My OS is Windows 7.I used EasyBCD for Linux installation as 2 OS. I tried some distributions and when i tried to instal another one instead of normal instalation window i get this.
Can you help me with fixing this problem.
It's been years since I last used Linux, but iirc that indicates that your grub command(s) have a syntax error and grub is kindly giving you the facility to fix it(them) on the fly.
Go back and check your grub menu entries for typos, missing brackets, extraneous or missing spaces etc.
