I am trying to install FreeBSD 15

[Rock]

Rock The UEFI pin would come from HP, not from Microsoft - assuming your UEFI requires a pin to properly turn off secure boot.

I disabled "secure boot" at the BIOS after pressing F1. Then booted to the bitlocker menu asking to enter it and printing that I have to login my MS account to find it. I decided to go back and enable "secure boot" because I got error while login to my account in MS from phone.

I may try to disable secure boot and when the bitlocker menu is printed to enter the number from login to my MS account.

If you are dual booting many operating systems the boot order also has to be set by priority.

This is where I get a lot of bugs sometimes at boot time with both HP and Dell BIOS

For now I only boot 1 OS at a time by manually disabling the hard drive not in use with multiple hard drives

I put HD on top of boot order since I installed a HD with FreeBSD14.1. But EUFI does not show it.
