[BlueOnyx:24316] Re: BO 5209 - not booting, looks like a problem with GRUB

[Fungal Style]

Hi Michael,

A lot of these questions I do not know the answer for as the (original) VM was created quite some time ago and I am working with a copy so that I can do pretty much anything I need to without affecting the live VM.

The problem may have been the steps I took (hen e I listed what I did to get to that point), essentially I just need to make the VM bootable again so I can replicate the steps on the live VM.

I Checked the VM settings, it is set to BIOS and not EFI, hence I mention it may have been the steps I have followed which appeared to work to a degree, then boom, landed me here... back to the same problem with a differing root cause (ie non booting VM but potentially for a differing reason).

So getting back to your comments:
-------------

|   The 5209R ISO is non-EFI as well.

As I mentioned, it may have been my steps taken to remedy the issue that caused the dependency.

No, EFI is not enabled, it is set to BIOS

-------------
|  Is EFI still on for that VM now?
-------------
No, as far I know it was never altered.

So it is VERY possible I followed steps which cause GRUB to want to use it, so maybe going back to the original issue or a BIOS boot optioned VM (non-EFI) not wanting to start, as trying to fix a problem of my own creating after the initial may well be self defeating.

So getting back to the original problem I was trying to fix is:
can’t find command ‘[‘
(then several other similar lines no matter which boot option I choose) 

Regards
Brian

    Hmm. I haven't seen that one yet. Let's see where that is from:

    On none of my 5209R's I have that RPM installed. I wonder why you have

    Is EFI still on for that VM now?
