RX4100 Startup failed 0xC0000225

Hi All,

Last hour my RX4100 just shutdown itself but when I tried to turn on I can’t acces to windows and it said “Windows fail to start” status 0xC0000225 and there’s no phone support in my country. What should I do? I need my data back. Please help.


You can look this over


But you should be able to seek support online


But rx4100 didn’t detech any ext drive. I cant run windows from ext-dvd or flash drive to repair windows. 

Can you tell me step by step please.

Or If you know General Phone Support in any country that can speak thai please tell me because Phone Support in thailand never pick my call since last 3 month until now.

Sorry for my broken english.


You may have to change the boot order in BIOS to boot from USB.

The thumb drive may need to be formatted FAT32 to boot uEFI

You may can recover your data with http://www.diskinternals.com/raid-recovery/

I do not work for WD.  I do not have a phone nuimber but you should be able to contact support through the wd support link I posted before.
