naturally. Looks like the booting area bcdedit etc needs the focus having watched the video. Shame they didn't show it working at the end !

Did you check whether your netbook BIOS let's you boot from a USB attached disk?

Antman, I guess I was asleep on the wheel. Thanks. Getting too old for this stuff.

In that case, you don't want to be researching ways of install Windows TO a USB flash drive...you want instructions on how to install FROM a USB flash drive. This is a common practice now, and is how most people are getting Windows 7 on their netbooks.

You can quickly prepare the drive to boot the installer, so it looks and acts identically to the DVD...except faster.

There are several links on the web how to install from a USB drive. Here is one of them: ( Creating Bootable Vista / Windows 7 USB Flash Drive at Kevin’s Blog ).

I'm not sure how you leapt to that conclusion, as I don't want to install to the SSD on the Netbook but to a removable drive.

Also I said in the OP "I have created a bootable USB flash drive with the Windows 7 install DVD contents on it, so I am in a position to install to the Netbook hosting the USB hard disk." so I've been there, done that.

Meanwhile, back at the matter in hand, I have set up a partition with two VHDs on and imaged both with W7 Ultimate using imagex (as per the video linked above). When connected via USB both of these crash and restart during the OOBE, either on the netbook or on an HP desktop.

Both will however boot if the SATA hard disk is plugged direct into the HP rather than via a USB adaptor. However I didn't want to do that as I thought (corrections welcome) that the initial OOBE would config Windows to match the hardware which ideally I need to be the Netbook not the HP.

On a separate partition I installed W7 Basic with the disk in the HP, which will boot and run from the HP internally. Next step is to see if that will boot via USB as it's been through the OOBE etc ......

and the answer is "NO", when connected via USB the boot process fails and restarts for the three types of install I have - imaged VHD, imaged partition and partition with installed W7 that works when hard disk conected via SATA direct rather than via USB-SATA bridge.

It is as if just as the coloured balls start flying the system resets the USB interface and loses its own boot drive. ISTR reading about this in XP and some hacks to prevent it. Anyone ?

If you read the line I quoted, you'll see where I got that conclusion. It had already been said, and has been know through XP and Vista that it won't run at a usable state, even if you can get it to boot from an external USB drive, so that's a moot point anyway. You're performance will be bad, to the point you'll wonder why you even bothered....assuming you ever get it working anyway.

Progress ! PWBoot.exe snake oil works

After booting to the VHD via a SATA connection and running through the OOBE I ran the PWBoot.exe (Portable Windows Boot ?) "patch" and was then able to replug and boot into Windows via the USB/SATA cable. Progress, at last.

I think PWBoot just applies a number of registry tweaks, which are also documented separately. Next step is to try the manual approach. I can see in the reflection it's just rebooted after setting a paging file, it's still alive.
