I want to know if its possible to load another version windows or even Linux if its on external drive and connected via USB ? in windows 8 or was this something that was only possible in windows XP ? if its possible to do this with win 8 , please can someone please explain how to do this ?

I may have the beginning of the procedure, but it may be wrong, I have my external hdd connected to my pc running win 8 via USB, I have gone into start advanced startup and in command prompt.
I can see my external hdd is connected on drive letter F: , this is where xp pro resides, but I can not get it to Load, is there a way ?
On old versions of windows it was possible to load other versions of windows including LINUX that were on a second HDD.

You need to change the bios to allow it to boot to external usb drive first.

To err is human but to really screw things up, you need a computer!

It is my understanding that Windows does not allow installing onto a removable drive (USB, etc), so it must be an internal drive but Linux does not have this limitation.

You have to be a little bit crazy to keep you from going insane.

The only version of Windows that has ever supported installing to an external drive is Windows 8 Enterprise edition. This is not a retail product but available only to large organizations with volume licensing.

Linux should work this way.

You need to distinguish between a second drive (no problem with running Windows from that) and an external drive (can't be done). This is probably because Windows treats a USB drive as removable media. I'm pretty sure that you could run Windows from an external drive connected via eSATA.

There's really no reason why you would want to run Windows from a USB drive. It would be terminally slow, and would only run on the computer you originally installed it on. Much more satisfactory to just get another internal drive, or just a bigger one.

None of these comments apply to Linux, FreeBSD, or Solaris, all of which are quite happy to be installed on, and run from, a USB drive.

It might work, assuming there's some way you can make your external HDD bootable. I do agree with ijack that it would be better for you to use an internal hard drive and install to there.

Alternatively, if you have Windows Vista or newer as your primary OS at this time, you can decrease the size of your hard drive partition (assuming you don't already need that space) and create another partition on your hard drive for purposes of dual booting. That way, you can have more than 1 OS installed on your current hard drive.

1 downside to the latter option, though, is that Linux is real fussy as a dual boot OS and won't work unless you reinstall Windows 1st then install Linux - and yes it HAS to be in that particular order or it won't work either and you'll have just wasted a couple of hours.

If you don't know how to boot a Linux rescue disk and install grub then you may well have wasted a couple of hours. Otherwise you've just wasted a couple of minutes.
