"Missing Operating System"

rated 0 times [ 0] [ 0] / answers: 1 / hits: 983 / 1 Year ago, sat, february 4, 2023, 7:11:45

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.

Ok..U have 1 harddisk (/dev/sda) and this harddisk is partitioned in 2 partions: /dev/sda1 & /dev/sda2. There is also unallocated space present. OSX is probably located in /sda2 because I can see an hfs+ filesystem on sda2. Ubuntu needs another filesystem like ext4 (there are others). But you can't install Ubuntu on an hfs+ filesystem. So..the best you can do is install Ubuntu in the unallocated space. The installer will see this space and offers you the possibiltiy to use this space. The installer will create all the partions you need. The bootloader should be pointed at /dev/sda1 ( I think, because I have no knowledge about OSX)
