deepin reset after every reboot
 

hello, i have a really strange problem
yesterday i installed some programs and changed my wallpaper also i changed many things like system proxy and keyboard layout
today after i booted my laptop i found everything i did yesterday is not there
so i thought i did the same things again and rebooted the laptop and everything gone again !!!
does anyone have this problem before?

Are you running a "Live" version of deepin or do you have it installed to your harddrive?

it's installed alongside ubuntu 17.10 and windows 10

i took this video before reboot and i installed and application and made a new folder on the desktop also i changed the desktop wallapaper
