i am newbie to multiboot dvd and l believe l have completed the necessary steps (gone over twice). I have started as the tut recommends with 1 "cd" in particular windows xp pro service pack 2. cdshell get the bootloader fine however l get the following error straight after :

INF file txtsetup.sif is corrupt or missing, status 18.

l have checked the file exists and indeed it does however l have to reference to go any further.

any thoughts ?

The message tells you that there's something wrong with txtsetup.sif, so the first question you have to ask yourself is: Did I change that file?

If so, what changes did you make and could you have made an error in them?

Try comparing that txtsetup.sif with the original one and see what differences there are. And if there are differences, are they're all expected diferences. (You can use fc.exe to compare files or get a hold of a GUI based file comparison tool like WinDiff.exe)
