I'm also trying to get a dual boot with Vista and xp to work on a Toshiba notebook with a factory install of Vista home. Im using 2160 OSS and it installs but does not recognize Vista. I end up with it only showing the secure zone as an OS. It will recognize the OEM Vista disk as an OS if I have it in the drive. I noticed a hidden partition at 1-1 on my hard drive and gave it a letter and then could see the contents of three files: Boot.sdi, Boot.wim, and winrepartition.ini. Then I had to change the letter back to none because otherwise I couldnt boot the computer back up. I think OSS wont recognise Vista because of the files on the partiotion with no drive letter but dont know how to get around this. Any ideas are appreciated.
