Hallo-
In the wake of a friend's recent LILO problems (plus that Chernobyl
thing for the dual-booters amongst us, I suppose), I've got a couple
questions regarding the preservation of a disks or md set's MBR.
What is the proper way to preserve the master boot record for a
single disk? Can I just dd the first 512k to a floppy? 512k is just a number
I've heard; do different disks have differently-sized boot records and
partition tables?
What is the proper way to preserve the mbr for a bootable stripe
set?
Either way, if someone was to clean out your partition table with
fdisk, or wipe out your boot sector with lilo, what sort of backup would you
like to have on hand to recover quickly? Any special considerations for md
sets (bootable or otherwise)?
Thanks!
