I never thought I'd say this, but I think it's easier to do this with GRUB 2. Anyway I did an installation to raid1's in CentOS 6's installer, which still uses GRUB legacy. I tested removing each of the two devices and it still boots. These are the commands in its log: : Running... ['/sbin/grub-install', '--just-copy'] : Running... ['/sbin...

This patch set should make it easier to maintain PV-GRUB2 installations. The general idea is based on discussions I had with Xen developers (mainly Ian Jackson) at the Ubuntu Developer Summit in May 2011; though I never did manage to get the core port done and Vladimir beat me to that, I think the configuration approach we discussed there is still valid...

Hi Colin, Thanks for the quick reply.

...ular Syslinux? Are they not > in the ISO? It's probably best to use a real-life example for that, so, since I was talking about tails before, I'm going to use the tails-i386-2.0.1.iso to illustrate what I'm currently doing in Rufus. I'll skip the EFI part of tails (that uses grub/EFI) to talk only about the BIOS/Syslinux part. If you look at the /isolinux/ directory from that ISO (the content of which you can also see in the attached log), you see that it contains an 'isolinux.bin', along with an 'isolinux.cfg' as well as a set of modules, including '...

Hi Debian Grub maintainer, In december, Xen PVH support has been committed in grub master: https://www.mail-archive.com/grub-devel at gnu.org/msg28125.html The last pieces needed in the Linux kernel to boot PVH with grub2 landed in Linux 4.20. I asked our kernel team to carry those patches on top of the Linux 4...

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...

Confirmed this issue. To reproduce: Install a fresh Wheezy AMD64 guest under Xen 4.1 (hypervirtualized, boot from the debian-7.1.0-amd64-CD-1.iso). Use "entire disk" automatic layout for partitioning, this creates /dev/xvda1 for / and /dev/xvda5 for swap. It will create /boot/grub/grub.cfg with many references to (/dev/xvda,msdos1) which works fine when the machine is booted hypervirtualized. PyGrub can not handle the /dev/ syntax for devices, even though Grub can. My details: Package: xen-utils-4.1 Version: 4.1.4-3+deb7u1 Architecture: amd64 Confirmed workaround: inside...

...I have a system with two disks, where device.map labels one as hd0 and the other as hd1, and I swap those numbers, the resulting boot sector will differ by one bit. My understanding was that those IDs are used to map to the BIOS disk ID. Stage 2 will be read from the partition specified to the grub installer at installation, as in: grub> install --stage2=/boot/grub/stage2 /grub/stage1 d (hd0,1)/grub/stage2 p (hd0,1)/grub/grub.conf Stage 1 and 1.5 will, as far as I know, always be on (hd0), but stage2 might not be. If the BIOS device IDs specified in device.map weren't written int...

Background: I am in the habit of making bootable GRUB CDs with menus and copies of working kernels and initrds, particularly for multiple-boot testing machines with multiple distros and/or the Redmond OS. This has helped pull my fat out of the fire more than once when a system was rendered unbootable by hardware changes, or when Bill Gates decided th...

doing that grub-install /dev/sda will give me the "corresponding BIOS device" error. But now I fixed it by doing a manual grub install. first boot with cd1 and type linux rescue at the prompt when you're at the linux prompt after detecting and mounting the partitions, do a "chroot /mnt/sysimag...

Paths in grub.conf are relative to the filesystem containing it. grub parsing currently assumes that it is on /boot, and will fail if it isn't, for example because a guest only has a single partition. This patch makes grub parsing work harder to work out what grub paths are relative to. Firstly, it looks fo...

From: Pavel Butsykin <pbutsykin@virtuozzo.com> This patch improves the search of grub config on EFI partition. This means that the config will be found not only for rhel but also for many other distributions. Tests were performed on the following distributions: centos, fedora, ubuntu, suse. In all cases, the config path was /boot/efi/EFI/*distname*/grub.cfg The main purpose of the...

As of the latest updates to anaconda and grub2 for Fedora 18, it is now possible to install with /boot as a btrfs subvolume. The way that grub2 is handling this is the "reach down" to the files it needs as if the subvolume was a directory. Is this OK? At this point I am not worried about snapshots or any other complexities. I...
