Can dual booting (Windows 10 + Ubuntu 20.04) cause Driver/Hardware issues in Windows 10?

Solution 1:

No. Using Ubuntu will not affect your Windows installation unless you are somehow manipulating files or partitions that are associated with your Windows installation.

Actually, the opposite is sometimes true when you have the "fast boot" feature enabled in Windows 10. That's because fast boot is actually a hybrid suspend that does not fully shut down the system. This can prevent you from accessing resources when you boot Ubuntu after Windows 10.

You might consider learning how to (re)install both operating systems because this is a fairly easy task that you do not need to take it somewhere to have it done.

Solution 2:

Theoretical pondering on Dual boot:
Sleep-mode is likely to save status of hardware and drivers in some way, which may well be inconsistent with what is expected (e.g. from hardware and/or file system status) at the time of boot (or revival from sleep mode?) in the other OS.

Suggestion: Avoid all types of "sleep mode" and fast boot - see if that keeps things working.

If not anything else then you have refreshed (restarted, reset) your OS runtime data at every new reboot.
