How to make my un allocated drive visible

[venkatakrishna]

Hi friends,
I can't find one of my drive after i made my system triple boot (windows 7, ubuntu and fedora).

If you see picture there is a drive of 155 GB un allocated. I can't see that drive any where. how can i get back my drive back.

Unallocated means its not formated and unformatted drives don't get a drive letter. Format it and windows will assign it a drive letter.

Amazing how you can do all that but yet not know how to format the unallocated space to make another partition.

As mentioned format it.

It may not let you as you already have 4 primary partitions.

I can't format it. I am getting error it says you can't create another primary partition.

Partitioning

I had already three primary partitions. so i can't create another one.
Is there any other option how to merge this unallocated space to C drive without data loss.

It reports all the other partitions have 100% free space. Nothing on them, yet?

If not, delete them. Expand the C partiton 150GB. then, recrete the other partitions.
You can only extend a partiton if Unallocated is next to it, so if nothing is on the other partitons now is the time to delete and re-size.

From the posted image, it looks like the first two partitions are for win 7, next three partitions are for Linux (Ubuntu and Fedora and Swap) and the unallocated space is the free space.

A hard disk allows only 4 primary partitions and as you have already used them up, you can creat an extended partition and one or more logical drives on the free space using Disk management tool of Windows 7.
