can't install slipXPprofSP2 from HDD

[wolfshade]

I am installing slipstreamed XP Professional SP2 from HDD and right after it copies files to systemdrive and reboots it asks for the original SP2CD.

P.S. Don't ask me why i am installing from HDD : I do this before i put it on CD to test the REAL THING (i always did this and no Virtual Machine can simulate it like i want it network and all).

Besides the rest of the structure is more complicated like answer file on floppy and postinstall files (after first logon) on HDD while the rest on CD.
