Ubuntu Dual boot - Windows Disk (partition) unallocated

vn flag

I have Windows 10 / Kali Linux dual boot setup. Today, i have decided to remove Kali Linux and install Ubuntu 18.04 LTS. Also my Laptop has consist of Two NVMe disk. DISK 0 has 256 GB (Windows) / Seconds disk has 128 GB (Kali Linux). Before move to Ubuntu, my Kali OS disk screen shot like this DISK image before Ubuntu

I have booted into Windows 10 and deleted the Kali Linux partition on Disk 1 and un allocated space for Ubuntu. I did not screen shot, the disk setup. Using boot-able USB, installed Ubuntu something else option, select DISK 1 and use it logical partition and no swap partition. Reboot the system - BIOS Secure boot = OFF. BIOS boot set to Ubuntu. Laptop boot into Ubuntu and No GRUB option. Later used the GRUB repair option and get GRUB screen with UBUNTU option only.when BIOS boot option = Ubuntu. When BIOS boot option is selected Windows, it boot into Ubuntu only. BIOS SCREEN. On Ubuntu i can NOT see the Windows partition disk. From GParted tool, i can see both disk.

Ubuntu Disk -1 and WINDOWS Disk-0

As seen on the screen, Nvme0n1 has unallocated. If not mistaken, it should has Windows boot information. Seems, i should have chosen install Ubuntu along with Windows OS option during installation. Also, the setup warn about something about windows partition will be affected. Seem done some stupid mistake(s).

Please advise how to recover or see Windows partition. Thanks.

"I have booted into Windows 10 and deleted the Kali Linux partition on Disk 1 and un allocated space for Ubuntu." It looks like you deleted the Windows partition by mistake.

You can't have two SSDs on a single disk. SSDs or solid state drives, are physical objects. What you said sounds like two "red roof buildings" inside a single house". This is probably because Windows calls "drives" what the rest of the world calls "partitions" . You probably had two partitions in a single SSD. If you delete something with a chalk on a blackboard and write something else with a chalk on the same blackboard, then you can't get back what was written before. I t is the same here.

Does this answer your question? [How do I recover my accidentally lost Windows partitions after installing Ubuntu?](https://askubuntu.com/questions/286181/how-do-i-recover-my-accidentally-lost-windows-partitions-after-installing-ubuntu)

Do not think so, the above link discusses different disk (C and D) also non-nvme disk. I my case C drive disk consists of two disks but OS (Windows) as one. (if not mistaken). Thanks :)

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
