Partition table entries are not in disk order.

Answer 1

sudo apt install ldmtool
sudo ldmtool create all

For persisting the mounted LDM in Ubuntu, create the file /etc/rc.local and copy the code as below.

1. To create the file:

   sudo vim /etc/rc.local
   

2. Content:

   #!/bin/bash
   ldmtool create all
   exit 0
   

3. Make the file executable:

   sudo chmod +x /etc/rc.local
