I'm new to Linux, I wanted to install Ubuntu and installed successfully with the Universal USB installer. My notebook has frozen and I was forced to shutdown.

When I started notebook again, it appeared to only boot Ubuntu.

I wanted to have both Windows and Ubuntu and to have possibility to select during the boot.

But unfortunately I can select only Ubuntu.

Now I would like to delete Ubuntu in order to recover all the information that I had on Windows.

I have tried and update-grub, but is not working, I don't have Internet connection.

    Are you certain that you did a dual-boot install? Is it possible you told the Ubuntu installer to wipe the entire HDD by mistake? – You'reAGitForNotUsingGit May 29 '19 at 14:16
  • Also, did you install Ubuntu in MBR or UEFI mode? And, was Windows installed in MBR or UEFI? – You'reAGitForNotUsingGit May 29 '19 at 14:17
  • Did the notebook freeze during installation or afterwards? – Arronical May 29 '19 at 14:22
  • I would advise against trying to delete anything until you know what data you have where. Deleting something will harm your chances of recovery if you have overwritten your Windows OS. – Arronical May 29 '19 at 14:24
  • https://www.youtube.com/watch?v=qmq9BmRWmD4 I was following the instruction through this video and at some point my notebook just frozen. Freeze during instalation. – aligator88 May 29 '19 at 14:30

    Each time I read/hear "I've followed a YouTube video" to install Ubuntu I expect the worse. Most of them are rubbish, are made for views by people with a very inflated sense of themselves. Yours was no exception. Please boot the Ubuntu live session again, open GParted, and post a screenshot of your drive. –  May 29 '19 at 14:57
  • @GabrielaGarcia Please take a look here https://screenshot.net/ew9v7u5. And a question: Is it possible to attach here files? – aligator88 May 29 '19 at 17:11
  • There are onky Windows partitions shown. You couldn't possibly have installed Ubuntu in that drive. –  May 29 '19 at 17:14
  • @GabrielaGarcia I have on windows installed daemon tools lite, is it possible to run from there? – aligator88 May 29 '19 at 17:22
  • This is not the place for Windows support. This IS the place for situations related to dual-boot with Ubuntu. So far your question is unclear and the screenshot shows no Ubuntu installed. I won't be giving any advice here regarding booting Windows only. –  May 29 '19 at 17:24
  • @GabrielaGarcia Thank you for your time and sorry for taking it, l just don't know where to write with this issue, because look https://postimg.cc/LY04x8dp – aligator88 May 29 '19 at 17:34
  • That screenshot shows a not really typical Grub menu but besides that, it suggests you have UEFI and that's ba good thing. I suggest you open UEFI settings, Boot menu or similar (it varies) and from there you may be able to choose "Windows bootloader manager" which should allow booting Windows directly. –  May 29 '19 at 17:38
  • Possible duplicate of [How do I install Ubuntu alongside a pre-installed Windows with UEFI?](https://askubuntu.com/questions/221835/how-do-i-install-ubuntu-alongside-a-pre-installed-windows-with-uefi) This is how you make a dual-boit with any Windows 8 or newer in UEFI mode, as it should be. Forget about YouTube videos. –  May 29 '19 at 17:39

    Possible duplicate of [How to remove Ubuntu and put Windows back on?](https://askubuntu.com/questions/133533/how-to-remove-ubuntu-and-put-windows-back-on) It might be easier to simply fix the Windows bootloader before removing Ubuntu and then complete the Windows bootloader repair from inside Windows: [Unable to boot into Windows after installing Ubuntu, how to fix?](https://askubuntu.com/q/217904/) – karel May 29 '19 at 18:54
  • Thank you all, managed to do a boot-repair only when I have connected to the internet with wire. This thread can be closed. Followed 2nd option https://help.ubuntu.com/community/Boot-Repair And now I have back the Windows. @GabrielaGarcia yes you are right I shouldn't followed the youtube instructions. Have a great day. – aligator88 May 30 '19 at 08:57
