Here is the story:
I have a laptop with a HDD encrypted by Symantec whole disk encryption. I knew that I shouldn't try messing with it with dual boot etc, so I bought an mSATA SSD and installed Windows 7 Professional 64 bit on that. It works perfectly. However, when I tell the boot options to boot from the HDD instead of the SSD, it still boots from the SSD. And when I remove the SSD, the computer naturally tries to boot from the HDD and I receive the error:
Windows failed to start.
The boot selection failed because a required device is inaccessible 0xc000000e
My theory is that the MBR on the HDD has been overwritten and looks for the SSD. And as a result, I cannot boot to my HDD anymore. Is there a way I can re-write the Symantec MBR without decrypting my entire HDD?
