Startup Issues with Dell Inspiron 15 5558 Laptop Running Windows 10

Question

Long story short, I'm hoping someone can help me with a problem I'm having.

My Dell Inspiron 15 5558 Laptop running Windows 10 is stuck in a boot-up loop. I keep getting error code Oxc000000f over and over, way after having followed many suggested troubleshooting steps.

System tests, such as chkdsk and sfc scannow, have indicated there are no problems with the hard drive or anything else. The only error I get when running the Dell built-in diagnostics is a simple warning that my primary battery (34%) is nearly reaching its lifecycle end, but I've received this warning before, and it never stopped my computer from booting up. I've always plugged in my laptop AC adapter when I use it, so my laptop has run on its primary battery very little.

Of all things, I'm now unable to boot into the WinRE or Safe Mode. The only other place I can boot into is the Boot Menu, but attempting to function key my system anywhere else only reboots me back to the Oxc000000f blue screen.

Does anyone know how I can get to WinRE or at least a command prompt??

Many thanks!

If the system still has its original hard drive, it likely needs to be replaced. You can run the extended Dell diagnostics on the drive, or use a utility from the drive's manufacturer -- Seagate, WD or Toshiba, but this drive is on the order of 8 years old, with a design life of 5.
It likely is a good time to replace the drive with a 2.5" SATA SSD.
