Are you referring to 13.2? I'd never seen this before and always gone with the default suggestion of installing the boot files in the extended partition I created, rather than in the root partition or MBR. However, I just did an install of 13.2RC1 and although it suggested this same thing, it also included a line in red text underneath warning that this meant no bootloader would be installed and I could have problems booting the system without further intervention. I did a Google and found a comment from somebody saying they ignored the warning and had no problems, so I did the same. Whether it's a result of that or some other quirk that I've since filed a bug report for, the step in the installer where it configures the bootloader failed. Consequently, I couldn't boot and had to go through the rescue system to fix a strange typo / misconfigured line in the grub.cfg file. I wonder if this line in red text is a bug that will be fixed in the final release of 13.2? Peter PS The option to not install a bootloader could be useful if you already have a bootloader on the system from another install, e.g. another Linux distro, and you prefer to reconfigure that instead of use openSUSE's version. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

Here, it applies to all post-13.1 openSUSE installations from the point when Grub Legacy was no longer an installation time option, and all Fedora installations going back to when it dropped Grub Legacy. Other bootloaders remain available on the repos, just not installable via normal installation process.
& , how might one use such a system that is not bootable?
"Install no bootloader" is not necessarily equivalent to "not bootable". On computers with empty HDs, I first partition, then install legacy MBR code, then format and install Grub Legacy using Knoppix media to boot, but I install openSUSE's Grub Legacy previously saved to LAN, on an active primary partition, not the MBR. Once that's been done once, there's no compelling need for more Linux bootloaders. I manage menu.lst. I decide what belongs in boot stanzas. I have no need for scripts to rearrange my bootloader stanzas. I have no need for complicating my life more than it already is by the inexplicable and confusing differences between Grub Legacy and the overweight Grub2 constantly complaining about not being installed to MBR or presence of vga= on cmdline of a gfxcard unsupported by KMS. The bonus of sticking with Grub Legacy is the pleasant gfxboot menu with penguin=100 configured. AFAIK, Grub Legacy isn't subject to security risk that dictates periodic updates. When I have something that works the way I like, I stick with it until forced to do otherwise. At such time as I have any computers with EFI BIOS will be soon enough to stop sticking exclusively with Grub Legacy. -- "The wise are known for their understanding, and pleasant words are persuasive."

When you want to install your own for instance. E.g. LILO, which YaST had code for up until recently. That code was removed, so now you need to do your own if you want to use LILO. -- Per Jessen, Zürich (14.9°C) http://www.hostsuisse.com/ - dedicated server rental in Switzerland. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

or simply when there is already one installed (other distro), that you want to keep as default. the only (non trivial) advantage of grub is the mini editor that saved my life often (including last saturday) jdd -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
