i have sony laptop, pcg-7181m model. came windows 7 changed os ubuntu.
last night asked me upgrade new version called natty narwhal. had go bed changed sleep timer on laptop 2 hours, time have taken upgrade complete. woke , laptop off, grub menu shows , laptop won't boot.

i tried doing this:
- when machine boots up, press ‘esc’ grub menu
- select 1 of “recovery mode” options. boot single-user root prompt.
- run “sudo fdisk /dev/sda” (this assumes hard drive @ sda)
- type “p” see hard drive partition labeled “linux swap”. in case partition /dev/sda5. type “q” exist fdisk.
- type these commands:


sudo swapoff /dev/sda5
(use whatever partition labeled “linux swap” in fdisk. me, /dev/sda5)
sudo mkswap /dev/sda5
sudo update-initramfs -u


however, says swapoff failed: invalid argument.


know absolutely nothing sudo command (or else linux matter) , appreciate help!
