Unable to determine Booterror on Proxmox | Get Bootlog via ILO?

[RainerZufall_1]

Hello,

I need to switch operating systems. I added another harddrive (SSD) to my server and installed proxmox.

Everything worked fine but it immediatly jumped to the old os in my boot options.

It seems that there is a very short appearance of the error message from proxmox but i can´t figure out how to tell the server to show me this message as it immediatly jumps to secound boot option.

I am unable to find some bios option like "halt on errors" or sth.

I deleted all other boot options but then the message appears and he jumps back to bios post saying "no bootable os found" or sth. like that.

I already searched some kind of startup log in ILO(4) but i am unable to find.

Can you help me?

Physical access to server is available.

greetings

@TVVJ That solution is unlucky not working

This Bios post option is already enabled "halt with a delay". But i still don´t see the proxmox error. I am quite sure it´s a proxmox startup error, but in some way bios can recognize it otherwise it wouldn´t switch to the secondary boot option.

Server is ML 30 Gen 9. Absolutely perfect working with my old OS.

I will try to boot a Live Linux and access the proxmox harddrive externaly to get the syslogs. I was just hoping there is an easier way.

Greetings.
