How to use Gparted to change portition to NTFS

By default, gparted can't work with NTFS partitiions.
You need to install ntfsprogs to gain NTFS access via gparted.

-Close gparted.
-In terminal, enter:

sudo apt-get install ntfsprogs

Enter your password and press <ENTER>

-Close terminal
-Reopen gparted, and you should now be able to format a partition to NTFS

Also it's going to be tough to do anything to the partition that you are currently booted into. Try booting up a LiveCd session of ubuntu and then you can do what you like to your hard-drive.

When you change the format to fat32 or ntfs then your data will, of course, be wiped out. A better alternative would be to resize the partition down to about 15Gb, or as small as you can without cramping it too much and then create a new partition to put Windows on. I would make the new partition a fat32 partition and then let the Windows installer reformat it to ntfs.

During the Windows install it will also wipe the partition so copying your data onto the Windows side AFTER install is about the best way. Then you can boot into Windows, see how it looks and then wipe the Ubuntu AFTER making sure that Windows works fine on your machine. You can then resize the Windows partition to fill the whole drive.

Note that a typical Windows install does not include any of the fancy programs such as Microsoft Office, Nero Dvd Burner, codecs, decent movie players, photoshop and so on. Each of those must be bought, paid for and installed separately. Also a machine may need specific drivers for different parts of yur hardware and some of these may be awkward to get hold of. Also you'll need to install antivirus, anti-malware, anti-spyware and other security stuff. Finally there's the updates which requires multiple reboots.

Good luck with all this!
