Boot menu not showing up

[Haider134]

I have windows 8 x64 installed on my Laptop. I wanted to install Mac OSX on second partition, so I created iBoot CD and boot my system with it (just for a try, if the CD was working). After running the system with the help of iBoot CD I pulled the CD back to backup all the data first and then format the system. however when I tried to boot from the Windows 8 again. it showed some error and didn't show any Boot screen there. Afraid of loosing my data I installed another windows on another partition, but i am unable to recover or boot from the main operating system. please help me to get back to the primary windows 8 operating system. thank you

You attempted to hack a system (you get no help here on that end).

The easiest way to undo the damage you did is to just reinstall windows properly
