I'm trying to install Ubuntu 12.04.3 on my Sony Vaio with Windows 8 pre-installed. I want to have a dual boot setup. If boot is set to UEFI mode, I cannot boot from the LiveCD. So I set it to Legacy mode and I could boot from the Live CD and install it. The setup went fine. I could allocate 100GB for Ubuntu. Eventually I had to restart after installation. Now it happens that:
- If boot to Legacy mode, an error message appears when I switch on the notebook. The error says
Operationg system not found. So neither can I boot Windows 8 nor Ubuntu.
- If boot is in UEFI mode, Windows 8 boots normally. There is no request to choose between Windows or Ubuntu
If I try to install Ubuntu again, it recognizes the installation. I tried to reinstall over it, but the system still behaves as described above
What I should do to have my dual boot working well with both Windows and Ubuntu?
Note: Ubuntu works perfectly from the LiveCD
