Win7 Disk Management cannot extend my C drive partition. Shrink works, but the Extend option is grey and yes I have Admin Privs.
Easeus Partition Manager also will not allow me to extend C drive (also as Admin).

So I think I need a boot disk to make C drive larger.

GParted (http://download.cnet.com/GParted-LiveCD/3000-2094_4-10698802.html) is free, but it does appear complicated to use.

Are there any other freeware programs run as a boot disk?

One member here a while back posted one From Aomei.

Fee version or http://www.extend-partition.com/free-partition-manager.html.

You install it and it allows you to make a bootable CD.

On that site, under Navigation Links / screen shots & theres a user Guide/full manual with screen shots explaining how to do what ever you want including moving free space from one partition to another - theres also videos on "how to do it"

You need free space to expand your C:\ into. That is why the option is greyed out if there isn't any. If you have a D drive abutting the C drive, then you need to move that drive into a free space area. If you dont have a free space area then you need to resize the D drive smaller and move it so that there is free space between the C and D drives.

A bit difficult to explain :)

Terry, I did try reducing the size of D but the option to extend C was still grey. See screenshot here (http://www.imagef1.net.nz/upload/hd_C_D.jpg).

Notice that there is a large amount of Unallocated Space. I have no idea why that is there (I have not used this pc / hd for over a year) but I would like to get rid of it probably by merging it into D. When I tried to reduce D so as to extend C, I did not reboot and allow D partition to shrink - should I have? I am assuming that I could shrink one partition and extend an adjacent one at the same time.

Am I on the right track or have I done this wrong?

Thanks wainuitech - Aomei looks good - will use it if I cannot get Win7 partition tool to work.

A partition mananger should allow you to move the D partition to the right, so that unallocated or free space is now between the two partitions. The C drive will then have room to expand into.

Edit: I don't think the Win 7 disk manager can do this.

There is another way. Clone the D partition/drive to an external drive, then delete it from your harddrive using the Win7 manager. You can then extend the C drive to the size you want. Use the manager to create another D partition and then clone the D partition back from the external drive.

Sounds like a good idea. D partition is data only, no programs, so I guess I could simply copy and paste the entire 200+ Gb onto my other 1T hd, then shift it back. Or would cloning be quicker, better? I have not done Cloning before. [edit] - Actually, D should already be backed up on my other 1T hd (will have to check - I just resurrected this pc yesterday).

Have you checked whether Easus Partition Manager will allow you to move the D partition "to the right" ? If so then your problem is more or less solved, you would just need to extend C.
Easus Disk Copy, freeware, will copy/clone a partition to another drive. http://www.easeus.com/disk-copy/home-edition/ this would be better than trying to copy file by file or folder by folder. There is a limit to what the clipboard can store !

Or use Gparted, http://gparted.sourceforge.net/larry/move/move.htm

For some strange but very nice reason, this time it worked! I was able to move D to the right, and fiddled around so that C is the right size (larger) and there is no unallocated space. I had given up on Easeus, so thanks for prodding to try it again Terry.

:thanks

Yea, Easeus has worked very well for me. You must have clicked all the right things this time!!

The extend volume grayed out in Windows 7 is because the unallocated space is behind the partition which you shrank but not the partition which you want to increase, and you could not move it to the end of the partition you want to extend, therefore, if you want to extend volume by the snap-in disk management, you could only delete the whole partitions which is behind the target partition.
The software Partition Assistant which was recommended by "wainuitech" looks good, and it enable you to move partition. Here I find another tip of this software, you could use the function "Allocate free space" to quick allocate free space from one partition to another. Hope it could help you.
