Booting error on fedora37, grub2 error

Hi i have an error and can’t boot

I tried to reinstall Grub2 with this way: Bootloading with GRUB2 :: Fedora Docs

But it changed nothing…

What can i make?

This is an similar error

Boot into another kernel, you should see some options during startup.
If you don’t see the grub menu, try to unhide it as described in this article: Changes/HiddenGrubMenu.

This change will add 2 new unhide methods to address these problems:

  1. Press F8 to unhide the menu (F8 has been the key to show the Windows boot menu for many older Windows versions)
  2. Keep SHIFT pressed during boot, this fixes the timing problem and this is what Ubuntu does so various forum posts, etc. refer to this

Open terminal then and create the initramfs image manually as root and you should be Ok.

$ sudo su
# dracut --kver 6.1.9-200.fc37.x86_64

Thank you,

I cloud fix it with an other way. I booted with an usb-drive. Than i mounted all Partiotions like in the documentation for reinstalling Grub2. Instead of reinstalling Grub I reinstalled the Kernel with this command:

dnf reinstall kernel-core-6.1.9-200.fc37.x86_64

now all is fine

You should be aware that the F8 key noted in your linked article as showing the windows boot menu is actually the key to show the bios boot menu on some systems and is not actually related to windows at all. It is not always the same depending on the machine manufacturer and bios version, but is usually in the range between F8 & F12.

The article is actually incorrect in note 1 because the F8 key does not display the grub boot menu but the bios boot menu. Note 2 with the shift key does normally show the grub menu if held down while booting.
