UEFI boot consfusion -
by sapolion from LinuxQuestions.org on (#4R6HA)
My machine boots using UEFI but as far as I can tell it boots, or at least makes a first attempt to boot, from the wrong disk. I have an 8 to 10 year old ASUS N76VZ computer, which I bought because it was advertised as having 1TB of disk. It actually had two 500GB disks, When I bring up the BIOS boot menu, both disks seem to have the same name, something like ST123549 - that's just an example because I don't know to look up the actual info without rebooting and going into the BIOS.
I have tried to install and use reFind without luck as it seems to become selectable but then it's not there when the machine starts to boot. I guess because it's on the wrong disk. I believe the actually used bootloader is on sda while linux is on sdb.
I get a list of os's but I think I'm just using the windows boot loader which seems to work, but it also seems to take longer to start booting than it should.
My machine is working and can be booted into Ubuntu or Win10 but the delays and the existence of too many choices make me think I am very very far from having it set up right. Here is the content of /etc/fstab if that would help someone explain to me what I did wrong.
josh@N76VZ:~$ cat /etc/fstab
