Increased efficiency in booting a computer uses a process of logging physical-level disk access during a boot cycle for use in creating a boot plan for a subsequent boot. Processing the log from one or more previous boots removes unnecessary reads such as those associated with temporary files and then orders the remaining read accesses based on times of prior read accesses and and by physical location on the disk. Upon boot, data likely to be requested first orders the remaining read accesses based on times of prior read accesses and By taking advantage of disk head and platter characteristics, data is read in sweeps through the disk, reducing overall latency. Requests that are not in cache may be held if the data is already scheduled for retrieval.
