Bug Description
Hello,
I'm trying to install Ubuntu 12.04 64bit on Sony Vaio Z131A2JL alongside Windows 7.
I've created a partition of free space for Ubuntu on Windows first then created 4 partitions (/boot, /, /home, and swap)
using the Ubuntu installer on /dev/mapper (I saw that tutorials mention /dev/sda but this was not in the option for me).
The installer then failed with an error message
"Unable to install GRUB in /dev/mapper. Executing grub-install /dev/mapper failed. This is a fatal error."
I've tried installing GRUB on the /boot partition specifically but this failed as well.
Please let me know what I can do to have this fixed.
Best Regards,
E.L.
