The partition editor, apparently, didn't see the 260MB EFI partition and wanted to create a _second_ EFI partition, in the middle of the disk,right before the rootfs (monted on /), what made little sense to me. I said "no", making the system, for the time being, unbootable.

Otherwise I think you can find the info you need in theuefi(8) man page. AFAIR it pretty much amounts to "somehow"mount_msdosfs-mounting the EFI partition and copying /boot/boot1.efifrom the FreeBSD installation to /EFI/BOOT/BOOTX64.EFI(case-independent I believe, I actually have /EFI/Boot/bootx64.efi).Should be doable from either of the or (if present)choices in the installer. > > --Per Hedeland > > > Good night, > > I'd like to be able to dual-boot for the time being - multi-boot, at the end of the day. The live CD is certainly my friend, I am just not sure how I am supposed to do it. Should I install some UEFI shell/utility/... in the EFI nvd0p1 partition in order to manage the FreeBSD and Windows booting code, then install/point to the actual FreeBSD (and Windows) booting code (not /boot/boot1.efi, I suppose) ? Has anybody done anything like that? > > In the past, I had used some pay$$ware on BIOS (not EFI) machines, sure, but I'd like to be able to do everything - except for the necessary evil, the M$ Windows OS and some of its $program$ - open-source minded. > > Thanks for any help, pointer, suggestion. Good morning, the solution seems to be trivial: 1) Boot from FreeBSD live CD 2) Mount_msdosfs the GPT EFI partition (e.g. on /mnt) 3) copy (cp -i) /boot/boo1.efi from the live CD to the EFI partition, to e.g. /mnt/EFI/Boot 4) Reboot the machine, access UEFI and create the FreeBSD entry - e.g. path /EFI/Boot/boot1.efi YMMV and at boot time, pressing the appropriate key (e.g. Esc) lets you select which OS to boot. Googling has brought me a number of long and complicated discussions and recipes on various system configurations and some confusion as well; reading _1_ minute the relevant UEFI(8) man page has brought me the solution (!). Shame on me... Maybe someone with docs commit access could put or rather rewrite this "solution" somewhere in the documentation (/FAQs?/handbook?/...), with some frills added (/grub/... configuration?). Thanks all the same.
