I am unable to wipe my hard drive and install new OS X as the resource is busy. I would imagine this is because I have Recovery open on this disk and that's why it is busy.
I've tried:
diskutil unmount disk0
hdiutil detach disk0
My disk parts look like this:
/dev/disk0
0: GUID_partition_scheme *250.1GB disk0
1: EFI EFI 209.7MB disk0s1
2: Apple HFS Macintosh Hard Drive 249.2GB disk0s2
3: Apple_Boot Recovery HD 650.0MB disk0s3
/dev/disk1
0: Apple_partition_scheme *1.3GB disk1
1: Apple_partiton_map 30.7KB disk1s1
2: Apple_HFS OS X Base System 1.3GB disk1s2
I am also unable to install from appstore as this Macbook 2010 Unibody does not have an operating system on it.
I am stuck in Recovery HD and wonder what my options to get running again are.
diskutil eject disk0
?
