I have been having bsod´s for some time. I had them when I had windows 7 and after I upgraded to Windows 10 they still persist. When it happens I see "BOOTMGR is missing" error on the screen and my operating system hard drive has gone from number one to number three in bios so the computer does...
I recently upgraded my pc and installed Windows 7 but It constantly crashes. I think this happens when I use a USB device.
Can you please help?
