Then you can goto Yast → system → bootloader and do this:
The Grub configuration screen comes up with the Tab “Section Management” activated. In the lower right is a drop-down selector labelled “Other”. Select from “Other” the option “Propose New Configuration” and then wait for Grub to analyse your partitions and display a new configuration. This may take a while. Important: When that finishes, activate the tab labelled “Boot Loader Installation” and select to “Boot from the Master Boot Record”. [Yast will often default to booting from the root or boot partition rather than from the MBR but that’s for experts only – always choose the MBR.] Then click Finish to save the changes and install the reconfigured Grub into the hard drive’s MBR. If you get a message that "The bootloader boot sector will be written to a floppy disk … don’t bother with the floppy – just click OK to proceed and install to the MBR.
I tried everything you replied but still no Suse, the error I get is:
VFS: Cannot open root device “<NULL>” or unknown-block (8,9)
I tried to repair the bootgrub with the suse 11.1 DVD option Install and with the option repair, both ended in the same message I saw in the beginning. With this extra error. Also my windows XP is gone in the Grub…HELP!!!:(:(
