How do I need to deal with UEFI, if indeed I do. I don't want to screw this up.
Since the computer came with Windows 10, it probably has UEFI firmware. Since you have been running 12.3, and don't know anything about UEFI, I'm guessing that 12.3 is installed for legacy booting. So you probably configured the firmware (BIOS) to use legacy booting. If that's what you did, then the easiest would be to continue with legacy booting mode. Use "fdisk -l" on your hard drive. Check whether it has GPT partitioning or legacy MBR partitioning. If it is legacy MBR partitioning, then you probably have 12.3 running with legacy booting. If you want to do a clean fresh install, I would recommend UEFI. If you are doing an upgrade, then continue as you have been doing. A further check. Look in "/boot/grub2". If there is a subdirectory "x86_64-efi", then you are probably using UEFI. If there is a subdirectory "i386-pc" (I may be slightly off in the name), then you are using legacy booting. If it has both, then you have switched in midstream and should go by the one with the newest timestamp (date). Your install media should be bootable with UEFI mode or with Legacy boot mode. Boot the way that you want to run the system, and the installer should take care of the rest. The chances are that your system is currently set for legacy booting, and the install media will boot that way. How to tell: If you boot the install media with legacy booting, then the boot menu screen has notations for function keys along the bottom. If you boot with UEFI, you will get a grub2 style menu and no function key indicators along the bottom. I'm using UEFI booting, except on older computers that don't support it. On a Lenovo, you should be able to hit F12 during boot, and get a BIOS boot menu to select the install media. Possibly, it will give you a UEFI option and a legacy option. Or, possibly, it will only offer one of those. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
