hi, i tried compiling linux 2.6.25.4 in my VL5.8 (guest OS in virtual box)

i have compiled the 2.6.25.4 kernel already and have loaded it in grub for a test .. BUT since im getting a problem I HAVE tried turning back to the original kernel.. BUT WHY even though i have commented out the test kernel in menu.lst still the new kernel is sitll loading ?? (even in the start up boot)

details :


#TEST KERNEL

#title Test Kernel
# root (hd0, 4)
# kernel /boot/bzImage-2.6.25.4 root=/dev/hda5 ro vga=normal
# initrd /boot/initrd.img-2.6.25.4


BUT when i check uname -a

Linux vector.linux.net 2.6.25.4


i just wanted to get back to my previous kernel .. but the problem is .. even though I get it back to the original settings.. still the new one is being booted
