dual boot from external HDD

by hancycle / November 29, 2009 12:04 AM PST

Is it possible to dual boot frm an external USB HDD on a Win 7 platform?
My laptop lost its display and I bought a new desctop PC that came with Win 7.
I have an external usb drive enclosure and plan on mounting the laptop drive in it. This drive has Win XP, programs and my personal data files installed.
What would I have to do to make the machine to dual boot from it?

Sure, if you want to run an OS other than Windows from the external drive. That's no problem, but Windows is designed NOT to be able to do this.

You could probably do it with Windows 3.1, if you could find USB drivers and integrate them into the image. From Win95 on though, forget about it.

No version of Windows does this. Yes there are HACKS but these are not easy and I've never found anyone apply this retroactively or after the fact in your situation.

All the files should be accessible but for each date file you may have to install a new software install on the new machine and import the data file.

If I set the boot order in the bios to boot from USB first, would that bring up XP ?

Help, my PC with Windows 10 won't shut down properly

Since upgrading to Windows 10 my computer won't shut down properly. I use the menu button shutdown and the screen goes blank, but the system does not fully shut down. The only way to get it to shut down is to hold the physical power button down till it shuts down. Any suggestions?
