View Full Version : [ubuntu] Unable to dual boot between Ubuntu and Windows 7

September 23rd, 2012, 10:28 AM
Sorry, I have double posted the same topic, But it was in the wrong section.

I downloaded a copy of Ubuntu 64-bit OS iso images and booted up in the thumb drive. I then created a live USB using Unetbootin. I then booted the live USB up in non EFI mode and installed Ubuntu in a separate partition so that I could have 2 Operating System on my computer.

But I could not get the dual boot option. And then again after following up some forum posts from this website, I tried using boot-repair and it installed GRUB 2.

Here's what the instruction said after the boot-repair completed its task.

Boot successfully repaired.

Please write on a paper the following URL:

In case you still experience boot problem, indicate this URL to:
boot.repair@gmail.com or to your favorite support forum.

You can now reboot your computer.
Please do not forget to make your BIOS boot on sda1/EFI/ubuntu/grubx64.efi file!

The boot files of [Ubuntu 12.04.1 LTS] are far from the start of the disk. Your BIOS may not detect them. You may want to retry after creating a /boot partition (EXT4, >200MB, start of the disk). This can be performed via tools such as gParted. Then select this partition via the [Separate /boot partition:] option of [Boot Repair]. (https://help.ubuntu.com/community/BootPartition)
I then rebooted the system and I could get an option booting up Ubuntu and Windows 7 alongside with it, but the problem is that when choosing Ubuntu it does not seem to do anything. The screen just goes blank.

The grub configuration file is attached within this post if it helps.

Please help. I am new to linux but I am eager to learn it.
