|I am kind of confused. Since you formatted it how did you boot it?|
Are you saying that after you installed the PBX software it now looks for pxe boot? If so the your hard drive is not bootable most likely
Start at bios. See boot options. Managed boot agent is normally a network bootable chip or firmware. There were some add on cards from Intel that also supported managed network boot and admin. Might have to remove that special card.
"Best Practices", Event viewer, host file, perfmon, antivirus, anti-spyware, Live CD's, backups, are in my top 10
