I have attempted to format a hard drive (both HDD and SSD) with an OEM installation, for the 1/18, 1/20, and 2/18 ISO images, and none of them work. The last two fail at the partitioning step, with the error, "No root filesystem available"; the first one fails at the configure clock step, stating that it's missing a dependency (can't remember the exact name). After getting this error, no other options are given, other than "Continue" and "Go Back," both of which result in being unable to continue the installation.
Note that this occurs when booting the hard drive, and the installer automatically starts.
I am attempting this on a Librebooted X200 Tablet, and I've been able to install PureOS on this device with a bootable flash drive and the regular ISO, so it's not an intrinsic compatibility issue with PureOS itself.
