1. The first choice offers me the option to Boot from Boot Partition. I cannot find a definition of what a "Boot Partition" is exactly, but my guess is that this is a partition that I will set fstab up to mount as /boot Is that correct?
probably. Necessary is the boot loader can't read your root file system. better have one for each distro installed
2. The second choice is Boot from Extended Partition.
notice this menu is about the place to install the boot loader. You can set it to the extended partition. specially if you use XFS that don't allow using root partition.
3. The third choice is Boot from Master Boot Record.
this is the safer system if one use only one installed sytem (obviously not for you). If you use many, each new one will install it's own boot manager and you have to hope it's able to boot the others
correctly, the device referenced as /dev/sda1 on my openSuSE11.0 system is NOT the same device referenced as /dev/sda1 under openSuSE11.2
I have no sata drive, so I don't aster the sata drive order
The fourth choice is to Boot from Root Partition and again I am guessing that this really means to boot from the partition that I will configure fstab to mount as / Correct?
yes. It's better for any file system GRUB can cope with. I use to install grub for any distro on the root of this distro and one more on MBR. like this I get two cascading menus (MBR one, then distro one)
that I should select "Set active Flag in Partition Table for Boot Partition" Why???
it's where the system looks for boot manager when there is none in the mbr Do I have to have a separate Boot Partition in order
to use this Boot from Root Partition option?
no any partition where /boot is located
If I am going to choose to boot from the Boot Partition do I also have to explicitly tell YaST to Write Generic Boot Code to MBR,
only if the MBR was used previously for any boot manager it'sv also better *not* to try to set GRUB in several place at the same time (YaST allows clicking several places), if you want so, set them up on two steps read this :-) http://wiki.tldp.org/Partition-Mass-Storage-HOWTO jdd -- http://www.dodin.net http://valerie.dodin.org http://news.opensuse.org/2009/04/13/people-of-opensuse-jean-daniel-dodin/ -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

Active flag is relevant only when set on a primary partition and the MBR code is standard legacy PC BIOS compatible or equivalent (standard/generic boot code). Standard MBR code searches for a primary partition with its active flag set. If if finds more than one primary with its active flag set it gives a boot error. If if finds only one it relinquishes control to that partition's boot sector. -- " We have no government armed with power capable of contending with human passions unbridled by morality and religion."
