I have a two hard drives, one has Windows 7 and the other hard drive has OpenSuse 12.1, when I get ready to install 12.2, I have almost 958 gb on the OpenSuse 12.1 drive, if I remember right, on the initial install windows I can resize the 2nd drive in half, so I can load OpenSuse 12.2 in the other half of the drive, so essentially I would have: SDA, then SDB (12.1) and SDC (12.2) on the partitioning, Is this correct thinking and will Grub 2 handling the MBR? Is this process sound?
Yes, you can re-size the openSUSE 12.1 harddrive to allow space for your 12.2 installation.
In fact, because there is a /swap partition on your second hard drive, it can be shared between the two openSUSE systems!
If openSUSE is being installed onto an “extended partition” than it will install the boot loader there, otherwise it looks for a /boot partition or right into the MBR of the HD.
I usually install the boot loader into an extended partition if I plan on dual booting other OS, especially Windows.
Your hard drives will be identified by a single letter and the partitions with a separate number:
**Hard Drive 1:
**/dev/sda
-> /dev/sda1, Windows7
Hard Drive 2:
/dev/sdb
-> /dev/sdb1, / aka “root” for 12.1
-> /dev/sdb2, /swap for 12.1 and 12.2
-> /dev/sdb3, /home for 12.1
-> /dev/sdb4, / aka “root” for 12.2
-> /dev/sdb5, /home for 12.2
Those aren’t going to be the partitions you have exactly, but should give you a good idea on how openSUSE identifies your hard drives and partitions. There could be several other /dev/sdbn for your openSUSE installation depending on the filesystem(s) used (ie, ext2/3/4, btrfs, xfs, reiser, etc).
