We installed Windows 10 on a few different machines and the System Reserved partition varies in size. Sometimes, 50mb, 100mb, and 500mb. Smaller drives sometimes have a larger System Reserved partitions than larger drives. We use the same installation flash drive each time. We've run into problems when the partition was only 50mb and we had to increase the size to be able to update Windows. Is there a way to change this while installing Windows 10?
