I wanted to have dual-boot setup on my MacBook Pro. So after searching for a bit, I found a couple of sites that offered a step-by-step explanation on how to do it using rEFInd.
I successfully installed it – I got the rEFInd startup screen and everything. The problem is that when I selected the USB drive I wanted to install from. It always got stuck on a black screen saying
No bootable device — insert boot disk and press any key
But that’s a different problem. After not being successful in booting from the USB drive, I had a “brilliant” idea.
I could take the same image I flashed onto the USB drive and try to do the same but on the partition I had prepared for Linux, so then maybe rEFInd will be able to boot if it’s on the hard drive. So I did the following:
sudo dd if=/path/to/downloaded.img of=/dev/rdiskN bs=1m
With diskN being the partition on the hard drive, then restarted. And after that, the MacBook Pro never came back. It makes the chime sound, and that’s it. Also, I notice that Caps Lock and Eject keys don’t work, as I tried booting from a Linux CD and now I cannot eject it.
Startup key combinations don’t work, so using the recovery partition is not an option. It only turns on, makes the chime sound and get’s stuck on a white or grayish screen.
Any advice on how to solve this or ideas on what could have happened?

After reading the comments I would try to use Internet Recovery (Command + Option + R) and see if that works.
