Slackware current, inherited laptops, and UEFI
by garpu from LinuxQuestions.org on (#566AW)
So I inherited a Dell laptop (inspiron 15 7559). It had Windows 10 on it, then Ubuntu (18.04, I believe.) I was going to put slackware (current) on it. I made a USB stick from Alien Bob's liveslak (with iso2usb)
This thing will not boot Slackware, unless I turn on legacy BIOS mode. (it does boot Ubuntu without it turned on.) SecureBoot is turned off. Dell weirdness, or? I don't particularly care one way or another, but I'm curious why it won't boot Slackware-current with UEFI on.
I know slackware current and liveslak works fine with UEFI, because that's how I installed Slackware on my desktop. uname -a reports that I'm using 5.4.48, so it's definitely current, and definitely 64-bit.
