Currently I have windows 2K8 R2 on first HD and SL6 on the second. Super Grub doesn't get the job done so I guess I need to add an entry to /boot/grub/grub.conf. Before all, if there is a tool that can automatically fix this, I'd be happy to know about it. Here are the contents of my /boot/grub/grub.conf: . . # grub.conf generated by anaconda # # Note that you do not have to rerun grub after making changes to this file # NOTICE: You have a /boot partition. This means that # all kernel and initrd paths are relative to /boot/, eg. # root (hd0,0) # kernel /vmlinuz-version ro root=/dev/mapper/vg_c3po-lv_root # initrd /initrd-[generic-]version.img #boot=/dev/sdb default=0 timeout=5 splashimage=(hd0,0)/grub/splash.xpm.gz hiddenmenu title Scientific Linux (2.6.32-71.29.1.el6.x86_64) root (hd0,0) kernel /vmlinuz-2.6.32-71.29.1.el6.x86_64 ro root=/dev/mapper/vg_c3po-lv_root rd_LVM_LV=vg_c3po/lv_root rd_LVM_LV=vg_c3po/lv_swap rd_NO_LUKS rd_NO_MD rd_NO_DM LANG=en_US.UTF-8 SYSFONT=latarcyrheb-sun16 KEYBOARDTYPE=pc KEYTABLE=us crashkernel=128M rhgb quiet initrd /initramfs-2.6.32-71.29.1.el6.x86_64.img . . I simply don't know exactly how to write the entry, I'll be happy If someone can point me in the right direction. Thanks in advance.
