cannot boot into USB drive - verve - 02-15-2015

I created a USB bootable version of windows & using WintoUSB. The USB hard drive on which I created it has two partitions: the partition on which I installed the system, and a partition for storage.
I booted into the USB installed system successfully several times. But not suddenly I can no longer boot into it. I noticed for a time that partition was not automatically mounting for some reason, though I was able to find it in disk management. Now it is mounting, but I still can't boot from it.

When I try to boot from it I receive this message:

"The boot selection failed because a required device is inaccessible."

All my files are visible in the directory so I'm guessing the system is still there if I can just access it.

What is the fix for this? Thank you.

Maybe there are errors on the partition, we suggest you use the CHKDSK to check and fix the errors first. You can refer to the link:
