Good call Trouble, however, he would not be able to delete that E: partition even if he tried, Windows or any 3rd party partitioning tool would not let him delete it as it is a "System" drive/partition, as you caught. Link Removed - Invalid URL
It does seem very strange that they would put a "System Reserve" partition after the OS and to leave 11Gb's at the end of the drive and a 1Tb drive unallocated. Link Removed - Invalid URL
If it were me, I'd take it back and have them do it right or they can keep it. Link Removed - Invalid URL
