That was fast ! By Ram, do you mean the Random-Access Memory ? Well, I did add 1GB on the device before trying to install XP but would it actually have an effect ? I can't be sure that the HardDrive is in top condition as I received the device from a friend. Nevertheless, because Ubuntu and Seven (and most probably Vista) install without problem, I would say that it does work. I followed the method from this tutorial. What I did : - Copied the content of a Windows XP SP2 French in a "xp" directory on C: - Launched USB_MultiBoot_10.cmd. - Formatted USB stick using HP USB Disk Storage - In the main menu, pointed to source patch to the xp directory - Gave USB target - Proceeded to multiboot and copied sources to USB stick - When asked, copied XP+extras - When asked, gave the USB a U: Boot Disk status Once finished, I plugged the stick in the tablet device and selected the first option on boot screen. Installation process starts fine : I created a new C: partition for Xp to install on, formatted the hard drive and...when the actual installation starts, I get an error message saying that I have a "0 value to the section line [sourceDiskFiles], with the key binifix4.cmd". Only choice is to quit. Note that I think that on previous attempts, the corrupted file mentioned was different. When I use the same method with WinXP SP3 French edition, the installation process works but with majors errors : impossible to create or format the C: partition (the new installation just erases the old one), regular messages of missing files that eventually causes the graphic installation on reboot to fail. Note that when I reboot, I then select the second option from the boot screen to proceed with a regular boot in order to access the graphic installation process. Is that correct ?
