Resolved Apple Partition Conundrum

[tesla735]

I am sorry if this is the wrong thread, I am new to this forum.

My computer has been through a lot recently, but here is a quick summary of events.

1) One day it randomly decides not to boot
2) I try to boot from a usb stick
3) That fails
4) I take it to apple
5) They replace one of the hard drive cables, which seems to fix the problem
6) My linux partition is gone (they may have deleted it 😡)
6) I inspect my partitions and find this:

/dev/disk0
   #:                       TYPE NAME                    SIZE       IDENTIFIER
   0:      GUID_partition_scheme                        *320.1 GB   disk0
   1:                        EFI                         209.7 MB   disk0s1
   2:                  Apple_HFS Macintosh HD            149.1 GB   disk0s2
   3:                 Apple_Boot Recovery HD             650.0 MB   disk0s3
   4:                  Apple_HFS Recovery HD             650.0 MB   disk0s4
   5:       Microsoft Basic Data                         124.9 GB   disk0s5
   6:                 Linux Swap                         4.2 GB     disk0s6
/dev/disk1
   #:                       TYPE NAME                    SIZE       IDENTIFIER
   0:     Apple_partition_scheme                        *18.8 MB    disk1
   1:        Apple_partition_map                         32.3 KB    disk1s1
   2:                  Apple_HFS Flash Player            18.7 MB    disk1s2

So it appears that linux is still there but it will not appear in disk utility.
Here is what my disk utility screen appears like:

I am running OSX 10.8.5 on a 13" 2011 macbook pro
I am very confused. I want to be able to access my linux data. When I boot and hold down option only my main os and recovery hd show up. I seem to have to partition schemes.

All I want is to be able to get back to the way it was before I sent it in to get "fixed".

What I want to know is: Should I delete /dev/disk1 and if so how?

Thanks in advance

/dev/disk1 is a disk image that is mounted by Adobe's auto updater for Flash player. When you restart your computer, it'll unmount and stay away until the next Flash update is downloaded and mounted to be installed.

Thank you

Thank you very much. Rebooting did fix that but how do I boot from my linux partition? When I reboot and hold down option only my osx partition and the recovery one show up. I know it is there but I cannot access it. It is also not in the finder sidebar.

I'm not overly familiar with Linux on Macs, but maybe the bootloader is missing or not correct? I have no idea. You may want to wait for someone more experienced with it to give you some suggestions.

Thanks again intell

Thanks again for the quick reply! I will continue waiting for more from other sources.

Thanks again for the quick reply! I will continue waiting for more from other sources.

I think what happened is you installed a boot manager of some sort when you installed Linux and when Apple reinstalled OS X, that wiped the boot manager.

What you need to do is reinstall an EFI compatible boot manager like rEFInd.

Solved

Thanks, that did fix it. I feel like an idiot now though 🙁
