Every time Windows updates itself, my Linux disappears. Actually, it's just hidden, only the boot menu was overwritten. You need a computer maintenance technician to make a new boot menu. I use a USB stick with a live Linux with automatic boot repair tools.
Recently, Windows has become resistant to Boot Repair Disk. Now I have to open computer firmware by tapping "Esc" right after power-up, then select "Boot options", then "Linux".
EU must ban all US-made smart products for its own safety. All closed-source software and electronics that can be used for strategic manipulation and sabotage -- Google, Apple, Amazon, all of it.
We have functional, clunky open-source software that could easily be fitted for any purpose with the money we waste propping up foreign monopolies sabotaging us. Europe has taken a huge risk. I suspect bribery.
I use Windows 1-2 times per year, so I don't know how often the boot-breaker comes. This has happened to me on four computers with Windows 10-11. Always with both Linux and Windows on the same drive, which is key, says another comment here.
Oh that might be it then
