I currently have OpenSuSE 12.3 on /dev/sda1 which is labeled bootable. I would like to move this version onto /dev/sda2 and install the latest version of OpenSuse on /dev/sda1. I would also like to be able to boot either versions of OpenSuSE. Is this possible and what are the steps required? I assume I need to move version 12.3 from sda1 to sda2 before installing the latest version. Or would it be better to install the latest version on sda2 and hope I can boot either version? Thanks for any help with what I would like to do. Terry

I'd install 13.2 on sdb. GRUB should be able to detect all operating systems and give You choice during boot. If autodetection wouldn't work, You can always set new GRUB entry manually. If GRUB'd be on separate partition, It'd facilitate situation and make it more secure. During installation of 13.2 just pay attention where You are installing to and double-check settings of bootloader. Good luck, Vojtěch

Corrections and Info: 1. what Vojtěch calls "sdb" is "sda2" in your case 2. "GRUB" is grub2 (version 2.00 in 12.3, 2.02~beta2 in 13.2) - Yamaban.

I guess version 13.2 will be installed on sda2.

Depends. What partitioning do you have now? If that's where you have swap now, probably best not to allow any changes that would change it. If not, it's not illogical to expect that sda2 would be the target of an added installation, but if for some reason only you could know you want the new on sda1, you could have it there, among other possibilities, by reordering MBR table entries. I did that once for an inept STB, which demanded an NTFS partition on (external via USB) xda1. I wanted extX on the fastest part of that HD, so that's where I put it, after which I reversed the table entries. The STB is happy to access NTFS sda1, while I'm happy the partition at the front of that HD is extX. If you want guidance and/or suggestions, you should share your current partitioning. What your options are are largely dictated by what you're starting with. Partitioning can be pretty much whatever you want, if you plan ahead. When you don't, options are more complicated and/or more limited. Yet, if there's a plan you can dream up, it's very likely doable. It's usually just a question of how much effort will be requried to implement it. Every Linux installation I have is on a multiboot system, most with no more than one HD, none with less than 3 Linux installations, most with a *lot* more than 3. 13.2 installation provides two bootloader choices, Grub2, and none. I've chosen none in every case for 13.2. It's no big deal at all to boot 13.2 using whichever Linux bootloader you're currently using. If you install 13.2 specifying no bootloader, it's a simple matter to boot 12.3 and have its YaST add an entry for 13.2. If your 12.3 is using Grub, you can do it easily enough without YaST, with whatever plain text editor you like, by copying as many existing entries as you like in /boot/grub/menu.lst, and adjusting as required for the location of the 13.2 installation. You needn't bother with kernel version names. You can use the symlinks vmlinuz and initrd in your stanzas. Those get updated with every new kernel installation, so updates to 13.2 wouldn't cause any need to make any further bootloader change anywhere. If before installing 13.2 you reconfigure 12.3 with bootloader on sda1 (assuming that's not where it already is), you have the option to install 13.2 using defaults, having Grub2 installed, whether to MBR or wherever its / actually winds up (e.g. sda2). 13.2 would then find 12.3 and include it in 13.2's boot menu, same basic way as when someone installs 13.2 on a Windows system. By ensuring 12.3 is booting from / rather than MBR, you ensure that any future changes you might make in 12.3 won't try to interfere with booting 13.2. -- "The wise are known for their understanding, and pleasant words are persuasive."
