Hi,

Has anyone got any idea on what causes Windows Boot Manager black screen errors \Boot\BCD and 0xc000000f ?

Its Windows 7 64bit, home premium edition and it was installed onto a Kingston HyperX 120GB SSD, motherboard is a Gigabye 970A-DS3P.

Trying to use the recovery console wouldn't work, sometimes it would let me get to the command prompt, sometimes it would say there is no Windows install detected and at other times it would say that this was the wrong version of windows. I was using the correct 64bit disk.

Have finally fixed it (for now, i hope), after unplugging my games drives and resetting the BIOS to Optimal Defaults which sets SATA type to NATIVE IDE instead of AHCI. After doing this i was able to get into the console and was able to rebuild the BCD, then was able to fix it using the startup repair option.

Does anyone know what causes it? Is it related to using an SSD with an earlier version of Win7? I do not think mine came with SP1 but am not sure as it was nearly a year ago that i installed it.

I'd really like to stop it ever happening again as it took over 3 hours just to get the recovery console working. Have looked all over for what causes it but can't find a specific cause, anyone have any ideas or information about this?

Thanks in advance.
 
Best way of installing Windows.

Set BIOS/SATA setting to AHCI.

Disconnect all other SSDs/HDDs, put your SSD on the SATA0 port (or whichever is the first SATA-III port).

Install Windows.

Stops problems like this happening.
 
Hmmm the partition Windows installed on probably not set as active or not primary partition and your games drives probably set as active.

Plug in your games drives and open Disk Management to see all drives, C: should set it as primary partition and active.

Just checked mine. D: Raid is set as Primary. C: set as Boot. How do I change C: to Primary?

This would explain why Boot Manager shows as first option in BIOS.

Asus Z97 Pro
C: Plextor M.2
D: Raid
 
Ah I see what was wrong, D: RAID should be logical partition and C: as primary partition.

I googled and found people used free partition manager tools to coverted partitions to types they want without lose data that Windows Disk Management can't do.

Try MiniTool Partition Wizard Home Edition, it very easy and the best tool.
