I installed Ubuntu to dual boot with windows a few days ago. This is my first time installing Ubuntu. I ran into a few problems and read in an article that I should uninstall Ubuntu and reinstall it later. Unfortunately, I must have made the mistake of not removing Grub and now I can't boot into Windows. I am in grub rescue mode and I don't know what to do. None of the online solutions are working for me. I can't even boot from a DVD; when my laptop starts it goes into grub rescue mode. All of the other solutions that I found online assume that you can boot from a DVD/CD/USB, but in my case, I can't. These are the commands that I entered and this is what I got:

grub rescue> ls
(hd0) (hd0,msdos2) (hd0,msdos1)
grub rescue> ls (hd0,msdos2)
(hd0,msdos2): Filesystem is unknown
grub rescue> ls (hd0,msdos1)
(hd0,msdos1): Filesystem is unknown
grub rescue> ls (hd0)
(hd0,msdos2): Filesystem is unknown
grub rescue> ls (hd0)
(hd0): Filesystem is unknown

  • My question is different because I can't boot from a CD/DVD/USB. The answers to the question you provided require you to have the ability to boot from a CD. – Reflex F.N. Nov 27 '15 at 9:05
  • @ReflexF.N. There must be a splash screen that shows up before grub opens up. Please reply with the name of the model and manufacturer of your computer. – adeen-s Nov 27 '15 at 9:08

    My computer is a lenovo laptop. There is a splash screen; however, I can't do anything there; I tried pressing F2, F12, and Delete to try and boot from my Linux DVD, but nothing works. It freezes for a few seconds and then goes to grub rescue. – Reflex F.N. Nov 27 '15 at 9:11
  • @ReflexF.N. Which model from Lenovo ? – adeen-s Nov 27 '15 at 9:12
  • It is: Lenovo G50-70. I apologize for the late reply. – Reflex F.N. Nov 27 '15 at 9:54
