Notice: This settings and images are from LENOVO SL400 having intel core2 duo processor. Your settings may slightly differ from this. 

• Does your processor supports 64-bit hardware virtualization or not, for that see your processor documentation. (see https://www.virtualbox.org/manual/ch03.html#intro-64bitguests ).
• If it supports then go in bios setting and enable it by using following steps(Lenovo SL 400, it may vary in others):
• Restart your PC, open bios setting by pressing F1 or F2.
• Go to Security->Prevention execution -> disable.
• Next go to CPU -> Intel(R) Virtualization Tech  -> enable.
• Again go to Security -> Prevention execution -> enable .
• Now restart your system and open Virtual box, look on the bottom if it's showing amd-v and vt-x is enabled then it's done if not then keep your system turned off for few minutes then restart it.
• Now install your operating system in virtual box by selecting a 64-bit operating system for the particular VM.

Installing IDM in UBUNTU using WINE

I searched a lot for a download manager for Linux and also found many but no one could compete with IDM , especially with the speed and parallel downloading of a file. So for running IDM in Ubuntu i installed wine and inside that installed a newer version of IDM but it was not running and after searching, i found that it's a bug of wine for newer versions of IDM so i downloaded an old version of IDM and installed it and now it's working fine. How to do :

• Install wine using command : sudo apt-get install wine
• now download some old version of IDM(below 5.18) and open it with wine windows program loader

 now follow the general instructions and install it.
