Where did the > second ada0p8 come from? One of them was created by the Windows installer and the other by the FreeBSD installer. It's not a problem having additional EFI System Partitions (ESP), the UEFI spec allows it (subsection 13.3.3), but it might cause some confusion. Why is the second ESP at 1 GiB? Then again the other one is only at 1 MiB. Maybe the smallest ESP was created by the FreeBSD installer. Whenever dealing with a multi OS setup, first do your research to discover which OS creates which partitions. Install the least cooperating OS first. Make extra copies of the EFI boot loaders for each OS along the way. That's sure handy if you later want to use rEFInd or some other boot manager like GRUB2. I too noticed FreeBSD is in the habit of creating its own ESP, even if one already exists. I felt only one is needed, and I decided to take matters into my own hands when I installed FreeBSD on my laptop, a Dell Latitude E5530 already running Windows 10. I was installing FreeBSD on ZFS, so that's a semi-manual install due to my own preferences on the ZFS FS layout. Depending on the maturity of the UEFI firmware, you can specify your own boot entries in the firmware setup, including one for rEFInd. That way you have multiple options in the future. In the worst case when UEFI isn't mature enough to remember your boot options, you must create boot/efi/nstartup.nsh, a text file containing the absolute pathname of your preferred UEFI boot loader, e.g. rEFInd. The FreeBSD installer might have created a nstartup.nsh file for you. Consider this to be a great opportunity to learn more about UEFI and GPT. I recommend reading Chapter 5 and Section 13.3 in the current UEFI spec, now at version 2.7. You may skim the rest of the spec. http://www.uefi.org/ http://www.uefi.org/specifications http://www.uefi.org/sites/default/files/resources/UEFI_Spec_2_7.pdf > > I do not know what to do from here. gpart set -a actvie ada0 breaks all > > except from booting from the CD. geom=ada0 is the only accepted target for > > set. > > Check out uefi(8) man page. > > Assuming you have refind installed, you should be able to copy > /boot/loader1.efi to your ESP after mounting it.
