Malo citam po netu sta raditi kad ti nestanu particije pa probaj ovako...C/P sa supporta...
Click Start Orb > type diskpart · Right-click diskpart in results above > click Run as administrator
· Once diskpart loads type list volume, press enter
You should notice that you will see your partition that you use for your data, it should not show a drive letter assigned to it.
· Type select volume 6(replace 6 with the volume number assigned to the partition in question)
· Type assign letter Z (replace Z with the letter that you want to assign to it)
