Does it scan and then show a Win7 installation to repair as shown here:



or is the windows blank as shown here:

 
Yes it does. So i have a device to view this hard drive in another computer and copy all my files over so i am considering doing this then reinstalling windows 7. The disc that I am borrowing is a genuine one so if i choose the install option when it boots to the disc, can i use the existing product key? alternatively as it is a toshiba, if i press f2 when starting will this reinstall windows?

If it repairs you need to remember to turn on System Restore. Ask for help if needed.

You need to run Malwarebytes in Safe Mode or Windows Defender Offline from boot disk or stick now, before attempting to repair System files.
 
ok i am downloading windows defender now but bear with me as my internet is very slow

Try Malwarebytes in Safe Mode, or one of the other Bootable AV's given. Some of these can also rescue your files, or there is a step for that if necessary.

I would verify this with one bootable AV scan. If clean or you wish to skip this you can move on to the next steps in order. Keep us posted on results.
