This is a unique problem. The GPT has two partitions not described in the MBR. And the MBR has two partitions not described in the GPT. I&#x27;d use gdisk to fix this. I&#x27;m not sure what message it&#x27;ll tell you when you point it to this disk, or what options it&#x27;ll give. But what I&#x27;d do if it&#x27;s an option is use the GPT, not the MBR. And then use the p command to "print" the gpt to see if it does in fact show just two partitions, the two listed by the gpt command. If so then use n to create a new partition. The start sector is the one listed for MBR 3, 115644416. To tell it what the last sector is, use + and then the size value from the MBR, so for this entry it&#x27;s +204800. The type code should be set to 0700 rather than the default of AF00. Repeat for the fourth partition.Once that&#x27;s done, you&#x27;ll go to the recovery menu with command r, then use command h to create a new hybrid MBR. Type in 3 4 for the partitions to add. EFI GPT (0xEE) partition first in MBR is yes. When asked for MBR hex code, accept the default, it should be 07 if you set it correctly when creating the new partitions earlier. I have no way of knowing which one should be marked as bootable; currently you have the 3rd one marked bootable. Only one should be marked bootable.

Chris, you are like the guru on this on the internet. I&#x27;ve seen your posts everywhere. I am in dire need of help.

Hi Chris,Thank you for the information supplied. Forgive me for being a bit daft here but what is the 1st thing I should do?I I had a look at Disk Utility and currently it shows only one partition or am I meant to be doing something else?Thanks again

Yeah you&#x27;ll need to use gdisk (a.k.a. GPT fdisk) to fix this, it is a command line only program but is used in an interactive mode (text menus and help). Disk Utility can&#x27;t fix this. There are two relevant bits of documentation on gdisk, here and here.
