8.2.2004 Latest yum update renders machine unbootable
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

Re-enable grub boot in UEFI (Windows took over it)
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.

uefi built from tiancore via edk2 can't persist boot changes
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

Even more (U)EFI questions
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:

And Greg Kroah-Hartman talking about it a bit:

Re: uefi built from tiancore via edk2 can't persist boot changes
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!

UEFI boot manager sequence problems HP Envy
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

HP Envy EFI problem after BIOS update
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

HP Envy EFI problem after BIOS update
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

CentOS6: HELP! EFI boot fails after replacing disks...
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

Wave of <elCheapo Wintel> Laptops.
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 ?

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 -

boot from tradition BIOS?
many thanks, L.

Unable to get syslinux.efi to work, grub2 boots tho
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

Xen EFI boot how to?
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.
