How to dual boot Windows 7 x64 and Ubuntu 13.04 x64 as BIOS, not EFI

rated 0 times [ 4] [ 0] / answers: 1 / hits: 23459 / 2 Years ago, fri, february 25, 2022, 10:53:46

I wanted to dual boot Windows 7 64-bit and Ubuntu 13.04 (Raring Ringtail) 64-bit, but when I installed it, it didn't boot. Only Windows was booting. I installed Ubuntu with a " / " of 50 GB and a "swap" partition of 4 GB. Could it be that it doesn't work, because I'm on BIOS mode, and that my disk is MBR, not GPT?

My laptop doesn't have an option to change boot mode to UEFI so as much as possible, I'd stick to MBR :(

System

Acer Aspire 4755G

Intel i5-2450M 2.5 GHz - 3.1 GHz

Nvidia [GeForce GT540M][7] 2 GB

4 GB RAM DDR3

Here is your solution

There is a very easy and interactive way to fix the GRUB problem. Using this method it will start reading all your boot partitions and also you will be able to use any operating system. All operating systems installed in your computer will be displayed in the GRUB menu.

You have to follow these very simple steps...

Boot from a live CD or your bootable USB, and select 'Try Ubuntu'.

Install boot-repair (a good program to fix GRUB):

sudo add-apt-repository ppa:yannubuntu/boot-repair

sudo apt-get update

sudo apt-get install boot-repair

Run boot-repair from your system or type: (boot-repair &)

When started, select option Recommended Repair from the two options:

Recommended Repair & Advanced Options.

Follow the very easy onscreen instruction. It will build/fix your GRUB installation...

Restarting your system will display both options to boot from Ubuntu and Windows.
