chromebook从usb启动

chrome os动不动就给我powerwash,要不就硬盘挂,不时需要用到usb启动,利用usb里安装的系统来进行检测,推荐用puppy linux(Tahrpup 6.0 ,其他都或多或少有问题,有的还不支持鼠标键盘。)

步骤:

1、进入开发者模式

2、进入访客模式,或者ctrl+alt+f2:

shell

sudo crossystem dev_boot_usb=1

sudo crossystem dev_boot_legacy=1

sudo reboot

用ctrl+I 可以查看信息,确保这两个都变成了=1

3、插上写入了iso的usb

4、ctrl+L 选择从usb启动

USB Boot

By default, USB booting is disabled. Once you are in Dev-mode and have a root shell, you can run:

sudo crossystem dev_boot_usb=1

and reboot once to boot from USB drives with Ctrl-U.

Legacy Boot

This device includes the SeaBIOS firmware which supports booting images directly like a legacy BIOS would. Note: the BIOS does not provide a fancy GUI for you, nor is it easy to use for beginners. You will need to manually boot/install your alternative system.

Like USB boot, support for this is disabled by default. You need to get into Dev-mode first and then run:

sudo crossystem dev_boot_legacy=1

and reboot once to boot legacy images with Ctrl-L.
