Hi Jean-Francois, Newer PC builds and kits might be using UEFI booting protocols instead of the older legacy BIOS protocols; hence, grub2 (ie: not legacy GRUB grub) does have provisions for booting from a UEFI system. This means that you have can either disable the UEFI mode onboard or install a Linux distribution that has the necessary certificates to allow UEFI secure bootup. Disabling UEFI would probably result in problems in booting Windows Bootloader, so it is probably not the best solution in your case, unless you want to go all Linux and legacy boot. There are other workarounds which can defeat the UEFI, but they are very klutzy and do reduce security, so it really would be at your discretion whether you can handle those risks. The best solution is to use a Linux distribution that has the necessary UEFI (SecureBoot) certificates: I believe some flavours of Ubuntu have this and I know that Fedora 23 has it (Does anybody else know of which distros can boot UEFI transparently?) HTH (Hope this helps) Sincerely, Frank
