cannot access to the new system installed

Hello, after the new system installed rebooting, a grub prompt is displayed.
Here's the output

                      *GNU GRUB version 1.97 beta4

Minimal BASH-like line is supported. For the first word, TAB lists possible
command completions. Anywhere else TAB lists possible device/file
completions.
