PowerEdge R520 Stuck on Scanning for Devices

While booting, in the loading VMware ESX i, I hit shift and O to edit the boot line and added the word single (I was attempting to follow an online guide on how to reset the root password but edited the boot line rather than a line in the GRUB) and I am unsure if I would be able to restore it using a Linux live CD (I'm not sure how I would go about that)

On the same train of thought, I need to reset the password for 3 other similar devices. Do you happen to know how I might go about doing that? This is of course not the highest priority, but if you happen to know a good way to do this, it would be greatly appreciated.

You would need to change the drop down on the upper right to the correct version of ESXi, then on the lower left drop down set that the Enterprise Solutions, then locate the ISO for your specific ESXi version.

I don't believe the Live CD will help with the issue, you may need the ESXi custom ISO found here. 

As far as the passwords, we are not able to assist in circumventing security functions, features, or logins. 

I see. following the link and searching for esxi I found multiple drivers. Which one should I use? 

And shame about the inability to help with the passwords, but that does make sense.

I am uncertain which version of esxi I am using. Is there a way I can find out? For background as to what I am doing, the company I am working with right now are liquidating for bankruptcy, unfortunately they lost their passwords for their servers, just so you don't think I am trying to steal information. This also means that I can (and need to) wipe all the drives and reset the server completely. If this is easier then finding and repairing the boot sequence that is an option as well.

Thank you

I am willing to download either one. It seems putty would be easier to get, but should I choose one over the other?

Thank you

Do you have access to Putty or vSphere?

This article covers multiple ways of verifying your version. 

Was there nothing following the 6.5.0, such as Update or U? If not I would go with the 6.5 version.

I found the version to be ESXi 6.5.0. From here I am unsure which one to get 

Should I just get the latest version?

All it said was ESX i 6.5.0 (VMKernel Release Build 4887370) so ill go with the 6.5.0 version and let you know how it goes. Should I do this in a boot or in the lifecycle controller? I also want to double check that when I put a .iso on a disk I should format it then put it on there with nothing else, correct? I apologize for my lake of knowledge on the matter but I appreciate your patience.

Hello qwertyuioplark2,

When you burn the ISO you need to burn it as an image. Something like imgburn or the like. You would not just copy over the iso.

See if you are creating your USB correctly so that it is bootable. Test boot it in another system. May burn a DVD and use that instead.

Test any other commercially printed DVD to make sure you can boot.  If you choose the F11 in POST you can select your boot device with the One Shot Boot menu.

Inserting the disk and booting from the bios boot lead to the system sizing up like when I boot from C: booting from UEFI got to the scanning for devices portion before it froze up again.
