This is what happened:
- I Boot from the USB by pressing either ESC, F10, F11 when the classmate is starting (The reason I don't know which one is because I pressed them all at the same time..)
- I see windows is not genuine message
- I do step 1 again
- I still get the same message
- I click "activate online"
- I download and run the Microsoft plug in that checks your copy of windows
- It tells me my windows is genuine
- I am happy.
This worked for me and one other team that I know of.
Note: When I was booting from USB, I saw two option, both 'Boot from USB.' I clicked the second one. But basically choose one, if you get an error, then choose the other one and it'll boot.
