Windows in external HD - Possible with Linux help

[DouglasCaixeta]

Hi,

I want to install Windows in an external HD (USB) and Linux in my main IDE.

The problem is that my motherboard do not have support for a USB boot. I heard that I can load windows, trough a USB device, even if there is no USB boot support, since Linux will load the USB drives and then load Windows.

How can I do that?
I'm imagining that with GRUB I can choose between Linux and Windows (USB).

I can not say yes or no for sure, but think not.

XP was not programed to boot from a USB hdd , there are some workarounds, read:
