This further implies that either use > the whole disk (presuming you have only one), or use UFS only (no ZFS) GPT shouldn't be a problem when you use FreeBSD only. In case you want to multi-boot, using GPT tends to introduce more trouble and work(arounds). Allow me to repeat pointing at the following summary of how to properly initialize disks: http://www.wonkity.com/~wblock/docs/html/disksetup.html You will also find suggestions on how to deal with UEFI booting on that page. > 3) Only install from optical media; not USB stick. Problematic for modern devices with no optical media reader. And sometimes, booting from USB DVD drives also doesn't work as intended. > If you have any problems booting FreeBSD, use the installer to set up a > Fixit/Live Shell session and make sure you put Boot Easy to the MBR : > > boot0cfg -B /dev/ada0 # or whatever device corresponds to your disk Only if you want to boot more than one OS. :-) Sidenote: If you want to only use FreeBSD, you can also use the dedicated disk layout (no GPT or MBR at all). Keep in mind this is the "traditional" way of partitioning a disk, whose concepts were introduced before the PC era. Interoperability with Linux or "Windows" is definitely out of scope here. ;-) > One of the best things in FreeBSD is Boot Easy : it makes life so much > sweeter that once you start using it, you will realize that Grub has no > place in the FreeBSD world - except for any Linux installation later > which should put Grub boot record to its system partition, never the MBR. Yes, this is important to remember. -- Polytropon Magdeburg, Germany Happy FreeBSD user since 4.0 Andra moi ennepe, Mousa, ...
