There are computers in the classroom where bios is password protected. For my research, I need java on these PCs, but it is not. There is linux on a flash drive with java installed (recorded using UNetbootin)

linux: linuxmint-18.3-cinnamon-64bit on the target PC is the boot "grub2"

I remember once we were told what to choose from it a device and boot from a flash drive, however I forgot how.

1: How to determine what device is a flash drive? For example: root (hd0,5). hd0 is our hard, what will the flash drive look like?

2: How to define a chainloader? chainloader / path / filename There is a fairly detailed instruction on the habre https://geektimes.ru/post/99159/ Here, according to the instructions, I found the isolinux folder, but I don’t have the necessary file.

Actually the question is: There is a flash drive with Linux and Grub2. How to boot?

  • How many computers are in the audience? - Roman C
  • if the task is just to install java on the computer and grub is not messed up, then you can simply add init=/bin/bash to the cmdline ... as a result, when loading, get the root shell (the system will not be initialized), and then you can configure, for example, sudo on besparolny entrance or install java ... - Fat-Zer
  • How to boot? - select your usb device in the boot menu and boot. if it is forbidden in bios (and it is also forbidden to reset the settings), then, as far as I understand, there is no way. - aleksandr barakin 2:55 pm
  • alex, rude moget) roman> about 20 computers - Mikhail Akimov
