similar to: Installing CentOS7 boot loader into the /boot partition

Hello Everyone, I am a newbie. When I try to install GRUB2 on centos 5.2 system, I get following error. centos5: grub-install /dev/sda //sbin/grub-setup: warn: This GPT partition label has no BIOS Boot Partition; embedding won't be possible!. //sbin/grub-setup: warn: Embedding is not possible. GRUB can only be installed in this setup by using blocklists. However, blocklists are UNRELIABLE

Hello, I am trying to build a PXE boot image for CentOS 7. livemedia-creator --make-pxe-live --ks=ks --no-virt It runs the entire process and then it says: losetup: /dev/: detach failed: Inappropriate ioctl for device 2019-12-26 11:49:47,293: Disk Image install successful 2019-12-26 11:49:47,293: working dir is /var/tmp/tmpKwqC77 mount: /dev/loop0 is write-protected, mounting read-only mount:

Hi all, I was using grub2 for booting Archlinux x86_64 in my GPT Internal HDD (/dev/sda) then I switched to syslinux/extlinux. It was working fine but suddenly it staring showing "Boot Error" message on screen. I googled for a solution and tried all syslinux versions from 4.04-pre4 down to 4.03-stable but non of them worked. I don't know what suddenly changed caused this

Hello Everyone, We have centos6 server. And we are planning to upgrade it to Centos7.And GRUB 2 needs a new bios grub partition. Creating a new partition is too much risky. I am wondering if it is possible to replace Grub2 with Grub legacy on Centos7 machine? Thanks!! Sachin

Do most people today have /boot on a separate partition, or do they (you) have it on the / partition ? -- Timothy Murphy gayleard /at/ eircom.net School of Mathematics, Trinity College, Dublin

Hello, I was looking for a way to detect the installed boot loader of an image and I found this: https://github.com/arvidjaar/bootinfoscript This script will inspection a lot of things on a running system and will output a Report. The most interesting part is that it uses known Master and Volume Boot Record byte-patterns to determine the installed boot loader:

Hello List, I'm ironing out details to upgrade a few systems to CentOS7. My servers have BMC with Serial over LAN support. In C5 and C6, I determined how to have BIOS/POST, kernel, and serial console access. I'm reading up on the method to accomplish the pieces with C7. Presently SoL output works, so I see BIOS/POST messages and the GRUB boot list. My changes to enable serial

Hi, When I perform a software RAID 1 or RAID 5 installation on a LAN server with several hard disks, I wonder if GRUB already gets installed on each individual MBR, or if I have to do that manually. On CentOS 5.x and 6.x, this had to be done like this: # grub grub> device (hd0) /dev/sda grub> device (hd1) /dev/sdb grub> root (hd0,0) grub> setup (hd0) grub> root (hd1,0) grub>

Question 1: has anyone used preupgrade (I used it with fc 17 -> 19, and it pretty much appeared to work, but that was on a couple of worksttions)? Opinions? Question 2: is grub still supported, or is there something that *FORCES* you to use grub2? mark "grub2 must DIE!"

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

Oh, alright my specific issue is just about creating the actual pxe image.. not what happens after -----Original Message----- From: CentOS <centos-bounces at centos.org> On Behalf Of R C Sent: Thursday, December 26, 2019 12:18 PM To: centos at centos.org Subject: Re: [CentOS] livemedia-creator --make-pxe-live CentOS 7 I have "issues" with later versions of Centos/RHEL 7 also.

Create an object hierarchy to represent different bootloaders for Linux guests, moving the separate handling of grub1 and grub2 in different classes: this isolates the code for each type of bootloader together, instead of scattering it all around. This is mostly code refactoring, with no actual behaviour change. --- po/POTFILES-ml | 1 + v2v/Makefile.am | 2 + v2v/bootloaders.ml
