I recently deployed Windows Server 2008R2 on a HP DL380 Gen9 using HP ICSP.
In order to get the server to successfully connect to our PXE appliance i had to disable the onboard 1gb connections, and boot in Legacy BIOS. After a successful deployment i changed the server back to UEFI, however now it wont boot into Windows.
When i try to do a one-time boot with UEFI enabled the Windows Bootloader can be seen. But when selected it just loops me back to the one-time boot menu. And if i let the server boot without interruption it just loops saying there are no bootable devices attached.
When i set the server back to Legacy BIOS it boots into Windows without issues.
Any suggestions?
