Hello, On a system with 2 HD, 1 SSH (sdb) and 1 standard HD (sda) of 2 TBit I wanted to make a fresh (and basic) installation on sda I created a 15 GB ext4 partition for that purpose. Using the installer (from a USB stick). I selected my partition (sda6) for the system (/) But I get the following message: Your bios-based system needs a special partition to boot from a GPT disk label. To continue please create a 1Mb /biosboot type I do not know really what I should do. There is already a fedora installed on sdb sdb GPT fdisk (gdisk) version 1.0.4 Partition table scan: MBR: protective BSD: not present APM: not present GPT: present Found valid GPT with protective MBR; using GPT.
