Is there anyway to create my own keys to sign the bootloader and make use of the secure boot feature in user respecting way? How to install (for tl;dr users): You need to: 1. setup BIOS/UEFI on legacy mode; 2. start debian installer on expert mode in order to be able to 3. create a GUID Partition Table (gpt), using partman and moving away from the default msdos partition scheme; 4. create TWO partitions right at the begging of the disk: 4.1. the first with 1Mib must be left unformatted and flagged as Reserved space for boot (my understanding is that this area is used to guaranteed that in the end, when grub is installed to MBR, it does not overwrite our GPT scheme); 4.2. the other one must be formatted as FAT32 filesystem and needs to be greater than 32MB (? I failed when I tried to create a fat32 with smaller sizes - 1MB and 10MB, but this 32 is just a wild guess, my successful attempt was with 64MB). This partition will be used to store the bootloader and should be mounted as /boot/efi. 5. from here on you can proceed and install as would normally do. You may safely install grub to MBR at the end of the procedure. 6. Boot the system still in Legacy mode then install the package grub-efi-amd64 (apt-get install grub-efi-amd64); 7. run # grub-install /dev/sda (this will fail, since you are not on efi enabled mode) 8. run # cp /boot/efi/efi/debian/grubx64.efi /boot/efi/efi/boot/bootx64.efi 9. run again # grub-install /dev/sda 10. Reboot and see if your UEFI now sees your wheezy OS. That should do it and you can safely set aside Legacy mode. Secure boot won't work. My punkself deleted the vendor keys. -- André N.
