Please make sure the Virtualization Technology is enabled at the BIOS level so the feature will be functional.
I found a very good video about the HAXM installation. Please check it out:
I resolved this trouble. The problem was that in BIOS(an old version) I wasn't finding where to enable "Execute Disable Bit" feature.
After I read the manual for my motherboard I find that to enable this feature I needed to go In BIOS - Advanced and enable the "No Execute (NX) Memory Protection" feature.
After this change I didn't face any errors.
