Grub Boot Loader

Does anyone know where I can find all the parameters and switches that are available for the Grub boot loader. I want to trim the boot parameters because I am on the lowest end of the memory requirement and Solaris won;t install because of that.
Thanks in advance
RonM

Here's the manual for Grub which contains all of the commands and configurations...

  • Cant install grub boot loader

    Hi. just recently I decided to try out arch linux. I have heard great things about this distribution, but havent been able to try it out. several times i have followed extensive guides on installing arch linux but have always gotten stuck at installing the grub boot loader. it gives an error mesage saying that embedding isnt possible with ext2 filesystem, at no instance have i used the ext2 filesystem. what am i missing? any help willl be greatly appreciated.

    dgre6133, you should chroot into the system and check the logs. It is better to provide actual error output. Are you sure it was hex?
    You need to boot back into the install medium. Then, mount the partitions and chroot in, similar to what you did during install. Read up on chroot in the wiki if you have questions. Once you do this, check the logs and give us the actual error messages. Also, post /etc/fstab and the output of
    lsblk -f
    edit: post the grub configuration as well, grub.cfg   (post 420.....smirk)
    Edit2: Also, you've managed to install Grub, so you might want to end this thread as solved and split this new error off into its own thread. Report the new problem post to a moderator with this request if you want to do that.

  • Error installing grub boot loader

    I am currently following the beginner guide for installing arch, and once I get to the place where I need to install a boot loader and use the command pacman -S grub-bios, I get a seemingly never ending output of "sh: /usr/bin/wget: no such file or directory" then it will change to "warning: failed to retrieve some files from core"(more like all files lol) etc as it goes through the repos. I've followed the guide to a tee, with the exception of the example partitioning on there. Anyone have any ideas on what could be going wrong?

    It seems like wget is missing on the install partition. This is after you have done arch-chroot right?
    I would try to do a
    # pacman -Syy wget
    to update the archive and install wget
    and then try grub-bios again
    edit:
    If you are still on the install media the command you want to use is
    # pacstrap /mnt grub-bios

  • Arch & Windows 8 Dual Boot -- Windows Boot Loader loads grub-rescue

    Arch works fine,but as it always happens Windows boot went down. Both OS are EFI.
    Note that boot secure and fast boot were disabled for Windows 8.
    I used os-prober, but did not fix anything; so, I removed it. I tried to hack things out using boot-repair from Ubuntu, but it requires a repository, grub-efi, from Ubuntu that Arch doesn't have.
    I am trying to modify files in grub.d and grub.cfg and hopefully fix something.
    Exact description:
    - archgrub loads and shows 3 entries. Two for Arch that load the sys succesfully and one for Windows 8 that fails.
    - When I try to execute Windows from grub, it brings me to a grub rescue>
      and shows error /boot/grub/x86_64-efi/normal.mod not found
      As far as I am concerned this .mod is from Linux, so I don't know why it is being called into Windows loading procedures.
    lsblk returns:

    Hi,
    New to this forum, joined today in anticipation of trying an install of AL...For whatever this may be worth:
    I have an HP Pavillion desktop that came with Windows 8 (now 8.1), & has, of course, a UEFI boot system. I tried earlier to install Ubuntu Studio (which I currently run) on the same disk as Windows (/dev/sda), I made (I believe) a huge mistake in trying to install as LVM/ext4... wiped out my Windows install & made the UEFI unavailable... I had to do a complete re-install of Windows (fortunately, I did the recommended system backup, using 4 DVD's!) so then I tried a (non LVM) install on an external usb 3.0, with the Grub 2 on the external disk (great access time, & it worked fine...  IMO)...
    One other item: as I have been trying to find the right flavor of Linux for my main purposes, I have been trying various distros. & having to try to learn to negotiate the UEFI, secure/legacy procedures (still learning)... As I was unsure of installing rEFind... I did down load the .iso, burn it to a CD...
    http://www.rodsbooks.com/refind/getting.html
    & in  legacy mode, found that simply putting it (rEFind CD into the CD/DVD player, which in the UEFI it is labeled something like HP/UEFI CD/DVD), & then launching it, rEFind worked for some other distros...that is, I was able to boot into my Linux distros, even bypassing Grub), as well as having the option of booting Windows. It may seem trivial that I say this (it maybe is), but I have not seen anywhere (I have scoured the internet rather well) this mentioned as a possibility (though it, of course, would not make such a good permanent solution, especially for computers like mine that have only one CD/DVD player).

