Hi Katatawnic, Check the directory /boot/ for the files initrd.img-2.6.31-14-generic and vmlinuz-2.6.31-14-generic. If the files are present go further with the steps below.
Copy the original menu.lst to menu.backup.lst. Open the file menu.lst inside /boot/grub/ in a texteditor. Add the following rules under the rows that look like these ones: title Ubuntu 9.10, kernel 2.6.31-14-generic uuid 6e08943a-8da4-4b93-8d5b-440e954dba61 kernel /boot/vmlinuz-2.6.31-14-generic root=UUID=6e08943a-8da4-4b93-8d5b-440e954dba61 ro vga=795 splash quiet initrd /boot/initrd.img-2.6.31-14-generic quiet title Ubuntu 9.10, kernel 2.6.31-14-generic (recovery mode) uuid 6e08943a-8da4-4b93-8d5b-440e954dba61 kernel /boot/vmlinuz-2.6.31-14-generic root=UUID=6e08943a-8da4-4b93-8d5b-440e954dba61 ro single initrd /boot/initrd.img-2.6.31-14-generic Change the UUID with the UUID you see in the original kernel settings in this file. Almost at the bottom of the file you'll see a similar bunch of code. Change in these rows the kernel link number to 2.6.31-14. Now you're ready, Save the file and reboot... *If the reboot failes start the Ubuntu live CD and rename the copied menu.lst from menu.backup.lst to menu.lst and try it again.* * * *good luck!* Peter 2009/11/3 Katatawnic <[email protected]> > How do I switch kernels?
