Some backstory (TLDR: skip to next paragraph). I am a novice linux user, but have been using Ubuntu for quite a while now for my daily tasks. My current laptop of 10 years gave up and now its CPU is always on 80-85% usage on start up. It lags a lot and I am not able to run anything smoothly. Also it randomly restarts. Tried reinstalling Ubuntu, same problem. I think there is some problem in the CPU. We have an “extended family computer”(not mine and it runs windows 10 PRO) which has an M.2 SSD slot free. My plan is to use that one for some months, till I buy a new PC.
What I want to achieve
- Install Ubuntu in the M.2 SSD without modifying anything on the computer.
- The PC should by default boot into Windows, like it does always.(I am not the owner of that PC). This is mandatory as I don’t want GRUB to take over.
- When I want to use the said computer, I will go to BIOS menu and select the SSD to boot from it. So that I will only use my ubuntu installation.
- Virtual Machine is not an option as I do not want to boot into windows at all.
Not sure if this is helpful, but these are the system specs;
CPU – i5 7400
Mobo – ASUS B250
RAM – 8 GB
Most tutorials I find, replaces the default boot loader, which i do not want. So asking here for help.
Thank you for your time.
It sounds like that you know how to install Ubuntu in a separate SSD? If not read this answer.
You can skip Grub entirely by moving it bellow Windows boot manager in Firmware settings. You will find this in boot sequence. Good luck.
