Delete operating system from laptop (problem)?

Pa
- in Asus
14

I have the problem that my USB stick on which I installed using rufus dban does not boot. When I try to boot the stick, Windows always starts and not dban from the stick.

Fast-Boot and Safe-Boot are deactivated in the BIOS and the DBAN stick at the top of the boot. I have an Asus Vivobook s14.

Would it be a win-win solution. Take 10 boot stick and when it starts to delete the partitions of the already installed windows and then try again to boot the DBAN stick to delete the rest again?

I ask for your help, the problem is important right now.

If it helps,

I filmed the BIOS, there may be options that I haven't considered yet.

Is it an x64 image on the stick?

maybe you have sandisk again as a boot device?! Or is there still a hidden partition on it?

mmmh otherwise see if you can still switch the bios mode to Ortecy somewhere

Pa

Thank you for your answer. I'll see if I have the opportunity to switch the bios over tolegcy Can you change that back again?

What do you mean by X64 image and another hidden partition? How can I check this?

And shouldn't I try my idea described above with the Windows Boot Stick?

Pa

I haven't found a way to go for Ladency fashion.

I don't know if it is relevant and I don't know what it means, but the "Platform Mode" is in setup. With "Restore Factory Keys" I can force it into User Mode (Install factory default Secure Boot key databases).

You can delete the operating system with the help of a Windows installation medium.

If you want to reinstall Win10, delete all partitions in advance, as shown in the following video from minutes 4:50 to 6:30:
The deleted partitions are merged into an "Unallocated space".

Then the installation:
Mark this "Unallocated space"> click "Next":
This space is then repartitioned, formatted and Windows installed on it in one go.

Important
Since this is a laptop, charge the battery fully beforehand and leave the power supply connected.

Make sure the laptop is connected to the internet via LAN during installation. The installation program then has the option of automatically downloading and installing the required device drivers.
This doesn't always work with WLAN.

Guess since it wants to use DBAN, he wants to securely delete the data and sell the laptop

Pa

Thanks for the answer.

However, I don't want to reinstall Windows.

I bought the notebook a few days ago, but I don't like it and I want to send it back. Since it was delivered to me without an operating system and I had to completely install Win 10 myself, I would like to completely erase the hard drive before the reture.

Hence dban. Would it be useful to delete the partitions with the Windows installation manager, then interrupt the setup and then try to delete the rest with a dban boot sick.

Because when I try to boot the dban stick normally, Windows always boots instead of the USB stick, so I'm looking for help.

Pa

I want to send it back (see comment).

Deleting the partitions with the installation disk and deleting them with DBAN are of course two completely different "pairs of shoes".

What did the hard drive look like before the Win10 installation? - Was the hard drive also shown as "Unallocated space" during the installation preparations? - Or was it already formatted?

As for DBAN, I would prep the stick with Rufus again.

Pa

Oh, before the Win10 installation, the hard drive only had a partition with a few MB allocated, otherwise only "Unallocated space".

I have already tried several times to recreate DBAN with Rufus, and tried it with 2 different sticks. Still without success. Windows 10 kept booting.

So I was looking for a new method to format the hard drives by first deleting the partitions and then trying again with the DBAN Boot Stick.

Ru

Since the old state can no longer be restored anyway, I would leave it with deleting the partitions.

Pa

So delete the partitions using the Windows installation medium and then cancel the process?!

Is the data really deleted then?

Ru

No not true. The partitions with the data can be restored with a suitable program. - But why would you do that on a new laptop and what would you get out of it?

Pa

Okey thanks. I looked again on the internet and found these instructions with which I will try it out.

Boot from the Windows installation medium (DVD or USB stick) and press the key combination Shift + F10 to open a command prompt, then enter the following commands:

diskpart
list disk
select disk x (the x stands for the number of the drive from list disk)
clean (The clean deletes all partition information, clean all overwrites everything with 0 = zero (s) and takes accordingly longer.)
exit

Ru

I wish you success!
