Ubuntu13.10 64 bit installed alongside windows 7 32bit doesn't boot
- by alone
I have installed Ubuntu 64-bit alongside windows 7 32-bit. (Windows installed first.)
The installation was successful, but when I restart it just goes directly to windows 7 without any sign of existence of Ubuntu.
I'm a beginner who just wanted to get familiar with Ubuntu, but now I'm disappointed with it. Someone told me the not booting problem is related to EFI, but now I'm scared to play with this boot stuff because my information might be totally lost.
How can I fix this boot problem and get to Ubuntu?
