I have Macbook Pro. I have a portable USB hard drive and I want to install

  • Windows 7
  • Windows XP
  • Ubuntu

on that portable hard drive.

Does anybody know how to install all three operating systems on the drive? I do not want to touch my Mac hard disk or OS X.

This question came from our site for system and network administrators.

bear in mind, even if this is possible, running an OS like Windows over USB would be painfully slow. – tombull89 Jun 17 '11 at 7:35
@tombull89 slow is ok for me. – Rahul Vyas Jun 17 '11 at 8:00
Windows XP will not run on a USB device without some serious hacking. – user3463 Jun 17 '11 at 16:30
For the Linux part, use UNetbootin. It's a dead-simple application to use. You go through the wizard, select the Ubuntu ISO file, select the distribution and the external hard-drive, and you're set. For Windows 7, here is a very detailed howto, but it requires a Windows installation to begin with. I'm not too sure it'll just run on the Mac without any further hacking. – slhck Jun 18 '11 at 15:20
@slhck I don't want bootable windows. I just want to install windows on an external hard drive instead of internal because my internal has mac osx and I don't want to touch it. – Rahul Vyas Jun 18 '11 at 17:04

Your best bet is to defragment and then partition your hard drive.

It's virtually impossible and really impractical to run Windows off an external/flash drive. If it's for programs that do not require much computing power, use VMware or Fusion...
