I think the best (and free) way to save an image of your Windows disc before pushing forward with Linux is to download the free edition of Macrium Reflect 8. You can get it at this link:
Macrium Reflect 8 Free Edition
When you get to that site, page down until you see the link to download Reflect 8 Free and take it from there. Once you have it running on Windows, you will need to do two things:
- Use Macrium Reflect to save an image of the Windows disc on your new laptop. You will need to save that image somewhere other than on that disc itself, so that means on another disc in the laptop or on another computer over your LAN. Note: You can't save an image to a USB drive.
- Use Macrium Reflect to create a Rescue Disc. You will need the rescue disc because once your laptop is changed over to Linux, Macrium Reflect will no longer work because it only works under Windows. So, once you are using Linux, you have to boot your computer using the Macrium Reflect rescue disc, and that will give your computer enough brains to restore your Windows Image. There are instructions on the Macrium Reflect web site explaining how to perform all of the above steps.
Of course, if you are brave, you can install Linux without backing up Windows first. It's up to you. Then, if you want to get back to Windows, you would just have to download Windows from Microsoft (for free) and re-install it. You would lose all of your data, though, and would have to reconfigure everything.
I installed Linux Mint 20.2 Cinnamon. The specs of my computer aren't important because if you have at least the minimum hardware requirements, it will work fine. Minimum hardware requirements for Mint 20.2 are:
- 2GB RAM (4GB recommended for a comfortable usage).
- 20GB of disk space (100GB recommended).
- 1024×768 resolution (on lower resolutions, press ALT to drag windows with the mouse if they don’t fit in the screen).
My laptop has integrated graphics with the CPU rather than a discreet graphics card and it works well.
