windows error- file not found- while installing with parallels 4

I can´t install windows on my macbook 10.6.1 through parallels 4. It stops at one of the last stages of the windows setup-process saying it cannot find certain files.

I tried to insert a screen shot here but i cannot find out how. This is all the info from the message.
C:\windows\system32\presetup.cmd-FILE NOT FOUND, and
C:\windows\system32\setupORG.exe-FILE NOT FOUND (setupORG.exe -> Original windows Setup.exe)

Possible cause:
1. ´presetup.cmd´ not exist in the i386 folder on UXPCD
´setupORG.exe´not exist in the i386 folder on UXPCD
2. Check your ´TXTsetup.sif´ in the i386 folder on UXPCD
presetup.cmd must exist
setupORG.exe must exist

Before starting parallels i made a standard 5 gb partition of my harddrive with boot camp.
I did not use any BETA software. Parallels tools are not installed.

I really hope somebody can halp me out here.
thanks a lot in advance.

 

Hello,

You can try creating an .iso image of the installation disk and then install windows with the .iso image, click on the link below to know how to create an .iso image.
