---

mount /dev/hda2
chroot /mnt/hda2 /bin/bash

---

There is something wrong with /dev. I got a lot of messages which says it has no permission to /dev/null.
Also grub couldn't find a harddisk (also permission problem, I think) and lilo gives me also permission problems. Seems that the installer don't create the /dev directory correctly.

I have tried to link the original /dev to /mnt/hda2/dev. But that doesn't the trick. I also tried to chmod 777 en chmod root:root (as long I'm logged in as root) the whole /dev. But it wasn't a succes.

I'm also stuck... :(

Hallo,
ich relebte auch das Problem "Kernel Panic - not syncing: VFS" mit KNOPPIX V4.0.2CD,
und eine Loesung gefunden. Habe gerade auch in einer anderen Stelle vorgestellt;

http://www.knoppix.net/forum/viewtopic.php?t=21272

Einfach den Eintrag " ### isk_size=100000 ...usw." in /boot/grub/menu.lst umschreiben wie folgt:
"ramdisk_size=100000 ...usw."

Mir ist nicht klar, ob dieses "###" absichtlich eingesetzt wurde oder wegen eines Bugs in knoppix-installer.
Jedenfalls hat diese Loesung funktioniert, mindestens bei mir.
Ich hoffe es kann Euch helfen.
