´You cannot install Mac OS X on this volume.´ Mac Error

Intel and PowerPC Macs use different native schemes. Where Intel-based Mac systems are compatible with Apple_partition_scheme, PowerPC-based Mac can only be used with GUID_partition_scheme. These incompatibility issues can create data loss situations. Hence to recover the lost data, you need to use Mac Data Recovery utilities.

When a user tries to install Mac OS X on a hard disk that is connected to an Intel-based Mac system, an error message may be encountered as:

"You cannot install Mac OS X on this volume. Mac OS X cannot start up from this volume"

The reason behind the error message is Mac OS X installer. User even fails to select the disk in such cases. It happens because of non-native hard disk partitioning scheme with respect to system processor. Though operating system gets installed on a volume, but the issue is hard disk partitioning scheme. Thus to solve the issue, we need to repartition the hard disk using GUID_partition_scheme.

• Before repartitioning the hard disk, you should backup all data as the data gets lost because of file system loss during the repartitioning process.

In case of a system crash, if backup is not available or some error occurs during

the partitioning process, Data Recovery Mac tools can recover lost data.

• Then, Disk Utility can be used to select the required disk.

• You need to click on the Partition tab and choose required number of partitions from Volume Scheme pop-up menu.

• Next, you should go to Options and choose GUID Partition Scheme from Partition Scheme menu and click OK.

• Click on Partition tab to erase disk data.

• Mac OS X can now be installed with the updated hard disk partitioning scheme.

• The lost data can be restored using backup.

Mac recovery is required if you lose data due to invalid or incomplete backup. Thus, experts suggest verifying media integrity and backup completeness after taking all complete or partial backups. However, in situations of damaged data backup, Data Recovery Mac tools can help to recover all lost data. These are unique tools that can scan affected drive and recover lost data. Mac Recovery software are user-friendly tools which can be easily used.
