No Root File System is Defined

Are you installing using Something Else?
- If you haven't I would try - it will allow you to select the and configure the partitions - You need 1 as a root"/" - this is a drop down window within the partitioning window. BUT if no disks are presented but the LiveUSB.... See UEFI


Also depending on disk configuration - it may not be exactly labeled sda... If it uses flash type disk it may be something like /mmpxxx I dont recall the exact. 
If it has multiple disks, it could be sdb


You mention formatting the drive - the entire disk or partition? If Windows is still installed, it can lock the drive (search for disabling fast boot)


Is this a BIOS or UEFI boot Laptop - If UEFI and using the regular LL install the disk may not be seen (most likely you have SecureBoot disabled to see the USB)
- If so, disable UEFI in BIOS = or set to Legacy in order to install LL. OR Download the UEFI LL installer - it will show a prior version but will update fine.
-If you're not sure, download and try the LL UEFI version..


If these don't help right off - we might need additional system info




** Update **
Looks to be UEFI - I would use the LL UEFI

The 1 that worked (RAID) see if Legacy boot is enabled -- UEFI disabled..
