Perhaps you've recently been tinkering with the boot order on your system, or inadvertently misconfigured your dual-boot setup - there are lots of reasons that would cause the dreaded 0xc0000225 error screen when booting up your PC. Using the "startup repair" option from the Windows 10 recovery options is unlikely to fix this particular issue.
Thankfully this problem is fixable, although not straightforward - this process is only for users familiar with using command line tools, disk management and are aware of the risks involved!
To begin, you'll need to boot from your Windows 10 DVD/USB, select your language options and then click the "Repair Your Computer" option on the installation screen:
Now select Troubleshoot > Advanced Options > Command Prompt from the series of menus that appear:
Once you're at the command prompt, you'll need to recreate the boot configuration data using the following steps. Type each command (in bold) and then press enter:
You can now close the command prompt and restart your PC. This should solve the issue, however if not then please let us know in the comments thread - there are quite a few complexities involved with this particular error code, but these steps will work in most cases.
If you have problems running the bcdboot tool, it may be that an incorrect partition has been selected. Sometimes volume are not labeled as ESP and require a bit of trial and error.

Once you're at the command prompt, you'll need to recreate the boot configuration data using the following steps. Type each command (in bold) and then press enter:
- diskpart (loads the disk partition tool)
- list volume (show a list of drive volumes)
- select volume X (where X is the number of the EFI system partition, or ESP). The volume may already be labeled as ESP, or it may just be a small FAT32 partition.
- assign letter=Z (assigns the volume to a temporary drive).
- active (marks volume as active)
- exit (returns to command prompt)
- bcdboot C:\windows /s Z: /f UEFI (recreate BCD)
