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

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

Apologies if this has been gone over, but I believe I have checked the intertubes more than a bit..... I am using libvirt and have vms booting under an OVMF.fd to use an efi firmware. I can create vms, linux ubuntu, and they will boot up. However, everytime I reboot am I dropped into the default efi shell provide by the tianocore build. Then I must walk the FS to the booting efi app and run, in

I have not looked into it all that much. But seems that UEFI basically allows booting without a bootloader. Here is some gentoo wiki info in it: http://wiki.gentoo.org/wiki/EFI_stub_kernel And Greg Kroah-Hartman talking about it a bit: http://kroah.com/log/blog/2013/09/02/booting-a-self-signed-linux-kernel/ I am looking forward to making a little HOWTO, for this subject and also for using

Thanks VERY MUCH for all the info and help! Apologies for the extreme delay. I got distracted by other threads that forced out this work to later date. Also some frustration as well. ;) I completely missed this update. Apologies and thanks Will be diving back into this shortly!

Ady, Thanks for taking the time to respond to my lengthy post.

Morning all, I have a HP Envy dual boot system (Win8 for serious stuff, i.e. Train Sim and Flight Sim) and Centos 7 for everything else. In the past I've had the occasional problem where an update on the windows side has updated the UEFI boot sequence but using efibootmgr has always fixed it. On Friday I discovered that my HDD was failing so I tried using Clonezilla to move it on to a new

All of the following is still under the Centos 7 KDE Live CD: If I mount /dev/sda2 on /media and have a look, this is the valid EFI filesystem, including the Fedora and Centos entries. If I try to mount /dev/sda6 on /media it looks to be a valid /boot filesystem. If I mount /dev/sda6 as /boot and mount /dev/sda2 as /boot/efi before running Jim's efibootmgr command will I fix the problem

I had to boot my HP Envy into Win8 for the first time in ages this morning. When I did that, it installed some updates including a BIOS update. Once this was all done, once again the GRUB boot menu was gone and it booted straight into Win8. Using the advanced boot manager options in Win8 I managed to get the EFI boot menu up and chose Ferdora 21. It was only after Fedora failed to boot that

OK, I wanted to replace the 500G disks in a Dell T20 server with new 2TB disks. The machine has 4 SATA ports, one used for the optical disk and three for the hard drives. It is set up with /dev/sda and /dev/sdb with each three partitions: 1 -- VFAT (for EFI) 2 -- ext4 (for /boot) 3 -- LVM /dev/sda2 and /dev/sdb2 are a mirror raid (/dev/md0) /dev/sda3 and /dev/sdb3 are a mirror raid

Internet reports that I'm 1-of-many victims, failing to run linux on new/cheap laptops. Eg. quad-Atom; connex L1470. What is syslinux's recomended method to overcome <WinTel's UEFI lockout> using a USBbootStik ? Are wifi drivers: RTL8723BS for linux available yet ? ==TIA.

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.

Hi, I am trying to get a UEFI bootable USB. And I am unable to make it working. I have two x86_64 systems and both of them 'hangs' when I choose to boot UEFI from USB. I've created fat32 formated partition with ef00 type. I placed EFI/BOOT there with content of efi64/ distribution, I've created syslinux.cfg and renamed syslinux.efi to BOOTX64.EFI. However, it does just

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
