¶ Imaging
¶ Acer C720 Chromebook
- Plugin the Imaging USB Stick and boot the Chromebook.
- Should automatically boot from the USB drive, but you can hit Esc to go into the BIOS if you need to change the boot order.
- The USB drive contains a GParted LiveCD and a partition with the disk image. Select the first option.
- Press Enter several times to boot with the defaults.
- Once booted to the GUI, open up the Terminal. For our purposes, /dev/sda is the Chromebook SSD and /dev/sdb is our LiveUSB disk.
- Validate which partition is the data drive. It will be the larger of the two formatted in ext4.
- Mount the data drive containing the image
mkdir /tmp/usbsudo mount /dev/sdb1 /tmp/usb
- Write the image file to the Chromebook SSD
sudo dd if=/tmp/usb/AcerC720.img of=/dev/sda bs=1M status=progress- The imaging will take about 8-10 minutes.
- Once the imaging is complete, press the power button and shut the Chromebook down.
- Power the Chromebook back up. It should automatically boot into the image and into GalliumOS.
- Once booted, modify the laptop hostname to a unique name. Our convention for these laptops is
ctrlh-loaner-cxxwhere xx is a number. - Connect the laptop to the CTRLH Wifi.
- Shutdown and return the Chromebook to the storage box.
