80070017 Error code, cannot be answered by other threads

Hi

Installed Vista onto my laptop this morning thinking it wouldnt work so i
just did it as a trial run but it worked. Dead chuffed with it, so i decided
to have a sort out and format out my partitions and run it cleanly so it
would be the main operating system. Thats when it would not let me boot from
the dvd i burnt with the iso so i formatted my drives with the xp home cd and
installed that. From then on i have not been able to install vista as i
always get the error code 80070017, which i find puzzling because i had it
working a good couple of hours before. Wondering if there was any explenation
for this. Thanks

Graham
