Here's what you should do:



1. Wait until April 23 to download Ubuntu. The next release is awesome, and everything works out of the box with the Eee PC.



2. After you've downloaded the .iso file, use UNetBootIn to ';burn'; the disk image to a USB stick.



3. Keep the USB stick in your Eee PC and rapidly tap Escape during bootup to boot from USB. This will boot a live session of Ubuntu. It won't erase Xandros yet.



4. In the live session, you can make an image copy of Xandros. But you have to be very careful. First of all, you'll need a backup medium (external hard drive, iPod, another thumb drive) that has at least 4 GB of free space. Plug it into your Eee PC.



5. Go to the terminal (Applications %26gt; Accessories %26gt; Terminal) and paste in the command



sudo fdisk -l



This will tell you what your partition table looks like. I believe the Eee PC Xandros will be called /dev/sda (with /dev/sda1 and /dev/sda2 for the recovery partition and user partitions, respectively).



Then paste in this command



df -h



This will tell the name of the backup medium. For this example's sake, let's assume it's /media/usbstick



Once you've figured out the Eee PC is /dev/sda and the backup medium is /media/usbstick, then you want to issue this command:



sudo dd if=/dev/sda of=/media/usbstick/xandroseeebackup.img



Now be VERY careful with this command. If you don't do it correctly, you can erase everything. I'll break it down for you.

';sudo'; allows you to run a command with system privileges. In ordinary Ubuntu you'd be prompted for a password. Since this is the live session, you won't be.

';dd'; copies partitions and drives bit by bit

';if='; specifies the input file to be copied (in this case, the entire Eee drive with Xandros on it)

';of='; specifies the output file where the copy will end up (in this case, as a very large file called xandroseeebackup.img on your backup medium.



After you've done that (the command may take a few minutes to execute), you can then close the terminal window and click the Install icon on the desktop and install Ubuntu right over Xandros. You won't need a swap partition, and you should use the Ext3 filesystem format.



Now, if you ever wanted to get Xandros back, you'd boot from the Ubuntu USB again and issue the reverse command:



sudo dd if=/media/usbstick/xandroseeebackup.img of=/dev/sda
