Long story short, I went for UEFI installation using Rufus without know what UEFI was about a month ago, did some things wrong and ultimately I have EFI records of OSes that no longer exist on my SSD (they show in the BIOS/UEFI firmware screen when pressing F8 after booting the computer).

I'm going for a fresh install of Windows 10, I basically want to make it as close as a brand new PC as possible. From what I've read online, I have to delete my current OS EFI boot record, but I'm not sure if this should be done before fresh installing, or after fresh installing Windows 10.

How can I delete my current OS EFI record, and should this be done right before installing Windows 10 in the disk utility using cmd prompt, or after I have already logged into the new windows install?

I'm going for a fresh install of Windows 10, I basically want to make it as close as a brand new PC as possible.

Just do the following:

  1. Download the current Windows 10 ISO directly from Microsoft by using the Media Creation Tool.

  2. Use this tool to create a bootable USB device.

  3. Within WinPE delete all partitions on the SSD.

  4. Install Windows 10 to the SSD.

  5. When asked for a Windows license key skip that step.

  6. Done

From what I've read online, I have to delete my current OS EFI boot record

The deletion of the EFI partition will accomplish this.

How can I delete my current OS EFI record

The built-in boot configuration data editor can accomplish this. Do NOT use any third-party BCD editor they do more harm then good.
