Where is my boot loader? Installing windows 8 from ubuntu

view story

http://askubuntu.com – So I have ubuntu on live USB and I installed Windows 8 via CD. When installation was done, I restarted without the CD (and went into bios and selected option to boot via hard disk), but nothing happens i.e. I have no boot loader, I just have a blinking cursor forever. So I went back into ubuntu via my live USB and tried boot-repair, but that did not fix the problem. Any suggestions? Thanks, (HowTos)
