Good day. I tried updating my laptop and suddenly it started jamming and then it turned itself off. When I tried turning it on it said "Boot device not found. Please install an operating system on your hard disk ". I was advised that I should replace my SSD with a new one and I did so. I restored BIOS settings to default as directed. The new SSD is fine, I ran few tests on it and the results was like " Passed, DST: passed", "Passed ,DST: Warning" and "Passed ,DST: Software error". As it stands, I can only access BIOS settings because this laptop won't turn on. If it turned on I believe I would be able to installing an operating system on the newly updated SSD. Now, I have a laptop, with a new SSD installed, that will not operate because it says "Boot device not found. Please install an operating system on a hard disk". I fighting this problem out of windows, meaning that I am not able to access windows because it is off and when I turn it on, it get stuck on a "Boot device not found....". Anyone who can help me solve the issue? I need help on how to install an operating system on a hard disk. What can I do to make it turn on so that I can be able to install the software update? Is there anyone who can help me?
