I am a system builder working with some new DB75EN boards.
I'm installing Windows 8 Pro 64-bit on these boards.
Specs as follows:
Board: DB75EN AAG39650-303
BIOS: ENB7510H.86A.0045.2013.0307.1509
Processor: i5-3570K
Memory: 8GB Kingston Extreme in slot DIMM1 at 1600MHz (default)
No additional PCI / PCIe devices
Hard Drive: SanDisk SDSSDH2128G
I install Windows 8 Pro 64-bit with Motherboard in UEFI mode (with Legacy disabled).
Windows installs and reboots automatically.
Motherboard repeated reboots forever during post. I have Secure Erased the SSD twice and reinstalled, and set motherboard to defaults except disabling Legacy Boot.
Every time the motherboard repeatedly reboots when UEFI is on and Legacy is off.
I have installed many other INTEL motherboards with Windows 8 Pro 64-bit and UEFI mode with legacy off without issues.
Does anyone have any ideas?
