I have a 500 GB HDD in which win 7 is already installed. I am trying to install F21 to it. There is a 20 GB space currenctly unallocated for this.

During the Fedora installation I am repartition the 20GB to the following:

2 GB Swap 500 MB as /boot, and remaining as /

When I click on the 'Done button' I get the follow error in the status bar,

Error checking storage configuration. Click for details or press Done again to continue.

When I click on it to get the detail I get a pop up win with this message:

No valid bootloader target device found. See below for details. For a UEFI installation, you must include an EFI System Partition on a GPT-formatted disk, mounted at /boot/efi.

My BIOS I belive is not a UEFI bios but rather a legacy bios. I even changed the /boot to /boot/efi and yet I get the same error. Can anyone help?

Are you trying to install from a LIVE disk?

To be sure the installer isn't booting in UEFI mode, boot the installation media then look at the output of mount | grep efi in a terminal (the output should be empty if the installer isn't booting in UEFI mode).

Is your HDD formatted as GPT?

My system had fedora installed completely on it earlier. It was then I installed win and partitioned my HDD. Perhaps there are stray GPT system.

@anishjp Yes, I am trying to install using a live USB stick.

@Ahmad Samir I tried mount | grep efi and I get the following output efivarfs on /sys/firmware/efi/efivars type efivarfs (rw,nosuid,nodev,noexec,relatime)