  • Boot Loader Problem(rEFIt & GRUB/LILO)

    Hi,
    I'm planning to "triple boot" my iMac with "Mac SL, Win 7, & openSUSE". But installing the "GRUB/LILO" makes my origanel boot loader rEFIt cannot work directly.
    I have to select "Win 7/openSUSE" from the rEFIt, and select "WIn 7/openSUSE" again (from GRUB/LILO).
    Any suggestion for fixing the problerm so I can boot straight to the OSes?
    Thanks.

    Boot from the solaris dvd in to singe user mode, mount the system under /a and run the instalgrub command in the shell:
    /sbin/installgrub -m /boot/grub/stage1 /boot/grub/stage2 /dev/rdsk/c?d?s? (whatever your drive is).
    Maybe make a backup copy of /a/boot/grub/menu.lst, I cant remember if it gets over written that way you can copy it back if necessary.

    This is a clean install using April 01 ISO with minimal or no modifications. I have tried to follow wiki as precisely as possible. I am not sure what I am missing. Thanks.
    EDIT1: Updated and cleaned the post to better reflect current structure and added /etc/fstab.
    EDIT2: @swordfish Removed /boot/EFI/arch.

    I used March ISO instead of April ISO and it worked flawlessly. There is some problem with April ISO where efibootmgr and UEFI Shell1/2 fail with ASSERT_EFI_ERROR (status = device error).
    I have removed both /boot/EFI/boot and /boot/EFI/arch. I now have two entries one on vmlinuz-linux on 1024 Fat 32 partition which works and second one boot/vmlinuz-linux on 20G / partition which fails and takes me to rootfs. Also refind isn't showing UEFI shells that  I have in /boot/EFI/tools/Shells.

    Thanks for suggesting to try older ISO.
    UPDATE:- Most recent ls -R /boot and my refind.conf. Reading over Rod Smith's rEFInd documentation has helped me clean up a little more and set up a good boot manager with automatic kernel detection and shell. I do want to get rid of drivers list that shows itself up along with kernel. Next is to tackle menu entry. Thanks.

  • Xen / pygrub issues: VmError: Boot loader didn't return any data!

    Hardware:
    2x Intel Xeon Quad-Core 2.33GHz
    24GB FBDIMM RAM
    2x 2TB HDD in RAID-1
    Intel Server Board S5400SF
    Setup:
    Arch Linux x86_64
    Xen 4.1.2
    Grub2 Multiboot
    Synopsis:
    I set up a new VM for Debian Squeeze following instructions here: http://www.howtoforge.com/installing-de … 86_64-dom0. Partitioning & installation completed correctly. When I tried to run the VPS afterwards, I got this output:
    | [root@srv0 xen]# xm create -c /etc/xen/xm-debian.cfg
    | Using config file "/etc/xen/xm-debian.cfg".
    | Error: Boot loader didn't return any data!
    I've attached a more complete log output at the end of the mail.
    This is the first VM I have tried to create on this setup.
    Additional:
    I can mount the partition within the lvm:
    | [root@srv0 xen]# kpartx -av /dev/VPS/fennec
    | add map VPS-fennec1 (253:2): 0 83881984 linear /dev/VPS/fennec 2048

    Hi,
    I have a very similar issue. I've managed to create PVM guests under 3.0.1 and upgraded via YUM to 3.0.3. I now have 2 Hosts and created a guest Server that I downloaded from the Oracle Software Cloud. This boots fine and is accessible. I cannot create a standalone guest (I want to create a RHEL 5 Server) as this gives me the same error. The Server Pool has one Server Pool LUN and one Repo for the Guests.
    I can create the guest and and add a small boot ISO from the ISO Repositiory, which I then intent to Kickstart the rest of the installation. When starting the Guest, the following is received:
    Starting operation 'Virtual Machine Start' on object '0004fb0000060000951b61a25a250dc9 (csitestvl14)'

  • Installing JUST the boot loader

    experimenting with a few things and am looking to figure out how I can JUST install the boot loader.... via the ISO, it requires me to do all the steps before it (installing packages, partitioning, etc before I can install the boot loader.  I'm looking for a way to essentially detect what's already there and skip all the other portions of the install process to JUST install the boot loader... anyone have any ideas where I can start?  Searching the forums has not produced the specific thing I'm looking to do.  A lot of stuff coverd about the bootloader in general, but not standalone installation of such.  Thanks in advance!!!

