Failed Mac Install for Dual Boot...Computer Dead? Please Help.
Joined forum because I desperately need some help. I wanted to install linux (64 Cinnamon) mint on an old mac mini and went the USB stick route to try and do this. I followed a procedure that seems fairly standard to use terminal to create a bootable image. Convert file to .img and then dd using
It said the drive was not recognizable, but I clicked ignore and then ejected it. I thought I'd try it anyway. I had installed rEFIt on my mac and I rebooted the mac with the drive in it.(Before this I resized the Mac OS X drive leaving ~50GB of free space for linux. Holding alt/option gave me to usb drives both called refit and a HD labeled refit. I selected the first usb which brought up a black screen with GNU GRUB version2.00("somethingubuntu"). This had the option to use the arrow keys to select test memory some other stuff and start linux mint 16. I selected this one and it just went to a black screen. I rebooted and tried again selecting the same thing and this time it seemed to start to load linux mint. I then clicked install when I got to the desktop and selected install alongside Mac OS X. I went to bed and woke up with it prompting me to restart. I clicked restart and it froze. Waited ~45 min and it did nothing so I held down the power button.
sudo dd if=/path/to/downloaded.img of=/dev/rdiskN bs=1m
Rebooting takes me to a black screen similar to the prior one I got with GNU GRUB version 2.00-19ubuntu2 at the top. This time the options to select are Linux Mint16, Linux Mint 16 -- recovery mode, Mac OS X (32-bit), and Mac OS X (64-bit). Selecting recovery mode cycles through some code and freezes. Slecting Mac OS X does something similar
Holding down alt/option at boot now does nothing, just takes me to the mentioned black screen. Holding down 'c' with an inserted OS X disc takes me to the black screen as well.
I really need help with this as I have no idea what to do now it doesn't seem like it will let me boot from anything. It says I can press c for a command-line, but I don't know what I could enter to exit that black screen or successfully boot linux. If possible I would like to preserve the old Mac partition because it has some photos on it and I didn't back it up (genius), but at the least I want this to be useable again.
Thanks so much, I greatly appreciate any help, rather worried right now!
TL;DR: Tried to install linux on usb to be able to dual boot with OS X. It failed and now computer only boots to black screen that does nothing when I select its options. Shi!#ing self.
