I have Windows 2008 R2 installed on C:\. From within Windows 2008 R2 I installed Windows 7 RC on external sata drive (mounted as drive E from diskmanagement) . Dual boot works OK.
Then I disconnect first esata and connect a second one (identical, also drive E). I perform same steps as before to install Windows 7 RTM. Dual boot with this drive works OK.
If I now connect to my first esata drive again, dual boot does not work anymore. I get :
Windows Failed to start. A recent hardware ...
I did some research and my guess is that it is the signature of the drive that plays havoc with the BCD.
So here are my questions:
- Is my guess OK
- If so how can I modify the drive signature within the BCD store since I do not see any reference in the BCD elements.
Thanks for your feedback.