    That will install grub to the MBR of hdx - you can also install grub to a partition if you want.  See the grub wiki page.
    Isn't that exactly what my line does? (grub-install --root-directory=/mnt /dev/sda)
    @cpunltd: You have to mount a partition because Grub needs to know where to find the menu.lst and its other files. The package "grub" needs to be installed on /dev/sda1 in my example.

  • Arch - Boot loader installation failed

    I was trying to install Arch from my USB drive...I had booted off the Live USB (non persistent) and gone thru the arch setup as "root".
    I followed all the steps ...When I come to the penultimate step - "Install Boot Loader",
    I am taken to a screen wherein I have to choose between GRUB or nothing
    I chose GRUB and it asks me to install in MBR or other partition
    Initially I gave root partition (/dev/sda7) ...I got the foll errors
    1.Bootloader installation failed
    2.Error mounting /dev/sda7
    3.Check /dev/tty7 for details..I am not able to access tty7 and I get error device does not exist
    I also tried installing in MBR but does not go thru
    Any pointers?

    Good idea to read this

  • [solved] Bootloaders (syslinux/Grub) not loading on new installation

    Hi,
    I´m trying to install arch on a Lenovo Thinkpad X1 (UEFI). I installed grub as described in the wiki, but grub does not start up at all when the machine is powered on. sda is partitioned (GPT) as follows:
    1. 512 MB: ESP (EF00) = sda1
    2. remaining space: LVM (8E00)
    a.) boot (300 MB)
    b.) Swap (4 GB)
    c.) root (25 GB)
    d.) home (remaining space)
    fstab:
    LABEL=root / ext4 rw,relatime,data=ordered 0 1
    LABEL=home /home ext4 rw,relatime,data=ordered 0 2
    LABEL=boot /boot ext4 rw,relatime,data=ordered 0 2
    /dev/sda1 /boot/efi vfat rw,relatime,fmask=0022,codepage=437;iocharset=iso8859-1,shortname=mixed,errors=remount-ro 0 2
    /dev/mapper/lvm-spwap none swap defaults 0 0
    I installed grub via
    grub-install --target=x86_64-efi --efi-directory=/boot/efi --bootloader-id=arch_grub --recheck --debug
    No errors were reported, x86_64-efi is now present in /boot/grub. /boot/efi is now populated by the folder EFI/arch_grub, which contains grubx64.efi
    grub.cfg was generated within the chroot by
    grub-mkconfig -o /boot/grub/grub.cfg
    This command gives somes warnings:
    WARNING: Failed to connect to lvmetad: No such file or directory. Falling back to internal scanning.
    /run/lvm/lvmetad.socket: connect failed: No such file or directory
    done
    If I try to activate lvmetad.service by systemctl I get the error:
    Running in chroot, ignoring request.
    Leaving the chroot (lvmetad is running), 'grub-mkconfig -o /mnt/boot/grub/grub.cfg' results in:
    Generating grub configuration file ...
    Found memtest86+ image: /boot/memtest86+/memtest.bin
    /usr/bin/grub-probe: warning:unknown device type dm-0
    done
    After rebooting I just get a blank screen, grub is not loading at all. I have absolutely no idea, what went wrong during the installation, therefore I would be glad if you gave me some input. Thanks!
    EDIT: I just installed arch with the legacy BIOS enabled instead of UEFI. The problem is very similar with this configuration. Instead of a loaded Grub I only get a blinking cursor.

