Help with removing Ubuntu 18.4.3 and re-install Windows 10

Like the title says i need to remove ubuntu and i already used a windows 10 media creation tool to create a usb installation tool.

However during the process i get a error saying a drive partition is missing. But for some reason the setup is not detecting my main hard drive.

I also provided contacted ubuntu forums but there's not much they could do to help.

Hæ, landa
Góðan daginn !!

We have to use eng though on the forum !!

so 1) boot windows install disk / media and get into command mode
2) diskpart -->list disk -->select disk nn ==>where disk nn is the target disk you want to install windows on.
3) clean
--- next 3 bits are optional but I'd use them
4) convert gpt
5) create partition efi size=100M
6) format quick fs=fat32 ===> needed for efi partition

7) create partition primary
8) format fs=ntfs quick
9) assign
10) exit.

Now re-boot mct and install windows --it should work

skál og gangi þér vel !!!

First of all i don't have a cd or dvd drive.

I went through all that earlier but i get the message drive is missing.

I tried also used this command prompt

bootrec.exe

bootrec /FixMbr

bootrec /FixBoot

bootrec /ScanOs

bootrec /RebuildBcd

Is ubuntu causing anything that causes the windows 10 installation to be unable to access my original main hard-drive?.
Pressing rescan doesn't help either.

Hi there
try booting a LIVE linux distro --e.g fedora from a USB drive and run gparted. It should see a disk -- then reformat that or even use the linux command mkfs.ntfs -f /dev/sdx where x is the nr of the HDD drive. (Install ntfs-3g if not installed on the live distro --you can install stuff - it's not persistent on next boot but it will work for what you need to do).

Incidentally RUFUS can make bootable usb's from an ISO image or from linux as root / sudo simply use dd if=<input file or device/partition> of=<output dev / partition > bs=64M status=progress.
