My Fedora system has two (identical, but that doesn't matter) disk drives.
Fedora is installed on /dev/sdb which uses LVM. Currently /dev/sda is partitioned the 'old fashioned' way. Now that I'm happy with the Fedora installation I want to tidy things up and use LVM for /dev/sda as well.
Backing up and copying the data across is straightforward enough, I can cope with that. I have enough space that I can empty /dev/sda completely and partition it from scratch.
However what worries me slightly is that there is presumably an MBR (that's what DOS used to call it) on /dev/sda which the BIOS goes to when the system is powered up. If I repartition /dev/sda will I lose this boot record? How does this get created in the Linux way of doing things?
