[Bug 450963] New: grub installed in MBR and broke the system, instead of installing it to root partition
https://bugzilla.novell.com/show_bug.cgi?id=450963 User jdsn@novell.com added comment https://bugzilla.novell.com/show_bug.cgi?id=450963#c450268 Summary: grub installed in MBR and broke the system, instead of installing it to root partition Product: openSUSE 11.1 Version: RC 2 Platform: Other OS/Version: Other Status: NEW Severity: Blocker Priority: P5 - None Component: Bootloader AssignedTo: jsrain@novell.com ReportedBy: jdsn@novell.com QAContact: jsrain@novell.com Found By: Development I inststalled openSUSE 11.1 RC2 via HTTP and selected to install the bootloader into the root partion (/dev/sda10). When the system rebooted after first stage the system was not able to boot any more: "No operating system found". The MBR (of /dev/sda itself!) was altered. With the rescue system I created a copy of the current MBR and reapplied the saved original "backup_mbr" and could then start the second stage. These MBRs differ. I will attach the yast2 logs, see at timestamp "2008-12-02 09:38:05". Please tell me if I should attach the two MBRs as well. I don't know if this is a duplicate of or related to bug #450268. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

YaST always writes generic bootloader code to MBR by default, which probably happened to you (if there is some mess there, system cannot boot otherwise)
Even if I select not to do it, as I wanted to keep my MBR?
If you want to keep MBR in other situations, you need to ensure it is not affected
How? In the installation I selected to write grub to the root partition and not to the MBR. This was sufficient for all previous releases. How to it now?
(but then your system may not boot out of the box)
Well, it did, because I know the current MBR is correct (thats why I wanted to keep it). And after I replayed the "backup_mbr" it works again.
there is a check box to enable/disable writing generic code to MBR
According to the scenarios document, your scenario (GRUB to a logical partition) is not supported and is not supposed to work out of the box.
I am not complaining that it does not work out of the box. I wanted to point out that the MBR was changed even though I selected _not_ to do it. I did another test with RC2 to see if it is reproducable - it is! So I reopen this bug. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

Did you uncheck the "Write generic boot code to MBR" check box in the "Boot loader options"?
Thanks for the hint - I found the option. With this checkbox unset now the MBR is kept untouched. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
