BCD fails after power off

[bjarne]

If I turn off the PSU then BCD fails to initialize and I get a GRUB rescue prompt. So I have to use BOOTICE to install bootloader again. Trying startup repair doesn't appear to work.



Background: I used to dual boot Ubuntu and Win 7 on my HDD and had to use boot-repair a few times to restore GRUB. Then HDD failed and I cloned all contents to SSD apart from linux partition.


Strangely EasyBCD shows an old BCD I used to have and not the current BSD.


I don't understand why BCD would fail on power off. How can I fix BCD properly?

How do you have your dual boot set up.
Through grub bootloader or Windows Boot Manager?
Best practice is non-traditional way.
Win boot manager, pointing to Grub on Linux partition. Win update breaks the grub bootloader on may occasions, I can attest to that being I run Linux and Windows. Since I changed the set up no problems.
Here's a link to Matthew's Video on it.
How to Dual Boot Windows and Linux. ( The Nontraditional way )

My best guess it the old entry is causing conflict with the bootloader & or corruption in the clone from the failed drive.

What have you tried to do to remove the old BCD entry?

I don't. There is no linux partition anymore. It used to be GRUB handling it, then Windows Boot Manager. The only linux on the system is an entry in BCD.

What have you tried to do to remove the old BCD entry?

I tried using EasyBCD but it doesn't edit the correct BCD instead an old one cached/copied somewhere?



I supposed I could use BCDEdit but I'm not too bothered about the entry. It's this hidden GRUB that is causing problems.



Would doing this help?

So I have to use BOOTICE to install bootloader again.

Did you use bootice to rewrite the mbr to NT6 and pbr to Bootmgr?

 

[bjarne]

Just MBR I think.

Just in case, and for others similarly situation.
