Trouble Booting Linux
Posted: Tue Jun 02, 2020 1:02 am
I am using BootIT UEFI (BIU) and have two operating systems, Windows installed on one SSD, Ubuntu on another separate SSD.
Each SSD has its own EFI System Partition (ESP), and prior to using BIU I selected the operating system to boot through the BIOS.
In BIU I can edit a menu item and it boots Windows fine. But I cannot get it to boot Ubuntu, unless I go to direct boot and then "ubuntu" appears and on selecting that it will boot.
I have looked in the ESP where Windows is, and there is no listing or directory related to Ubuntu. I have tried using the ESP on the SSD where Ubuntu is, but when I try to browse and to find an efi to select, I get a "Unable to mount the filesystem" error message. I have loaded into the menu an item for starting Ubuntu by going to the drives /boot/grub/x86-64-efi/grub.efi or core.efi and both those fail to start Ubuntu.
What are my options here? Is there a way for BIU to read my ubuntu based SSD's EFI System Partition? Alternatively, I could reinstall Ubuntu onto the Windows SSD - but if I install grub to the Windows SSD's ESP, will it destroy my windows boot up?
Thanks.
