Error: Could not load multiboot modules: Already exists

[JonTheFalcon]

I have tried searching for this error and cannot find any other instance of this error online.

When my computer is booting and starting up ESXi, I get the pink screen with the message: "Could not load multiboot modules: Already exists"

This started after installing a used hard drive into my tower and getting it formatted and ready to be used as another datastore.

I did not assign anything to the new datastore or use the new drive yet, when the drive started clicking.

I shutdown my tower and removed the faulty drive and now I get this error message when I boot it up.

I have a feeling this has to be easily fixed, I just don't know where to start as I'm still new to Vmware.

Let me know if there's any info you need to help troubleshoot.

VMware ESXi 5.5.0

AMD FX-8350 Eight-core processor

16GB Memory

It sounds like the boot image is corrupted.  You could always reinstall ESXi and leave the datastore intact.

I will try that. I will let you know how it goes.

have a look  to sysboot.log and vmkernel.log located in /var/log directory or post it contents...

or collect core dump from host and extract its contents to readable file and attach it to your answer:

VMware KB: Extracting the log file after an ESX or ESXi host fails with a purple screen error

Please post more info about your hardware configuration.

I just received the same exact error.

When I googled it, I found this post which I had forgotten I made back in Sept.

Back then I reinstalled ESXi to get around the error and reconnected to my VMs in the datastore.

This time, I did the exact same thing.

FYI the cause both times was a power outage and the server being shutdown poorly, thereby corrupting the boot image.

Thanks gprentice

I rebooted, did a <Shift+R> at the boot loader screen to revert to the previous image. This rolled me back one update, but the system booted fine and it was much easier to apply a patch than re-install.

Of course you have to have something to revert to, so this won't work on a fresh install.