    Yes, sdb is a gpt disk. It was partitioned with gdisk. Actually the gpt format is the only thing, which all variants tested had in common.
    To sum it up: Regardless of using bios legacy or UEFI, I am not able to start a boot loader (tested syslinux, grub) when the machine is powered on. I only get a black screen.
    EDIT: I have to apologize. I did a fresh install on the system with UEFI enabled, now syslinux is showing up (most likely because edited /boot/efi/EFI/syslinux/syslinux.cfg and not /boot/syslinux/syslinux.cfg :-) ). Nevertheless, syslinux can´t boot arch because of:
    ../../../../vmlinuz-linux... failed: No such file or directory
    vmlinuz-linux and initramfs-linux.img are present in /boot.
    My /boot/efi/EFI/syslinux/syslinux.cfg looks like:
    UI menu.c32
    PROMPT 0
    MENU TITLE Boot Menu
    TIMEOUT 50
    DEFAULT arch
    LABEL arch
    MENU LABEL Arch Linux
    LINUX ../../../../vmlinuz-linux
    APPEND root=/dev/sda2 rw
    INITRD ../../../../initramfs-linux.img
    LABEL archfallback
    MENU LABEL Arch Linux Fallback
    LINUX ../../../../vmlinuz-linux
    APPEND root=/dev/sda2 rw
    INITRD ../../../../initramfs-linux-fallback.img
    I have to say that I created a separted boot partition:

  • Grub not loading on UEFI/GPT install

    I’m doing an arch install onto my new SSD and everything has gone smoothly until it’s time to boot into the freshly installed system. The install was done booting the install media in EFI mode (confirmed with efivars), and using grub as the bootloader. The new install shows up in the motherboard boot options (I named it ‘grub’), but selecting it results in a black screen with blinking cursor. If my drive with a windows install is connected, it uses that instead.
    There were no errors reported during grub install.
    Any tips for figuring out what's going on? There are a few other posts with similar problems but nothing that seems to be exactly my situation. It's tricky not getting any error messages or anything.
    Thanks
    Edit: I just remembered that I had trouble booting the install media in EFI mode until I followed the instruction in this thread. The problem now is not throwing the same error, but it strikes me that it could be related.
    Motherboard: MSI P67A-GD65
    Samsung 840 EVO partitioned (GPT) as follows:
    /dev/sda1
    512M
    Type “EFI System Partition”
    FAT32
    'boot', 'esp' flags
    /dev/sda2
    ~100G
    Type “Linux Filesystem"
    ext4 on LUKS (mapped to /dev/mapper/cryptroot)

    I don't believe this MB has secureboot features, at least not that I've been able to find.
    In the thread I mentioned the only thing I followed was the conlusion at the top:
    SOLUTION: Mount the USB flash drive's ESP and copy EFI/BOOT/loader.efi to EFI/BOOT/bootx64.efi, overwriting the original file.
    This was the install procedure:
    Partitions created with cfdisk
    cryptsetup luksOpen -s 512 /dev/sda2 cryptroot
    mkfs -t ext4 /dev/mapper cryptroot
    mkfs.vfat -F32 /dev/sda1
    mount /dev/mapper/cryptroot /mnt
    mkdir /mnt/boot
    mount /dev/sda1 /mnt/boot
    pacstrap -i /mnt base base-devel
    genfstab -U -p /mnt >> /mnt/etc/fstab
    arch-chroot /mnt /bin/bash
    Setup locale, passwd etc.
    Added encrypt hook to mkinitcpio.conf before filesystems
    mkinitcpio -p linux
    pacman -S grub efibootmgr
    grub-install --target=x86_64-efi --efi-directory=/boot --bootloader-id=grub_uefi --recheck

  • How do I create an x86 grub boot floppy from a Sparc system

    I inherited a well equipped SunFire v20z system that had been running Linux but removed by the donor of the machine. I would like to install Solaris-10 over my network but don't seem to be able to create a grub boot floppy since installgrub is an x86 executable and all I have is Sparc machines. Is there a way I can obtain a dd image of a boot floppy that I can put down on one of my Ultra-10's, modify it with the appropriate grub files and then boot it to install Solaris?
    Any alternate suggestions are welcome as well.
    Thanks in advance.......

  • Bootcamp not showing up in boot loader

    Today I needed to resize my Windows Vista Ultimate partition for work, so I used Disk Utility to crate an image from the partition. After that I used Boot Camp Assistant to remove the partition, and then create a larger partition. After this was done I went back into Disk Utility and restored the partition using the image I created earlier.
    In OS X I can mount the partition and access the files and it seems everything was restored correctly. When I restart my machine and hold down the Option key to bring up the boot loader, Bootcamp is no longer an option. The only partition I can boot from is HD.
    Please help! Thanks

    Did you actually Install a version of Windows into that Boot Camp Partition? It doesn't sound like you did.
    You'll need a copy of Windows 7 or 8, 64bit, and a valid license key code for whatever version you plan on installing.

