Error on boot openSuse

I have openSuse 11.0 installed, it was running ok but yesterday I got a message that there were some updates available, I downloaded and installed the files and when I rebooted the system I got a message : Filesystem type is reiserfs, partition type 0x83 kernel /boot/vmlinuz- root=/dev/disk/by-id/scsi_SATA_TOSH IBA_MK8025G_Z5N25606S_part2 resume=/dev/sda6 splash=silent vga=0x317
Error 15:file not found
It doesn`t boot anymore. What I should do now?

First. Why are you not using ext3?

But your problem has been caused by a kernel update I guess.

Re-install the bootloader

help here:
GRUB Boot Multiboot openSUSE Windows (2000, XP, Vista) using the Grub bootloader.

The key thing to remember is: MBR
