Its is always an issue when you install Windows over Linux or after a Linux installation. The boot-loader record is altered and Windows boots without giving option for Linux.
The default boot-loader for Fedora and most Linux OS is Grub. This is how to fix such problems.
Lets guide you on step-step procedures to fix this matter especially on Fedora/Red Hat but you can also use Fedora Media or DVD this problem for other Linux distribution because Grub works as the default boot loader for all Linux Distributions.
Step 1 – Get Fedora Media
Step 3: Chose Network Option – NO
Step 4: Enter Linux Shell
Step 5: Type this command
Step 6: Change Linux directory
Step 7: Re-install Grub to the first Partition on your drive
Step 8: Reboot or type Exit to go off Shell prompt and restart PC
That should do it. You now have your boot-partion mapped and grub re-installed. After restart it should give you options of selecting between Windows and Linux.
