After ESXi 5 intall, server does not boot.

Hello all,

After I installed the ESXi 5, I get the following message, after the reboot:

Intel(R) Boot Agent PXE Base Code

CLIENT MAC ADDR: XX XX XX XX XX XX GUID: XXXXXXXXXX

DHCP: (it keeps looking for DHCP for a few seconds)

then stops and

PXE-E53: No boot filename received

PXE-M0F: Exiting Intel Boot Agent.

No bootable device -- insert boot disk and press any key

Any help will be appreciated.

Thanks,

Marcelus
