I am trying to find a simple solution for booting a PC from a USB Flash Drive just for the purpose of copying files off of the internal Hard Drive. I work for a school and sometimes kids come in with systems so screwed up I can't even boot them into safe mode, and for some reason several students choose not to use Google Drive like they are supposed to.
I don't need this solution to be able to do anything other than copy files to another USB drive but I want it to be quick and easy. CLI would be fine. I have tried other solutions but they don't always work well. I tried an Ubuntu live flash drive but it often gives me issues with reading the internal drive because of the improper shut down of Windows. Also, on one computer there was a problem that caused the system to freeze while booted to Ubuntu and it corrupted my Ubuntu, so a read-only drive would be best.
I really wish there was a solution like target disk mode like on a Mac, this makes everything easier. Also, I know I can pull the drive and plug it into another computer, which I often do, but I would rather not do that if it can be avoided. We are a BYOD environment so I do not like opening up the computers, which many models know have PCI Flash storage instead of regular hard drives, and being liable if any damages occur. Or, in which is the case most often, they have something that was already wrong but then try to claim I did it when I opened up the computer.
