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

Anyone working on this?
I could dig some info from system if there is a person who needs that.

Could you run this script and attach the results?

Hi,
results from bootinfo attached.

[Phillip Susi (psusi)]

You tried to install grub to an individual drive ( /dev/sdd ). Since you are running fakeraid, you must install it to the raid array ( /dev/mapper/nvidia_bcfbcidd ).

[Pekka Hämäläinen (pekka-hamalainen)]

Well - actually I didn't. I specified the /dev/mapper/nvidia_bcfbcidd but installer didn't like that and instead placed installation where-ever it wanted - this time to sdd. I can re-do the installation during weekend to see where it lands this time.

Hi,

Do you want to offer some Information, or are you currently correcting that
Bug?
I have The Problem on two Systems and could offer Logs and so on.

Hi - apparently my problem is more installer and fakeraid related; I've found bug #1063429 which seems exactly the problem I am experiencing. I have attached 2 photos showing how the installations fails. If needed I can dig some data from the system.
