probably. Necessary is the boot loader can't read your root file
system. better have one for each distro installed

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

I have no sata drive, so I don't aster the sata drive order

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)

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

no any partition where /boot is located

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
