I think I`m on to something.

Hurry up, gotta hit the hay

Does your motherboard and USB support booting from an external drive?

You can`t do what you want to do that way. You have to have windows on a dvd, a usb stick, or I even install windows from a sandisc card.

hesam mate it cannot be done You can dual boot the internal drive with say 7 & 8 or 7 & XP - you have to understand you just cannot boot any one of four different Windows OS's from an external drive mate.

Just out of pure curiosity where did you get this idea from?? Did you think it could be possible yourself or did someone tell it could be done ?

If someone told you this then I would be having a very stern word with that person because he or she is either having a laugh or playing you for what it is worth - if you get my drift.

The bottom line is that even if you could put four OS's on one external or the internal HDD and I mean IF then you would have to have all four OS's locked to one motherboard and that in itself is an unrealistic and in my mind an untenable expectation.

OK let me see if I have this right?
You want to copy the install media for several versions of Windows to an external hard drive.
You want that hard drive bootable.
You want a menu displayed so you can select and install one of the Windows versions on the drive.

If that is your intention, let me just tell you that that is no easy feat to accomplish. When you boot from Windows Install media it loads the Preinstallation Environment. A mini OS if like. Each version of Windows loads a different version of PE. Making a simple PE disk is a lot of work, even with good instructions. You're in for a lot of work and you're going to need some skills to pull it off. I'm not even sure I know where to start for a project like that..

Look I think I have missed a point a or two along the way while I have been using computers and yes I am not terribly knowledgeable but never have I come across booting from an external drive - except once and that is when I had cloned my internal drive to an external one using a gadget to the HDD outside the case.
Now with the internal unhooked and I set the BIOS to boot from the outside drive powered up and it booted from that drive.

Now I am thinking that it would be possible to repeat that with other OS's on an internal drive and end up with the four OS''s on that outside HDD. That is the only way my limited grey matter can think of attaining this.

BUT I cannot for the life of me see why one would want to then install that outside drive into the machine and use it for booting any particular OS.
1. How on earth are you going to get it to give you an option for any particular OS on it??
2. The drive would have to be for any practical purposes very large presuming that more than just the OS in the four different partitions is going to be loaded with apps like Office security CC burning software etc etc ad nauseum / ad infinitum.

That is just one scenario and when you take into account that you will have to set the BIOS to boot from the external while you still have an internal drive fitted - or will there be one fitted because if you can boot from the external that means that the machine does not need an internal drive!!

My query is why would anyone want to do this?? I cannot for the life of me see any advantage over just having a dual or in this case a quad boot machine.

Plus what is Microsoft going to make of such a set up when their activation checking system will show up four OS's on the same motherboard, because lets face it they will have to be tied to that motherboard to be usable.

Anyway my post of last night has gone unanswered so I think it may be the time to unsub from this thread as it seems to be going nowhere and is in my view teetering on the edge of reality.

@ ICit2lol, The Windows 8, Windows to GO, feature actually does that. It's purpose is to allow an employee to basically take their Windows 8 work setup home with them on a thumb drive or external hard drive and run it on their home PC. instead of taking the whole PC they just plug the thumb drive into another PC and run it from their. Its only available to enterprise customers. It's setup to automatically detect the new and different hardware and activation is not a problem. You can move it from PC to PC to PC too. That being said, that's a special case and your average joe isn't going to do that. It will only work natively with windows 8 Enterprise so if you try it on the regular windows 8 or 7 etc, you will have the issues you described. Activation will likely fail, and any new and different hardware could be an issue. I'm thinking the OP wants to install from the drive though, not run the OS from the drive. I'm still not 100% sure either way though?
