Install (Upgrading) ESXi on my server

Robert AndresenBlog, Tutorials Leave a Comment

After a power failure today, my ESXi server didn’t boot. I ran my ESXi installation from an USB-stick and the screen just went to black when trying to boot from it.

As my setup is almost default, the easiest fix is just to re-install it from scratch.

Getting newest available version of ESXi

Look like VMware is still greedy and the current newest version you can download with a «free» license is 6.7 (not 7 which is available).

I downloaded the ISO from this link: (You probably have to register a user, but I already had one from earlier).

Create bootable USB

I downloaded and used Rufus to create the USB boot medium.

In Rufus:

  • Select the target USB-stick (all data on the USB-stick will be deleted)
  • Select the downloaded ESXi ISO-file
  • Select MBR on Partition scheme
  • Click START

Install on server

I’m installing on a USB-stick instead of a disk – So I had to get another empty USB-stick. I plugged both in the server and booted from the bootable USB-stick I created in Rufus.

All of my installation was next-next-next… I used probably 5-10 minutes to install it. When complete I plugged out the bootable USB-stick, changed boot-order in bios and changed to a static IP when it was booted.

Import VM’s

As I already was running an older ESXi on this server, I had to import the old VM’s again.

This was as simple as clicking «Create / Register VM» button and select «Register an existing virtual machine». All I needed to do, was select the old VM’s from the disks.


On bug that I found, was none of my VM’s had a active network selected on the interfaces. When I selected the default network and clicked save, it didn’t store the selected network. I had to add a new network interface, save, then open setting again to delete the other network device.
