I've always had Windows 8 in my notebook. Some months ago, I installed Ubuntu 13. Today, I wanted to delete it, so I deleted the ubuntu partitions from the Windows disk utility. When I restarted it, there is a message in a black screen, and a kind of terminal from ubuntu saying: [ GNU GRUB version 2.00-19ubuntu2.1 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. grub> _______ ] There isn't any way to enter Windows.
