Checked system and qualified for upgrade. When attempted gave error "couldn't update the system reserved partition". Searched on-line for solution. Downloaded a Tool Partition wizard and attempted to follow directions. Success in moving bar and now have 300 in unallocated ... was not able to complete the instructions thru disk management in my computer. Now I don't know what to do. I tried the Windows 10 upgrade again and it failed with same error message. Tech support for the site where I downloaded the tool suggested I delete the 128 MG partition marked OTHER RESERVED. I'm afraid of what that might do. I've got help from this site before on other issues. Thanks for help.
