Yes, you have to have at least one sector between partitions for the
chained EBR. I'm curious as to what messed up partitioning tool created
this layout.

Hi,

Assertion (metadata_length > 0) at ../../../libparted/labels/dos.c:2313 in
function add_logical_part_metadata() failed.

As much as I found searching aroud mentioned about partitions needing at least a sector in between eachother for metadata - is that it? Weird thing is that everything worked before I removed my Windows partition from the gap in between sda1 and sda3.
