I think you are missing the point.
A STOP error which occurs in safe mode, but does not occur in normal boot...makes no sense.
At least, no sense when reviewing the known causes of BSODs which relate to either O/S functioning or hardware.
Drivers are a frequent cause of BSODS, ususally when the driver has become damaged. When a system boots, various drivers load at various stages of the boot process.
Booting into safe mode...reduces the number of drivers loading.
So...any BSOD which might be due to a driver...is somewhat reduced by booting in safe mode. Windows drivers can still create a BSOD, but the chances of a hardware or software driver creating such...are reduced, if not eliminated.
Since it seems that you have chosen not to quote AUMHA, I will:
Windows lost access to the system partition or boot volume during the startup process. Typical causes: Installing incorrect device drivers when installing or upgrading storage adapter hardware, or a virus."
Since it isn't logical for a boot volume to be "lost" during safe mode boot....yet "found" when booting normally, I suggest that the second noted cause may be applicable.
If it were me, I would run the correct respective hard drive manufacturer's diagnostic on the drive...to satisfy myself that it is without perceived functional problems. Long/extended test.

I don't claim to know what's wrong with your system...I only suggest based on my interpretations of what you have reported thus far.
