2) use these incantations, lifted from a post elsewhere :

mount --bind /sys /sysroot/sys
mount --bind /proc /sysroot/proc
mount --bind /run /sysroot/run (recommended if you are using systemd)

*Exactly* what do you mean by "your-grub-boot-device"? Does it vary
depending on MBR vs UEFI?
Yes, it varies depending on BIOS vs. UEFI boot. For bios boot, the grub
boot device is the drive whose mbr you want to use, like /dev/sda or /dev/sdb.
For UEFI, you don't name the device. Grub knows to put the bootloader in
the efi partition. In that case, an extra step above would be to mount the
efi partition to /sysroot/boot/efi
So now you've installed Grub(2), but then how do you configure grub?
While you are still in the chroot, run:
update-grub
And that will make a new boot menu.
