Dual-booting Windows 8 and Ubuntu, have boot error 0xC0000098

I had Windows 8 pre-installed on my Asus laptop, and then I installed Ubuntu. I couldn't boot Windows 8 from Grub, but I could enter the bios and set Windows as the first boot device and Windows 8 would boot just fine. I just wanted to have it like this.

I installed EasyBCD nero tool and made a mess. After rebooting with Windows 8 as the first boot device, I got the following screen:

I can boot to Ubuntu but I cant boot Windows 8. I tried automatic repair and fixmbr commands on the command prompt but nothing worked...

Thanks for help

Use the bootrec tool for rebuild bcd. At the prompt command, type the bootrec command as shown below and then press Enter:

bootrec /rebuildbcd
