Install non-UEFI system from a UEFI USB?
by andrew.46 from LinuxQuestions.org on (#51W9V)
I plan on reloading my -current installation when 15.0 is released, mostly to sweep away the buildup of cruft on my system. However there is an oddity when booting from a USB key. I make the usb key as follows:
Code:dd if=slackware64-current-install-dvd.iso of=/dev/sdc bs=512 status=progressBut when I boot from this key I can only successfully boot from the first USB option:
Code:UEFI: USB 2.0 Flash Disk 8.07 <-------- This one
SSD 1 ....
SSD 2....
USB 2.0 Flash Disk 8.07 <------- But not this oneThis successfully boots following a Grub menu and I can then enter the setup menu. Now I want to install Lilo to MBR (legacy boot) without setting up EFI at all, is this possible from here on forward? I am keen to learn this before I nuke my system for the reinstall :).
The installer gives a big fat warning:
Code:No EFI System Partition selected
You will need to ..... (details given for setting up UEFI)Which is my main concern...
