I've found a number of tools for writing a Windows XP install to a bootable USB drive, but they all remove the customization from nLite. The target computer lacks a CD drive (it's technically an IO Server, that can run typical OS's). Thus far any attempt to install my custom version has failed, from using an IDE-based CD drive with an IDE to USB cable to the assortment of Bootable USB creators. I've been working on this for 12 hours, with no luck.
Is there any solution to this? I've thought about removing the Hard Drive, but getting the thing open is in and of itself a task, and once inside I have no idea what kind of drive it has or how to get it out.
