I'm a programmer who also does design work and gaming. I used Windows for years, but I've been gradually moving to Ubuntu. I still need Windows for certain games and Adobe applications, so I've kept both operating systems installed.
The dual-boot setup worked well at first, but lately I've been running into problems. The clock is often wrong after switching between systems, display settings sometimes change unexpectedly, and Windows occasionally refuses to boot because of corrupted files. Is there a recommended configuration or troubleshooting process that would let me keep both systems installed without these issues?

The clock mismatch happens because Linux and Windows handle the hardware clock differently. One option is to configure Linux to treat the hardware clock as local time with `sudo timedatectl set-local-rtc 1`. It’s also important to disable Windows Fast Startup and hibernation, since they can leave the Windows filesystem in a partially suspended state and cause problems when switching operating systems.
If the installation has become unreliable, a clean reinstall is often the most dependable fix. Back up everything first, then install Windows on an empty drive, use Windows Disk Management to shrink its partition and leave unallocated space for Linux, and install Linux afterward. The Linux installer should then configure the boot menu automatically.
Installing Windows first and shrinking it immediately avoids some of the awkward partition and system-file issues that can happen when trying to resize an older Windows installation. Afterward, disable Fast Startup and hibernation in Windows, and configure the clock handling so both systems agree. This setup generally works well for switching between Windows 11 and a modern Linux distribution.
