What was done:
Had taken a backup of
dd (sda7 was around 100GB in size).
Formatted the disk.
Used GParted from a LiveUSB to create new partitions, but this time, created
sda7 with 355GB.
Wrote the backup of
sda7 to the newly created partition using
Used grub tools to install grub and be able to boot.
sda7 is showing a grey area (circled in red) which I assume isn't recognized by Ubuntu as writable area.
So once I finish using up the white area in
sda7, I assume I won't be allowed to use more than the 96.2GB shown.
Is there any way I can make the grey area get recognized?
