To summarize:
1. You created an USB memory stick on a Apple MAC under the Mojave OS.
2. The resulting USB device does not completely boot on your Lenovo ThinkPadP51, that has MS Windows on it.
The error is:
Code:
open (hd0a:/etc/boot.conf) : Invalid argument
Then both efforts to read
/etc/random.seed and to load the
/bsd kernel fails.
I think something went wrong with writing the install image to the USB stick.
You could try to write the install image to the USB stick for a second time. But now with a
conv=sync added to it:
Code:
$ dd if=install71.img of=/dev/rDISCNAME bs=1m conv=sync
Why?
MAC OS has most of its utilities from FreeBSD. And the
conv=sync is needed on FreeBSD (see
https://docs.freebsd.org/en/books/ha...bsdinstall-pre )
BTW that section of the FreeBSD handbook has procedures how to write an USB flash drive/memory stick under Windows.
There is no need to format the USB device with MS-DOS FAT32.
The
dd command will copy block by block ignoring anything that was originally on the USB thingy.
If it still does not boot you could try another USB stick, I had two USB sticks gone bad recently
