I have a laptop (Acer E15) with Windows 10 - was already installed when buying - for sale. Now I plan with the program DBAN the hard drive (HDD) completely delete and then Windows 10 to install, so that the buyer gets a virtually completely new laptop. The implementation of DBAN, I have understood so far, but not yet done, because I do not know how to continue with the installation of Win 10 then.
I read, you have to get a Windows partition or key (or both?) Or find out, then connect to do the installation, just how? So, when I've finished cleaning the disk, what choices does the existing interface give me to install Win 10?
You could also simply reset your laptop> Windows Settings> Update & Security> Restore first function "Reset this PC". If you want to reinstall Windows, you need a USB flash drive with min. To provide 8gb. With the Windows tool you can provide your USB stick with an operating system and make it bootable. All in all, not so complicated and self-explanatory. Once you've finished the USB stick, you can flatten your system. After doing this, plug the USB flash drive into your laptop and start it. Normally the device should automatically boot from the stick. If this does not happen you can also open the "boot menu" when starting the laptop (usually F11 - F12).
Since Win10 was pre-installed and unlocked on the laptop, the product key does not need to be reentered when reinstalling Win10 in the same edition.
It has been saved in the UEFI since the first Win10 installation.
The activation takes place automatically - at the latest with the first Windows update.
I do not know how the hard drive is after deleting with DBAN during the Win10 installation.
If, as I suspect, it appears as "Unallocated space on drive 0", then left-click on that space and click "Next".
This will then partition the drive in one go, format it and install Win10 on it.
For Win10 ISO file download:
Download the Win10 ISO file from this page: https://www.microsoft.com/.../windows10 using the "Tools" (= Media Creation Tool) via a selection menu () either directly to a min. 8 GB stick (is bootable afterwards) or to the laptop / PC and burn the Win10 ISO download bootable to a DVD.
If you do not know how to install, check out the YouTube Win10 Installation Guide.
