I have a HP G7000 laptop.

I updated/upgraded from 13.04 to 13.10, after the software updater recommended I upgrade.

I have duel booting system with Windows Vista. The system was working for the past two days, but I start getting the errors below, after selecting Ubuntu in Grub Menu on startup and at the splash screen it says "Press S to Skip or M for manual configuration"

Pressing S gives a black screen and m takes you the errors below.

Windows boots and works fine after selection in the Grub Menu.

[   15.235703] EXT3-fs (sda5): error: unrecognized mount option "discard" or missing value.

[   16.788072] [drm:intel_pipe_config_compare] *ERROR* mismatch in adjusted_mode flags [expected 2, found 0]

[   20.980076] [drm:intel_pipe_config_compare] *ERROR* mismatch in adjusted_mode flags [expected 2, found 0]


Root filesystem Check failed

Tried boot-repair using the LiveCD method, no luck. System still gives above error. (you can view the boot-repair log here http://paste.ubuntu.com/6287287)

When I use the liveCD for 13.04 or 13.10 however, my hard disk is recognized and I can read the files. Why is it that the installation on the hard disk has stopped working and does not recognize my / ? What do the above errors mean and how can i solve them?

There was no power failure before, during or after the update/upgrade process from 13.04 to 13.10.

I now would like to go back to 13.04 without reinstalling afresh?

Any help will be appreciated. Thanks.
