I have Gigabyte 880GM Motherboard that supports Hybrid EFI technology. It has a thin layer of EFI on top of BIOS to enable booting off GPT partition in EFI mode. Earlier I had Windows XP on it in NON-EFI Mode. I have a Hiren Boot CD 15.2 that booted flawlessly then when it was XP.
Now I have Windows 7 64 in EFI Mode with GPT Partition scheme. Now when I try to boot using same CD I get the error
‘No PXE Stack commands (hangup means you have a problematic config’ and nothing further happens. The HDD LED just glows continuously and it never boots.
I thought it might be due to EFI config so I disabled EFI in BIOS and disconnected the HDD from the system. Now it’s just a basic hardware without HDD and NON-EFI boot mode. Still I get the same error.
I wonder where things are going wrong and what could be the next troubleshooting step. The CD is bootable. I crosschecked that by booting my Sony Vaio Windows 7 laptop thru it. The message still appears for a very short moment on laptop but it does not hang there and successfully boots to Hiren Boot CD Menu.
