So, it installed happily. Then wouldn't boot. No problem, I'll bring it up with pxe, then chroot and grub2-install. Um, nope. I edited the device map from hd0 and hd1 being the RAID to /dev/sda and /dev/sdb, then ran grup2-install. It now tells me can't identify the filesystem on hd0, and can't perform a safety check, and gives up. What am I missing? Google is not giving me any

Here is a patch that makes it possible to chainload GRUB2 core.img form chain.c32. It reuses the grub= parameter (used for chainloading GRUB Legacy stage2): - both loaded at 0x8000 - start execution at offset 0x200 (0x8200 in memory) GRUB2 allows to specify another "GRUB home dir" than the standard /boot/grub GRUB2 doesn't allow to change the configfile 'grub.cfg' name

Hello Erwan and others, I am running HDT from grub2 with memdisk. I have informed the success of booting hdt to the grub2 list. Some developers are very much interested to this issue and they are showing their interest to make a glue between com32 and grub2 so that hdt can be loaded without memdisk. It is really very exciting to have hdt as an inbuilt feature of grub2. Could any one kindly

Hello All, I am trying to set multiple users with passwords for modifying grub2 menu entries at boot. I know I can set a "root" user grub2 password with grub2-setpassword. I have also been able to make a grub2 user password using the grub2-mkpasswd-pbkdf2 command and adding ??? set superusers="user1" to the /etc/grub.d/40_custom file. However, I have multiple user

There is some interest lately in making a self-contained grub2 boot image - call it pvgrub2, used for booting paravirtual domU in xen where a grub2 config is installed. First attempt------------------ I first tried using the grub2*.src.rpm from the C7 vault. I configured as shown belowhttps://blog.xenproject.org/2015/01/07/using-grub-2-as-a-bootloader-for-xen-pv-guests/ for headers, I used

I have RHEL 7 Beta installed in dual boot with CentOS 6.x. Since RHEL 7 installed GRUB2, I had problem that RHEL 7 is default boot. My personal solution was to go to /etc/grub.d and run command: mv 10_linux 31_linux grub2-mkconfig -o /boot/grub2/grub.cfg Explanation: - /etc/grub.d is where grub2 writes down config files used to create boot menu. - OS-prober creates 30_os-prober file in

Good afternoon from Singapore, I need SERIOUS help on GRUB in CentOS 7.5 1804. Please refer to my installation notes at?http://lists.linuxfromscratch.org/pipermail/lfs-chat/2018-October/028964.html According to Petros' instructions, I need GRUB Legacy 0.97 for my Extremely Simple Linux. But GRUB Legacy 0.97 has been deprecated in CentOS 7.5. GRUB2 is installed by default on CentOS 7.5. So

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

So I installed centos8. And I was looking for the grub config file: [root at testbox ~]# ls -l /etc/grub2.cfg lrwxrwxrwx. 1 root root 22 Oct 2 13:01 /etc/grub2.cfg -> ../boot/grub2/grub.cfg [root at testbox ~]# But [root at testbox ~]# ls /boot/grub2/ grubenv [root at testbox ~]# Why is it not there? FYI, I did try 'yum reinstall grub2' and no /boot/grub2/grub.cfg for me.

Hello, I have the following scenario: - GPT Partitioned USB disk with syslinux (or extlinux) on the first partition and a menu to boot each partition; all of them are iso9660 images of different linux distros, - Before dumping every iso image into its partition space on the USB disk I need to remaster it changing something on its initrd to be able to coexist with other linux distros on the

Hi list, What is the best method to migrate Hyper-V 2012 VM to oVirt/RHEV ? I made a v2v livecd, but it never load consoles and never launch p2v service (works well with BIOS VM or hardware, but G2 HyperV VM needs EFI to boot). I must add some packages on my system to build an EL7 (kmod-hfsplus from elrepo) and some other to boot on EFI : #boot EFI grub2 grub2-efi grub2-efi-modules
