I used nlite to create a disk for my HP nc8430 , because of having to have the sata drivers for the install. Ive created a handfull of disks and have ran into the problem first of all geting a dw20.exe error, then created another disk, performed a repair install overtop that one and now windows will not update. It did however fix the issue with the dw20.exe. Any ideas, Im at my wits end. ~nayR
