sony vaio pcg vx88 install operating system

I have a sony vaio pcg vx88 and I do not have the docking port and i am trying to install a operating system on my hard drive, I do not have a floppy or cd rom, I also have a dell inspiron which i tried to load the ops on first and put it in the sony afterwards but I get the blue screen, any ideas on how to get the op system on the sony, or possible get an external cd rom to work with it. Thanks in advanced for any help.
