If you have extra USB-stick, create a recovery drive. It's VERY easy and can save you from many headaches.

Many people don't know this but Windows comes with built-in feature that allows you to create a recovery drive, no software needed.

Simply search for it, it's already there. If you have an extra USB-stick that is not in use, consider doing this, as it can really help you recover if you cannot boot into Windows or face other similiar problems in the future. Keep in mind that creating a recovery drive wipes everything stored on the USB device and that you've chosen the right one - the tool will also warn you about this.

Recovery drive is essentially a bootable drive, which contains all of the common troubleshooting tools. For example, you can fix system files from there, do startup repair (incl. fixing the bootloader) or request your PC to boot into safe mode, which is especially good when dealing with OEM driver issues, like GPU. This is equivalent to recovery partition, which comes as part of Windows installation but sometimes it might not be possible to access this partition depending on the issue.

One very significant advantage why I love this feature: when you create a recovery drive, you can choose to back up your system files. This ultimately means that you'll have a (full) copy of your system on the drive during a state when it was functional, aka a system image backup. You can reinstall Windows from this backup, which has several benefits over using official installation media, such as preserving all of the OEM drivers for full hardware support. No need to hunt for them after the reinstallation.

If you back up system files, make sure to update your recovery drive from time to time, e.g. once a year when feature update has been rolled out, so the drive contains a somewhat up-to-date image. It takes approximately an hour to create it (depending on USB speed) but you can schedule it when you're not using your PC. However it often won't take all system resources if you're writing on slower USB-stick, so it's typically possible to use the machine while it's doing it.

Remember that this won't save your data. This is only for system recovery. Use other methods for data backup.
