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?

The point is that you need to have EFI System Partition. So create one with 512MB. For detailed installation instructions check: Ubuntu 18.04 LTS Minimal Install Guide
