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

Sysinux 6 will not boot ISOs on BIOS (i.e. pre-UEFI) systems
It occured with every BIOS system I tested on (none of them Dell):
1. HP G62 laptop (i3)
2. Samsung RV520 (i3)
Don't know what system Philip Muller uses; have copied him in as he has far
more technical knowledge than I do. Syslinux tested from Arch and Manjaro
(an Arch derivative). Basically found then when creating latest ISO images.
I may be missing something as well about the FMs. Just

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.

rescue - UEFI revert to BIOS boot - how?
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.

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

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

HP Envy EFI problem after BIOS update
Hi Jim,
Thanks for this. I looked into what you said, and once happy I ran the
command you gave. It appeared to work as it did not come up with any errors,
and the output from efibootmgr showed
1) Centos had been added as an option and
2) it was the first in the boot sequence.
However, when I rebooted the laptop went straight into Win8, and after
rebooting back into KDE Live, the option is

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

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

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
