Dell specific and required actions:
Install and boot from an NVMe SSD on a Dell OptiPlex 9020, 7020 or 3020 (tachytelic.net)
EDIT: I see a lot of users using the “dear” word… Im a South Latin European man… and we “men”, only address as “dear” to our wife or mistress, better check your translator… and no “gays” here.
I think the correct words to use in a forum would be “Sir” or “My friend”
No offense taken and no need to reply, good luck.
