I thought that I'd finally cracked it - I've managed to get One to recognise the USB stick and start the setup routines, but i'm now stuck on the error message: "Setup cannot access the CD containing the Windows XP installation files." Prior to that I'd deleted the Linux partitions and now have - c: Partitioned (NTFS) 7687MB u: Partitioned (FAT) 959MB I chose c: for the XP setup, and accepted "Leave the current file system intact", assuming that some files must have already been transferred. Should c: be formatted with FAT the same as u: (which I presume is my USB stick) ? How do I get the installation files over to One? Any help will be appreciated.
