It is possible to do a dual boot with two OS in THIS config? OR is it intrinsically impossible to boot a machine in dual boot with IDE and SATA on the same machine. I do already not understand why the prober does not see the other OS?? Thank you for any tip on how I could achieve this (it is that I feel it to be a waste to through away a working IDE disk only because technology has changed.
You can't count on every kernel version or OS version to find and allocate resources in the same order. This means one may find PATA first, another, SATA first, and how they are reacted to may change according to which is set to HD0 in the BIOS. This is a major reason why recent releases build fstab using UUIDs instead of device names. Likewise, bootloaders can react differently at boot time than during configuration/setup time. I have one machine using a motherboard similar to yours: http://us.msi.com/product/mb/K9N6PGM2V.html#hero-specification It works fine, booting installations on both PATA and SATA disks, without changing BIOS disk order. But, each disk has standard legacy boot code in MBR, and it boots initially from primary partition using Grub, not Grub2, so there's no involvement from os-prober at setup time, and all the configuration is done in the various /boot/grub directories and /etc/grub.confs. Grub2 is installed nowhere. It boots all of 13.1, 13.2, TW, 11.3, 11.4 and 12.2, either directly from the first primary, or by chainloading to the partition from the first primary. http://fm.no-ip.com/Tmp/Dfsee/mcp61L02.txt is its partitioning. As Grub Legacy is still provided by 13.2 and TW, you can replace Grub2 with it. YaST, dracut and perl-bootloader still function with Grub Legacy installed instead of Grub2. You may find, as do I, that Grub Legacy is more easily managed in a multiboot BIOS environment than is Grub2. -- "The wise are known for their understanding, and pleasant words are persuasive."
