Ubuntu – Need USB drive to boot aspire one into Ubuntu

12.04aspire-onebootreboot

I just installed 12.04 LTS onto my Acer Aspire One from a USB thumbdrive, and I cannot reboot unless I boot from the USB drive. If I have the USB drive plugged in, it boots, and it looks like the system is running of the HDD (/ is mounted from there, the USB drive is /media/PENDRIVE, everything works fine when I unmount it, etc).

If I reboot with no USB drive mounted, I just get a flashing cursor. It looks like a misconfigured boot loader. The Terminal tells me that grub is not installed … so just how does Ubuntu boot these days, and how can I make the HDD bootable?

Possibly you have installed grub in the usb not in hard disk.

To install grub in hard disk,

  1. Boot using ubuntu live usb,

  2. install boot-repair by using the following commands.

    sudo add-apt-repository ppa:yannubuntu/boot-repair && sudo apt-get update

    sudo apt-get install -y boot-repair && boot-repair

  3. Launch boot-repair from dash and perform a repair. If it doesn't fix remember the url notified by boot-repair tool (like paste.ubuntu.com/) and post the url.
