ESXi Installation on NUC6i7KYK fails with “Fatal error: 10 (Out of resources)”

When you try to install VMware ESXi 6.0 on the latest Skull Canyon Intel NUC (NUC6i7KYK), the installation fails with one of the following error messages:

Error loading /tools.t00
Compressed MD5: 39916ab4eb3b835daec309b235fcbc3b
Decompressed MD5: 000000000000000000000000000000
Fatal error: 10 (Out of resources)

Error loading /tools.t00

Decompressed MD5: 000000000000000000000000000000
Fatal error: 15 (Not found)

This problem is caused by the Thunderbolt Controller, which is a new component in the NUC6i7KYK, and therefore only the Skull Canyon NUC is affected. The problem can be solved by temporarily disabling the Thunderbolt controller during installation.

To successfully install ESXi 6.0 on the NUC6i7KYK:

  1. Create a bootable USB Installer with Rufus (Howto: Bootable ESXi Installer USB Flash Drive) and plug it into the NUC
  2. Power on the NUC and press F2 to open Intel Visual BIOS
  3. Navigate to Advanced > Devices > Onboard Devices and disable Thunderbolt ControllerNUC6i7KYK-disable-thunderbolt
  4. Install ESXi
  5. Restart the NUC, enter BIOS and re-enable thunderbolt Controller

The NUC works with an unmodified version of ESXi 6.0 Update 2, including:

  • Network Adapter I219-LM (PCI ID: 8086:15b7)
  • NVMe Controller (The NVMe driver, which replaces the AHCI driver are included in the ESXi Image. Packages like xahci are not required)

Additional notes:

  • The SD Slot does not work with ESXi
  • I could not verify the Thunderbolt Port. (Are there any TB v3 devices in the market yet?)
  • If you need additional Network Adapters, the best solution is to use an USB 3.0 NIC with the vghetto-ax88179 driver by William Lam.

We had a nice email discussion in the last week regarding the error, brought together by Raymond Huh. Together with VMware employee William Lam (virtuallyGhetto) and an engineer in the background, Paul Braren (TinkerTry) and Olli Salonen (The NUC Blog). William Lam has also written about the solution with some further recommended BIOS Settings: ESXi on the new Intel NUC Skull Canyon. Very nice to see that we have smart guys that can get unsupported non-enterprise stuff to work on weekends.


  1. I just tried to install ESXi 6.0 U2 on my new Skull Canyon NUC and ran into the same exact issue. This is a BUMMER. I was hoping to use the Thunderbolt controller for connecting a secondary NIC (Apple Thunderbolt-to-GigabitEthernet adapter) using either about-to-be-released Kanex Thunderbolt3-to-Thunderbolt Adapter or Startech Thunderbolt3-to-Thunderbolt adapter.

  2. I see that you re-enabled Thunderbolt 3 in BIOS after you installed ESXi. I will try that as well. When I disabled Thunderbolt 3, ESXi 6.0 U2 installed fine on the Skull Canyon NUC.

  3. Another caveat: I didn’t install any SSDs in the Skull Canyon NUC because I am using iSCSI SAN for all of my datastores. I installed ESXi 6.0 U2 on a 8 GB USB3 flash drive. However, once the ESXi installer completed, and the NUC Skull Canyon rebooted, it could not find any media. It turned out that for some reason, I need to enable UEFI boot, after which ESXi 6.0 U2 booted off the USB flash drive. I tried again to disable UEFI in BIOS, and the bootable media could not be found again. I’m not sure why this is the case, and why the legacy boot is not working with ESXi 6.0 U2. The BIOS I’m running on the Skull Canyon NUC Is KY0034, to which I upgraded from 0033.

  5. I had the exact same problem. Solution worked like a charm. Thank for the solution.

  6. Additional USB NIC for Intel NUCs running ESXi | - pingback on June 21, 2016 at 8:40 pm
  7. I have just installed ESXi 6 U2 on a Skull Canyon but don’t seem to be able to see my two NVMe drives? The only thing I can think that is different to other setups, is that I have used Samsung PM951 drives instead of SM951s?

    Any help will be very much appreciated
