 Posted: Mon Sep 05, 2005 1:48 am Post subject: How do you install a new kernel? |
 |
|
I followed the handbook installation, and had something that booted. Then I recompiled the kernel, and copied the image to the /boot folder, replacing the previous image (using the same filename).
Is there anything else I need to do? After rebooting, I get a "Error 15: File not found". I would expect Grub to look for the same file. |

Did you use genkernel either time, by chance?
Boot KNOPPIX or some other LiveCD that facilitates cut 'n paste, mount your / and/or /boot partition somewhere, cd to the boot directory and paste the exact output of the following commands, wrapped with [ code ] tags:
| Code: | ls -alR .
cat grub/grub.conf |

Thank you Dlareh!! I was able to resolve the problem from that information. The image filename was mismatched  .
I think what happened was at one point I wasn't sure whether I needed to put the image on the root "/" of the boot partition (/dev/hda1), or on the "/boot" folder of the root partition (/dev/hda3). The image was named something like "kernel-2.6.12-gentoo-r6" in one place, and "kernel-gentoo-2.6.12-r6" in the other place. |

I suggest you to not overwrite the old kernel before new starts, just write a new section with your new kernel specification and run grub-install <install-device>, i.e. in most common case grub-install /dev/hda. Look at grub-install specifications also.

| Agree with previous poster although I don't think you need to run grub-install everytime you add a new spec. The only time you need to run grub-install is when you need to reinstall the boot sector. With lilo you need to run lilo when you add a new specification, and that is one of my main reasons for using grub. |

Right, there is no reason to re-run grub-install
Just to give you some idea of the kind of crap that can accumulate in /boot when you use different kernel names:
| Code: | $ ls /boot
System.map
boot

Hmm. If that's true, grub is even nicer than I expected  . I'm probably too used to lilo, and didn't even think of the possibility that the grub-install is not needed after every update. Will check it as soon as i get home.
And big thanks!
