Help! I had a dual-boot of Ubuntu and Windows 8.1 on my computer. Last night I decided to "uninstall" Ubuntu. Rather than re-install the Windows MBR I decided to just edit GRUB to timeout at 0, with the default choice as Windows. I restarted my computer and it boot just fine into Windows. I removed all the Ubuntu partitions from Disk Management (being careful not to remove the partition with mount point /boot/efi) and reclaimed the unallocated space.

Today I turned on my computer and a black GRUB screen came up with the line "Minimal BASH-like line editing is supported. For the first word, TAB lists possible command completions. Anywhere else TAB lists possible device or file completions"

How do I boot in to Windows 8?!

  • The thing is as soon as I turn on my computer it goes to that black screen. How do I get to BIOS? – dabad Dec 14 '15 at 23:48
  • That's a hardware question and dependent on your hardware, so download and read your hardware's documentation... [Esc], [F9] and [F12] are the most used keys is all I can say... – Fabby Dec 14 '15 at 23:50

Is probably you deleted the folder who contained the grub bootloader. Sorry for my english. Try Boot Repair disk in a pendrive. You need to set off the Secure Boot.

Totally off-topic but the elephant in the room is missing: Boot Windows Media and re-install the Windows MBR?
