Ahhh, that makes sense. I assumed it would work in the same way as the winnt32.exe. I did think about doing the fdisk'ing and formating from within my batch. only problem is it has to be NTFS. There is also another issue i thought of. Once the installation has completed coping the files from the CD to the c drive it reboots and needs to boot from the c drive to continue the installation. At the moment it will just keep booting back to my CD, and running the batch file over and over. The normal windows installation seems to get around this by adding the boot up message to the beginnning of the cd saying 'Press any key to boot from cd', then if you dont it boots from the HD. I dont have this and so far havent been able to figure out how to do it.
