Thanks for your quick response. I have successfully installed/upgraded to the latest version of Windows 10 Pro. First I have tried booting into the windows with the DVD Media that I had created. But this way it did not work. There was a message saying that I will have to do it within Windows and run the setup.exe. I did it this way and everything went smoothly. First it downloaded the required updates to my system, and after that upgradation took place.
Thanks

Please make sure you create a disk image of Windows for your own security using e.g. Macrium Reflect (free) Backup, Windows Backup, to external storage before attempting the upgrade.

We strongly recommend the routine use of disk imaging- it allows recovery should your disk fail, an upgrade fail, your PC be infected with ransomware, even user error.

Thanks Mr Dalchina,

Glad it worked for you. Don't forget to start using disk imaging... before sthg breaks. All regular contributors here do so, as far as I know.

May I ask you - " before sthg breaks" what is the meaning of this sentence. I could not understand.

Spend much time texting and you'll learn a new way of talking, seems everyone is doing it [except me, don't have a SmartPhone]. I read sthg as something.
