In the absence of being told the disk and partition, GRUB will use
(hd0,msdos1). The OP did not specify more than one disk and partition.

Yes, either debootstrap (used also by the Debian Installer) or mmdebstrap can create a "blank" Debian installation. Please mind that it will need additional configuration in order to make it work, including but not limited to creating users, setting up your fstab (in case you more partitions), etc. that are normally done by the installer. > I do have a running > debian 10 system on another machine, and i suppose i could tar it up and > unpack it into the new partition on the mint machine. Cloning another installation presents its own challenges, as you might end with stuff duplicated that should be unique for each system (unless you really know what you are doing). It's probably easier to just let debootstrap/mmdebstrap take care of the bulk installation and use the other Debian installation only as a source of configuration files. > But i'm not sure if > there's something outside the filesystem but inside the partition which is > necessary for it to be bootable. It depends. With GRUB on traditional BIOS (non-UEFI) systems there are several approaches possible, depending on which (if any) is your "primary" system (i.e. the one that provides/controls the boot loader). More details are needed here to provide useful recommendations. Kind regards, Andrei -- http://wiki.debian.org/FAQsFromDebianUser

Any kind of medium that can be used by your motherboard to boot should work (e.g. a spare SATA drive), same as you would be using a USB stick (including loosing all data when copying the .iso to it). If using the 'mini.iso' in the 'netboot' category you can even install to the same drive (the other images don't allow repartitioning of the drive (partition?) they are on).

Providing more information will allow readers to provide better answers:
- The make and model of the computer. If homebrew, the make and model
of the chassis and motherboard. Please provide URL's.
- How many drive bays the chassis has.
- Makes and models of drives in the computer, and which bay each is in.
Please provide URL's.
- How many and type of drive interfaces on the motherboard and/or
HBA(s), and which drive is connected to which interface.
- The purpose of each drive, what it contains (e.g. partitioning scheme,
slices/ partitions, LVM, dm, ZFS, LUKS, filesystems, etc.), and which
one you want to put Debian on.
- The *.iso filename of the Debian Installer you want to install from.

I think this question got overlooked earlier.
If by "bios" you mean BIOS/CMOS/UEFI, then there might be. I have
noticed that my AiO Dell has the following paragraph inserted
into grub.cfg:
### BEGIN /etc/grub.d/30_uefi-firmware ###
menuentry 'System setup' $menuentry_id_option 'uefi-firmware' {
fwsetup
}
### END /etc/grub.d/30_uefi-firmware ###
This is all new to me as the Dell is my first PC that I boot through
EFI. (My other EFI-capable PC still boots linux via BIOS because
Windows was pre-installed with EFI.)
The effect of selecting this grub entry is exactly the same as
pressing F2 durimg POST and before the grub menu pops up.
I suppose the mechanism might be contained in the grub module:
root root 2216 Jul 30 18:18 /boot/grub/x86_64-efi/efifwsetup.mod
Cheers,
David.
