I have a Dell Inspiron 8600 with no hard drive, i was just wondering if it was possible that i could install an operating system on an external drive and have my laptop run off of that.
I think thats possible, plug her in and try it out. An external hard drive is basically just an internal hard drive, it just has a case and usually uses SATA / USB 2.0.
Just format like you would with any other hard drive. Good luck ;D
