I had to boot my HP Envy into Win8 for the first time in ages this morning. When I did that, it installed some updates including a BIOS update. Once this was all done, once again the GRUB boot menu was gone and it booted straight into Win8. Using the advanced boot manager options in Win8 I managed to get the EFI boot menu up and chose Ferdora 21. It was only after Fedora failed to boot that I realised that this was wrong. Some time ago I had replaced F21 with Centos 7 and the three Centos 7 options were the ones that should be available - plus the Windows 8 boot manager. I have managed to boot into a Centos 7 Live KDE image. In this ran efibootmgr which shows the same thing. I can fix the boot sequence, but that will not get me back the Centos entries. Can anyone suggest how I can do that?
