The ' grub-efi-amd64-signed' package failed to install into / target/. Without the GRUB boot loader, the installed system will not boot.
This is the error I get every time I try to install 18.04. I have formatted the MBR and C drive of Windows and currently I have only dev/sda
to install. I don't want to lose other data which I had in Windows 10.
What should be the status of legacy mode and secure boot while installing Ubuntu 18.04?
I see only dev/sda
instead of dev/sda2
, dev/sda3
.
What should I do?
