Title: [HowTo] OPNsense Boot Loader Upgrade Summarized
Post by: nero355 on October 24, 2026, 01:04:33 AM
Dear fellow OPNsense users,

I have written a complete document about the OPNsense Boot Loader Upgrade procedure based on what is already written in many topics here on the forum.
However all the information is extracted mainly from the following two :
- https://forum.opnsense.org/index.php?topic=48145.0
- https://forum.opnsense.org/index.php?topic=52579.0
And a lot of that information came from the posts made by Patrick M. Hausen (https://forum.opnsense.org/index.php?action=profile;u=25076) :)

Instead of just Copy->Pasting everything I have done my best to also explain what you are actually doing during the process and which commands do what exactly or how the partitioning layout looks and things like that...

You can read the whole document at GitHUB : https://github.com/nero355/OPNsense---Boot-Loader-Upgrade-Summarized

Any comments or questions are welcome ofcourse! ;)



I had some weird issue after switching it to Public so I hope that issue won't return, but if it ever does please send me a PM/DM via the forum instead of posting it here in the topic! Thnx!
