Hi everyone,
I succeeded finally to resolve this problem by using a live Kalinux CD, and following this really helpful post How to disable ESXi Passthrough my findings.
Now; I'm asking one question: In aim to avoid this situation in the future, I have 1 raid 5 with 4 SSDs. How can I install ESXi with the ability to, in case of a problem, make a new clean install without affecting existing VMs?
Thank you.
