CRDWIN 4.0A BETA weirdness

I can create an iso from working bootable cd (xp-2600) in cdrwin, i can also burn that iso with no problems in cdrwin, if fact i have cdrwin verify recorded image…all working fine except for the fact that the @%#$@^# new disk won’t BOOT!!! the files are there no problem. it will function from within windows, but it won’t boot. im thinking it must be a cdrwin problem. the original disk, (created from an iso with cdrwin under w2k) still works great…

I am lost, please help

You don’t create an iso.
Use ‘backup Disc’ menu selection.
