accidentally uninstalled kernel

evil_empire · 10-02-2009, 10:47 AM

I was removing the latest two kernels installed because of some issues with compiz and stuffs. And I accidentally removed the only kernel left too. Now, grub has only one entry for Windows. I used "yum remove kernel-.....". Now, I'm stuck, I don't want to re-install the system. It FC11 using LVM. Is there any way I can install re-install the kernel only. What I'm thinking of is copying the kernel image from a live fc11 or installing via rpm on maintenance mode if its possible.

you should be able to boot to rescue media (F11 install DVD), mount the on-disk filesystems, chroot /mnt/sysimage, and then install the kernel from there (either off the install DVD or pull it from a network location).

Thats exactly what I did, installed the kernel rpm from the install DVD while in rescue mode. They system boots fine but the X is broken. Probably a lot of other packages were uninstalled when I yum removed the stock kernel. I'll try to do a yum install in rescue mode. Lets hope, it'll install the other packages too.

If it boots "normally" off the installed OS and you have networking, you should be able to use yum groupinstall what you need fairly easily... I hope.

Code:

yum groupinstall "GNOME Desktop Environment" "Graphical Internet" "Sound and Video" \
     "Window Managers" "X Window System" "Office/Productivity" "Base"

yum grouplist should show you available names to use and the above are just some I picked.

Thanks a bunch. Thats what I was thinking of doing next. I've got to find a LAN cable to connect to the router. For some reason I don't seem to be able to connect to the Wireless while on text mode.

Network manager is maybe disabled. Or you removed kernel drivers for wireless.

Theres no network manager for text mode.The drivers are fine. I'll try with wpa_supplicant or with an ethernet cable.

what about madwifi? I recommend you reinstall it, to add kernel modules to new kernel.

My chip doesn't use madwifi. I use ath9k. Its working fine. Its always a nightmare to get connected to wifi in text mode. ath9k has a lot of bugs. I've already fixed the system using a LAN cable.
