Package: debian-installer Severity: important After installation system was not bootable.
During the installation it said that it had detected that I had UEFI booted the installation CD and proposed to make an EFI boot partion which I accepted. However, after installation, Debian wasn't bootable. I tracked the problem down to the fact that even though it said it was installing a UEFI bootable system, the hard drive was still partitioned with an MBR, which is not UEFI boot compatible. There seemed to be no option for selecting/forcing gpt partitioning. Using a rescue cd and converting the MBR to a gpt and then reinstalling grub-uefi solved the problem without having to reinstall the system. It would seem to me that if the installer detects an uefi booted system and is installing an efi boot partition then it should automatically partition with a gpt and not an mbr. -- System Information: Debian Release: 8.3 APT prefers stable APT policy: (500, 'stable') Architecture: amd64 (x86_64) Kernel: Linux 3.16.0-4-amd64 (SMP w/4 CPU cores) Locale: LANG=en_US.utf8, LC_CTYPE=en_US.utf8 (charmap=UTF-8) (ignored: LC_ALL set to en_US.utf8) Shell: /bin/sh linked to /bin/dash Init: systemd (via /run/systemd/system)
