Hi,
Followed this excellent guide and it looks like the package was being installed but at the SCCM splash screen the laptop rebooted itself, went back into PXE:
"downloaded WDSNPB
Architecture: x64
The details below show the info relating to the pxe boot request for this computer
pending request ID request: 6
contacting server: 192.168.1.137
TFTP Download: smsboot\x64\abortpxe.com
PXE boot aborted. Booting to next device....."
Appreciate any advice\assistance
thanks!
