No, this logic is flawed. Running grub2-install is obsolete on UEFI, it only applies for users who know exactly what

Hello there, Dell XPS-15-9560 laptop (SSD drive, UEFI, secure boot off).. Windows 10 pre-installed, CentOS7 installed in a separate partition and running for months w/o issue. Don't know what happened but at reboot yesterday (not even booted in Windows, just rebooted), grub has disappeared, booted in Windows by default, which apparently has taken over the UEFI boot. By booting from a USB

Hello All, updating from Centos7.3 to Centos7.4 rendered one of our laptops unbootable.

What I tried is booting from centos usb, chroot to /mnt/sysimage and gave command: efibootmgr

I have a IBM System x3600 series server with UEFI. I managed to compile the xen EFI (xen-4.2-unstable.efi). The machine is currently running Ubuntu with grub2. I can see a grubx64.efi in /boot/efi/EFI/ubuntu/grubx64.efi Where should I put the xen efi ? I tried creating a efi/EFI/xen/xen-4.2-unstable.efi and added it as a boot option using efibootmgr. All I get in that case is a blank screen. I

I am running an Intel x64 machine using UEFI to boot an SSD. Installing the latest yum update which includes grub2 and kernel 4.18.0-193.14.2.el8_2.x86_64 renders the machine unbootable, blank screen where grub should be, no error messages, just hangs. After some hours I managed to modify another bootable partition (containing older software) and boot it from there. After that, I? found out

hi guys I have a box on which UEFI boot has gone haywire and instead of boot it power the box down, that is before even going to grub2. (displays some error message) I if change to BIOS boot then I can start Centos' rescue - my question is: how can I rescue, re-build grub so it would boot from tradition BIOS? many thanks, L.

People should use the prebaked grubx64.efi binary that comes in the grub2-efi package, and is a signed binary so it can support UEFI Secure Boot. If you run grub2-install, a

Greetings - The short story is that got my new install completed with the partitioning I wanted and using software raid, but after a reboot I ended up with a grub prompt, and do not appear to have a grub.cfg file. So here is a little history of how I got here, because I know in order for anyone to help me they would subsequently ask for this information. So this post is a little long, but

Hello All Up until now we have been using standard PXE boot to do kick start installs of centos boxes. With recent machines however they come by default as EFI boot. We can set them to legacy but I would like to solve this before this option goes away. Just wondering if anyone has any experience setting up a net boot server that can be used to kickstart EFI machines? Thanks Grant
