I am trying to install OS X 10.4.6 on an iBook.
I am installing from a DVD copy made by the local apple store.
The "Checking your installation DVD" part completes without errors.
During the install it stops and says:
BomFatalError - cpio read error: bad file format
Install failed: some files for BSD may not have been written correctly
I've tried this several times, always with the same error.
In the Disk Utility - First Aid tab, I tried Verify Disk and Repair disk, both which fail with "Could not unmount disk"
I also tried Verify Disk Permission and Repair Disk Permissions, both of which complete successfully.
Then I tried to erase the disk (1 pass), and it says:
Zero Disk failed with error
Could not unmount disk.
What else can I do?
