Topic: Failed to unmount partitions as superuser
I was trying overwrite a Linux distribution on my netbook when I got this error. In the Gparted Live Media, When I right-click on the partition and select unmount I get:
Failed to unmount partition as superuser the installer needs to commit changes to partion tables.
The other options in the context menu are Manage Flags and Information.
I don't know what to do, but I did go to Device > Create Partition Table and got:
1 partition is currently active on device /dev/sda
