Howto rescue Fedora 22 LXDE x86_64 system with LUKS with corrupt boot sector?

The PC has Fedora 22 LXDE x86_64 installed from F22 LXDE Live usb-stick. The system was installed with LUKS encryption enabled. Otherwise the installation was automatic by the LXDE Live system install.

Needed to upgrade BIOS. Only way to do it was from Windows. Windows was now installed on extra partition. It overwrote MBR.

After this only Windows 7 boot.

How to rescue the Fedora 22 LXDE system now?

Booting with the install media, F22 LXDE Live-usb stick doesn't seem to have any rescue mode or selection.

Doing just "grub2-install /dev/sda" on the Live-usb system does not rescue the F22 system on the local hard drive. Now when booted from the hard drive: ". error: no such device: 05xxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx. Entering rescue mode... grub rescue>"

I thought the install media, in this case F22 LXDE x86_64 Live usb-stick, would have tools and methods to easily rescue installs. It should have.

The /dev/sda1 has /boot (ext2) the /dev/sda6 has swap and /, but it is with LVM and LUKS-encryption. The system does not use UEFI.
