I was trying to upgrade to windows 10 from windows 7 ultimate. But when the setup completes installing windows 10 and it restarts nothing happens and my previous window 7 starts again. Like nothing happened. Neither any drive space is eaten up after the install.
I know if i clean install through booting iso or usb i won't find such problem but i don't want to lose the data on it just want to upgrade. I'm installing it through creation tool.
I also tried just upgrading it through usb through boot but it said to do it form windows by setup when i did that this problem comes up.
Also really don't know what's the reason of this but I think the reason might be that there are two windows already installed the other is also windows 7 when laptop boots up it asks to choose an operating system. The other doesn't work and i can't delete it from the other drive where it is saved. It just won't delete. I don't know but maybe i think when computer restarts by the installation setup the problem might happens there. I don't know you guys tell.
