Good Day,

You must restore all the drivers and files that resided at the 0-partition (about +30MB of utitlities, files, etc). They assist if you will, the BIOS (ie stores the drivers for the CD's and provides the computer with further instructions) Then Windows is booted from the MBR at the 1-partition. The drivers and files are available from HP/COMPAQ. They are not on the Recovery CD.

cheers
