I was receiving the above message ‘No Boot Action for Device(32123) found.’  on the PXE service point server, in smspxe.log.

The number (32123) is the resource ID of the computer object found at that SCCM site.  The device was in a collection which had an advertisement pointing to a OSD Task sequence with a valid boot image.  I realised that the message is a little misleading.  I deal with a number of boot images and this particular boot image specified in this advertised Operating System Task Sequence was not on the SMSPXE$ share (i.e. not on the distribution point). 

So things to look out for :

• Make sure that the OSD task sequence boot images are on the distribution point
• That the task sequence you are using have a valid boot image, easy to decommision a boot image without updating your OSD task sequence
