Boot from iso - "wrong fs type" Error
Hi, a little help for the newbie...
Finaly I started Knoppix 3.8 on my ThinkPad laptop using the pnpbios=off parameter, and now I want to boot it from the iso image on my harddrive, because from the cd it works terribly slow. But when I try the command line :
knoppix pnpbios=off lang=us bootfrom=/dev/hda1/knx.iso
it returns "wrong fs type, bad option, bad superblock on /dev/hda1 or too many monted file systems" and continues loading knoppix from the disk ( succesfully ).
I have only one fat32 partition, and lack of free space so I can't afford to make another partition for hdd install...
Thanks in advance for your support

That should have worked. When your are in Windows, be sure the ISO image is indeed called "knx.iso" and that the file is in C:\ and not in some subdirectory. Also, you may want to boot Knoppix from the CD and then issue a 'fdisk -l /dev/hda' to be sure your C: drive is indeed /dev/hda1 and not /dev/hda2 or /dev/hdb1.

the name of the image file is exacty knx.iso, the path is C:\, and fdisk returns that my win95/fat32 drive C:\ is /dev/hda1
I'm wondering if it will work if I uncompress the iso and use the fromhdd command, but as I said I have a lack of free space so cannot try it at this moment... I'm open for any other suggestions. Thanks for your time!

Can you mount the image manually? To do that, boot with boot: knoppix 3. Once you have a shell, type the following commands (everything to the right of the #'s are comments and do not have to be typed in):
Code:
mount /mnt/hda1 # mounts the C:\ drive (/dev/hda1) to /mnt/hda1
mkdir /mnt/knx # makes a mountpoint for the image
mount -o loop /mnt/hda1/knx.iso /mnt/knx # mounts the image via the loopback device
ls -la /mnt/knx # list the contents of the image
df -HTl /mnt/hda1 /mnt/knx # display the filesystem, filesystem type, and mountpoint
Do all of the above commands work? If not, which ones do not? What filesystem is listed for /mnt/hda1, for /mnt/knx?

Mounting is ok, this is what I get with those commands :
knoppix@1[knoppix]$ ls -la /mnt/knx

I think everything is just fine... ?
