    As if nothing happened

    Hi All,
    I have just run through what appeared to be a successful installation, with absolutely no errors. However, as soon as the PC restarted after the installation was completed, it booted straight into Win7 without any OS selection prompt screen or anything. There are no new screens between the moment I hit the power on button and the moment I see the Win7 logo...

    Any help will be much appreciated!

    I have a laptop: ASUS 1215B, AMD-E350 processor, 8GB ram

    Check if you have linux partitions on the disk.

    Boot into live mode with the cd and in terminal try:
    Code:
    sudo fdisk -l
    sudo parted /dev/sda print
    Maybe just the grub2 bootloader didn't install. If that is the case, you can add only grub2, no need for full reinstall.
    Darko.

    OK, the linux partitions are there.

    Again from live mode in terminal, try this:
    Code:
    sudo mount /dev/sda6 /mnt
    sudo grub-install --root-directory=/mnt /dev/sda
    Restart without the cd and see if it helped. If not, there is a longer procedure to run, this is the shorter version first.
    Darko.

    Re: As if nothing happened

    Restarting now, incase you are interested, the output from the commands you suggested was:

    Code:
    ubuntu@ubuntu:~$ sudo mount /dev/sda6 /mnt
    ubuntu@ubuntu:~$ sudo grub-install --root-directory=/mnt /dev/sda
    /usr/sbin/grub-setup: warn: Sector 48 is already in use by FlexNet; avoiding it.  This software may cause boot or other problems in future.  Please ask its authors not to store data in the boot track.
    Installation finished. No error reported.
    Thanks!

    All is great! Thanks a lot for your help and support. I finally get the GRUB screen and I can choose OS.

    Thank you very much for your quick replies at this time of night!

    Re: As if nothing happened

    Ah, the Flexnet message. It probably won't work.

    You might need to use the boot-repair. You can do it from live mode too. Full instructions are here:
    https://help.ubuntu.com/community/Boot-Repair

    I am not sure if the recommended repair can help, try that first.

    If the recommended repair doesn't work, try it again but in the Advanced options, in the Grub options tab select the check box Reset extra space after MBR. If you look carefully in the instructions, in the screenshots about the advanced options, it mentions it solves the Flexnet error.

    EDIT: Oops, it did work. Great. Didn't know simple grub2 reinstall can solve the Flexnet too. Enjoy your ubuntu now.
    Darko.

    Grub version 1.99 takes the 'Flexnet' problems into account. When it finds something written in the area to which it normally writes it adapts and records the information elsewhere.

    +1 to enjoying Ubuntu.
