Aurora R7, long startup with error code "Fixing...."

For my Alienware Aurora R7, I get a really prolonged startup every time I reboot my computer. It stops on the ALIENWARE screen, with the circling dots, and the error message:

"Fixing (\\?\Volume{1d3554a0-a9d4-46f5-bb0a-cc7d1a015e6b}) Stage 2: 33% (835 of 1152); Total: 65% ; ETA: 0:08:42"

It takes around 20 minutes to got through this prolonged startup. The percentages, and the ## of 1152, and ETA of course cycle through slowly. 

Wondering if anyone knows the issue and how I can fix this? Do I need to reinstall the OS, replace my hard drive, etc? If the latter, any recommendations? Thanks in advance!
