How can I boot my PC after my GRUB bootloader was corrupted?

Windows 7 , Fedora 17 , Mageia 2 (before)
Chrome 18

I had 3 operating systems installed – Windows 7 , Fedora 13 and Mageia 2 on my Acer Aspire 4253 laptop. I deleted the partition of Mageia and my GRUB got corrupted. I didn’t have an installation DVD of either Windows 7 or Fedora, so i used Super GRUB 2 from a flash drive everytime to boot my laptop.

Today when I was using Windows 7 , my battery was critically low and laptop got hibernated . When I plugged in the power and restarted the ‘Press F2 ,F12 ‘ prompts were missing and flash drive is not getting detected after POST . What can I do now to boot my PC?
