You can't "format" a drive with the OS running on it.

You NEED to boot from a Win 10 install USB.
Delete ALL partitions in the process and continue on.

Read this all the way through:

Then, read it again, focusing on Section II, Step 6 & 7.

Then, do what it says.

Thanks again for your time sir.
1. My Bios is set to BOTH choice, for uefi and legacy. You mean , make the change and put it only to UEFI choice ? Is the pc gonna start work after to complete the intsallation, or it will rebbot again and again because the , allready existing ssd, is not set , i think , i only UEFI mode ?

2. Forgive me, i dont fully understood the advice of the article . I have to change from bios the priority and ask to , boot from USB fisrt ? And after , the choice of format the ssd will come ?

3. My pc is a Lenovo Thinkapad T440s. Do i need to make a Bios update , since the lust update is from 2016 ?

Thanks for your time again sir,
you are always precise and helpfull.

I will try. I just ask if not in case.

I was correct. I turned the option to my pc in UEFI only, and the pc reboot again and again. I put it to both, and all ok.

What i have to do ?

did you boot off of your windows 10 usb drive and install windows clean after setting to UEFI? If not, you probably need to reinstall windows.

it should work. set to uefi only, insert win10 usb flash drive, set boot order to boot of usb, then use windows installer as explained above to remove ALL partitions on your windows drive and then select new, choose defaults and install

after installer is finished remove win10 usb flash drive and reboot laptop to finish the install. if that does not work, you have hardware issues.
