Don't confuse UEFI and GPT. :-) YOu can use both GPT and MBR (not on the same disk, of course, but on different disks). Choosing MBR is suggested today only for the few cases where it's absolutely needed. Use GPT if you can. You cannot "convert" between the two except via "backup, re-init, restore", which probably is not what you have in mind. But as it is about a new installation of FreeBSD into a multi-OS setting, I'd suggest to leave everything untouched, install FreeBSD on its disk using GPT partitioning, and add a "chain loader" entry to GRUB configuration that boots FreeBSD. GRUB can understand both MBR and GPT, so it doesn't matter. -- Polytropon Magdeburg, Germany Happy FreeBSD user since 4.0 Andra moi ennepe, Mousa, ...
