I have an issue with the installation of ESXi 6.5 on a DELL PowerEdge R440 server on dual SD Card.
I've downloaded the DELL customized iso on this page => Support for PowerEdge R440 | Drivers & Downloads | Dell US
I've created an USB Bootable with this ISO, I can boot on it without issue then the installaiton of ESXi start.
When I strart the installation after choosing the dual SD Card, after 5% I have the error message below :
For information, I don't know if there is any impact, but at the beggining I've made a mistake I've put the ISO file on one of the SD Card instead of USB Stick.
Thanks for your help.
Since you already wrote data to that/those SD card(s), that's probably why ESXi is failing to install. Boot up without the ESXi boot drive attached and wipe those cards clean. Then retry the installer.
