I have an Ubuntu 12.04 / Windows 7 dual boot. After installing Ubuntu my computer reboots straight to Windows. There is no option to boot Ubuntu.
- OS: Windows 7 Home Premium
- CPU: Intel i5 2500k
- mobo: ASUS P8Z68-V Pro
- GPU: GeForce GTX 570
- SSD: Corsair 120GB (Windows 7)
- HDD: WD 1TB
I select the USB drive in the BIOS and boot to it and choose install. I select to manually configure partitions, partition the 200 GB of unallocated space on my 1 TB HDD into 16 GB swap file, 30 GB
/ ext4, and 154 GB
I made sure that the bootloader is installed on the Corsair 120GB SSD (where the Windows boot is) and the installation goes smoothly.
When I reboot after the install it runs through the BIOS straight into Windows. I have tried upwards of a dozen times and I have also tried with Linux Mint. I have also redownloaded the ISO and used two different programs to create the live USB.
The installation seems to have gone well, as after the installation I can see the partitions I have created in Windows Device Manager.
I currently run Lubuntu on my laptop, but it is not a dual boot. I'm assuming this is a bootloader issue and I am assuming that inside those partitioned files in my screenshot there is a working Ubuntu 12.04. I just have no way of getting to it.
Update: (copied from comment)
I booted using my Ubuntu live USB and used the Boot-Repair tool suggested in virpara's answer.
Upon opening the tool I saw that it was recognizing my SSD as a removable drive and defaulting to install on the HDD. Once I realized that I was able to force install onto the SSD. My computer can now boot Ubuntu.
