View Full Version : BootCamp over USB?

9th December 2007, 01:58 AM
IIRC, Intel Macs can boot over USB, correct? Can they boot non-Mac operating sytems over USB or only OS X? Just wondering...my MacBook has a 120GB HDD, with about 20 or so GB used for a Windows partition. Anyway, I have this mostly empty external USB HDD here, and seeing as though i don't use Windows all that much i'm thinking it'd be good if I could put XP on the external HD, and give that extra 20GB back to the Mac.

Probably a dumb question, i know, but i thought i'd ask anyhoo, someone's gotta know ;)

From what I have read, the software only works with internal disks.

Don't know why they would limit it this way.

windows will not boot install on an external drive. During the boot process windows also stops and starts the usb service, which if the windows drive itself is on a usb drive wil kill the boot process. The only way windows can be used from and external disk is as a virtual machine because the host os controls the usb service.

i haven't done so myself, as it looks a little fiddly:
