How do I set the order of systems in grub?
There are 3 systems: Windows, Linux Mint, and Debian.
Now the download list looks something like this:
Windows
Debian
Дополнительные параметры для Debian
Linux Mint
Дополнительные параметры для Linux Mint
memtest
memtest serial console
How do I make Linux Mint the second one?
Windows
Linux Mint
Дополнительные параметры для Linux Mint
Debian
Дополнительные параметры для Debian
memtest
memtest serial console
And is it even possible to get the following order?
Windows
Linux Mint
Debian
Дополнительные параметры для Linux Mint
Дополнительные параметры для Debian
memtest
memtest serial console
Windows and Debian are installed on the first physical disk (MBR)
Linux Mint is installed on a second physical disk (GPT)
UEFI no, booting from the first disk.
Grub enastraivayu from Mint.
The file renaming suggested in the comments doesn't help:
qwertiy-Z68AP-D3 grub.d # ls -l .

qwertiy-Z68AP-D3 grub.d #
In /boot/grub/grub.cfg found that Debian is inside
### BEGIN /etc/grub.d/03_os-prober ###
### END /etc/grub.d/03_os-prober ###
So, it finds Windows and Debian together and manipulating the file order will lead to nothing?

You can swap the menuentry sections in /boot/grub/grub.cfg as needed. this file is read (and interpreted) by the loader at each launch directly, i.e. the file changes are "picked up on the fly".
Syntax of the section:
menuentry "заголовок" [опции] { команды }
Sections menuentry can be nested in sections submenu (sub-menu). the resulting file may look like this, for example:
submenu "заголовок" [опции] {
menuentry "заголовок" [опции] { команды }
menuentry "заголовок" [опции] { команды }
}
menuentry "заголовок" [опции] { команды }
Drawback: executing the script /usr/sbin/update-grub will return the order of the records "back to normal". a is called this script, at least, when updating packages with programs linux and grub.

They also write that you can use the grub-customizer package, among the features of which:
- move, remove or rename menuentries (they stey updatable by update-grub)
Disadvantage: judging by the information from packages.ubuntu.com, this package is not included in any of the supported ones repositories.
Supplement 2
So that the file /boot/grub/grub.cfg is not overwritten when updating packages with the program linux, you can replace this file name with some other one in the script /usr/sbin/update-grub (for example, /boot/grub/grub.cfg.new), and update the file manually. replacement example:
$ cat /usr/sbin/update-grub
#!/bin/sh
set -e
exec grub-mkconfig -o /boot/grub/grub.cfg.new "$@"
Disadvantages:
- you will have to manually keep the
/boot/grub/grub.cfgfile up-to-date (based on changes in/boot/grub/grub.cfg.new). - when updating the package grub2-common (or another one containing the mentioned script
/usr/sbin/update-grub), you will have to correct both/usr/sbin/update-gruband/boot/grub/grub.cfgagain.
