Yesterday, I installed Windows 7(64bit). After downloading Fedora 20 (64bit), I tried to install it by bootable usb. I made the customization in this way:

/boot 2GB


/swap 2GB

By finishing the installation, I restarted my Asus K451LB and I had no option for Fedora, it directly loads Windows 7. I tried to turn off Secure boot but I found no way in Boot page. Then I tried another time with " /boot/efi " but it has the same result too.

Please help me to conquer this problem.

Grub loader automatically used as a bootloader, if you install Fedora AFTER windows. Were there "windows boot recovery" when windows started? Maybe windows recovery environment rewrited bootloader?

I remember there was a way to update grub by ubuntu live on usb. Is there the same pattern for Fedora? @hedayat OK :)

Yes, there is: Notice that for EFI installations, you might need to also mount /boot/efi/ too before trying to re-install grub.

However, if Windows was directly booted right after Fedora installation (so you've not seen Grub to select Fedora even once after Fedora installation), I'm not sure if that will fix the issue. Anyway, you can try that. If it didn't work, the issue might be related to BIOS/UEFI/MBR/GPT ones (e.g. not creating bios boot partition for MBR in UEFI mode)!

You need to give more details: With what booting firmware did you install Windows 7 [BIOS, Legacy (CSM), UEFI with Secure Boot, UEFI without Secure Boot? I do not think Windows 7 supports UEFI with Secure Boot. Correct me if I'm wrong. Did you install Fedora 20 in the same booting firmware? Is your disk partitioned as MBR or GPT? How did make the bootable USB? If you were trying to install a UEFI Fedora 20 or UEFI Windows 7, some methods to make a bootable USB do not work 100% of the time. Sometimes, if your motherboard firmware is set to booting in both Legacy (CSM) and UEFI, Windows 7 will pick Legacy (CSM) most of the time. And you end with a Legacy (CSM) Windows 7 when you thought you installed it in UEFI.

If you installed both OSs using the same boot firmware settings, GRUB should ...(more)
