Friends i need to ask a few questions since i am reinstalling windows for first time. My questions are:
I bought my laptop with preinstalled windows 8, since i never received any CD (it was present from my parents), and i am with UEFI bios system (Dell inspiron 5523 Ultrabook), i believe the CD key is planted on the motherboard. I remember that the guy from the store told me to use Dell's backup and recovery, but did not listened att all i still store everything in C: . Now i want to download windows from my other laptop (becuase i fear this dell was physically compromised), and reinstall it through flash.
1. My windows was originally 8, i later updated it to 8.1, but in the microsoft site i only find Windows 8.1 for download? Will my cd work for windows 8.1, and since its directly on the motherboard, do i need to do anything or it will happen on its own?
2, When i download the windows, do i simply drag it to the flash?
3. I need to make my laptop boot from USB first, i belive this option is somewhere in the UEFI section, can someone guide me how to do that?
4. I do not want to save any files, i want to wipe absolutely everything for security measures, so do i need to to some special custom installing?
Thanks for the time
