Ubuntu – Error “fixing recursive fault but reboot is needed”


I am trying to install Ubuntu for the first time.

Version = 11.04 Hardware = Acer Travelmate 4050

I can boot from USB or CD and it loads fine.

I have installed and reinstalled several times from both USB and CD and it completes correctly.

However, when I boot from the HDD I get the above error
I don't see any errors like "kernel panic" mentioned elsewhere.

It happens whether I boot with AC adapter in or out and also with adapter in but battery out.

Not sure how to get further info to help with diagnosis

Here are a few things you can try - edit into your question with results if any either does or doesn't work.

  • Some more detail info about your laptop might give some advice on what to try next. Booting from Live CD/USB...

    ...Open a terminal and type





    sudo lshw

    Copy and paste the results into your question.

  • Try turning off both power management and graphics driver loading during booting. To do this, edit /etc/default/grub, find the GRUB_CMDLINE_LINUX_DEFAULT= line, and add acpi=off nomodeset xforcevesa. That is, the new line will probably look like:

    GRUB_CMDLINE_LINUX_DEFAULT="quiet splash acpi=off nomodeset xforcevesa"
  • After that, run:

    sudo update-grub

    You can use this AU question to guide you through these two steps.

  • Then enter your BIOS settings - have a look at the following bios settings and try toggling the values one at a time and see if you can boot (assuming these options exist):

    a. Legacy USB Support
    b. Disk Management/SATA/IDE Compatability Mode
