This is Windows 10 enterprise and Windows 8.1 Pro dual boot machine. 24 GB ram was installed but both PC showed only 16 GB available (now I think this looks like a MOBO issue). I searched web and found one suggestion
to clear the “Automatically manage paging file size for all drives” under Performance Options > Advanced tab > Virtual memory.
I did it on Windows 8.1 and rebooted and saw no change. I did that on Windows 10 and rebooted. And from this point on neither window could boot and could not repaired.
I tried all the available options and none is work. Here is the options and results:
To use System Restore, you must specify which Windows installation to restore. Restart this computer, select an operating system, and then select System Restore.
—— no OS in BIOS
Go back to the previous version
We ran into a problem and won’t be able to take you back to the previous version of Windows. Try resetting your PC instead (Troubleshoot > Reset PC).
System Image Recovery
No image is shown.
Startup Repair couldn’t repair your PC. Press “Advanced option” to try other options to repair your PC or “Shut down” to turn PC.
Not enough memory resources are available to process this command.
I do not want to reinstall windows or reset them because of losing software license and huge amount of time to reinstall everything. This is a nightmare in my history of fixing PCs.
