Macbook Pro unable to reinstall from Time Machine
The reinstallation was hung with following message:
Preparing to restore "Machintosh HD"...
After a few hours, still the same. Hard reboot later found that no modification in old OS, even requested erasing the disk.
Formatted disk before retry, got same issue.
The possible issue could be that the Mac can not reach Time Machine backup, because there is no blinking of the backup USB disk.
Install fresh OS, then start performing OS transfer from Time Machine backup.
