Hello, I just set up Linux Mint 17.1 on my main PC and then tried to add my Windows 8.1 version for a dual boot setup. I managed to restart from the Windows installation, but when I chose "Windows Boot Manager" in GRUB I encountered error 0xc0000225. I've searched online for solutions but nothing has helped. I've used Bootrec on the installation USB to repair the MBR, tried 'fix boot' and rebuilt the BCD, yet the issue persists. Previously, I could access my 8.1 installation using Super GRUB2 Disk, but now it's not possible without this error. I suspect the problem began when I couldn't install Linux initially, so I wiped my disk using a tool on my live USB called 'Fixparts'. That was the starting point for the trouble. I'm happy to clarify any of what I said if it wasn't too confusing... I'm not very good with words. Thanks all!
I would set up Windows first, then when you connect the Mint, the installer would offer an option to "install alongside Windows" and let you decide how much space you need. The installer would handle the rest.
You're experiencing a problem where GRUB remains installed and neither Bootrec nor FixMBR can fix the issue.
Confirmed the correct drive for bootloader repair. Launch the installation disk, choose your language and keyboard settings. Proceed to Repair Computer > Advanced > Command Prompt. Use DiskPart to select the first disk (select volume 0). Display partition lists on the selected drive. Identify the FAT32 volume and note its number. Select volume 4 as an example. In DiskPart, assign the letter 't' to that volume. Exit DiskPart. Repeat the repair steps for fixing bootloader: cd /d t:\EFI\Microsoft\Boot\bootrec /fixboot. To rebuild the BCD, back up your file first—your current setup may have overwritten it. If you proceed despite this, rename the BCD file to BCD.bk and place it in C:\Windows with the command /l en-us /s t: /f ALL. Be aware that this will affect non-Windows partitions; verify the Windows partition in DiskPart and adjust the letter if needed. Ensure you use the correct locale—US for Australia, AU for UK, DE for Germany—and consider language codes accordingly. After completion, restart the system and remove the installation media.
