I can't remember if this was already the case with 11.3. The first (sda1) partition is a very small one (I don't know why). Windows 7 is on the second one (sda2) and the Recovery partition is the last on sda4. Grub identify correctly the windows partition when making menu.lst as (hd0,1), but sees it as (hd0,0) at boot time. So the default menu can't boot Windows. I couldn't fix this with YaST and had to use vi...

I don't remember if it's at install time or only from the partitionner afterward, but grub happen to write one menu entry for each windows partition, so there is one that boots, but it's not the normally numbered one. (hd0,0) boot when it should be (hd0,1)
Windows 7 comes with a separate boot partition. So sda1 is correct even so the Windows system is on sda2.
so it's only a Windows gymnic. Thanks, I close as invalid. Funny that Windows do this when we do not anymore :-)
Don't you worry, we'll follow soon enough. :-) uefi practically forces you to and btrfs support in boot loaders might still take its time. Anyway, we need to produce a correct boot config, no excuses. I'll reopen. If you feel better about it, lower severity.
if you want. It's pretty difficult to test installs again and again :-(, but when used from a running distro, grub writes one menu.lst line for each widows partition, so there is of course one that works, you have only to guess which :-) I'm not sure this is a bug
