I installed CentOS 7 on a Shuttle X27D box (dual-core Atom 330), and so far it seems to work fine, but it didn't set up a Grub2 entry for the existing Windows XP installation in the first partition (MBR). Running os-prober generates no output. fdisk shows that the NTFS partition is still present as /dev/sda1, and still has the bootable flag set. I added a menuentry for Windows to the end of

If this has already been done, please forgive me. However, if not, I''d like to submit this as a mechanism for generating a bootable grub2 stanza for hypervisors. As the /etc/grub.d/* files rely on defaults in /etc/default/grub, I added the following Xen specific variable: GRUB_CMDLINE_XEN_DEFAULT="console=com1 115200,8n1 dom0_mem=512M dom0_max_vcpus=1 dom0_vcpus_pin=true

I have a laptop with windows 10. I went into the Windows disk manager and shrunk the volume to make room for C7. That worked. I also changed the BIOS from secure boot to "both" (secure/legacy) I installed C7, went fine. About the time it was done I realized I never saw anything about "other" boot options (seems I saw that in the past). Anyway sure enough, got done and C7

Hello Xen folks, I use Debian Squeeze. I want to passthrough PCI devices. With the old stable Debian (grub legacy) i did not have problems. I edit /etc/default/grub like: quote: GRUB_CMDLINE_XEN_DEFAULT="quiet xen-pciback.permissive xen-pciback.hide=(00:14.2)(01:05.1)" I run "update-grub". Now i look at /boot/grub/grub.cfg: ### BEGIN /etc/grub.d/20_linux_xen

I am looking into setting up Xen 4.0 on a simple dual-boot Windows/ubuntu laptop with the following partitions: | Device Boot Start End Blocks Id System | /dev/sda1 * 1 223 1782784 7 HPFS/NTFS | /dev/sda2 223 21713 172624888 7 HPFS/NTFS | /dev/sda3 35854 38914 24576344 7 HPFS/NTFS | /dev/sda4

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

I've been trying to use memdisk with grub2 to boot some iso images -( I've done this without any problem with pxe ) There is a memdisk.mod in /boot/grub/ and I've seen some material talking about this, but no example of a menu. After trying countless permutations - Right now I have : menuentry "Memtest-Plus 4.2" { echo `hello` insmod lvm

Hello, I have installed the Xen 4.1.1 and a working kernel 2.6.32.43 which supports Xen on a Ubuntu Linux 10.04 LTS. However, I have never successfully booted the Hypervisor and Dom0. The screen is always black after some kernel messages rapidly go by. I think that I may pass the wrong parameters to the kernel or Hypervisor with GRUB2. Can any one share his/her working grub.cfg for GRUB2 with

Hello, I compiled xen on ubuntu, but at the bot i got the kernel panic message. I enabled the support to ext4 fs. This is kernel panic error: EXT3-fs: unable to read superblock ETX4-fs (md0): unable to read superblock FAT: unable to read boot vector Kernel panic - not syncing: VFS: Unable to read superblock(9,8) My grub.cfg generated by update-grup: menuentry ''Ubuntu, with Linux

I recently updated the kernel on an Ubuntu 11.04 PVM domU. The dom0 is an up to date Debian Squeeze host (Xen 4.0.1). Attempting to start the domU after this with xm create gives "Error: Boot loader didn''t return any data!". I ran pygrub against the domU manually, I got the following: Traceback (most recent call last): File "/usr/lib/xen-default/bin/pygrub", line

Hello, I'm having a problem booting a compressed ISO image using memdisk via grub2 (version 2.02). The entry in my grub.cfg looks like: menuentry 'boot ISO image' { linux16 /memdisk iso initrd16 /my-image.iso.gz } When selected, this starts to boot and then fails with: Ramdisk at 0x37979000, length 0x0033b298 gzip image: decompressed addr 0x7f7f7000, len

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. If the subvolume name is known. should grub2 be able to

I had CentOS 6 installed on an MBR hard disk. I converted the disk to GPT (with UEFI) and installed CentOS 7 on a new partition. CentOS 7 itself seems to work properly. Grub from CentOS 7 automatically created an entry for CentOS 6, but I get an error if I try to boot CentOS 6. The menu entry is: menuentry 'CentOS release 6.10 (Final) (on /dev/sda7)' --class gnu-linux --class gnu
