I have an imac late 2009. osx el capitan 10.11.2 and bootcamp windows 10. They run fine until i installed osx 10.11.3 update. Bootcamp partition won't load. It shows on finder. It shows on alt boot too, but when i select it, i have this screen:
Tried many fixes hier and on other sites, with terminal, windows disc.
anyone can help, thanks in advance.
iMac, OS X El Capitan (10.11.3)
On the OS X side, run BC Assistant, download drivers for your Mac
... and run setup.exe from the Bootcamp folder. If you get stuck at the RealTek driver installation, please see Bootcamp 6.0 driver install interrupted .
Can you look at Can't resize Macintosh HD partition and mount your EFI partition and check if you have a Microsoft directory on your EFI Partition. IT is likely that the BCD is stored in the EFI partition.
Were the following steps executed?
To do this, type the following commands at the Windows RE command prompt:
- bcdedit /export C:\BCD_Backup
- c:
- cd boot
- attrib bcd -s -h -r
- ren c:\boot\bcd bcd.old
- bootrec /RebuildBcd
The notifications from ASC do not always come through properly. Your 2009 Mac does not officially support W10. The BCD file is in your Mac's EFI partition. If it is touched/modified by an OS X update. it can cause Windows to crash. Please use https://support.microsoft.com/en-us/kb/927392 (bootrec.exe) to rebuild your BCD. Make sure your drives are unlocked before you rebuild the BCD.
Thanks for the answer. I have used these commands among many others, but still stuck at this screen. I will use these commands as shown on this support page and will back again. what that mean drivers are unlocked?
Dear Lonet T, i tried the attributes command you mentioned above to make the BCD writable. Then retried the command RebuildBCD, it shows the windows installation detected, the sucess of the operation. But when i boot to bootcamp i had always the same screen.
This is the output of these commands in Terminal:
sudo mkdir -p /Volumes/EFI
sudo mount -t msdos /dev/disk0s1 /Volumes/EFI
ls -lR /Volumes/EFI

You have already done this before...
Dear Lonet T, i tried the attributes command you mentioned above to make the BCD writable.
If you do this on your boot media and not C:, then rebuilding the BCD is on the boot media. This does not address the issue.
1. OSX Safe mode should not be used for repairing Windows BCD.
2. You will need to boot into Windows Safe Mode using Windows Installation media or a USB Installer created by BC Assistant.
3. The attributes command is a Windows command. It can cause problems if used on the OSX side.
Hi. I've done finally with fresh windows 10 install. But i have a problem, the bootcamp application ist not installed on windows. I can't also see the macintosh hd drive in windows explorer. how to fix this please?
I tried many times to unlock the drive as you told me with diskpart, and i got this screen.
But after that, if i try to reinstall windows, it says always that drive is locked.
Has anyone an idea how to fix this? I'm still stuck at this screen.đ
Thanks for the help.đ
Run diskpart.exe in the Windows Recovery Console and ensure that the BCD location is writable. If it is not, your rebuildBCD will fail.
That's right. I tried this command RebuildBCD many times, and it always fail. How to fix this?
Bootcamp error: windows failed to start
