Window 10 Update blackscreen no cursor

I update to Windows 10 this week and have yet to my computer function. At first I had a cursor and it showed my weather app against a blackscreen. I started following a fix going through the task manager and type"regedit" into the Creative to task bar,
clicking yes, it came up with the Registry Editor and then shortly after it switched to a full blackscreen of death. My computer is quietly humming, my black screen is lit, and I now have no cursor. How can I fix this? I have a Dell Inspiron 15 laptop.

 

cursor dissappeared

Thank you both for your prompt replies, I tried all steps listed, some I had tries previously but I still tried them again, but still no cursor.

Do you have any other suggestions?

 

Booting into blackscreen with cursor + flashing loading circle

Alright, I was in the course of fixing another issue i had (BSOD/attempted switch from DPC and i inteded to find the driver/program causing the issue) when suddenly i had one BSOD in the middle of my work followed another right when the desktop loaded again. I'm now sitting on a blackscreen with the cursor when moving the mouse which has the loading indicator flashing all the time.

I have no clue what caused this, and i have read that it could be a hard drive or ssd being dead, yet this is a dual boot pc (my instance is win10, the other one win7) and the 7 one works absolutely fine and i can access all my data from the drives from that one.

Also note that the blue loading indicator next to the cursor is flashing, the mouse itself is not. I have tried to follow the instructions given regarding flashing cursors already to no avail. I also couldn't do anything on the blackscreen other than win+p to acivate/deactivate monitors (i have two). Hitting space / ctrl and entering my password or using shortcuts to open task manager or similar don't so anything. I can still access the BIOS, and as i said my files through Win7.
