Unable to run Ubuntu 12.04 without USB flash drive

Question

Yesterday I installed Ubuntu from a USB flash drive. Now, when I turn on my notebook, it displays only _. When insert the USB drive it's ok.

I tried changing BIOS settings: some booting options, but it didn't help.

What should I do to make it possible to run without the USB flash drive?

Thanks in advance :)

Thanks but it didn't work properly. Boot Repair wrote "EFI detected. Please check the options." I don't know if it's important..after command sudo fdisk /dev/sda it answered: Command (m for help): m Command action a toggle a bootable flag b edit bsd disklabel c toggle the dos compatibility flag d delete a partition l list known partition types m print this menu n add a new partition o create a new empty DOS partition table p print the partition table q quit without saving changes s create a new empty Sun disklabel t change a partition's system id u change display/entry units v verify the partition table w write table to disk and exit x extra functionality (experts only)

Command (m for help):

So I chose sda. Then it said something like if any problems- http://paste.ubuntu.com/1027567/ or boot.repair@gmail.com or my favourite discuss forum. Then: You can now reboot your computer. Please do not forget to make your BIOS boot on sda disk! What has happened? what should I do? it again wasn't able to run without USB. Thank you

Answer 1

It sounds like you have the MBR installed onti the wrong disk.

Boot into your installation (with the USB stick in place).

Once you have done that, connect to the internet and open a terminal.

Enter the following lines seperatly into the terminal:

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

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

Once these actions have completed (following the in-terminal instructions) the "Boot Repair" application will open.

In this windows click "Advanced options"

Then click "GRUB location"

Choose "Place GRUB into:

In the drop down box opposite the last selection choose your HDD rather than your USB drive. On my computer my HDD is named "sda" and the USB drive "sdb" but these may be the other way around for you, or even different things if you have an unusual drive set up.

I would suggest checking which is which is which by running this command in the terminal:

sudo fdisk /dev/sda

Here you will be able to see the size of each disk, and presuming they are not of equal size you will then be able to determine which is which.

Once you know the identity of each disk, choose your HDD for GRUB to be placed onto.

Then hit "Apply" at the bottom and wait for everything to complete.

Restart you computer and you should be able to boot without the USB drive.

If this does not work, or you run into any problems let me know in the comments below.

Hope this helps.

Try the "ATA disk" option of Boot-Repair: http://ubuntuforums.org/showthread.php?t=1998257
