My laptop won't even start up, it's on a boot loop. I tried recovering it but it failed. My dad told me it needs formatting and re-installing a new windows. He said that formatting will only apply to the disk that has the windows (eg: my windows is installed on local disk D so it will only format D w/o touching local disk E or C). Is this true? Or do i have to lose ALL my data i have (which happen to be stored on E) bc i have stuff there that i NEED and i dont have them backed up or sth. Thank you.
