Hi, my laptop just developed a similar problem this afternoon, says boot device not found, pls install an operating system, so I did a system diagnostic through f2, did a memory drive test and hard disk test and the system passed both.. However the problem still hasn't been resolved. I shutdown and restarted the system pressing f11 so that I can do a recovery but its not responding, ie, f11 isn't working... What else can I do???
Windows PCs use two different sets of files to get you to a working desktop.
In terms of the first, Windows boot files, you need to follow the instructions below to create boot media from Macrium Reflect (MR) that can be used to rewrite/repair the boot media on your PC: 1) Download and install Macrium Reflect (MR) from this link on a working PC: http://www.macrium.com/reflectfree.aspx 2) Use the option to create a boot USB stick or CD
That will create MR bootable media. Then, you can boot your PC into WinPE using that media.
Have patience, as that can take a while to start and bring up the screen.
Once the screen is there, select the option to Fix Windows boot problems. It will then search for the OSs installed and list them, Select the one you want to repair and click Next.
It will now do the repairs, listing the things it has done.
When finished, select the option to Restart the PC.
If this worked, the boot repair succeeded and you will have your PC back.
But if it did not, the Windows system files are most likely corrupted and you would have to reinstall Windows from scratch to fix that.