  • Cannot mount Windows partition with boot loader on Mac OS 10.8

    I took out my hard drive of my Windows 7 PC, which has 3 partitions on it: C drive which contains the OS and the boot loader that the computer boots into, D drive which contains my data, and a third called "System Reserved" a few megabyte in size that I have no idea what so ever what it does besides that I cannot modify or delete it, which probably means that it is important.  Now I put the hard drive inside an USB 3.0 enclosure and I am trying to mount this hard drive onto my OS X Lion Macbook air.  Something strange is happening, in that the computer takes about 30 seconds or more to detect the drives presence, and then it just freezes after that.  On the initial try, the system actually successfully launched DiskUtility, and I can see the drive mounted in the list of detected drives and 3 partitions "SD1, SD2, SD3" under that drive, but after  repeating the procedure a few more times, nothing seems to be happening after the system freeze.
    Anyone have any idea what's going on?  I am trying to access the data partition for my stuff.
    I have Tuxera NTFS installed, and I should probably also mention that my Macbook Air is mid 2011 with only USB 2.0 ports.
         Thanks in advance.

    Ok, I figured out the freezing part; apparently, I had to connect to the USB port on the left side next to the power supply or the disk does not have enough power and causes the system to crash.  So, now Disk Utility can see the hard drive with no problem.
    But now, the partitions are detected as XFAT format and no volumes are mounted to the desktop.  Disk Utility displays the disk description as:
      Disk Description : INTEL SS DSA2M160G2GC Media  Total Capacity : 160.04 GB (160,041,885,696 Bytes)
      Connection Bus : USB  Write Status : Read/Write
      Connection Type : External  S.M.A.R.T. Status : Not Supported
      USB Serial Number : CVPO049000W0160AGN    Partition Map Scheme : Master Boot Record
    Why is the status "not supported"?  How should I go about mounting the data volume so I can access the files on my Mac?

  • OracleVM and paravirtualized guest - "Boot loader didn't return any data!"

    Hi folks,
    we're having a problem here: We have installed the latest version of Oracle VM Server on a machine that does not provide hardware virtualization support (i.e., no Intel VT or similar). As a result, we will not be able to make use of hardware virtualized VMs, but according to the Oracle docs, we should be able to set up virtual machines of the paravirtualized domain type. So far, so good.
    Also according to the docs, when setting up a PVM, one cannot use an ISO image located in a storage repository in order to start the installation, but instead one would have the mount the installation ISO somewhere, make available it's contents via NFS (or HTTP / FTP), and then set up the newly created virtual machine to attempt a PXE boot, specifying the location where the contents of the ISO have been placed (i.e.: nfs:host:/path/to/mounted/iso). All of this is decribed very well in the Oracle VM Server docs (chapter 8), but somehow it still doesn't seem to work for us.
    What happens is this: When we attempt to boot our PVM via PXE, specifying the NFS location where we've made the contents of the ISO available, we always get this:

    Any ideas what we might be doing wrong?
    Greetings,
    Nils

    Hi Avi,
    thanks for your reply! Actually, I believe I checked the NFS reachability already. Here's what I can do on the VM server:
    [root@ORAVM1 ~]# ls /mnt/test
    [root@ORAVM1 ~]# mount.nfs 10.0.0.220:/mnt/iso /mnt/test
    [root@ORAVM1 ~]# ls /mnt/test
    EFI eula.py images media.repo README-en.html RELEASE-NOTES-x86_64-en RELEASE-NOTES-x86-en.html RPM-GPG-KEY Server
    EULA GPL isolinux Packages RELEASE-NOTES-en RELEASE-NOTES-x86_64-en.html repodata RPM-GPG-KEY-oracle supportinfo
    eula.en_US HighAvailability LoadBalancer README-en RELEASE-NOTES-en.html RELEASE-NOTES-x86-en ResilientStorage ScalableFileSystem TRANS.TBL
    [root@ORAVM1 ~]#
    So, I seem to be able to mount the NFS export correctly (what we're seeing are the contents of an Oracle Enterprise Linux ISO). And when setting up the VM, I specify "nfs:10.0.0.220:/mnt/iso" as the PXE boot path. Still it doesn't seem to work. :-(
    ovs-agent.log doesn't seem to contain too many additinal information of value either. Here's a snippet of what seems to happen when I power up my VM, but I guess there's nothing really new in there:
