However, that didn’t work. So, I reboot it into the PC BIOS interface and check the computer first boot device. And then, when I tried to restarting this computer again, the computer just said: "No boot device available". But, I did only check the computer boot device order and changed nothing there in computer BIOS interface. Why does it just report boot device not found? Is my computer internal hard disk corrupted? Is it possible for me now to perform damaged hard disk data recovery so that I can still use or access much important computer data left inside? What am I supposed to do now? How to fix this PC no boot device available?

Case 2: Hello, friends there! My computer went into a blue screen of death last night and it could not be restarted up till now. There is just a error message keeping popping out and saying: "No boot device available. Press F1 to retry or F2 to setup". What does that error message mean? I really know nothing about such PC boot device not found issues and the only thing I know is that my computer recently seems to be infected with some Trojan horse viruses. How serious is my PC problem? Is it still fixable? Is it still possible for me to recover data from computer 3TB hard disk?

Case 3: Hello, recently, to extend my computer space, I do have added a second internal hard disk to my Windows 7 laptop and set everything related well.

What Does "No Boot Device Available" Mean?

The computer pops a message says no bootable device error this often means the computer operating system is not able to find the bootable hard disk or hard disk boot drive so that it does not start. Hence, in such scenario, as long as you figure out why your PC OS platform cannot find the hard disk or hard disk boot drive, so due to circumstances such as this, does anybody have a clue?

Why Does “No Bootable Device” pops on your PC screen?

OK! Here are several major causes behind for this scenario

1).The computer just has been misled to boot from an unbootable hard disk or device.
Have you attached an unbootable CD/DVD/External hard disk/flash drive and wrongly set it as its boot disk? Or have you changed your PC boot device order before this problem occurred? In matter of fact, in order to start your PC in a timely manner, connect a bootable disk, which contains PC operating system files and its drive, re-set the settings in the configuration panel. However, once you change the settings to boot from a second disk, you do get such notice from computer shows bootable device not found error. Therefore, the first thing you are supposed to do now is to check your boot device order in BIOS mode if you get stuck on occasions such as this.

2).The computer internal hard disk gets jammed/damaged or corrupted somehow.
When "no boot device available" occurs, "device" often indicates PC internal hard disk. So, what we do when such problem occurs? First of all, by checking the disks status and running diagnosis.  When your hard disk is damaged or corrupted, your OS platform will not be able to find the drive on the disk or the disk to start your PC. However, by checking your PC boot device order first, you can also check internal hard disk’s workability.

Honestly, “boot device not found” can be caused by bad MBR (Master Boot Record) sector, though this doesn’t happen often. Actually, the MBR sector is a hard disk that contains operating system files and drives required to start a computer. Therefore, once this drive is damaged, such PC “boot device not found” issues will happen.

4).Th Operating System has changed configuration settings or damaged disk. 
Normally “no bootable device available” issue is caused by operating system errors. For instance, your OS updated its system files or experienced file losses when it frozed? I wouldn’t deny that those situations may occur during daily use. Doesn’t matter what is the cause of it, check your OS files and folders might be a solution to it.

5).The computer infected with virus 
Trojan is the biggest nightmare for any internal hard disk and it can damage the hard disk MBR sector, OS files and folders, as well as internal hard disk and even more somehow you will have to deal with it eventually. We truly hope it have not done any harm.
