I have a laptop Lenovo IdeaPad S340. Inside the laptop is the native NVME M.2 and I installed the SSD 2.5. I plan to use Windows for games, Ubuntu for work. I want to install Windows 10 and Ubuntu 18.04 LTS on different drives. When installing Ubuntu, I would like to encrypt the hard drive. I also want to hide a Windows disk from Ubuntu to avoid damaging the file system.
My plan was to disable SSD 2.5 in BIOS and install Windows on NVME M.2. Then disable NVME M.2 and install Ubuntu on SSD 2.5. When I boot, I just select the drive I need. Perhaps for experienced users this seems primitive but it is ideal for me because of it simple.
But my Lenovo laptop has a limited BIOS with advanced settings disabled, so I cant manage SATA and PCIE configurations. I called Lenovo support and they refused to help me unlock the BIOS.
So here is what I have:
The BIOS says that plugged SSD 2.5 in SATA port 1, NVME M.2 in PCIE.
The Windows USB installer defines SSD 2.5 as drive 0, NVME M.2 as
- The Ubuntu USB installer defines NVME M.2 as /dev/nvme0n1, SSD 2.5 as
SCSI2 (0,0,0) (sda) – /dev/sda.
Default settings in the BIOS:
- Boot Mode – Legasy Support
- Boot Priority – UEFI FIRST
- Fast Boot – Enabled
- Secure Boot – Disabled (Unactive, grayout. It only becomes active if
select Boot Mode – UEFI.)
To be honest, I'm confused.
- What BIOS settings should I use?
- Which operating system should I install first and on which drive? I
ask this because Windows installer define SSD 2.5 as the first disk,
and Linux installer define NVME M.2 as the first disk.
Please help me find the best solution.
I decided to install only Windows. Without Linux. This is too hard for me. Thanks to all.
