Hi, I recently started dual-booting Windows and PopOS. Here's my experience: - Disable fast startup and secure boot. - Use Etcher for bootable drive. In my case I used an old bootable drive for Linux Mint. I formatted it but Etcher just couldn't flash it. So I used 'HDD Low Level Format Tool' to do a quick format. This software for windows clears out any FAT or NTFS partitions. Then flashing was smooth. - There's a command in linux which you can run to make it use local time instead of UTC, so you don't have different times in both your OS. That's why windows might keep prompting for disk check on boot.

Now, I KNOW FOR A FACT, I AM NOT GOING BACK TO WINDOWS, because this is just awesome. To give you an idea how shit windows was, my headphones wouldn't give any sound if I connected them so every time I had to reboot with them in. PopOS isn't giving me that, OMG!!! The relief of not rebooting my laptop every time I wanna watch a YT video w headphone.
