16.04 is installed alongside Windows. I will free space for 16.04 by shrinking the Windows partition. I understand that it is necessary to boot from a CD \ USB and use a tool like partimage to reallocate disk space.
When resizing the 16.04 partition gParted provided a warning:
Moving a partition might cause your operating system to fail to boot
- What can be done before reallocating diskspace (via Gparted) to prevent boot failure?
- After resizing, what tasks must be performed to configure 16.04 to use the added diskspace?
Results include 16.04 indicating in the file manager that there is now 25GB (previously 13GB).
The Windows partition was shrunk with the diskmgmt.msc console.. gParted was used to resize (expand) the Ubuntu partition: originally 13GB.
