I'm asking about chainloading. Grub has already been loaded via MBR |
| 13 |
and grub's partition (which can be a normal physical partition if |
| 14 |
needed). Grub is now running and displaying its menu. Each of the menu |
| 15 |
entries instructs grub to load the first sector of a specified |
| 16 |
partition into RAM and execute it. That sector can contain grub, LILO, |
| 17 |
windows boot manager, whatever. If grub understands LVM volumes, then |
| 18 |
can it read that first sector from an LVM volume instead of a physical |
| 19 |
partition? |
