I am newbie on linux system. My laptop is ASPIRE 4752 where definitely is old machine without UEFI, only legacy BIOS.
My current OSes installed are WIN 8.1 and Xubuntu 18.04-instaling after windows, both OS is x64 works find on dual boot, installed on legacy BIOS mode.
When i try to install/upgrade Xubuntu 20 via usb stick, i found this issue windows 8.1 not in list only Xubuntu 18.04
Next i decide to choice something else menu then setup the path of root and home same as xubuntu 18. When i next to install i got warning about EFI partition doesn't exist. warning about EFI partition not exist
So i decide to quit and still keep on Xubuntu 18.04. I assume if Xubuntu 20 have issue with fully legacy BIOS (old BIOS) as i know today all new machine have dual BIOS.
Because when install Xubuntu 16 18 alongside windows, i didn't meet this situation, Windows 8.1 show in list. Only lost windows boot loader but can fix it by fixmbr on windows, next update grub on xubuntu.
Please help how to install/upgrade xubuntu 20 alongside windows 8.1 with legacy BIOS mode on ASPIRE 4752 via usb stick.
