Can you try to create all the partitions through Debian's installer. I have a suspicion that partition type may be wrong for BIOS partition. You have specified ext2 as file system for BIOS grub which may mean Linux partition instead of BIOS grub partition (ef02 BIOS boot). In the end, it wa

I'd expect that Grub won't be able to reliably work with that setup - partition 3 goes past the 2TB mark, so the BIOS won't be able to map it properly. Don't forget, when grub is reading the disk all it can rely on are BIOS calls. Add yourself a small-ish /boot partition first and you may be OK.

Hi Daniel, in case of BIOS and GPT you have to create a partition for second stage of GRUB. If I can remember correctly its size should be less than 50MB. HTH Kind regards Georgi I created it - this is the first partition (the one with bios_grub flag). I did things similarly to the descri

Hello, I am trying to install Debian on a 4TB external HDD. Since I want to boot the HDD (also) on old systems which support only BIOS, and since the HDD is larger than 2TB, I decided to go with GPT partition table and BIOS boot (or, in other words: BIOS/GTP). I partitioned the HDD accordingly (s
