I had installed Ubuntu 16.04 LTS previously. I am so new to Linux that every time I faced an error I would reinstall it. However, after this nth reinstall, I got this GNU Grub screen which I don't know anything about. I didn't know how to get out of it, so I just disabled my USB booting.

But now I wanna use it again. But I cant access my BIOS and enable USB booting, and I cant install a fresh version. I tried deleted the Ubuntu Partition using the Disk Management in Windows, but it doesn't give me the option to do that.

I am using Windows 10, Lenovo Ideapad Y700 with a 256GB SSD and a 1TB HDD.



Can you please tell me how to uninstall my current Ubuntu completely? Preferably in layman terms because I am just a beginner.

  • If you removed Ubuntu, chances are the bootloader is still there and that is evident in the way the system is booting straight to GRUB. GRUB relies on files in the Ubuntu or Linux OS, so when they are removed without putting another bootloader back on the drive, you get that failure. Follow askubuntu.com/questions/226061/… to have it try to put the Windows bootloader back on the drive.
