**aggsondoc** · 10-07-2010

I have recently purchased iomega 320GB USB 2.0 eGo portable hard drive.I have a PC in office and laptop at home having windows Xp.I want to know whether it is possible to boot directly from external portable hard drive just like i have heard and read people using USB Pen drive for the same purpose.If yes,then please explain what is to be done.Thanks in advance...

Well, you can pretty easily boot from the external drive but you need to put an OS first on it. Incase if you dont have any OS installed on your external drive then you have to make mirror image of C drive where your OS is installed to your external drive by using a tool called Acronis True Image and then go into BIOS and select external drive as the first boot drive.
