<teasing> For sure GPT is superior in multiple areas such as handling more than 4 partitions. However the relationship with dual booting is not obvious to me. One single partition may be enough for multi-boot, as long as all the OSes can use LVM. </> Now, let's be serious. Before converting the partition table to GPT, was there an EFI system partition (yes, an MBR disk can have an EFI system partition) ? If yes, was that partition mounted on /boot/efi and did it contain /EFI/debian/grubx64.efi ? Whas grub-pc ever installed on that disk ? You can check with dpkg -l, if it was not purged. What are the sub-directories in /boot/grub ? Is there only x86_64-efi or also i386-pc (meaning that the bootloader from grub-pc was once installed) ? What is the boot mode in the BIOS/firmware setup ? Legacy/CSM, native EFI, both/hybrid ? If EFI or hybrid, can you display the firmware boot menu and does it contain EFI boot entries ? When you boot from a Debian installer CD image (on CD or USB), does it boot in BIOS mode (syslinux menu) or EFI mode (GRUB menu) ? -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of "unsubscribe".
