Hello, I disabled Intel vPro AMT ME State Control via MEBx. Upon reboot I could not start the OS. Stops with black screen and blinking cursor. I cannot get into MEBx - Ctrl-P not available. I can boot to dos via USB flash drive, but not to Windows via USB or DVD. I tried clearing the CMOS by removing the battery, disable/enable Intel AMT in BIOS, re-flashing the BIOS, removing display adapter and plugging in on board. Nothing works. I can't seem to find any solutions online so far.
Acer Vertion M670G Desktop with Q45 Express chipset, dual boot Windows 10 Preview & Windows 7 Pro.
Any suggestions much appreciated.
