When I boot an external HDD (fat32) and click on "Try Ubuntu", the system hangs, it has no cursor and the hard drive is doing nothing, I have no choice than to hard shutdown the laptop.
I have a Windows boot partition on an SSD, maybe it is the problem here? I checked for a "Fast boot" option in the BIOS but it does not exist nor a "Secure boot".
I have an Nvidia GeForce GTX 1050 as a GPU and an Intel HD Graphics 630 integrated video chip.
I tried "Install ubuntu (safe graphics)" in grub and it worked
