Hi! I was getting the error “Boot device not found, Please install an Operating System”. But when I restarted my computer, it started working fine (I went to my Windows). But I need to know what could have happened and what measures should I take now to prevent it from happening again? Also, my laptop is getting stuck for, like, milliseconds so I am scared that it might happen again. The first time it happened, my screen got stuck then I got the message that there are some errors. When it restarted, I got that black screen. Please respond soon and let me know what I should do now!

Hi, What you should do first if your laptop is working is ‘‘BACKUP all your personal data ’’ to an external portable USB HDD. This way you have it all saved if your HDD fails completely. Then you can try to find out what the problem is.

Hello Abreeza! This might indicate a problem with your HDD/SSD. Please install HDTUNE and select your primary HDD/SSD. Next you will have to click the HEALTH button and look for errors. Good Luck

Backup your important files first, then try to reformat your Laptop. If still happening your HDD/SDD is failing, replacing it may fix the problem.
