[SLE] Strange problem with grub
Hello all, I have a strange problem with grub. I am using SuSE 10.1. I have installed (open)SuSE 10.1 but after installation I cannot boot windows any longer... This seems to be a recuring problem. I have googled around a bit and found all kinds of diagnostics and tips which all did not work. E.g. - reinstall windows after linux - boot with a windows-cd and use the windows-tools fixmbr and fixboot - ... The strange thing is: If I am booting with a SuSE 10.1 installation-CD and choose "Boot from harddisk" I can boot windows very well! Only if I do not boot from CD but directly from harddrive, I cannot boot Windows (it says "NTLDR is missing", which is _not_ true...) from the grub-menu. grub is also mangling the partition table entries. When booting from CD, my first harddrive is hd0. If I am booting directly from harddrive, I have to choose hd1 as the first harddrive... Do you know, how to solve this strange behaviour? Any hints or suggestions are welcome.

Something a bit like this happened to me. I run three Linux distros on two disks plus a 98SE partition that I don't boot up any more. When I installed 10.1 on one of the Linux partitions, not only did it hijack the MBR GRUB, ignoring my main working Linux on the second disk, but it made the partition 10.1 was on "bootable", and not the 98SE partition - fdisk -l of hda shows: Device Boot Start End Blocks Id System /dev/hda1 1 1266 10169113+ c W95 FAT32 (LBA) /dev/hda2 1267 2988 13831965 83 Linux /dev/hda3 * 3067 4865 14450467+ 83 Linux /dev/hda4 2989 3066 626535 5 Extended /dev/hda5 2989 3066 626503+ 82 Linux swap / Solaris I have not tried to boot 98SE, and as I am having no booting problems, after rebuilding GRUB, I have not looked at how to get hda1 "bootable" again. Perhaps someone else can help there, if this is indeed your problem. I have not tried re-installing, but I gather there is a checkbox about "activating" the 10.1 partition in the boot options in the "expert" tab that if left checked will have the above effect. Does anyone with a deeper understanding care to elaborate?

Andy, I'm pretty sure both lilo and grub ignore the "bootable" flag. Note that only one partition can be marked bootable at a time. With the standard non-menu based boot process, the bootstrap looks to see which partition is marked bootable and that is the partition is uses to do the boot. Again I don't think lilo nor grub pay any attention to the flag.
