Hi,

It is not intended to be a dual boot installation. Therefore, the PfSense installation must be replaced by open BSD. My question is what I should do with the (U)efi partition, and how I can possibly link open BSD to it. Does anyone have some good suggestions for me?

Hi,

It depends if you want to keep the existing psfsens install or if you want dual boot.

If looking to install beside pfsens, I would beleive that installing OpenBSD along any existing OS should be no different than installing linux or windows along another OS, as you would need to prepare the block device (SDD) by making space if possible (and if you dont have any) for another partition in which you would install OpenBSD. so any documentation (explaining how to shrink existing partitions, create another partion, handle dual boot) that is not necessarily specific to OpenBSD should help. Im not very familiar with how pfsens work and if it did install a bootloader, if not you might need to install one like GRUB and configure it to be able to select between the two OS at startup.

Overall installing dual boot is very tricky and you should be carefull to not wipe your existing data, a backup is advised

    Hi all,

    I'm going to install openBSD on a small PC that currently has
    PfSense on
    it. This PC boots this OS via (U)EFI, and therefore has an EFI
    partition
    on the existing SSD. The current partition table looks like, as
    shown by
    openBSD fdisk:

     0: efiboot0
     1: gptboot0
     2: swap0
     3: zfs0.

    Should I keep the (U)EFI partition? And if so, how do I mount the
    future
    openBSD root partition to this (U)EFI installation? Are there any
    other
    things I should watch out for? I look forward to receiving responses
    from this community. Sincerely, Karel.
