I've been puzzling over this one for a while now.... not quite sure how or why openSUSE is seeing my hard drives in a different order than the BIOS and the physical connections are laid out.
... Don't fight what you can't control. Mount volumes by UID or volume label and move on to the next problem.
:-) Normally, this is not a concern, and mount by UID works perfectly... well... it still works fine in this case too, but I stumbled on a minor hiccup so to speak that could possibly trip up new users... and old timers too.
I installed a new drive. With all that space I decided to install Ubuntu Kooky Koala or whatever it's called, and also openSUSE 11.2 m6. They merrily installed (I used all defaults during the install process)... both installs saw the existing 11.1 install and offered to add it to GRUB. On reboot though, I get the 11.2 GRUB menu which only has 11.2 and 11.1 in the menu... no Ubuntu Koalas. If I pull the old drive out, then Ubuntu boots fine. Put it back in... and the Koala is hiding. OK, I can deal with this as it's just Ubuntu putting it's boot bit on the wrong drive - the hard part is guessing which drive the MBR is hiding on.
Does your BIOS have a selection "Disk boot order" ?
Oddly, if I select to boot 11.1 in the 11.2 GRUB, it hands off too... the 11.1 GRUB, and I have to select 11.1 a second time in a second GRUB menu. Messy :-(
One interesting thing through all this is how robust and persistent the boot sector is... and I'm not exactly sure why or how it works... no matter the physical configuration... swapping the SATA drive connections around at random seems to have no effect on booting Linux. No matter the drive order, 11.1 would still boot (this was before I started installing other OSes). Some configurations show an error hd(0,0) not found, but it still boots. I thought that was rather interesting.
So.... this is what lead me to start poking at the drives, the physical order vs the order Linux sees them... and trying to find the "easy" way around this. In the end I want a single GRUB with all installed OSes. I can probably get there myself, but...
It used to be you had to have the right info in the MBR of the first drive to be able to boot your OS. Is this still the case? If ti is... which drive is the first drive now? If I shuffle the physical connections, things still boot up... so I'm a bit puzzled. :-P
