I'm preparing my first dual-boot installation on an ASUS TUF F15 FX506HC with an i5-11400H, RTX 3050, 16GB of RAM, and Windows 11 already installed. I've shrunk the Windows partition and left 100GB of unallocated space for Linux Mint Cinnamon.
I'm concerned that a Windows update might change the boot order or interfere with GRUB and leave Linux—or even Windows—unable to start. How serious is that risk with modern UEFI systems, and what should I back up or learn beforehand so recovery is straightforward?
Specifically: should Fast Startup and Secure Boot be disabled; are there known black-screen or graphics-driver issues with this Intel/NVIDIA Optimus laptop; should I let the installer use the unallocated space automatically or create partitions manually; and what is the best way to ensure both operating systems remain available after updates? I'd also appreciate any first-time dual-boot advice or common mistakes to avoid.

The RTX 3050/Intel Optimus combination can show a black screen depending on the kernel, display mode, or NVIDIA driver. If the live USB has trouble booting, try the compatibility or `nomodeset` option temporarily. After installation, install the recommended NVIDIA driver through Mint’s Driver Manager and test both the integrated and NVIDIA modes. Keeping the laptop in hybrid graphics mode initially is usually the least troublesome choice.
GRUB normally detects Windows automatically. After installation, check that the firmware’s boot order points to the Mint/GRUB entry. If a Windows update makes Windows first again, changing that UEFI order is often all that’s needed; it doesn’t necessarily mean GRUB was damaged.
Make a full image backup of the Windows installation to an external drive before changing anything, and create a Windows recovery USB. Keep the Linux installer USB as well. It’s also wise to back up the EFI System Partition, although Windows updates generally don’t erase its files. More commonly, firmware or Windows changes the default UEFI boot entry so Windows starts directly.
If that happens, you can usually select the Linux/GRUB entry in the firmware boot menu or restore it with a live Linux USB. Boot Repair or manually reinstalling GRUB from a chroot are useful recovery skills, but most cases don’t require anything drastic.
Disable Windows Fast Startup, and preferably hibernation too, because leaving an NTFS Windows volume hibernated can cause problems when Linux accesses it. Secure Boot can work with current Mint releases, but disabling it during installation is often simpler, especially if you later install NVIDIA’s proprietary driver. If you leave it enabled, use a current official ISO and follow the prompts for driver or MOK enrollment rather than forcing unsigned modules.
For the disk layout, manual partitioning gives you the most control. Use the existing unallocated space for an ext4 root partition mounted at `/`; a separate home partition is optional and usually unnecessary for a first installation. Swap can be a swapfile, which Mint handles automatically, unless you specifically need hibernation.
Select the existing EFI System Partition as the EFI location, but do not format it. Do not modify or format the Windows recovery partitions. If the installer offers a safe ‘install alongside’ option and you’ve verified the partition sizes, that can also work, but review its proposed changes carefully before confirming.
That clears up the difference between GRUB being deleted and the firmware simply choosing Windows first. I’ll make the image backup and recovery USB before installing.
