Following the advies of slm, I could destroy the RST raid 0 and create a new raid0 using mdadm using the webpage he gave me. I could start the installation but at the step where grub is installed, I still get an error and installation stop.
When I try to do the step of the webpages below, I get an error while using chroot, telling me that the file or directory doesn't exit despite it does.
Do you have any idea how I can fix this ?
I need to install Mint on my laptop which has a fake raid0. I tried lots of time and always get an error while installing Grub. I checked on the internet and someone found a solution : after installing Mint as usual, I need to chroot into the system installed on raid. The author give the following link to help : https://help.ubuntu.com/community/Grub2/Installing#ChRoot
The fact is that I just can't apply this solution to my computer. I'm stuck at the step 7 where I need to mount the correct partition. When using the partition GUI tools, I can see 4 volumes : the first one has 3 partitions (one efi, one ext4 and one swap). The 3 others volumes seem to be the 3 partitions of the first volume take one by one. Otherwise, it is asked on the link above to use fdisk, blkid.
The fdisk -l command give me the followind information :
Disk /dev/sda: 128.0 GB, 128035676160 bytes Device Boot Start End Blocks Id System /dev/sda1 1 500130303 250065151+ ee GPT Disk /dev/sdb: 128.0 GB, 128035676160 bytes Disk /dev/sdb doesn't contain a valid partition table WARNING: GPT (GUID Partition Table) detected on '/dev/mapper/isw_ecbefbijea_Volume1'!

The blkid command give me this :
/dev/mapper/isw_ecbefbijea_Volume1p1: UUID="BF26-91E7" TYPE="vfat" /dev/mapper/isw_ecbefbijea_Volume1p2: UUID="ac1c5978-7533-46b9-87ac-d28b7b8c5453" TYPE="ext4" /dev/mapper/isw_ecbefbijea_Volume1p3: UUID="8c12d467-0b8d-48db-ad69-96f7a23b4ca3" TYPE="swap" /dev/loop0: TYPE="squashfs" /dev/sda: TYPE="isw_raid_member" /dev/sdb: TYPE="isw_raid_member" /dev/sdc1: LABEL="SANDISK" UUID="4208-38E8" TYPE="vfat"
Can someone help me to fix this problem ?
