I recently had issues with installing Ubuntu on my Acer Spin 1 where the installer would simply hang indefinitely during grub installation or some other part of the install. I found a fix where I manually partitioned everything and finally got it to install. After reboot however all I got was a 'No Bootable Device' screen. I looked around and found a fix that includes going into BIOS and selecting the drive in 'UEFI file as trusted for executing' but there's nothing there. I got into 'Try Ubuntu without installing' again and went into GParted and all the drives are present. The drives themselves are in the files and I can browse through them. They just don't appear in BIOS.
So what's going on? I'm relatively new with Linux but I'm personally sick of trying to install this thing but I don't have any other alternatives. Every time I want to use some form of Linux it never runs as smoothly as everyone describes it. Please help me.
Edit: I should mention that the drives/partitions in the Ubuntu trial appear on the task bar with SD card icons. There is no way in hell they're on the USB boot as they are more than 40GB volumes and my USB is only 3.73GB.
