I?ll explain what?s happening first, and list the steps after that. First: pep is short for the Xen target x86_64-pep. It?s a target you can enable when configuring Xen to create an EFI binary. What is happening with Xen on UEFI via Grub is that it doesn?t give the kernel any info on the ACPI root pointer. Basically, this means that Linux won?t be able to do ACPI, and therefore a ton of hardware

As an addition to anyone having issues with booting but only getting 1 CPU and a ton of devices that misbehave, check to see if you have an RSDP in Xen and Linux. You should have both (I use xl and not xm): sudo xl dmesg | grep RSDP (XEN) ACPI: RSDP DDA4A000, 0024 (r2 SUPERM) and sudo dmesg | grep RSDP [ 0.000000] ACPI: RSDP 00000000000f0010 000024 (v02 SUPERM) I?m running this on a

I have installed dom0 Wheezy 64 bit on Dell PowerEdge T310 with kernel from package and xen-unstable. System is in Uefi mode and booted with grub-efi-amd64. Booting without xen efibootmgr works, while with xen not, efivars kernel module is loaded but show this message: efibootmgr Fatal: Couldn''t open either sysfs or procfs directories for accessing EFI variables. Try ''modprobe

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

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

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

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
