I used to be able to access my Ubuntu files on Windows using a piece of software called DiskInternals Linux Reader. This worked fine until yesterday when the partition didn't show up in the software.
I looked in Disk Management and saw that the 25GB Linux partition was now labeled
Healthy (Recovery Partition) and the rest of the drive was now a Simple Volume rather than the Primary Partition.
As well as this, I have two separate Unallocated partitions and I can't seem to remove them. I'm aware that the disk now is Dynamic rather than Basic but I don't know the difference between the two.
