Hi, I am trying to install a version of XP (modified with NLite) onto a laptop without a CDROM and it cannot boot from USB. I have taken the HD out, put it in another computer and ran the following command: winnt32.exe /syspart:c: /tempdrive:c: /noreboot /makelocalsource With the HD back in the laptop, textsetup now loads - but displays an error similar to the following: no previous version of windows NT can be found. Setup cannot verify that you can install this upgrade. The CD I used is a full version, and is not an upgrade edition. It worked fine on another computer with a blank HD, just causes an error when setup is run from a HD. Please help me to resolve this - it's really bugging me Thanks
