If you think it does not mean that - then please enlighten everyone
as to what it means :) :)
Can I create a disk with msdos partitioning scheme,
none of the partitions marked as bootable, and have bios
quickly skip over it to the next device in the boot sequence?
So far it looks like the answer is "no" or "it depends on your BIOS."
Both SeaBIOS and your Dell BIOS, based on what we've seen, will
attempt to use the boot sector of a disk with a valid MBR, even when
the boot sector is all zeros. That's consistent with all of the
documentation I can find. It's possible that other BIOS might skip an
all-zero boot sector, but we don't have any documentation of which
systems behave that way.
However, also based on testing, it seems that if you used GPT for your
partitions, then BIOS would skip over the drive during the boot
process. So, maybe that's a solution? The only reasons I can think
of to use MBR are a) you have an operating system that can't read GPT
and b) you need to boot from the drive under BIOS. I don't think
either of those apply to you.
Since my internal drive is dual boot, I do need to boot an OS that does not
recognize GPT :(
So, if I use GPT, then, bios will skip over it if it comes before the
internal boot disk?
I will test that on a usb disk.
