Hi sorry i should have been more specific,
Model - VIN, MacBook Pro (13-inch Mid 2010)
Internet recovery mode / standard recovery mode
- disk utility
erase disk (error failed to unmount disk)
First aid (successful 'problems were found with the partition map which might prevent booting')
erase disk ( error failed to unmount disk)
First aid (updating boot support partitions for the volume as required. unable to unmount volume for repair)
- osx install (not enough space on disk)
note
- during recovery mode during disk utility it takes a decent amount of time (5mins ish) to load the disks.
- when erasing the drive i'm selecting the option, Format - OS X Extended (journaled) Scheme (GUID Partition Map)
- i also can't seem to start the macbook in safe mode.
Bootable USB
I thought using a bootable usb would help. I have no idea which OS the macbook has so i created an el capitan bootable usb.
