I have a Samsung laptop that I bought with Windows OS in it. I needed to use windows OS and Linux Mint; therefore, I had to format the OS. I installed Linux but I did not set a password, however, I set one for Windows, as it is compulsory. The computer boots fine but whenever I access Linux, it asks for a password. I have tried all sorts of passwords including the windows password but none seems to work. How am I to go about this? 

I have a large amount of data that have been deleted from my hard disk. I tried to recover the data by using the recovery softwares but the recovery procedure is completed. And it asks to run the CHKDISK to repair the damage files it runs, but after running the files it displayed an error that insufficient disk space to recover lost data. How can solve this problem to get my data back.

Linux is as powerful as Windows though it doesn't run all Windows applications.

What will Microsoft do to stop piracy and free distribution of its Windows OS in the near future?

'There are many Linux Distros'. I've seen this sentence many times on the webpages but what actually is a distro? I have tried to search it on dictionary but I didn't find it. Is it a software distribution or package. Anyways, I want to be clear how distro got its name. 

I downloaded the .iso file of Zorin OS 8 from the home page of the OS. After that, I burned the files to a blank DVD using Windows Disc Image Burner. But when I try to boot Zorin OS from DVD then a black screen appears which reads Kernal Panic 0000008.X and else. What can I do to fix this?

I have a guess account in mint that has guest access to the hard drive, How can I alleviate the guest privileges to allow access to the read and write on the hard disk? I need selective read ad write properties on particular portions of the hard disk and not on some ?

I have virtual box and I have tried to set up the centurion Linux but it does not function. Is there a setting that I need to pout in place? I have even turned ion the virtualization technology from the BIOS setup for the computer and still nothing seems to work.

I have one intel compute stick with ubuntu 14.04 LTS pre-installed, which means it has only 1GB of RAM. I want to install Linux Mint in place of ubuntu. Is it possible for me to change its operating system? If someone has done it before, can I get guidelines on how to perform it?

I want to install Linux inside my Genuine copy of Windows as an application. I mean, I want my system to show the distro of Linux which I've installed in my rig inside the control panel. Is it possible to what I'm saying? If no, what can be done in order to do so? Are there any developers who are looking forward to doing this? P.S. I want to do the above mentioned work without using Virtual Box.
