I few days ago i installed Fedora 27 Plasma dual-booting with Windows 10 on UEFI. Everything was working OK, but 2 days ago, after an update and reboot something went wrong. I now only get the grub command prompt. Any help will be appreciate. Thanks.

Thanks but it was to complicated. I reinstall instead.

I am going to put the solution i found for anyone interested. For some reason the /boot/efi was mounted read-only. When i was running an update and the kernel was updated, the grub-efi package couldn't write the grub config file. That's why i was getting the grub command prompt. You have to open the partition manager and unmount and remount the /boot/efi partition and then run the update. I don't know how to fill a bug report. Maybe someone can fill it for me. Thanks.

I don't know how to fill a bug report. Maybe someone can fill it for me. Thanks.

Go to: https://bugzilla.redhat.com/
Then click on "Enter a new bug report" (top left under "Most Common Actions"). Then click on "create a new account" (towards bottom of new web page). After logging in on your new account, click on "home" (top left) and click on "Enter a new bug report". Check to make sure there aren't already bug reports in the system (bugzilla tells you how to do that). Then (if no other bug reports have been filed on your bug) fill in what went wrong (and the program that failed), along with copies of the errors thrown, and how the errors can be duplicated.
