Partitioning in RHEL


Where is partitioning information saved in Red Hat.

For instance -
I boot the server - Grub doesn't see partition information....Where is it accessing that information?

Also,

Let's say we rescue boot/live boot. No partitions are shown...Where is that information coming from? Is it the disk...is it a specific disk? MBR?

In the disk but not in the actual Master Boot Record (446 bytes) but after that, in the Partition Table (64 bytes). So with DOS MBR you would 'dd if=/dev/zero of=/dev/devicename bs=446 count=1' to erase the bootloader but keep the PT intact.
