I didn't find any documentation on the syslinux page for "linuxefi" command -
where is this documented?
Or is there a "default" syslinux.cfg for efi that I could use as a template?
I also moved the iramfs.gz to the separate INITRD command - still no change.
Any further hints? How can I debug this?

Booting CentOS 6 with Grub from CentOS 7
...rd_NO_MD LANG=fr_FR.UTF-8

initrd /boot/initramfs-2.6.32-754.3.5.el6.centos.plus.x86_64.img
}
When I try to boot, I get a message that "linux" and "initrd" aren't
valid commands. If I change them to "linuxefi" and initrdefi", I get
this error:
error: kernel too old
error: you need to load the kernel first
The information in the entry seems correct (partition, UUID, etc.).
I've searched on Google quite a bit, but didn't find anything useful.
Are there any suggestions?

Boot Loop in efi
Hi all,
I did my first steps on syslinux 6.03 with EFI...
I prepared the disk with GPT, EFI system partition and formatted it FAT32.
I added the files to EFI/BOOT including the syslinux libraries and syslinux.cfg
The system starts booting, loads kernel and initrd (I see the loading output on
the screen), but then the system resets and the loop restarts (infinitely).
I took the same

Weird results from g.sh()

power
It seems that g.ls('/sys') is chrooted correctly.
But g.sh('ls /sys') isn't.
I came across this behavior when I used g.command(['grub2-mkconfig', '-o',
'....']) on rhel7.8 and it didn't produce the correct linuxefi/initrdefi
entries in grub, since in rhel7.8 the uefi detection algorithm is checking
in bash '[ -d /sys/firmware/efi ]'.

EFI PXE Server - pxelinux.0 equivalent?
Hi all - I'm not sure if it's appropriate to ask this here, but I
don't see this question explicitly answered anywhere.
Is there an EFI version of "pxelinux.0" that will function basically
the same way and read the same pxelinux.cfg/default menu files?
I've got a really dodgy grubx64.efi EFI PXE menu up at work, but it
can't load the 1.2 gigabyte LiveCD that we use

Boot Loop in efi
...ooting page?:
https://wiki.syslinux.org/wiki/index.php?title=Common_Problems
In particular, there is a section at the end that looks similar to your
problem.
I'm not familiar with the problem. You might try some variations on the
command you are using to load the kernel (e.g. try using "linuxefi" instead
of the "linux" or "kernel" command).

[CentOS] boot thumbdrive with CentOS 7 ISO???
...d ^X can be used to 'edit' and 'execute' boot statements, none of
which works correctly or is obvious what to alter or enter.
I also got into an interface with a 'grub>' prompt. I tried some of the
grub commands, but had little clue what to do with that. E.g.,
"linuxefi /isolinux/isolinux.bin" returned "error: invalid magic
number." Interesting, but not getting CentOS 7 booted.
Any know what else is possible?

(Solved) Booting CentOS 6 with Grub from CentOS 7
...too old, but the latest centosplus kernel for CentOS
6, vmlinuz-2.6.32-754.3.5.el6.centos.plus.x86_64, apparently
qualifies.
The solution was to install the latest kernel-ml kernel from ELRepo,
https://elrepo.org/ , to change grub.cfg to reflect the new versions,
and to change linux and initrd to linuxefi and initrdefi.
I'm surprised this has apparently never arisen before. Am I really the
first person to dual-boot CentOS 6 and 7?
Thanks to Lingzhu Xiang for his bug report,
https://bugzilla.redhat.com/show_bug.cgi?id=894300 , which put me on
the right track.

UEFI and PXE
...They are all identical to the installed one (distributed with grub).
I'm tantalizingly close. CentOS6 UEFI PXE is working, but the machine won't boot.
It is best to use the CentOS7 BOOTX64.EFI loader. The "kernel too old" message is due to the fact that the PXE config file uses linuxefi and initrdefi directives. They need to be changed to linux/initrd, respectively. linux16/initrd16 may also work. The arguments to those directives need to adhere to CentOS6 legacy grub syntax (ks instead of inst.ks etc.).
This will cause error messages on the client that both linux and initrd are...

I can see the DHCP request at PXE boot time, and it works, but none

My grub2-btrfs & yum-plugin-snapper
...ned to me once grub.cfg 1.1MB was large, on fedora.
If Grub2 is so installed that it looks for strange systems, a yum
installation, because of grub2-mkconfig, also take a long time.
It works as it is. The grub2 plugin needs a little bit work. But now
analyse jet.
I made ist failsafe for linux and linuxefi.
For me, it was important to know whether such a thing under centos
works, because yum-plugin-fs-snapshot is intended for several file
systems. Can be helpful or not. Just something different for me.
Fun work :-)
