I dont know the exact answer to this question. But stopping an installation
half way through with a hard reboot is never good. If it was me, I would
back up my databases and uninstall SQL Server and Reinstall it from scratch.

No reason to go months down the road and then realize that the DB isnt
perorming optimally because of a bad install.

thanks,
