This is my first post to your site, so please forgive i f this has been answered before. I did search the forums but did not locate this info.... I have a system created by my network admin whereby I perform an unattended install of Win2k or XP using a slipstreamed cd and a floppy containing NoAU.reg, pcbuild.bat, and a winnt.sif file. That worked marvellously until I ordered new pcs without floppies. How can I utilize the same system I had before but instead of the floppy use a usb drive? My new pcs support booting from the usb drive in the BIOS. Thanks for your consideration! Duke57
