Another non-boot question

[neofile]

I have 3.4 downloaded as an iso and burned to CD, files as follows:
/boot
/KNOPPIX
/LinuxTag
/Talks
autorun
autorun.bat
autorun.inf
cdrom.ico
index.html

The disk does not boot. Everything that should be there appears to be there.

I have 3.3 from a magazine, which boots fine but the file layout is different. I can also autoboot Suse from a CD burned from the iso image, no problem. Just this one which will not boot, PC goes directly into XP instead. Any ideas?

Thanks

Forget it dodgy CD ... burned it again and it works fine
