I have created a 150 gigabyte partition for an extra operating system, but then decided I did not need it. Now I cannot extend my partition C:/Windows8_OS(NTFS), even though the 150 gigabyte partition is unallocated and formatted.

This is a picture of the current partitions.

Screenshot

I am using MiniTool Partition Wizard Free 9.1.

My system:

  • System: Lenovo Y50-70
  • Processor: Intel Core i7-4700HQ
  • Ram: 8GB
  • GPU: Nvidia GeForce GTX 860M
  • Hard Drive: 1TB HDD with a 32GB SSD in the place of the disk drive

When I try to extend the C:/Windows8_OS(NTFS) partition, I get this, even though I have the 150GB unallocated.

Is this a problem with my hard drive, or should I be using a different software?

Thank you,

Wup

    Tried removing the small "Other" partition after the C partition and then growing? Or first try with Windows' own partition resizing tools? – Sami Kuhmonen Sep 22 '15 at 4:36
  • You can't have an unallocated formatted partition... Just saying :-P – Canadian Luke REINSTATE MONICA Sep 22 '15 at 6:32

@SamiKuhmonen has the right idea. Your photo shows a 1MB partition, unknown type, after your C: drive but before the unallocated space. Delete it (which will merge it into the unallocated space, and you should be fine.

Incidentally, Windows has it's own disk management tools. There's a command-line one, diskpart, which is quite powerful. There's also a nice, user-friendly GUI "Disk Management" utility diskmgmt.msc, which is similar to what's shown in your screenshots, but is built into Windows.

  • That worked, I did not know that the partitions had to be next to each other, which is an important piece of information, thanks. – Wup123 Sep 23 '15 at 2:31
  • Yeah, a partition must be contiguous. You can have a logical volume - something that the OS treats as a single drive - that is not contiguous, but actual partitions must be contiguous. You can't expand a partition unless the space next to it is unused. – CBHacking Sep 23 '15 at 5:22
