LiveGNOME image won't boot from USB drive in UEFI mode
Posted: 2018/01/16 20:41:33
I have downloaded the latest LiveGNOME image "CentOS-7-x86_64-LiveGNOME-1708.iso" and written it to a USB drive using dd on linux, but I cannot get my Lenovo T570 to boot that USB drive in UEFI mode.
If I set the machine's boot mode to UEFI/CSM or Legacy BIOS it boots the USB to the live GNOME desktop, but not in UEFI mode (which leads to the installer demanding a biosboot partition, which I'm trying to avoid). When I change the boot mode to UEFI only with CSM disabled, it skips the USB drive in the boot order and, if I manually trigger the boot device list and explicitly choose the USB drive to boot, it just flickers and goes back to the boot device list without proceeding.
I also tried writing the ISO to the USB drive using Rufus and WIn32 Disk Imager on Windows with the same results. I haven't tried any of the other images because I think I need the live environment to set up what I'm trying to do, which is install CentOS7 as a dual boot option on an existing Win10 machine.
Any ideas? Thanks!
