Hi, I cannot claim to understand a word about these things, but my personal impression is that most modern Linux OSs will do that automatically. If UEFI mode is selected in the BIOS when you boot your computer from the installation medium you will have your system installed in UEFI mode...

But I don't found so much documentation on internet concerning how to install ubuntu (or any other distro) in EFI mode and I knew by the past problem with some devices like laptop HP pavillion where I (and collegues too) failed to install ubuntu in dual-boot, does anybody know good documentation on internet? And does anybody experienced such installation with success and on which hardware? Suggestions are welcome Thank you in advance b.rgds - Gilles _______________________________________________ Lilux-info mailing list Lilux-info(a)lilux.lu https://www.lilux.lu/mailman/listinfo/lilux-info
