i'm lost, i'll explain:
I successfully booted ubuntu from a usb stick on a old macbook pro, I setup disk encryption, account ect...
I then realize that the keyboard doesn't match mine and i setup the password using a "square²" key. I enter a couple commands to download and use the correct keyboard that doesn't include this key I try to take as many measures as i can to be able to enter the password when rebooting so that the change takes affect
Impossible to enter that key..
So I decided best was to reboot from the usb and start all over But i can seem to be able to select the USB from which to boot ubuntu
Please help if anyone can point me in the right direction
