Hi all,
You know if you can dual boot with GPT and BIOS disks on the same machine?
/dev/sdb GPT -> Windows 10 /dev/sda BIOS -> Fedora 23 x64
The machine only starts with Windows; not appear the boot menu
GPT is to MBR as UEFI is to BIOS. GPT is a partition scheme. BIOS is a firmware type. So there's no such thing as a BIOS disk. But if I guess that by BIOS you mean sda is an MBR drive, in which case this is not a supportable configuration and you should reinstall Fedora so you get a UEFI based installation, and sda is partitioned using GPT.
Many firmware do have a legacy option in the firmware setup, but you'd have to switch legacy on to boot this particular installation you have of Fedora; and switch it back to boot Windows. That's probably why right now only Windows is booting.
