Hi I am trying to install Ubuntu on my new laptop, MSI GP62 6QF. It has Windows 10 installed on the 128 GB SSD. Now I want to install Ubuntu on the 1TB HDD. I booted into Ubuntu Live CD using a USB drive. I have choosen the following partitions for installation(I haven't made any change to SSD's partitions).

128 GB SSD Partitions:

/dev/sda
/dev/sd1 efi ------------ Windows Boot Manager
/dev/sd2      
/dev/sd3 ntfs 126GB
/dev/sd4 ntfs 1GB

1TB HDD Partitions:

/dev/sdb
/dev/sdb1 ntfs   300GB
/dev/sdb2 ntfs   300GB
/dev/sdb4 swap   4096 MB
/dev/sdb5 ext4 / 300GB
/dev/sdb3 ntfs   17GB (system recovery)

/dev/sdb4 and /dev/sdb5 partitions were created by me.

What I am confused about is what option should I select in "Device for boot Loader installation"? /dev/sda or /dev/sdb

  • sda is where the EFI partition resides. You should boot Ubuntu in UEFI mode.

The bootloader for your Windows is on SSD. While installing Ubuntu, you should select HDD for bootloader I think. This way, your windows bootloader will not get affected and you will be able to boot into any OS just be selecting the boot drive at boot.
