I'm using an HP tx2514ca tablet PC running Windows Vista Home Premium as it's native OS, I tried to install Windows XP tablet edition on a 10GB partition formatted to NTFS. It loads up fine but once it actually loads windows to install it i get a blue screen saying "windows has encountered a problem and must shutdown to prevent damage to your computer" and thats the end of that. I got a similar problem while trying to install ubuntu, i would crash once the OS boots up because it thinks the computer is over heating, 60C is normal for hp tablets. mabye thats the same problem XP encountered
