I have a notebook Stream x 360 came with a free upgrade to windows 10 was never able to upgrade always said not enough space and now i need windows 10 and it still says not enough space and wants to charge me or sell me a new pc. I cannot afford either.
Don't worry as I'll be glad to help, I have a few troubleshooting steps we could try to fix the issue:
Double-click the Setup.exe file to launch the Windows 10 installation from the USB flash drive. Select the Keep personal files and apps option to only update your system. If you get the "Windows needs more space" option, click the Choose another drive or attach an external drive with 10GB available link. ... Click Install.
