When one is using a Chromebook, they can forcefully get it into recovery mode by pressing Esc+Refresh+Power. This will then display a recovery screen.
I’ve had a couple of friends tell me that I can boot from a USB flash drive, in recovery mode, as long as I have the disk image (
.iso) of the operating system on the USB flash drive. Is this true? If so, does it do any "damage" of sorts to the operating system?
