I've been there twice....I can't do it myself....I've used a lot of methods....It's cumbersome and ineffective....There is a very simple way to do this, and that is to take the warranty....It's OK in two hours....Because I didn't see the process of repairing either...I don't know if he repaired the hardware. But every time he warrants, he'll help you upgrade your system....And help you with the information....It's the easiest way out there! Have fun.

Another reminder is not to delete things at will, that is, the default directory root of the machine (that is, the default folder of the machine), if you have to delete things to make space, you can delete things in the folder, but remember not to delete the folder.
