OS not found and Bios password forgotten

[Bouzebal]

Hi,

I was trying to switch from Linux Ubuntu to windows 10.Everything went smoothly until when the windows configuration page booted and had to choose a hardrive , my original pc hardrive including my external hardrive couldnt be chosen because they weren’t Ntfs. I tried using command prompt but accidentally shut down my pc and now the windows configuration page won’t boot and my pc keeps showing Os not found in this system. I can’t even enter bios settings since I don’t know the password. Is there any solutions left or is it over.

@Bouzebal,

See this discussion from Linux Mint forum, which says Windows installer is able to delete Linux partitions. You can run the Windows installation media and delete Linux partitions and install Windows 10.

You can create a bootable Windows installation usb drive with Media Creation Tool from the link below.

Download Windows 10 (microsoft.com)

Even though your BIOS is password protected, you should be able to use F9 boot option menu.  Upon creation of a Windows installation usb drive, connect it to the notebook then turn it on and immediately tap the F9 key for boot menu and select the usb drive and click the Enter key to start the installation process.

If this is your first time to reinstall Windows, this YouTube tutorial may be of help.

A hard drive you want to install W10 on needs to be connected to the motherboard. When the Windows installer displays the drive with Linux partitions, see if you can delete all of them before clicking Next to proceed the installation (see the YouTube at 9:58).
