MX 23 dual boot with Windows 11- tutorial needed.

My personal retirement hobby is tech writing. This might be of interest to you - Dual Boot How-To guide: brief

I'll even throw you a bone (to save you more reading) and copy the entire section on how to install MX Linux below.

4.0 MX Linux Installation

Your PC is now ready to install MX Linux on the newly create partition.

• Install MX Linux, making sure to use the same Boot Mode (UEFI vs. BIOS/CSM/Legacy) as your Window’s installation.
• Allow the MX Linux installation to install the Grub Bootloader.
• DO NOT REBOOT!
• Run “update-grub” in a terminal window after the MX Linux installer is closed.
• As the above runs “Windows Boot Loader” should show up.
• Reboot.

Yes, that's all of it.

Suggest review this part: »Run “update-grub” in a terminal window after the MX Linux installer is closed."«
As update-grub running in terminal on a MX LiveUSB, won't work for two reasons:

1st: You will see this error: failed to get canonical path of `overlay'."

2nd: Even it it would work, update-grub generates the grub-menu config file at location /boot/grub/grub.cfg.

But boot- or /root-partition of the freshly installed System is not available (or better not mounted ) on the LiveUSB.

Also with the latest installer this addtional step might not be needed anymore to get the windows menuentry listed.
Otherwise if still needed, either run "update-grub" within the booted installed system or run within chroot-terminal e.g. by using "Chroot Rescue" to "visit" the fresh installed System. Or even use MX Boot Repair from the LiveBooted System.

Thank you fehlix for the valuable feedback. Other (external to this forum) reviewers missed that error on my part. Document updated.
