Hello @Phizilion and welcome 
Unfortunately the normal installer calamares cannot handle such a partitioning. You need to switch to AHCI at the UEFI Settings, wipe the SSD and reinstall everything without fakeRAID or LDM.
If you need RAID support, then have a look at
- LVM (similar to Windows LDM)
- MDADM (like fakeRAID, but not firmware assisted, in fact only the chunk sync is part of the firmware)
However it possible to use fakeRaid here for installation, but then you need to do a manual Installation.
