Can i reboot an earlier kernel by swapping "vimlinuz.old" with "vmlinuz"?

No need to do anythng as risky as renaming files .. the old kernels are stiil present and selectable from the GRUB menu.

Turn off your PC

Turn on your PC and immediately hit and hold the Shift key .. eventaully you'll be presented with the GRUB menu which looks something like (but not exactly) this:-


Use the up/down arrow keys to select thee one you want to boot (Peppermint with Linux 3.2.0-40-generic) and hit enter to boot into that kernel.

Be aware ..
a) depending on the GRUB version that kernel may be listed under the "Previous Linux Versions" submenu
and
b) do NOT select the 3.2.0-40 kernel line that ends with "(recovery mode)"

Once you managed to boot into the 3.2.0-40 kernel (whilst running that kernel) come back here and post the output from:
Code: [Select]
uname -aso we can check you are indeed booted into the older kernel.

Very cool! I'll get right onto this and we'll see what we see :-)

Linux jairrohm-AO756 3.2.0-40-generic #64-Ubuntu SMP Mon Mar 25 21:22:26 UTC 2013 i686 i686 i386 GNU/Linux

jair-rohm@jairrohm-AO756 ~ $ ls /lib/modules
3.2.0-23-generic  3.2.0-40-generic  3.2.0-77-generic
3.2.0-39-generic  3.2.0-65-generic

looks like a more recent kernel got kinda half installed

What's the output from:
Code: [Select]
apt-cache search 3.2.0-77and do you get any errors at the end of
Code: [Select]
sudo apt-get update

Hi trkkazulu, I see that the outputs you returned are very long.  In future, could you please encapsulate long outputs with the Sp Spoiler function.  This is located in the forum editor, just above the crying  :'( emoticon.  It makes it much easier for people to read and keeps things neat and tidy.  This time I've done this for you.  Thanks in advance ;).
