Have been trying for 2 weeks to upgrade my 1+ year old laptop to Win 10 - it runs the tests, acts like it is installing, etc. but after the blue screen announcing the update downloads, it boots one more time and freezes on the TOSHIBA splash screen - have left it sit overnight but no indications of HD activity. Was able to update two OLDER laptops with ease but not this one (L75-B7270). When I finally get to an error screen, one of the options is to loan another OS but when I goto that screen it says I have Win 10 loaded 5 times??? I have tried the direct download and loading from a burned ISO disk - same results; have tried disabling the UPDATER prior to starting (net stop WUauserv) - nothing - HELP! After each failed attempt I have rolled the system back to the original OS and tried again!
