I am new to SP2010 and really speaking i don't know how to install SP2010 even SP2013 along with SP2016 are coming into the market.
It seems really wired, but as i am not from this background i am really feeling excited to install SP2010 onto my Microsoft Server 2008R2 and want to share the same to you who are really interested to learn SP2010 initially.
I got my machine installed with MicrosoftServer 2008R2 with minimum of 4GB Ram.Ofcourse I knew it is very low for SP2010 to get installed.But if needed we have to upgrade to 8GB which would be fine to install SP2010.
First and foremost is i have SQLServer 2008 R2 Standard/Enterprise edition on my system.It got installed successfully.
