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.
FWIW dual booting from the same physical drive is never a good idea in my experience. Even Linux-Linux dual booting is just asking for problems when one of them updates the grub configs and messes it up for the other.
Save yourself some sanity and move your Windows install to a new drive.
This is really the advice to take. I tried dual boot and went back to Windows due to it nuking grub.
Tried again after buying a new SSD and haven't had an issues since
