Bug Description

Hi,

I have a MSI GS60E Ghost Pro laptop. It is quite complex:

2 SSD in raid 0 (intel Raid)
1 HDD standard SATA
2 Gpus (intel and nvidia)

I was trying to upgrade my trusty to utopic.

On trusty if I remember well there was no way to have a functionnal intel raid disks. I had to delete the raid an go to 2 separate disks to take advantage of the SSD (involved reinstalling secondary OS used for gaming).

Legacy boot:
On utopic, I can now use it but the name of the device is still strange (don't know if it is expected, but on other scsi harware I had I always had standard names /dev/sdx...):

/dev/mapper/isw_ihbcddegh_SSD, where SSD is the name given at raid creation of the volume.

Despite of this device I still have access to bare device /dev/sda, /dev/sdb, with the added bonus of being able to destroy the raid on it if we let the default /dev/sda for grub install of utopic desktop (destroyed at the end of install).

At install time we see /dev/mapper/isw_.... /dev/sda /dev/sdb and /dev/sdc, but it is readable on legacy installer even if not ideal.

UEFI boot:
If we boot on UEFI, it is more complex, as grub is not able to find the windows bootmanager for unknown reason (maybe not related).

Don't know if I need to put it somewhere else, but at the install selection of disks and partitions, it is also a bit confusing as it show two devices for the raid /dev/mapper/isw_.... each with the copy of the partitions (split the raid) plus bare devices, /dev/sda, /dev/sdb. I don't remember, if I saw partitions on the bare devices equaly.

I can make some undestructive tests for you (had hard time at making a working install on this machine). If really needed, I can switch to work on an other laptop, and go for destructive tests.

You can find some hardware infos about the config there, setup, etc:
