How to boot linux kernel without bootloader?

Changing kernel and initrd references?

• 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/sda2 # initrd /initrd-version.img #boot=/dev/sda default=0 timeout=5 splashimage=(hd0,0)/grub/splash.xpm.gz hiddenmenu title Red Hat Enterprise Linux Server (2.6.18-53.el5) root (hd0,0) kernel /vmlinuz-2.6.18-53.el5 ro root=LABEL=/ rhgb initrd /initrd-2.6.18-53.el5.img ^^^^^ this is the grub after bringing it up am trying to refer the kernel and initrd to another folder but i really don't knw how to put it in grub terms i have the place i want to refer it to in another directory, so how do i refer it to the directory .

• Answer:

  The bootloader can only point to files in its root partition. Since you installed it to the /boot partition, it can only read files under the /boot partition. You can point it to, say, /boot/kernels/custom/vmlinuz-2.6.18, but not to /home/user/kernel/vmlinuz.
