This is my current partition layout:

Screenshot, part of Windows Disk Management

This is the current situation on my hard disk. I have a 25 GB NTFS partition with windows 8 developer preview (drive F) and a 660 GB partition with Windows 7 (my main OS). I have no idea why there's 10 GB of unpartitioned space in the end, but that is easy to deal with via Disk Management in the control panel.

There is a lot of free space on drive C, and I want to take take some of that space to drive F. It's easy to shrink the C partition, but this will leave more space at the right hand side where the unallocated space is which means I won't be able to extend drive F. So is it possible to shrink drive C and move it further to the right on the disk?

I don't mind if the OS that is now running on drive F gets destroyed in the process, I can reinstall it.

you can split/merge adjacent partitions without much risk...if they are not adjacent, it will involve moving data which can be risky.. – tumchaaditya Jun 14 '13 at 9:15

EaseUS Partition manager is a free for home use partition manager. It is really easy and very robust piece of software. AND ITS MADE FOR WINDOWS - So that Windows users can easily use it.

enter image description here

You can also change the partition on the "LEFT" side. It takes a very long time because it has to move all your files and must be done in exclusive mode, this means a reboot and a blue screen, don't Panic, this blue screen is a console application that does all the magic before windows loads up. Just let it run and it will reboot when done. It never failed me :)

This will fix all the boot sector issues - Linux won't, you have to mess around on your own with safe modes and recovery tools; Because Linux GParted just does not apply the appropriate fixes to the Windows partitions :(

I wonder if this tool can resize your main disk ( since you can't unmount it ), or only an external one? – psusi Jun 14 '13 at 15:14
You can. It reboots the PC and does it in offline mode :) Then boots back when its done. Its the freakiest thing to see... – ppumkin Jun 14 '13 at 15:25
@ppumkin This is a very nice tool, and not having to mess around with making bootable disks or USBs makes this tool much easier to use, and earned my upvote. But that's no reason to bash the GParted based answer. AFAICT, it still gets the job done and is thus still a valid answer. – Nicu Stiurca Jan 6 '14 at 0:13
:) I updated the answer a bit. I just meant that GParted does not apply the necessary fixes to the partition is it get resized or shifted. SOmetimes it works sometimes not. This soft always worked for me, just like you said- without boot discs and stuff. – ppumkin Jan 6 '14 at 17:13

You can use GParted (either on the GParted or Ubuntu live CDs) to shrink the partition and move it to the right. You should make a backup of any important data first, and this process will take a very long time. You also will need to use the Windows cd recovery console to run the FIXBOOT command to get the partition booting again after it has been moved.

are you sure this will work with windows 8? cause the actual boot menu that shows up is the windows 8 one. – kyriakos Mar 3 '12 at 23:02
@kyriakos: Windows 8 uses NTFS, so yes, it will work. Moving partitions around does not affect the boot loader. Creating and deleting partition may, however. – surfasb Mar 3 '12 at 23:09
@surfasb, moving windows partitions does affect the boot loader since Microsoft foolishly embeds the absolute start sector of the partition in the boot sector of FAT and NTFS partitions, and the boot loader uses that value instead of what the partition table says. Hence, the need to run FIXBOOT after moving the start of the partition. – psusi Mar 6 '12 at 0:02
@Psusi: Ah yes. It didn't use to be that way. The good ol days. . . – surfasb Mar 6 '12 at 14:27
@surfasb, it has been that way since DOS 1.0. – psusi Mar 6 '12 at 16:35
