SURVEY: What's your experience of LL installed in UEFI mode - good, bad or ugly?

[N4RPS]

Hello!

"However, on my Toshiba L55D laptop, I couldn't mount the bios_grub partition I created in the 3.0 installer. It couldn't recognize the partition type."

Four things I can think of that could cause this, usually by installers detecting disk partitioning inconsistencies, and/or NVRAM change permissions, and OEM specific code requirements

1)GUID and MBR on the same disk.
2)Old style Award BIOS 16bit requirements (If you are attempting dual boot legacy options)
3)HD path missing in NVRAM for the new boot loader. (the most likely cause, and common for the base Debian installer)
4)case sensitivity OEM bug

Being a Toshiba there may be an OEM pre-boot overlay called HWsetup which may have to be configured to match the windows boot and EFI systems changes. Just more MS junk redundancy. Also worth noting that Windows computers that have the UEFI but no standard BIOS have separate programs that run the POST tests and setup automatically at system startup so setting up Linux Lite to run by itself, could require obtaining a mobo specific BIOS from the OEM because in some cases the files will disappear without Windows remaining on the drive, or a new flash of the BIOS, via jumper or battery removal may be necessary. I'm not an Ubuntu guy, but check to see if the HD path is there or not before you do anything else. If it isn't you may need to use rEFInd to solve it.

Thank you for your diagnosis. However, with no spare time at the moment to research this further, I'll just keep THAT particular machine on 2.8 for the time being.

Of course, as always, if and when I find a workaround, I'll share it with the community...
