    Can't Update System Reserved Partition

    Received this message whilst trying to upgrade my Acer Laptop from Windows 7 Home Premium SP1 256 GB SSD to Windows 10 Home.

    I've previously upgraded my Desktop from Windows 7 Pro SP1 256 GB SSD to Windows 10 Pro & subsequently performed a clean install with no problem; Being a home built PC, I don't have any reserved partitions on the SSD.

    Most, if not all, pre-installed operating system on 'shop bought' PCs/Laptops come with system reserved partitions so I wouldn't have thought this to be a problem, but obviously, for some reason, it is!

    Any ideas greatly welcomed.

    I've found the solution - see Windows 10 will not upgrade (partition issue) - Windows 10 Forums

    Reserved System Partition was 100MB.

    Windows 10 requires between 400MB & 500MB - used AOMEI Partition Assistant to resize Windows by 350MB & then increase size of Reserved System Partition to 450MB. After several anxious moments when Windows shut down into DOS environment to perform the actions, it successfully rebooted back into Windows 7.

    Upgrade now proceeding & now fully working.
