Some hard disk crashes took me longer than that but here is my 3 step method:
- The Slipstreamer will create a boot CD from an existing Windows installation.
- Update it with Service Pack 3 or look for xpsp3_5512.080413-2113_usa_x86fre_spcd.iso
- Restore any more volumes with Drivesnapshot from any image on an USB drive.
Hopefully you are not reading this too late…
