Question Boot from iso in ntfs hard-drive

hi all,
i use a compaq nc6000
i've been trying out several linux distributions and almost all boot nicely from a my cd-drive, none of which starts up my wireless though, but that doesn't bothers me right now.
i'm looking for help to boot from and iso stored in my unique ntfs partition.

i've followed the instructions in the link
h t t p : / / w w w . k n o p p i x . n e t / f o r u m / v i e w t o p i c . p h p ? p = 5 3 3 5 7 ,
but it doesn't work, it always displays thie error message:

Looking for CDROM in: /dev/hdh16
mount: ioctl: LOOP_SET_FD: Bad file descriptor
mount: Could not setup loop device
Can't find KNOPPIX filesystem, sorry.

thanks in advance for your help

Are you using a line like: bootfrom=/dev/hdh16
... then you must be booting from the knoppix CD.

Unless you put the loop file in another partition ...
this is because knoppix wants to look at the CD lopp file before switching over entirely to the ntfs image.

Looks like this is what is happening to you.

If you were using that line, you'd know it because of the effort you have to take to type it in. It is not standard.

It is possible to boot from an ISO already in the HDD ... there are not many advantages in doing so. (One is if you want a live-style distro and a free CDROM drive too, or to speed things up - but see "puppy linux")

My suggestion to you is to go through the posts from the start, only slowly. Make sure you understand what you are doing and why. (This should be treated as a technically challenging approach.) Then log what you do.

You need the ISO onfile (check)
You need to edit the bootfrom= line in... in... drat - forgotten.
You need to link to the loop file, also on the disk.
You need to keep reading the rest of the thread.
