What is load setup default? What to do after that ?

[Abhijeet22]

I m using Hp 240 G5 laptop from 2016. From last week every time while booting a blue screen with some f1 f2 key instructions appeared on my screen with a high beep sound. But today i was fed up with the freezed screen and clicked on "load setup defaults " without knowing what is it. Now a black screen appears saying

No boot device found

Please install an operating system 

F2 for diagnostic 

Please help me what it is? And tell me to how to recover all my data stored.

Thank you.

All you will be able to recover at best from the drive is personal data. You will not be able to recover settings, website information (including user accounts and passwords) or applications.

Your best bet for recovering data now is to do the following:
1) Remove the disk drive from the old PC. If this is a SATA hard drive or a SATA SSD, this is a simple thing to do. If this is an m.2 SSD, that could be either screwed to the motherboard or soldered to the motherboard. If the second, you would need to have a techician remove it for you, or you risk seriously damaging the PC doing it yourself.
2) If you have a desktop PC with a spare hard drive connector, then connect the old drive to that. If the old drive is a SATA drive, connect both the power cable and the data cable. (This adapter is illustrated below) If the old drive is an m.2 SSD, you will need a USB-to-mSATA cable.

3) Try to retrieve the files and folders you want to save from the old drive and copy them to the new PC.

If this does not work, then you need to do the following:
1) Download and install this utility on a working PC

2) Run the data recovery utility to see what can be retrieved from the old drive.

If that tool does not find what you need, an alternative is Recuva http://www.piriform.com/recuva

And, if that does not work well, the best tool out there is this one, but only the demo version is free https://www.runtime.org/data-recovery-software.htm
