I looked for a manual on the ASUS P5Q
by R. Proffitt Forum moderator / May 14, 2011 9:10 AM PDT

And came up short.

Remember that Windows will not boot or run from USB without a boatload of changes (see google) and then it will fail because it's a clone of the internal drive. (Many more boatloads of changes to fix that!)

The ONLY external bootable HDDs I know of that don't require all this are connected with SATA or SCSI. And even then Windows XP fails to boot and run without boatloads of changes.

Supply a good link to the P5Q's manual so I can see if there is some USB boot option.

The ASUS boot menu option and the Windows startup option both use F8. If I hit the keys early enough during POST, the ASUS boot menu comes up. If I wait until that point is past, the Windows options will be next in line. Why ASUS chose F8 and not some other key, I don't know. But they did.
