I created an Ubuntu LiveUSB and when I reboot my computer I get no option to boot from it.
I have Secure Boot disabled. There are no fastboot or quickboot options in my BIOS settings.
I have Windows as the lowest on the boot order.
My system boots in UEFI. When I switch it to Legacy, it runs Ubuntu automatically on reboot and I have no option to run Windows.
I formatted my USB with NTFS using Windows' formatting utility.
I created the LiveUSB using the recommended Universal USB Installer.
