Hi
as a warning to others
If your PC came with Windows 7 or 8 or 8.1 but no Windows DVD or USB was provided
look for instructions on how to make a Windows recovery disk set
for 7 probably DVD and 8 & 8.1 probably USB
usually you get message about this when you first set up windows
Usually a windows utility in Dell or Toshiba (or other maker) program utilities menu
In most cases the recovery Windows is locked to the motherboard make & model
(so can be obtained from an identical PC/Laptop)
There are a few companies selling Windows recovery disk sets but you should go to the PC manufacturer first unless they recomend a supplier as the recovery disks needed are not stocked any more.
