That can be a big problem actually: I'd heard that Windows 7 supported GPT so I recently tried to install it. It turns out that it only supports booting from GPT via an EFI firmware, not using the PMBR and a legacy BIOS. -- Bruce Cran ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "freebsd-questions-unsubscr...@freebsd.org"

Another possible downside: if you want to multi-boot, the other OS may also need to understand both GPT and PMBR. ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "freebsd-questions-unsubscr...@freebsd.org"

That's why we have the Protective MBR that allows a 'legacy' BIOS to boot from GPT. I'm not sure if you can boot past the 2TB point with it though. -- Bruce Cran ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "freebsd-questions-unsubscr...@freebsd.org"

FreeBSD supports installing to and booting from GPT labeled disks that don't suffer from the 2TB size limitation that fdisk imposes. The caveat is that very few systems have a BIOS that can boot from a GPT labeled drive. So regardless of your OS, you may still have issues. It's worth noting that RAID arrays have been larger than 2 TB for years, and the way RAID cards have gotten around the issue is to carve off a chunk of the array and present it to the OS as a small boot LUN. -- Thanks, Josh Paetzel signature.asc Description: This is a digitally signed message part.
