Then still you can set Linux as default. Lilo had an option to reboot with an option to set a 1 time default. (that was neat)
On dual boot hardware, I always set the one I want to default boot, which is in my case always Linux. (must still have a dual boot laptop somewhere)
Most people are tech illiterate. Ask them anything but to use a pre installed system or pop in a CD that was given to them (No they can't burn one themselves) and they'll fail
With all the UI changes on every version in the last few years that simply isn't true. Windows is becoming harder and harder to use even if you know what you are doing, much less if you don't know half the computer related terminology.
I was in that situation a while ago, so I booted in to try and keep it up to date. Well, in reality I booted into recovery mode as it decided to die. Anyway I'm now duel booting arch and tumbleweed
When the windows update bricked my OS I sighed in pure relief as I could finally stop using windows forever.
As an added bonus I didn't lose any work because the drive was fully accessible to arch.... after windows said it had encrypted the drive.
Absolute trash operating system and I have zero regrets leaving.
Ah old days... I used to boot into Windows 10 just for gaming but when Valve's Proton matured to the point that all my games could work on Linux I very happily nuked it out of existence. But yeah if someone plays Fortnite or needs Adobe products then you still can't do much unfortunately.
I only played via Steam so I wouldn't know. I hear it's a good deal, but I've made it a point to not accept such good deals from BigTech. Have gotten screwed over too many times. Remember when Google Photos allowed unlimited storage?
