I installed windows 10 on a fresh computer with a single drive. It created 4 partitions (system, c:, hibernation, and recovery).

After freeing up some space on C: and trying to install ubuntu 16.04, the partition space I freed up was "unusable" by ubuntu; looking at other questions on this topic, it seems one cannot have more than 4 partitions on a drive.

My question is, what's the easiest solution? Delete a hibernation partition?

  • Is system an older BIOS system that probably had Windows 7 or newer UEFI based hardware. If newer hardware and if you install Windows in UEFI mode, it uses gpt partitioning and that effectively has no partition limit, but 128 by default. – oldfred May 27 '16 at 13:53

You can have a maximum of 4 primary partitions, but you can have more extended partitions. See the following web page for more info


  • Actually it is only one extended partition that counts as one of the 4 primary partition, but an unlimited number of logical partitions inside the one extended. – oldfred May 27 '16 at 13:51
