Steps to prepare computer:

* So students can't walk over Windows partition once booted into Linux:
1. Remove side (one screw)
2. Unplug SSD hardrive (but leave in case) - its sideways, below GPU, near front.
3. Reattach side.

4. Insert USB drive.

* Make computer boot from USB drives:
5. Switch on computer.
6. Hammer F10 (might be escape, not sure).
7. Hit enter when it complains.
8. You should enter the bios menu - password is H0und012 (0 after capital H. Do not share with anyone!).
9. Advanced -> Bios settings (from memory - might have names slightly wrong):
   - Change timeout to 5 seconds (so you have time to hit F9 below).
   - Disable fast boot (so it actually checks USB drives, rather than skipping straight to Windows).
   - Disable warning beep (it annoys me alright?)
10. Save and reboot.

* Into Linux:
11. When it complains hit enter, then immediately after (within 5 second window set above) hit F9.
12. Select the Sandisk USB drive, legacy boot option. If it doesn't appear reboot - sometimes it's stupid.
13. When Linux has booted cross off the warnings - nobody cares.
