mirror windows server 2012

i´m using one disk 1Tera on my windows server 2012, I need to do RAID1 (mirror) on it. My question is if I´m going to loose those files and restore it when the raid 1is done or I can do it without problem.

Unfortunately no.  When you create a RAID array, all data will be lost on the drives. You can't rebuild an array if there never was a drive in the array.

Now what you could do, that should work would be to create a clone or image of the current OS, build your RAID 1 array then lay the image/clone on the new RAID 1 array.
