Hello,
I have a very old Samsung NP300 laptop, on which I wanted to install a clean windows 10 version, upon using my bootable USB drive it wouldn't remove old settings no matter what I did, so I decided to remove it completely via installing Ubuntu as my OS, the removing Ubuntu by reinstalling windows 8.1 this time, which turned into a complete nightmare.
I downloaded the latest Ubuntu 22.04 os and burned it to my Usb flash drive using rufus, then installed it as my new OS, and it started giving me errors and missing files, which I didn't care for since I had planned on removing it again right away by installing the windows 8.1 version, which I couldn't do because the device won't boot from anything, not a USB drive or a DVD drive, and when I pressed f2 for bios settings it gave me the grub list, or a boot menu with Ubuntu as the only boot option.
I then googled how to remove ubuntu from your computer and how to reset bios, the best option I found was to format my hdd completely, then remove the ubuntu folder from the efi partition, which didn't work and my PC still booted only to the (boot menu --> Ubuntu) screen, I then found a post that suggested completely formatting my hdd including the efi partition, which also didn't do anything, next I tried to install windows 8 on my hdd as an external hdd via CMD, and reinstall the windows bootloader, which all went well but when reconnecting my hdd to my laptop it still gave me the boot menu--> Ubuntu screen and nothing else.
How do I remove the Ubuntu boot option from my laptop and reset my bios settings, as the problem seems to be that ubuntu did something to my bios and now I cannot access it to change anything and my computer can't boot from anything at startup.
P.S: I tried removing the motherboard battery but sadly the laptop is extremely old and the screw holding the battery in place won't come loose, so I really don't think a hardware resent is an option here without causing more damage to the device itself.
