I'm tring to install Ubuntu 13.04 on my PC desktop but when i restart my PC, it always starts Windows 7, without asking me which OS would i like to run. I've got 3 HDD on my PC:

1: 200 GB with Win7

2: 500 GB partitioned with 4 GB of Swap, 150 GB of /home and the others GB of root (/)

3: 2 TB of various data.

I think the bootloader is on sda1, and during the installation of Ubuntu 13.04 I can't install a bootloader on that partition (fatal error). What should i do?

Here my log of fdisk:

ubuntu@ubuntu:~$ sudo fdisk -l

You should use boot-repair

2 open a terminal and type

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



sudo apt-get update



sudo apt-get install boot-repair boot-sav

2b Click the ubuntu icon (top left) and search boot then run the application called Boot-repair

3 follow all instructions and enter all commands when prompted

After this reboot an you will see the grub menu listing your operating systems.
