Public bug reported:
Running the Ubuntu Server installer in UEFI mode fails to install the
Grub bootloader. Attached is the syslog output that shows grub-
installer failed with error code 1. I have seen this on Ubuntu 12.04,
12.10, and 13.04. I believe the problem is that Grub is looking for
device paths that match something like '/dev/sdX' or '/dev/hdX' but the
device I am installing to does not follow that convention.
The reason I believe it is looking for specific devices paths is if,
during installation after my device has been partitioned, I escape into
the shell (using alt+f2) and create a hard link from my device name and
its partitions, to a device name that matches 'sdX', then Grub begins to
install. For example, if my device name is /dev/fioa and has partitions
/dev/fioa1, /dev/fioa2, and /dev/fioa3, I map those partitions to
something like /dev/sdc, /dev/sdc1, /dev/sdc2, and /dev/sdc3 and
continue with the installation onto /dev/sdc. By doing this, Grub will
begin to install on the device.
Possibly useful background information:
- The operating system and all files install just fine without problem,
it is the last step of installing the bootloader that fails.
- In order to have the device recognized during installation, I either
need to run 'insmod' from a terminal or we have to manually modify
initrd to include our .ko file because it is not a standard disk driver.
Using either method does not affect the outcome of Grub2 failing to
install.
- Even though grub begins to install after creating the hard links
mentioned above, it does not finish successfully due to the linked paths
(e.g. /dev/sdc) not being in the device map. That is a separate issue,
but may be expected behavior and would likely need a separate ticket if
it needed to be reported at all.
