Hello, Today I tried to do a fresh install of openbsd 7.1. (from usb pendrive). I tried to do a very basic install (accepting the default - without network - with sets from disk) and when getting to the root disk question I used (W)hole disk MBR. Everything went through smoothly, however when rebooting the system the initial boot sequence goes into an endless loop (manufacture logo appearing again and again) - also cannot enter bios setup anymore. Had to remove the ssd, connect via usb and dd with zero the first mb. Tried several things i.e. changing bios options, upgrading bios to latest version, using uefi etc nothing worked. Always same endless boot loop.
After some time I found a work around by installing from the 7.0 installation image and then upgrading to 7.1. Everything works now. Does anyone know why this might be happening? It would seem that changes to fdisk did change the MBR (or how it is written) which at least on my machine - old dell e7240 - is preventing it from booting. Any help is highly appreciated. Thanks, Michael P. S. Not sure if this is a bug and if it should be reported.
