I've been trying to dual boot Ubuntu on my Macbook pro with an ISO disk.
I installed the ISO onto the disk successfully, partitioned my main drive and set as FAT32 format, I restarted the computer with the disk in the drive and it launched and walked me through the installation process and then it said "please restart" which I did. I booted from my windows partition and it said "missing operating system" but I know everything got installed so what is the issue? I've tried twice and I'm not sure what's causing this error, any help would be appreciated.
Oh and each time I installed it, I installed it to "/dev/sda3" and the next time I installed it to "/dev/sda4" there was also an option to save to "/dev/sda1" should I have done that? Do I need to have a swap partition in order to boot linux? I only created one partition and that was for the OS.
