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 delete the raid an go to 2 separate disk to take advantage of the SSD (involved reinstalling secondary OS).

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 standards name /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 of being able to destroy the raid it if we let the default /dev/sda for grub install of utopic desktop.

At install time we see /dev/mapper/isw_.... /dev/sda /dev/sdb and /dev/sdc, but it is readable,.

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 elsewhere, but at install selction of disks and partitions, it is also a bit confusing as it show txo devices /dev/mapper/isw_.... each with the copy of the partitions (split the raid) plus /dev/sda, /dev/sdb I don't remember, if we saw partitions on the equaly.

I can make some undestructive tests for you (had hard time at making a working install on this machine).

You can find some hardware infos about the config there:
