Due to my inspiron15 Dell laptop running extremely slow, I did a factory reset to original factory settings. It worked fine and the laptop came with Windows 8.
I decided to upgrade to Windows 10 using the free one still available from Microsoft for people who use disability functions (my mum uses magnifications). However, when turning on it gets stuck on the Dell Logo page with no bar underneath. I have attempted another factory restore as I have managed to get it to run automatic repair but it says that the partition has changed and there is no restore point to work from and won't let me continue.
Can you please suggest what I may do to fix this problem?
