I'm dual-booting Windows 10 and Manjaro 17 and when I installed the latter I forgot to add a swap partition.
Noticed that and tried to create one from GParted but it is returning the following error when I click on 'New':
It is not possible to create more than 4 primary partitions
If you want more partitions you should first create an extended partition. Such a partition can contain other partitions. Because an extended partition is also a primary partition it might be necessary to remove a primary partition first.
/dev/sda1 is the Windows system reserved partition.
/dev/sda2 is the Windows boot partition.
/dev/sda3 is the other NTFS partition I've been using to store stuff.
/dev/sda4 is the Linux partition.
Already shrinked /dev/sda3 by about 8 GB which I want to use as swap.
Not sure how to proceed.
