Don’t rely on walmart product reviews. I on more than one occasion have left less than favorable reviews on products themselves which was valid issues with the product, and they accept the review… and then never actually post the review for everyone else to see.
What you see isn’t an accurate representation of the products, bad reviews rarely get posted. Take everything with a grain of salt.
I think a big reason is, people always think it’s an all or nothing migration. Personally I still have a windows install on my system from when I migrated. Sure I can count on one hand the number of times ive had to actually use it, nor have I had to at all in the past few months, but it’s there in case I needed it.
I think people would be much more apt to do that, if they could realize that you can “try it” and if it doesn’t work then switch back again without much difficulty. Which most user friendly installs support dual booting, and the worse case scenario from it is that Windows decides to nuke the bootloader (which doesn’t happen as much anymore due to it changing to UEFI boot) and then at the end of the day, they still have the windows OS to fall on, and the linux OS still exists, it just doesn’t know its there which is a simple fix with just a google search and a boot repair disk (available on the same install medium that the original install was done with)
