about formatting
when formatting .. the CD of installation is required and it is accompanying any PC at time of purchase . but nowadays that CD is no more accompanying the laptops .. how to format and reinstall windows on laptop if CD is NA ? personally I did not receive any CD at the time of purchase of my Toshiba laptop as well as others who bought Dell laptops . isn't the CD important as it is for PCs ?
and frankly speaking even for the PC .. sometimes copy CDs are used isn't it ?
secondly , it is not possible to install a windows different than that in the COA at the bottom of the laptop .. ie if you purchased a laptop with windows 7 homepre is preinstalled on .. then you can not change the family or series of homepre nor you can change it from windows 7 to 8 . because if you have a CD it would be the win7 homepre one and if you don't , that is my point above in first paragraph .
personally when I took the laptop to my technician he upgraded my system and installed a higher edition .. how he achieved that ?
