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:
