When I boot, the bios display says it is UEFI. Am I mis-understanding what that means?
Am I mis-using the term?
My /boot directory has only two sub-directories: "grub" and "grub2",
no sub-directory "efi".
Each of the two sub-directories has a file called "grub.cfg". The two files are
identical, except for permissions.
In /etc/fstab, the UUIDs are already correct, based on output by both the blkid command
and the lsblk command (which blkid's man page says I really should use instead).
I tried the grub2-mkconfig command in both sub-directories. Then I rebooted. The new
menu has Fedora, other Fedora options, Windows 7 (on /dev/sda1), and Windows 7 (on
/dev/sda2). Each option appears to boot up correctly, though I did not attempt to
actually log in to a windows account.
Why are there two menu entries for windows? On this system, sda1 is the master boot
record, sda2 is the windows partition.
After signing in to Fedora, I get a crash message saying vmlinuz crashed. I couldn't
catch the whole message. Yet the system does seem to work. What's going on?
