Comment 72 for bug 1361951

I confirm the issu when trying to install 16.04 LTS from a pendrive.
I chose Something Else and tried to create an ext2 boot partition, an ext4 system partition, a swap partition and a home partition.
It hangs while creating ext2 file system, as described by Eric Brunzell.
Tried for three times, same issue.
Then used GParted to manually create the partitions.
When chose Something Else, I only had to modify the partitions to assign mount points.
This time it worked.
