I have a few suggestions. How about at least a tiny little clue as to what kind of machine you have to start with.

Did you check to see if you made a bootable cd. ie. if you view the cd is there one big file or some directories on the cd.

So you're machines don't boot from the cdrom. Did you buy these machines with XP already installed? I'm just curious really. Anyway.. You don't want to disable booting from the hard drive, you want to change the drive boot sequence. This is just my preference and I do not need ultra security but I like to boot the floppy first, then the cd-rom and then hard drives. There should be a way to change the boot order or sequence within the BIOS. Of course if there is no media in the floppy or cdrom then it will simply skip those drives and boot the hard drive.

If you have set the cd to boot BEFORE the hard drive and still the cd does not boot then I would surmise that you did not correctly burn the .iso to disc. Have you tried to boot any other bootable cd's? How did you burn the .iso?

THERE'S ONLY ONE FILE ON CD(KNOPPIX_V3.2-2003-03-30-EN.iso).Thre are folders and files inside.But i'm not really sure if it is bootable or not.
Yes,I did try to change sequence of booting,it would didn't recognize Cd as bootable and skiped to HD,so afterwarsd I even tried to disable HD boot.Nothing helped.
How can I make sure my CD is really bootable?I downloaded above mantiond file and burnt it onto a CD.
Thanks for help guys.

If you see the iso as a single file on the cd you have not written the cd correctly, an iso is an image of a bootable cd.

In your cd writing tool, look for an option to write an "image" to cd and then look at the file type dropdown box and if necessary change that to iso then browse to the knoppix iso. Write the cd and you should be set.

There is a little problem, I have practice, thus when i set first cd-rom, and second hdd, it boots from hdd!!!(WinMe), so i set ALL options to cd-rom, and it boots from hdd !!!, then i set onother boot device to disable, and till that it boots from CD !. So It's not so easy like U mean

It was unnamed comp. with preinstalled(undemand) no-legal WinMe(without code

) thus I was about to install w2k there - my friend's new comp.

OK not sure if I follow you or not. The BIOS doesn't care about your drive boot sequence. It only wants to find something it can boot. So if your drive sequence is floppy>cdrom>hdd It looks at the floppy-Is there a bootable disc? YES-OK let's boot it then. NO bootable disk? -> on to the cdrom. Is there a bootable cdrom? -YES- OK let's boot it then. NO- OK on to the hard drive and so on............ I would tend to believe that you had your boot sequence set right but you did not have anything bootable in the cdrom drive. If I am wrong then you have the weirdest BIOS I have ever heard of. I would update it with a flash if it were mine.

Have you been able to boot your Knoppix cd in any other machines? I still suspect that it is not bootable. Of course I am wrong at least twice a day (just ask my wife).
