Installing ESXi 7 on a Intel NUC 10

With all my other hobbies like 3D printing, micro-controllers, and DJ-ing I’m quickly running out of space at home. My kids insist that the house not be used as a man cave, so I’ve ended up with numerous sheds in the garden. I have a beefy lab with four servers totaling 320GB of RAM and couldn’t justify buying into the whole Intel NUC way of life. Now I want to downsize, so I have invested in my first NUC. I cannot afford at £750 a pop to replace all my servers in one go, but the idea is one at a time. I purchased a bare-bones NUC10 core i7 with 64GB of RAM.  I knew I needed at least 2 NICs, so following William Lam’s blog, I purchased a StarTech USB NIC.  


The first step was to install the memory, which was very straight forward. Undo the 4 screws on the bottom of the NUC, and that exposed the motherboard. Just a case of inserting the 2 x 32GB DDR4 memory sticks. I did notice that this NUC can take both SATA and NVMe disks. I needed neither since, in my lab, I always boot ESXi from USB disk.

The next thing I had to do was prepare a custom iso as I’d read on William Lam’s blog to make the StarTech USB NIC work I would have to install the Native USB NIC drivers, which were a FLING.  So I downloaded ESXi-Customiser so I could easily make a new ESXi 7 iso that had the USB driver embedded into it. ESX-Customiser is no longer developed but still work if you hacked the .cmd file to stop it checking for a windows version by adding a REM statement at the beginning:

The idea is you point it as an existing iso file of ESXi and then the driver you want to include in .vib or .zip format press go, and it makes a new iso file for you.

The next step is to use RUFUS to create a bootable USB disk with the ESXi 7 iso on it so you can install it from the USB key. Select the USB key you want to use and select the newly created iso file. Make sure you have “MBR” and “Boot or UEFI” selected. Click start, and Rufus will create the bootable ESXi7 USB key for you.

Now for me, I had another USB disk, which I plan to install ESXi on. I inserted both USB keys into the NUC and powered it on. ESXi 7 started to install, but seconds later, I got a PSOD  with an error saying failed to verify signatures of the following vibs… it was not happy with the USB native driver.

The workaround was to disable Secure Boot in the BIOS, and the install continued on. The next issue I got was the installation couldn’t find the onboard NIC. I have been in this situation tons of times with home lab installs. The issue (from memory) is VMware includes server-grade NIC drivers and not desktop drivers by default. So the Intel NE1000 driver baked into the ESXi iso was for the server version. I had to downgrade the driver with the one found >HERE< . Now the install worked and both NICs could be seen by the newly installed ESXi 7.

The Backup Bible

As the old adage goes: fail to prepare, prepare to fail.


It’s the perfect description for backup, yet to this day so many companies don’t have an adequate backup & disaster strategy in place for when the worst-case scenario happens. Just how well are you protecting your vital data?


The Backup Bible, a free eBook from Altaro, guides you through the stages of preparing for, responding to, and recovering from a substantial data loss event, which can otherwise be disastrous for a company of any size.


This eBook is the first instalment of a 3-part series comprising the complete guide to data protection. It covers how to get started with disaster recovery planning; how to set recovery objectives and loss tolerances; how to translate your business plan into a technically oriented outlook; how to create a customized agenda for obtaining key stakeholder support; and the essentials to setting up a critical backup checklist.


The second and third parts in the series will be released later this year but by downloading the first part, you’ll automatically receive the other eBooks in your inbox as soon as they become available!


Whether you’re just starting to put together a backup and disaster strategy or you want to make sure your current plan is up to scratch, every IT admin needs to read The Backup Bible.

From IT to PPE

Well Friends you may have noticed that I went quiet over the last few months. There is a great reason for that. At the beginning of the Corona outbreak in the UK I turned my attentions to making PPE Face Shields for Nurses, Doctors and Care-workers. Please watch my video story about the whole experience.
