Using Parted Magic to resize a partition

Parted Magic can be found here. You will also need to use something like UNetbootin which will install Parted Magic onto a USB or CD. It can be found here.

Once you have Parted Magic installed onto some type of media device (USB / CD) reboot the system you are going to use it on and load from the media. (Either from a boot menu that will automatically pop up or you may have to go into the bios and set it to read USB or CD-ROM first on the next boot, it all depends on your motherboard. Usually pressing one of the following will get you into bios or a boot menu: F12 or Delete)

You should be prompted with a screen like this:
Press Enter or allow it to automatically boot.

For our example we are going to change the 7.5 GB (7,679 MiB) partition down to 4 GB (4096 MiB). Once you enter the desired size press “TAB" as it will auto fill the free space. Now press “Resize/Move".
