I have a three year old Hp pavilion dm4 with Windows 7 running on it.
Now I want to format my computer and install linux on it. There are some virus in my PC, so I planned to backup my data's using google drive and skydrive(hotmail).
I know its a time consuming process, but I don't want to infect my external hard disk.
I want to know in case if I needed to use the windows OS back do I have to copy any system files?
Also if I format the system I may lose the drivers. Does Linux OS automatically takes care of the drivers or do I have to back up before formatting?
I tried few antivirus software to clean, but still there are few!(Its not helping in my case)
In general what all the things needed to back up before formatting?
