I installed Fedora Core 3 yesterday and after install I downloaded the update packages including the kernel updates. Now during boot, Grub has 3 options instead of 2.
Fedora Core (2.6.10-1.770 FC3)
Fedora Core (2.6.9-1.667)
Windows XP
Do I need the middle one? If I delete it in the grub.conf file will I mess something up or will it just remove it from the bootloader window and leave me with the option to choose between the first and third ones? Does this mean that I actually have 2 full Fedora Core versions installed, and should I uninstall the oldest one? If so, how? If not, why?
The grub.conf file reads as follows:
#boot=/dev/hda
default=2
timeout=5
splashimage=(hd0,1)/grub/splash.xpm.gz
hiddenmenu
title Fedora Core (2.6.10-1.770_FC3)
root (hd0,1)
kernel /vmlinuz-2.6.10-1.770_FC3 ro root=/dev/VolGroup00/LogVol00 rhgb quiet
initrd /initrd-2.6.10-1.770_FC3.img
title Fedora Core (2.6.9-1.667)
root (hd0,1)
kernel /vmlinuz-2.6.9-1.667 ro root=/dev/VolGroup00/LogVol00 rhgb quiet

It just means that you (presumably) have two linux kernels now, not that there are two systems installed.

If you don't want to use the older kernel you can safely comment it out of the grub config file. Just make sure your new kernel boots ok for you and everything works first.

You can delete the listing from the grub file if you really want, but I prefer to just comment it out in case I need to refer back to it at some point in time.

Im not sure what you mean by "comment out". Sorry, I know next to nothing about linux, especially commands.Could you further explain please?

Howzit

It seems that ure kernel has been updated with a new one which is good. U do not have to remove the older kernel just yet, what I suggest is to keep at least 2 versions of your kernel just in case the new one u upgraded to has some problems or compatablites with hardware etc.

What the last poster was saying to coment out was for u to edit the /etc/grub.conf file and place a # in front of the kernel u do not want anymore but if u still new to editing files and learn Linux rather do this at a later stage
