    If you install each OS with it’s own drive as the boot device, then you won’t see this issue.

    Unless you boot Windows via the grub boot menu. If you do that then Windows will see that drive as the boot device.

    If you select the OS by using the BIOS boot selection then you won’t see this issue.

    I was bitten by Windows doing exactly this almost 15 years ago. Since that day if I ever had a need for dual-boot (even if running different distros) each OS will get it’s own dedicated drive, and I select what I want to boot through the BBS (BIOS Boot Selection). It’s usually invoked with F10 or F11 (but could be a different key combo.

    While I generally agree with that, that’s not what seems to be happening here. What seems to be happening is that anyone who boots Windows via grub is getting grub itself overwritten.

    When you install Linux, boot loaders like grub generally are smart and try to be helpful by scanning all available OSes and provide a boot menu entry for those. This is generally to help new users who install a dual-boot system and help them not think that “Linux erased Windows” when they see the new grub boot loader.

    When you boot Windows from grub, Windows treats the drive with grub (where it booted from) as the boot drive. But if you tell your BIOS to boot the Windows drive, then grub won’t be invoked and Windows will boot seeing it’s own drive as the boot drive.

    This is mostly an assumption as this hasn’t happened to me and details are still a bit scarce.

    The level of inaccuracy in a regular clock resulting in drift is orders of magnitude greater than any amount of time dilation you would experience.

    This is the reason we use extremely high precision clocks (like atomic clocks) and then synchronize everything else with them. Even your phone’s clock would drift noticeably over a period of a few months if it never synced with some network server.

    The NTP protocol exists precisely for this. There are entire companies that specialize in providing and maintaining synchronized wall clocks for facilities like hospitals, schools, and other organizations.

    I just got awnings installed two months ago on the windows that get sun for most of the day. It dropped the temps in those rooms by almost 8 degrees Celsius on hot days. The AC even runs less during the day now.

    They’re simple retractable awnings that a local guy installed for me. I used to hate the idea of awnings, but the thought about IR heat getting trapped clicked with me recently and suddenly the idea of awnings seemed brilliant.
