"BBS hotkey"? What's that? I don't see any keys on my keyboard
labelled anything remotely suggesting "BBS".
BIOS Boot Selector/Service
With most "PC" compatible computers it's reported to you on your POST screen at
the same time it reports which key gets you into BIOS/firmware setup. Otherwise
you may need to get into BIOS setup or the computer manual to discover which key
it is, or find it below:
Abit F9
Acer F12 or ESC or F9
ASRock F11
Asus F8
Biostar F9
Dell F12
DFI ESC
eCS F12 or F10
eMachines F10
EVGA F7
Fujitsu ?
Gateway F12 or F10
Gigabyte F12
HP/Compaq F10, F9 or ESC or ESC,F9
Intel F10
Lenovo F12 or F8 or F10
MSI F11
Shuttle ESC or F11 or F7
Toshiba F12
I'm currently using a gift desktop, windows-10.
No "Post" screen when I power up.
No instructions.
The case is "Dell", so next time I power up, I'll try F12.
Once I've received the new hardware, I'll know what you mean.
Thank-you, Felix.
By default, Fedora uses the "btrfs" file system, right?
By default. Default != mandatory. It supports both btrfs and ext4.
By default, Ubuntu uses the "ext4" file system, right?
By default. Default != mandatory. It supports both btrfs and ext4.
Here, too, this is a major part of why I'm doing this thread. With no
install instructions, I don't know how to control which file systems are
used. I don't even know if both distros have to use the same file
system, though my first guess is that they do if they're on the same
desktop.
I partition, format and LABEL in advance of starting any installer. I then only
need to use the partitioning section of the installer to designate which to
mount
where. LABELs can make it easy to keep track of purpose, and substitute for
UUIDs
in fstabs and root= parameters in bootloaders. Most people use whatever
partitioner the installer includes, but I like using the exact same one always
regardless what I'm installing, giving me no surprises or compatibility issues
by
mixing different ones at different times. It's during installation's
partitioning
phase where selection of filesystem type(s) is normally offered, unless the
basic
installation path selected is to use whatever a installer defaults to.

You should be good with the pair Fedora and Ubuntu, though in 24.04 BTRFS is in
a
module rather than a kernel built-in.
My requirements / preferences have changed.
Stay tuned.
