ESXi 8.0 Upgrade – Fatal Error: 10 (Out of Resources)

This is a re-post of information that’s already out there. However, I ran into the error several times and of course more sharing is caring.

I was upgrading my Intel NUC (Canyon Skull) ESXi and came across this error.

Upgrade path:

VMware ESXi 7.03 to 8.0.0.


Out of resources for decompressing data (xxxxxxxxx). gzip extract failed for /tools.t00 (size. xxxxxxxxxxxxxxx) out of resources. 

Error 10 (out of reources) while loading module: /tools.t00

Fatal error: 10 (Out of Resources)


Disable the Thunderbolt device within the BIOS and reboot.


Well documented issue when it comes to trying to install/upgrade ESXi on the Intel NUC’s and using the USB to Ethernet VMware Fling.
