Look for the number under the start column for Sec GPT table which is 15633375 in this example:localhost / # cgpt show /dev/sda To create the rootfs partition, we first need to calculate how big to make the partition using information from cgpt show. Partition the micro SD card:cgpt create /dev/sdaĬgpt add -i 1 -t kernel -b 8192 -s 32768 -l Kernel -S 1 -T 5 -P 10 /dev/sda Write the partition table and exit by typing w. This will create a new empty GPT partition table. Start fdisk to create a GPT partition table:fdisk /dev/sda Since ChromeOS will automatically mount any partitions it finds, unmount everything now:umount /dev/sda* Get a root shell as described in the previous section. For an SD card, click here () to magically adjust the instructions for the mmcblk1 device that an SD card will register as. Reboot the system to allow the change to take effect.Ĭreate a root USB or SD for dual bootingThese instructions are written for installing to a USB drive with the sda device, assuming no other USB drives are plugged in. Then type this to enable USB booting:crossystem dev_boot_usb=1 dev_boot_signed_only=0 Note: After enabling developer mode, you will need to press Ctrl-D each time you boot, or wait 30 seconds to continue booting.Īfter booting into developer mode, hold Ctrl and Alt and poke the T key. To invoke Recovery mode, you hold down the ESC and Refresh keys and poke the Power button.Īt the Recovery screen press Ctrl-D (there's no prompt - you have to know to do it).Ĭonfirm switching to developer mode by pressing enter, and the laptop will reboot and reset the system. You must be running the latest ChromeOS prior to installation. This is the recommended setup for those that just want to take a test drive, or don't want to give up ChromeOS. No changes are made to the internal eMMC drive, and your new Arch Linux ARM install will run completely from external storage. These instructions will create a dual-booting environment where you can switch between booting Arch Linux ARM and the stock ChromeOS. But I´ll need some help in knowing what to replace the download commands with to install MATE/Unity rather than arch-linux.įollowing are the commands that I followed from (I didn´t proceed with the Mainline Kernal option)Īny help would be greatly appreciated, thanks. I´m hoping that I could use this method to install MATE or Unity onto the SD card. I followed this procedure and was successful installing arch-linux onto an SD card and consequently loading it up by pressing ctrl-u. I don´t understand much of this, though it entailed commands partitioning the drive. I then came across a detailed set of instructions designed for my specific chromebook model to install arch-linux on a USB or SD card. I entered the shell command to enable USB booting (crossystem dev_boot_usb=1), but when I rebooted and held ctrl-u, it didn´t recognize it. Then I created a bootable USB with MATE using a Windows computer. I´ve tried the crouton method with many distros (unity, xfce, gnome) & releases (precise, trusty, xenial, etc), but the most stable & usable of them (unity-precise in my case) still leaves me with a lot of applications that don´t work properly. Hi, I´m trying to get the latest long term release of either MATE or Unity installed on my Samsung Chromebook.
