Chrome Cr-48: installare Mac OS X e Windows 7

Il Cr-48 è il notebook appositamente studiato per il sistema operativo di Google, Chrome OS.

è equipaggiato con un processore Intel Atom N455 e grafica integrata X3150 ed è dotato di un apposito pulsante, collocato nei pressi della batteria, che evita il caricamento automatico di Chrome OS per permettere agli utenti di accedere al BIOS e di installare un sistema operativo alternativo.

Si può così installare un sistema operativo diverso. E’ quindi possibile installare Windows 7 o Mac seguendo questa guida:

  1. Remove the casing of your Cr-48. To do this, you need to remove the battery, and the rubber towards the back of the underneath of the device. Doing this exposes two extra screws. Unscrew all the screws you can see on the underneath of the device. Once you’ve done this, the device should pry apart, starting from the back under the screen hinge. Work your way around, starting with the side with the SD card slot on. Be very careful when you do this, as you don’t want to break any of the tabs that hold the casing on.
  2. While you have the device open, go ahead and turn the developer mode switch on. You’ll need to do this to run the Luigi installer.
  3. Once the casing is removed and you’re in developer mode, lie your Cr-48 on it’s screen and plug the power cord in. Now press the power button, and then when you get to the recovery mode screen, press Control-D to boot into developer mode. If it’s the first time you’ve booted into developer mode, it’ll take around 5 minutes to erase your stateful partition. Everything is in the cloud, so you shouldn’t lose anything, remember?
  4. Once it’s booted, connect your WiFi and make sure you can get onto the internet.
  5. Press Control-Alt-F2 (Control-Alt-Forward) to open a shell. Login with the username “chronos”, no password is required.
  6. Once you’re at a shell, simply type in the following command and press enter: wget && sudo bash run-luigi
  7. Luigi will then download and run, and present you with a screen with a small disclaimer. If you accept this, press enter to get to the main menu.
  8. You now have two options. Press 1 to flash the custom firmware, and then press enter.
  9. At this point, the custom firmware will be downloaded and flashed. Once it has finished, provided there are no errors, it will tell you to press enter to reboot.
  10. That’s it, your device will reboot and the new firmware will be installed.
  11. Once you’ve verified the new firmware is installed and works, put your device back together.
  12. From here, you can plug in a USB stick/USB CD drive and install an OS of your choice.
