LABEL=/ used by F7 only tells me that it is a partition. I have zero information as to where it is.
While the default's bad, your own names can be much more descriptive.

e.g. A label of "mainboot" for the boot partition on your main drive.

Replaced by "/dev/sda3" tells me exactly where it is.
No it doesn't.  Something like "/dev/hda3" would (the first IDE drive,
third partition).  But "/dev/sda3" requires you to know which drive the
computer considers is the first drive, at the moment.

Well now that is something I did not know. I have been using fdisk to tell me what is going on and if it says /dev/sdf3 I use mount and it mounts /dev/sdf3 as I desired on F7. I got my SATA drive working as /dev/sdf and it seems to be happy. Of course Grub thinks it is /dev/sdb which is a real shock to me.

it's sort of like you refuse to understand.

/dev/sdX or /dev/hdX is a bios designation where:

hda = primary controller master
hdb = primary controller slave
hdc = secondary controller master
hdd = secondary controller slave
hde = first additional controller master
hdf = first additional controller slave
etc.

grub uses physical drives in the order that they are discovered
[hd0] = the first drive
[hd1] = the second drive
etc.

there is no link between the two since the bios designations remain
constant whether there are devices there or not where grub only
considers physically found drives and numbers them as it finds them.

All that you wrote I already know and understand. But the fact that /dev/hdXY is a known quantity but /dev/sdXY is not a known is news to me.

If you can walk through why /dev/sdXY is not known it would help me. Because I thought it is the BIOS that decides which is the first, second, nth hard drive.
