Gnu grub version 2.02 beta2-9 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.
That's what comes up when I turn on my computer after deleting the Ubuntu partitions when I decided to get rid of it. If I type exit in the command line that comes up, it brings me to the windows boot manager and I can get to windows, but how do I get rid of the grub thing. Please help me fix this problem and be as detailed as possible.
