How can I do that? Anyone know? I use my disk as GPT. Windows 10,
Debian 11 (GRUB) already exists as dual-boot, but I want to install
FreeBSD next to it. How will I do? Thanks.

You can use your system's existing UEFI support (easy to manage with
FreeBSD's `efibootmgr` command. I don't know how you could configure
GRUB, but I use ReFind in a similar role as my boot manager for macOS,
Windows, and FreeBSD.

bilmiyorum, ancak ReFind'i macOS, Windows ve FreeBSD önyükleme
yöneticimle benzer bir rolde kullanıyorum.efibootmgr

Thanks for ur help. How can I use rEFInd? Is it safe? And how can I
configure this for triple boot. -FreeBSD, Windows and Linux-

just free up some space, boot into freebsd live usb and in the
partitioning process hover the disk, click add and add a partition of
type, \`freebsd-ufs\`. EFI partition probably will be detected, if not
- select your efi partition and change mount point to /boot/efi. The
installer will not format it.

The part I don't know how to do, or if it's possible, is to leave
secure boot enabled. You can run windows 10 just fine without secure
boot but the windows11 updater complained and won't let me upgrade
because I have secure boot disabled. Supposedly, someone made a
version of their updater that disables the check and everything works.
However, that may cause issues down the road if they check for secure
boot on each update.

Just something to think about.

[Windows 11 is installable without secure
boot.](https://makmodo.com/install-windows-11-without-tpm/). One
method out of several.
