I have Asus N552VW with the firmwarre mode set to Legacy and the following disks: * 128GB SSD: my windows 10 is installed on it * 2 TB HDD partitioned exactly into two partitions

Knowing that, in the firmware, I have set the boot priority to: Firmware settings

My question becomes: Which device should I use for the boot loader? Ubuntu installation

  • So? Everything hunky-dory? :-)

The Boot Loader goes onto your boot device and as the boot device is your first drive: /dev/sda) that is where the Linux Boot Loader¹ should go.

In your particular firmware, disks are labelled my their disk brand names and as a Liteon is an SSD, that's where the existing OS gets booted from.

In Linux, disks are named /dev/XdY where X can be h or s depending on their controller and Y is a sequential number or letter respectively.

In your particular case /dev/sda and dev/sbd are your disks and dev/sda1 is the first partition on the first disk, /dev/sda2 the second partition on your first disk, /dev/sdb1 the first partition on your second disk, etc...

Note¹: It's called GRUB2 of GRUB for Grand Unified Bootloader.

  • How can I know which device is my boot device?

  • That's an superuser.com question and off-topic here and on AskUbuntu as that has nothing to do with neither Ubuntu, nor Unix and Linux: it depends on your firmware...

  • But this way, the boot loader is on one drive and the Ubuntu is on another drive. Is it OK?

  • I would not tell you to do anything dangerous without warning you. Above is the best I can do with the information I have. If you have more information to divulge, please edit your original question, and then leave a comment here that you did. I might update my answer or delete it depending on the edit.
