Windows 7: Cannot create system repair disk for Posready 7?

Hello all,

I'm trying to created a posready 7 embedded image, and I want to be able to supply a system repair disc and system image with it, should the disk hardware fail for the end user.

The procedure seemed straightforward, and I'm running it straight after a fresh posready install to test it. I have 2 USB DVD drives attached, one to write the image to, and one because it needs the installation media as part of the creation process.

1. from control panel, backup and restore, click Create a System Repair Disc
2. Choose the dvd writer to use to create the disc and insert a blank disc, I choose E: in my case which has a blank DVD-R
3. "Insert Windows Installation Disc", OK I put the Posready7 install DVD in the other DVD drive F: , click continue...
4. System Repair Disc could not be created, The system could not find the path specified (0x8070003)

I have tried inserting instead a Windows 7 Professional DVD at step 3, have tried with a single DVD writer, swapping discs, have tried on a couple of different posready7 installs, one with the 100MB system reserved partition and one without.

I've googled the error code and got lots of results suggesting corrupt user profiles etc, but these are new installs.

Pulling my hair out, anyone else come across this, is it a posready glitch, or am I missing the obvious?

Thanks,
Chris

A followup question to the above. The docs i have seen show that if you press F8 on boot you go to the advanced options and there's an integrated system repair option, above safe mode etc. In my setups I don't get these, with or without the 100MB System reserved partition. Would be nice if that at least was there.

Again its POSready 7, 32 bit; shows in control panel as in 7 embedded SP1.

Thanks,
Chris
