I am running XP Pro SP2. I used Norton Ghost to clone my C: drive to an external hard disk, which is connected directly into the computer using USB 2.0 (although Firewire is also an option). I selected this drive for the boot disk in the BIOS, and the boot begins, and is reading the external hard disk (the internal C: drive is disconnected at this time to simulate a failure). It seems to load the boot loader ok, but never loads Windows - instead it just loops back to starting the boot process over and over again. So is it even possible to boot from an external hard disk like this? Or what am I missing? Thanks.

Yes, this is possible, for some computers.

Your computer must have a BIOS that supports booting from USB. You must have made a good image. And your external hard drive must be of the type that will support this also.

A common issue with external USB hard drives is that there is not enough power coming through the USB port to power it up properly. In this case it will work better with an external power supply, if your external hard drive supports this.

I hope this helps getting steered in the right direction to find a solution.

Yes, it's possible to boot from an external drive if your motherboard is configured to allow it.

And, it seems to me that your's is booting just fine.

I suspect that the problem is that you're trying to boot with the settings from your internal hard drive that have been cloned to your external drive. This confuses Windows, so it quits on you.

Are there any boot options presented to you? Like Safe Mode, etc? If so, try Safe Mode and/or see if you can do a repair install of XP on the external drive ( http://www.michaelstevenstech.com/XPrepairinstall.htm ). That might fix it up enough to get it working.

FYI - I believe that it's a violation of the EULA to have 2 copies of XP installed on one system. This might affect your ability to update one or both of the copies.

I'm just wondering why you'd want to boot off the external HD? What advantages would it give you?

I'd imagine that it wouldn't work as fast, since it has to go through the USB to get anywhere. :thumbsup:

To answer some questions... I have an Asus M2N32-SLI Deluxe motherboard and I believe I already tried a safe mode boot too. I am wanting to boot off of external hard disk just as a contingency in case my C: drive ever fails. Thanks.

I should have also mentioned that the Seagate external drive is externally-AC powered. Ghost indicated it had done a successful clone to this drive. Thanks for any additional suggestions anyone can offer.

You might try a repair install of XP (as mentioned previously) and see if you can point it to the USB drive. You may have to disconnect the power to the boot drive to force it to look elsewhere.
