The following steps should be safe to do as it doesn't involve changing anything. Just after a picture. Hope I'm not causing any inconvenience.
1. From a working computer, please download the following:
gparted-live-0.12.1-5.iso
When you have the .ISO file downloaded, you need to create a bootable CD
using a working computer to do that. The .ISO file is a disk image. It should NOT be burned as a regular file. You need a program like
BurnAware Free or
ImgBurn that can burn an .ISO image.
2. Now, please boot off of the newly created GParted CD. See
How to Set BIOS to Boot from CDROM for information on how to boot from the CD.
You should arrive to the following screen:

Press the
ENTER key

By default, "do not touch keymap" is highlighted. Leave this setting alone and press the
ENTER key.

Next, choose your language and press the
ENTER key. English is the default setting [33]

Once again, at this prompt, press the
ENTER key.
You will now be taken to the main GUI screen below
Please
take a picture of this screen (camera or phone pictures will work just fine), and post it here for us to see.
