After setting up Windows 7 x64 I was asked to verify that SCCM would work for 32-bit aswell.
I started importing drivers to the Boot image and Task Sequence, deployed the Boot image and set up my TS to start with it.
However after pressing F12 the TS would not start. When checking SMSPXE.log I found the following post:
MAC= SMBIOS GUID= > Could not find an available image BootImageID=XXXZZZZZ
After some troubleshooting I found the issue in the Boot image Properties.
Under Data Source make sure to check Deploy this boot image from the PXE service point.
