As I told you before, you will have to boot that machine off a cd, dvd, usb
stick. You should therefore select a live distribution (that can be
installed and booted from such a medium) and use that. Be sure to select a
live distro that includes the tools you need. As I told you before, I used
parted magic, but it is not free anymore (even if cheap, and it does provide
all the tools you will need for offline disk maintenance). 
A live Debian, Ubuntu, or any other major distro would probably be ok as
well.  Just choose one you are comfortable with.
E.g. you may try looking at 
http://live.debian.net/
and
https://www.debian.org/CD/live/
for debian live images
