Figure when I booted with F12 the dell listed the legacy
drive, the cd, and the usb device name. It also had
Fedora listed under UEFI, so I must have selected it, so
it did the UEFI. Don't know how it would be unable to
determine disk configuration? Seems the boot flag on
partition would be a clue, and that it had to create sda3
as a fat16 partition to put the UEFI boot stuff. Then it set
boot flag to sda3, so after it installed, and rebooted, got
a message that legacy boot failed since sda3 did not
have legacy boot info. Had to elect the UEFI boot to load
the Fedora, and then change the boot flag to sda2, and
now system will default boot to Fedora with the UEFI,
but F12 and selecting Legacy will load the Window 10.

Probable true, but my 5 other Fedora machines all use
BIOS, some motherboards don't seem to have UEFI
option. Interestingly, the Dell does, but since its I3 is
only 4th gen and not 8th gen. It can not upgrade to
Windows 11??
Did find an interesting problem still exist between
Windows and Fedora 37 as did with earlier verions.
If boot to windows, and do a warm boot to linux, the
network card will fail to connect. Even warm rebooting
from linux results in same thing. ifconfig down and up
doesn't fix it. Seems windows does something weird to
network card that require a hard boot to clear, or a
process I was able to create for my G4L project that
resets it.
Don't recall where got info to set this to 1, but it works.
#Modified Sept 20 2021 - Windows leaves nic in state that caused dhcpd to fail
#if warm restart after windows load. This resets ethernet devices.
for a in $(lspci | grep -i "ethernet" | cut -f1 -d\ ) ; do
echo 1 > $(find /sys | grep "$a" |grep "reset$") ;
done
# End of reset code

Don't use windows much at all. So probable not worth
doing for me. Windows was pre-install so have no
windows media, and would have to find method to get
the key code.
Do have a HP Laptop - 14-dk1074nr that had Windows
10, but it did upgrade to 11 with no problem. It has a
Ryzen 3 cpu. So, can use it. Might just move Dell to
Fedora only. It also had windows pre installed with no
media provided...
Thanks again to all that gave info..
