Error using cfdisk

[vikster007]

I'm trying to install knoppix. I use the command knx2hd. (I first press control-Alt-F1)

It tells me to partition my hard disk
I select the drive and then the screen goes black and at the bottom it says
"Opened disk read-only - you have no permission to write"

then i press enter and get the next error
"FATAL ERROR: Cannot get disk size
Press any key to exit cfdisk"

Then it takes me back to the menu where i choose to partition my hard disk.

thnx

try doing it as root, at the bash prompt just type root,press enter, then root as the password. then try cfdisk

ok from the bash promt i can get into cfdisk.

How do i use this thing though?

I tried making my whole drive my primary and when i try to install knoppix it still says i need to partition it.

I have a empty 15 gig hard drive btw

if i remember correctly, knoppix needs/requires 3 partitions. one for /root, one for swap & one for /home. (been a while since i used cfdisk)to start,click create,make your root at least 1gb (or more,may need room for expansion) swap needs to be at least 512mb (or double your ram) & the rest can be used as /home. once finished write changes to disk then continue with install.(think i got it right,working from memory someone correct me if i'm wrong)

good luck

Ok it seems that linux didnt like it when i tried installing text way but i did get it installed, I shut down the computer after it installed and when i tried to turn it back on it freezes at:

umount: devfs: not mounted

[vikster007]

Im using a laptop incase that helps at all

The lines it reads are:
mount: unknown filesystem typt 'devfs'
alps.c: Enabline harware tapping
umount: devfs: not mounted


It stops there I don't know whats wrong.
Thnx, Vik

You have a error in your fstab file.
You could fix this by booting up with your knoppix livecd and editing the /etc/fstab file .
Mount the partition and make it writable by right-clicking on it.

vi  /etc/fstab

Hit " i " to bring you to INSERT mode
Substitute reiserfs or whatever is correct for devfs.
Hit ESC to bring you back to COMMAND mode, type "ZZ" to quit and save your work.


Or you could just reinstall, using qtparted.

A /home is not necessary.
A swap partition is not necessary depending on the amount of ram you have.
256 or more, you should not need it.

A / partition is absolutely necessary

Hey

What should I substitute devfs for?
My fstab file looks like this:

/proc /proc proc defaults 0 0
/sys /sys sysfs noauto 0 0
/dev/pts /dev/pts devpts mode=0622 0 0
/dev/fd0 /mnt/auto/floppy auto user,noauto,exec,umask=000 0 0
/dev/cdrom /mnt/auto/cdrom auto user,noauto,exec,rp 0 0
#Added by KNOPPIX
/dev/hda1 ext3 noauto,users,exec 0 0
#Added by KNOPPIX
/dev/hda2 none swap defaults 0 0

I forgot to mention, I have 3 partitions

01 is ext3 2.93GB (this is where i have linux installed)
02 is linux-swap 509.88MB (I only have 128 mb memory)
03 is free 10.64GB

In the line for /dev/hda1 you don't have a mount point.
Put a " / " in there.

It should look like

/dev/hda1  /  ext3 noauto,users,exec 0 0

Use vi to do this as described above.
When you want to put the / in there, hit "i " to bring you to INSERT mode, put the slash in the appropriate spot.
Hit ESC to bring you back to COMMAND mode. Type ZZ to quit and save your work.
