I have a Dell XPS with pre installed Windows 10 and UEFI. I need to install Linux Mint 18 near Windows 10 (I don't want to remove Windows, I need to keep it).
I've already disabled Secure Boot and shrunk Windows partitions to have enough space for linux installation. I have only one physical disk, and have 3 partitions:
C:/ - 48 GB - Windows main partition, D:/ - 10 GB - Windows data partition, E:/ - 50 GB - all for Linux Mint 18
However, my main concern during the install is the GRUB installation point. Let's have a look at an example disk space, as seen by Mint installer (it's not my disk, its only an example from the Internet):
By default, GRUB wants to install in
/dev/sda. However, when I expended the list of Device for boot loader installation: it also showed me other entries:
/dev/sda /dev/sda1 Windows Boot Manager /dev/sda3 /dev/sda5 /dev/sda6 /dev/sda7 /dev/sdb (I install Mint from USB stick, so for sure it's not that option)
Which one should I choose to be able to see GRUB after rebooting (I mean, after installing Mint successfully)? I do not want to mess up with UEFI settings or destroy Windows/EFI partitions and Windows boot manager.
Update: I know I should not use /dev/sda3-/dev/sda7. I only wonder if I should use /dev/sda or /dev/sda1.
