HP Desktop, support UEFI installation, original mechanical hard drive installed Windows 2008, after removing the system disk, re-format as a data disk, but still is the GPT partition.
Add a piece of SSD hard drive.
Start the installation of Windows 2012 with a USB flash drive. (This installation method does not support UEFI, does not support installation to GPT hard disk, only supports installation to MBR hard disk)
After starting the error 0xc0000225, enter after you can start Windows 2012. The problem is, it's so much trouble.
Troubleshooting:
Unplug the old mechanical large hard drive, start a little problem wood has it.
Solution to the problem:
Later found in the machine BIOS, the original BIOS priority to start the UEFI device! Not a traditional MBR hard drive. That is the priority from my old mechanical hard drive to start it ~ ~ ~
OK, BIOS boot sequence inside disable UEFI boot option, fault troubleshooting, Urapidil ~~!!!
