Create X5000 boot medium from a system backup

Here I describe my procedure for creating a USB boot medium from a system backup for the X5000. In my case, I did this with a USB3.0 card reader and a 4GB CF card.

Step 1:
I connected the card reader with the CF card plugged in to the top right USB port on my tower.

Step 2:
Start MediaToolbox and select "usbdisk.device". If you haven't already done so, prepare the CF card with "Reinstall". Then click on "Edit partitions and filesystems". Create a partition in the new window. I created two partitions, each with 2GB. For the boot partition, select the standard file system with long file names. Click on "Accept changes", then "Save to disk". I then unplugged the card reader with the CF from the USB and restarted the computer.

Step 3:
After the computer has booted up again, reconnect the card reader with the CF to the USB. Now format the CF card. The system can now be copied to the CF card. I chose a backup of my system that was pre-installed on my X5000 when it was delivered.
When the copying process is finished, please make sure that you remove everything from WBStartUp and do not show any references to partitions other than "Sys:" in the user startup or deactivate everything except "MUI" and "tbimages".

Step 4:
Restart MediaToolbox and after selecting "usbdisk.device" under "Edit partitions and filesystems", tick "Bootable" and increase the "Boot priority" or set it to "5" for example. Then finish the whole thing again after "Accept changes" with "Save to disk".

Step 5:
Leave the card reader connected to the USB port and perform a cold boot. As soon as the boingball appears, hold down the "space" key until the options menu appears. Then press the "B" key, a new selection appears, then press the "M" key. If everything is correct, the X5000 automatically resets the USB stack and then scans all USB ports. The CF card inserted in the card reader should be recognized and the system should be loaded automatically from it. This process takes a little longer because the CF card is not read as quickly as the internally installed SSD. Finally, the "emergency backup" should have started and you can restore your system to the state it was working before.
