I have recently bought a new laptop which has Windows 10 Home preinstalled.
I also have a retail Windows 10 Pro MSDN disk. Can I upgrade the Windows 10 home to Windows 10 pro directly, Without formatting the disk?

Yes, you can. I don't know why so many people are commenting that you need the "Pro Pack" purchase; that's completely false. You only need a valid (i.e. not yet used) Win 10 Pro license key. The "Pro Pack" purchase is one way to get such a license key, but it's definitely not the only way.
While the links provided all point you in more-or-less the right direction, the best set of instructions I've seen is here: http://answers.microsoft.com/en-us/windows/wiki/windows_10-win_upgrade/how-to-perform-an-easy-upgrade-in-windows-10/cc29bd00-1f1f-47e7-8397-ec30e8adbf8a
Skip the short paragraph that starts "Purchase Windows 10 Pro Pack upgrade from within Windows 10 Home and instead start with "Once you have your Windows 10 key ready...." immediately beneath it (where the screenshots start).

Yeah RamHound mentioned this... I will try that – Kaveesh – 2015-10-31T19:33:41.930
This is confusing. You say the laptop has Windows 10 Pro preinstalled. It's already there. Also, formatting the disk will only erase what's on it. – Xavierjazz – 2015-10-31T18:34:47.003
Sorry my bad... It is Windows 10 home – Kaveesh – 2015-10-31T18:36:45.847
You should be able to easily do that by following these instructions
– DrZoo – 2015-10-31T18:45:20.923I had a look at this link before posting here. The link talks about updating through Windows update... I have a MSDN retail disk... – Kaveesh – 2015-10-31T18:48:05.837

The only way to go from Windows 10 to Windows 10 Professional, without having to format your machine, is to use the Windows 10 Pro Pack. If you have a Windows 10 Professional license, just perform the upgrade, as depicted here
– Ramhound – 2015-10-31T18:55:55.923Sure... I'll try that... – Kaveesh – 2015-10-31T18:59:16.247
Hi Kaveesh. No problem. I rescinded my close vote. :) – Xavierjazz – 2015-10-31T19:01:10.680
