Hi guys!
I'm in a bit of a trouble here. My laptop got bricked after accidentaly installed paragon partition managers boot manager and when I uninstalled I got the massage Windows failed to start.
File: \Boot\BCD
Status: 0xc000000f
F8 is not working either. I got a usb with win 8 on it and I tried to repair startup like 8 times but is also said failed. Restoring to an earlier point doesn't work either on the win8 installler. I need some help, I don't want to reinstall windows.
Thanks in advance!

Yay I just found the solution. I had to boot the pendrive in non uefi mode and startup troubleshoot worked!!!

What did you do with the paragon software? If startup repair can't fix it im not sure what I can do without knowing exactly what you did to cause this, just installing and uninstalling that software should not have done anything. I would say try to boot with safe mode but if f8 does nothing you cant do that, sounds like you may have killed that OS.

I woudl suggest an upgrade to windows 10, but i guess you should have done that while it was free.
If you are literally on W8, not W8.1, making a USB W8.1 stick and doing the upgrade will fix your problem.

I installed something called boot manager.
I have windows 10! I just had a win 8 usb.

Download a fresh copy of windows Media Creation Tool from here: https/www.microsoft.com/en-us/software-download/windows10/
Make a bootable USB drive, boot off it and select upgrade.
