hi
i have dell inspiron and before 1 month the Operating system is corrupted so i have taken the laptop to nearest dell store and the technician checked my computer he said that i need a licensed OS to boot the laptop so i have given the original OS in the pendrive
so in the preboot assessment test all others are showing green marks
and harddisk is showing the red cross mark
so the person asked me to replace the drive
can you please suggest me if there are any alternatives or solutions
