installer crashed after completing install. Will not install grub2 to a raid0

[matthias urankar]

I have an MSI GT660R laptop, with plenty of resources. I have 2 500 GB hdd that are raided with a raid0, only option available from the raid configuration tool during post. I have not had this issue prior to this re-install of 12.10. I have tried numerous times today to get this fresh copy installed, i even re downloaded the iso and did a unetbootin install to thumb drive.

i have tried boot-repair and i am going to attempt yet another chroot to reinstall grub2. I have have tried different partitions schemes such using /boot and not using /boot. I have yet to have success at fixing this issue. I thin I have one more option and after that I think It's back to windws (total suckage).

Status changed to 'Confirmed' because the bug affects multiple users.

You are using a fake raid array so grub needs to be installed to the array rather than an individual disk. In your case that would be /dev/mapper/isw_cijcagjega_MainVolume.
