I'm using Windows 8 and I want to partition my hard disk.

My local disk is of 440 GB and in disk management I partitioned the hard disk into local disk E and F from only one local disk C. But my local hard disk C is 221 GB and it is not further partitioned.

Also, it s saying that the available free space for partitioning is only of 110 MB.

So, I want to know how I partition the hard disk and have hard disk C with around 100 GB.

Can you post screenshots of your Disk Utility as it is right now? It's confusing the way you're using drive letters in your description. – Marcus Chan Feb 3 '13 at 2:33
What @MarcusChan means is, post screenshots of your current partition layout as shown by Disk Management. – Karan Feb 3 '13 at 3:07
Sorry again, that's what I meant! @Karan I feel like you're always fixing my mistakes :D – Marcus Chan Feb 3 '13 at 3:41
@MarcusChan: I'm sure you'll do the same for me sometime. :D – Karan Feb 3 '13 at 3:46

I won't be 100% sure until you post a screen shot of your disk management- but it sounds like you are running into an issue that I came across in the past where you can no longer partition the HDD even though you have plenty of available space.

If you are having the same issue I was then your disk management will show your C drive on the right side of the drive. What I learned in this situation is that you cannot extend a drive to the left- only to the right. To fix this I ended up booting into my ubuntu flash drive and using GParted to move my entire C drive to the left side of the disk (this was done with GParted because you cannot move the C drive on the disk while windows is booted). But beware this will break your MBR and you will have to use your windows disc to boot into command prompt and repair the MBR. Here are the commands that will fix your MBR (worked for me in Windows 7 and 8):

/FixBoot. Writes a boot sector onto the system partition to start Windows

/ScanOs. Scans all disks for Windows installations and displays them to you.

/RebuildBcd. Scans all disks for Windows installations and prompts you to pick the ones you want to add to the BCD.

If you want to further partition an exisiting partition, the OS automatically calculates the amount of space that can be utilized to create the partition.

From your message, I assume that you do not have much free space left on your C drive, hence only option is to take a data backup and re-install windows and during installation create the required partition size.
