I have a Lenovo IdeaPad Z570 with most recent BIOS version. I created a USB stick to book Ubuntu from but the IdeaPad does not list/show the stick when I want to select it for booting?
I did try all USB sockets on the machine as well as multiple sequences in the BIOS for booting.
How can I get the notebook to boot from the USB?
PS: the USB stick works fine on a Lenovo Thinkpad T410 and I did update the BIOS as suggested in this question.
