I 'm installing Ubuntu with a USB stick in a Windows machine. When creating partitions I can only create / partition and /swap partition. I'm unable create the /home partition from rest free space as it displays as unusable. I know that similar questions have been asked. However as I can see there's only one primary partition and others are logical. Can you please help me to proceed with Ubuntu installation as I fairly new to those things.
/dev/sda free space 105MB /dev/sda1 ntfs 41838 Windows /dev/sda5 ntfs 41943 /dev/sda6 ntfs 52427 /dev/sda7 ntfs 61311 /dev/sda3 ext4 / 14999MB /dev/sda4 swap 4000MB Unusable 33429
