As you know, the following values can be changed by using BCDEDIT:
device partition=E:
osdevice partition=E:
But question is that how did BCD name a certain volume (e.g. E: above) and how can it be corrected? Depending on windows installation method, this drive letter can differ for the same partition. Then, is there a document for BCD explaining about this?

The easiest way would be to open a command prompt, either in Automatic Repair, or in WinPE. Assign drive letters to the System partition (e.g. D:) and to the OS/Windows partition assign the letter (C:). Then used BOOTREC to rebuild the BCD store.

Reboot the system and hopefully it should start.
