hi there i am trying to create an unattended xp cd out of my xp pro cd.
i did copy all the contents of my xp cd to the desktop, started nlite, added my add ons,
removed ( games-internet games,wallpaper,languages,music samples,old cd,tablet pc) only.
i created my ISO, but when i tried in vmware i got this message:

error
the signature for windows xp professional set up is invalid
the error code is 800b0100

no signature was present in the subject


fatal error
set up failed to install the product catalogs.this is a fatal erro.the setup log files
should contain more information.

any help on how to fix this wull be greatly appreciated.

I would look at the addons you may be adding. I was getting the same error except I was using RVM Integrator and a faulty post-SP3 update pack was causing it. Once I took that update pack out everything worked fine.

You're best bet would be to start slow. Just get the addons working first, and then start tweaking and removing things. Working in VMWare it's easy to set up a VM session snapshot staged to boot from your ISO image. After you run a test, just revert back to the snapshot.

What addons are you using?

thanks alot for your answer.these are my add ons:
7zip
adobe reader
avg antivirus
crap cleaner
dotnetaio
irfanview
izar
klite
opera
unlocker

i tried without removing anything and it worked, i really dont know why removing
unnecesary stuff like wallpapers,screensavers,music would affect the installation


+by the way the first time around i also replace the original BLISS file with my own
as well as the background using winntbbued.

thanks once again.

I would focus on the replacement Bliss wallpaper and the Winntbbu file, but you cannot rule out the things you're removing.

Take things in sections. Try these tests:

1. Addons + New Wallpaper
2. Addons + New Wallpaper + New Winntbbu
3. Addons + New Wallpaper + New Winntbbu + Remove 1 component

Try the first combo and see if it works. If it does, move on to the second combo and so on.
