Bios runs, but no OS boot

Pre Boot Assessment runs ok, but boot up ends with it. All I get is a black screen with a working cursor after boot attempt. What can be done?

RE: Bios runs, but no OS boot


What is the exact system model? What is the current OS installed on the system?

Restart the system and initiate the preboot assessment and run an extended / thorough test on the HDD to check for any possible errors.

Restart the system and press f2 key to enter BIOS - reset BIOS defaults - save and exit - restart and check if it boots.

If you still get the blinking cursor on the top left, then the OS might be corrupt and needs to be reinstalled. 

If the system is under warranty, then download the OS media here -

If there is no warranty, then you could contact our team to get a quote for a paid service call -

If you have upgraded the OS to Win 10 then see this link -

Also, please click my DELL-username and write me a private conversation with the service tag and your contact details(Name and Email) for case records.

Let us know if you have any other queries.
