Public bug reported: I am trying to install Ubuntu 14.04 64bit on a slightly old desktop machine.
Booting from USB works fine, the installation runs up to almost the end, but then reports it couldn't install grub into the MBR of my harddisk. My harddisk is a single SSD attached to an nvidia on-board raid controller in JBOD mode. In syslog it tells be something about an "unsupported raid level 255" and "chroot /target grub-install --force "/dev/mapper/nvidia_asdfdfss" failing. Since I used the same installer to install Ubuntu on another machine, I am pretty sure it's okay, and up until I decided to do a fresh install using an SSD, I had a Kubuntu 12.04 running on this machine with the same hardware configuration, except that I had a HDD instead of the SSD, so in principle it should work, somehow. Would be great if somebody has an idea what I could try next. Thanks for your support and let me know if I can be of any further assistance.
