General :: Grub All Over Display While Booting With USB
Jan 7, 2010
I am trying to boot linux kernel from a USB stick. I performed following steps:
1. wrote Grub stag1 to MBR of USB with this command on my linux host.
dd if=/boot/grub/stage1 of=/dev/sdb1 bs=512 count=1
2. Mounted the USB and I copied the following files in my USB.
boot/grub/stage1
boot/grub/stage2
3. Plugged in the USB in the the target machine. Rebooted and changed the booting sequence to boot from USB
My problem is that instead of getting a boot prompt, iIam getting GRUB GRUB GRUB all over the display. I googled out for it and found that if we change the auto-detection oh HDD in bios to manual that may solve the issue, but that did not help. If you happen to know that I am following the correct steps and in right order please point me how can I resolve this issue of GRUB.

I recently install Ubuntu-studio Desktop and some other packages. And, I upgraded my System. But since then, the Grub has started to display (I have only 9.10 installed, using the entire Disk). Also, unless I select the entry, Grub does not automatically start. The startup takes nearly 1.5 minutes. And, the Login screen, after the installation of Ubuntu Studio GDM, is much slower. I removed the Ubuntu-studio GDM package, still it takes about 20 seconds to allow me to enter Username and password. Any idea?

I'm writing this post from the BT5 Live CD. However, after install and reaching a CLI (on the HDD), when I run startx, my monitor simply displays 'invalid format' (obviously this works fine via the LiveCD)... I've installed Ubuntu and Fedora a few times on a few machines, and have never had any issues with the display... not sure where to start troubleshooting.

I need to show a static image with the logo of our department while Debian boots. Is there any easy way or tool to do this? (Any parameter of the kernel maybe?) It doesn't have to be anything fancy (like a progress bar)... just a plain an simple image.
I've seen many bootsplash projects..but most of them are broken. I tried splashy (which is available on the repo), but by the time it loads, my system is already booted, so I don't really like it. note that I don't have any Xorg server installed.

I work in a very restrictive environment and I want to use linux on my work laptop (currently running Windows XP prof). I am planning to install linux in a dual boot mode but I dont want to install grub/lilo or any other boot loader. i cannot even modify Windows bootloader to boot into linux partition.
Is there a way I can boot into linux partition without installing new boot loader or modifying the current windows boot loader? Any boot CD etc available that can boot into linux partition from my laptops HDD?

I'm triple booting (windows, ubuntu and osx86) at the moment but in order to load OSX86, I need to pass "cpus=1" to the kernel otherwise it won't load and the PC just reboots. Can I pass this argument from grub or do I have to install osx to a separate hdd and get grub to load the Darwin bootloader on the second hdd and then pass the argument?

I am having issues booting my LFS system on my hp nc8230 notebook running LFS SVN. Grub was built and installed per the book. My file system is almost as simple as it gets:
/dev/sda1 is swap
/dev/sda2 is my LFS partition /
The LFS live cd still uses the now deprecated drivers for HDD's thus as far as the livecd is concerned my block devices is (hd0) and /dev/hda2 for the root respectively. However the kernel to be booted runs on the newer drivers thus on boot my block device should be referenced as /dev/sda2 for the root. Grub is in fact installed on the MBR what happens is right when my system boots I get a file not found error the grub CFG is pointing to the correct block device and root partition from what can be seen by looking at the grub.

I am a bit confused about a dual booting system. I Already have windows 7 on my computer and wish to install ubuntu 11.04 but I keep reading about Grub 2. Does grub automatically install with ubuntu or do I need to install it prior to installing ubutu ?

I have just updated my Ubuntu linux to Ubuntu 10.4, not my grub menu isnt letting me boot to Windows Partition.The problem seems to be with grubs new update from using an editable menu.lst file to using a non editable grub.cfg file. Everywhere I look it states "DO NOT EDIT THE GRUB.CGF FILE". I am at a loss as what to do. I figured that the new configuration has screwed up the Windows Boot File. Anyone have any suggestions on how to fix this. I am not sure if it is a windows issue or an issue with the Grub boot menu.

I run alot of Linux running in memory. Mainly by PXE booting a kernel and the entire OS as the "initrd" file.
I have a RHEL6 image running as a VirtualBox guest and the entire OS (minimal) is contained withing 1GB of disk. I wan't to boot the entire /dev/sda1 "/" (its the only partition on the drive, no swap) as the initrd file and run everything from memory. But grub won't let me. So before I try and re-invent the wheel I thought to post here first.
Details. RHEL 6 as guest in VIrtual BOX. configured with 3Gb memory. HD is single partition and known as /dev/sda1.
at the grub console. I issue
root (hd0,0)
kernel /boot/vmlinuz-2.6.32-19.el6.x86_64 root=/dev/ram0
initrd (hd0,0)
But the grub windows just freezes. Apparently it doesn't like the fact that I've referenced the entire partition (hd0,0) as the initrd. Any thoughts? Or any better boot loader like SYSLINUX?
BTW, I am not worried about the /etc/fstab mentioning /dev/sda1 at this point, I have a fix for that already. I would like to see grub load up the partition as an initrd.

is it ever possible to do dual booting with grub(legacy) ever at all!. it is possible provided i take some pain, here is the link of that post [URL] i was coward and weak i didn't try that out then. but i did try it out. now so if u haven't seen the post .... I've installed Fedora 15 desktop(Gnome) with physical Logical volume called vg_fedora lv_root(ext4) ,lv_swap and lv_home(ext4), with 500MB /boot partition and had about 200GB free hard disk space ... so i wanted to install Scientific Linux 6.1 (because our school uses RHEL 6.1)
so, while running the installer I made (added) a logical volume lv_Scientific with ext4 FS and made its mount point (/) and used the MBR /boot which overwrote the Fedora /boot (completely OK and was as expected) i restarted after installation i got SL log in and as per the directions of the thread i copied the boot stanza from grub.conf of fedora 15 (which i already had copied and pasted into a text file and copied it from there)and pasted it into grub.conf of SL you may ask why did i choose same physical LVM too save swap space ... if i had made another physical LVM i had to make another swap ( i like LVM ... its cool)
completely unexpected happened Fedora now boots but not SL when grub starts i get this error 27 unrecognised commad and when i press <enter> i get grub menu with SL and fedora when i press on Fedora it works well i get my fedora login and i did login .. everything works fine but when i press SL it goes to the previous black screen grub error 27

I was unaware of the difficulties of installing and booting Ubuntu from the "onboard raid" that the NVIDIA nForce chipsets provide. However, I've managed to get it working reliably with one single caveat:
When update-grub builds the grub.cfg, it refers to all of my partitions as follows:
Code:
menuentry 'Ubuntu, with Linux 2.6.35-27-generic' --class ubuntu --class gnu-linux --class gnu --class os {
recordfail
insmod part_msdos
insmod ext2
set root='(/dev/mapper/nvidia_caifaefg,msdos5)'
[Code]...
So I'm guessing that the whole nvidia_blah,msdos5 is because of that. However, it doesn't seem to explain why Grub would THINK that would work and it in fact does not work. That's the biggest source of confusion on my part.
My questions are as follows: First off, because as an IT person I want to know: Why does this sort of change work? What does changing that device name change in GRUB's behavior? Is there a setting in /etc/default/grub that would change the way it's naming these RAID devices? Is there a value for this setting that would give me the device names that work, as explained above?
If there is no setting change I can make in /etc/default/grub, could I add a sed command on to the end of update-grub or can I make a modification to one of the scripts in /etc/grub.d? What sort of change would be recommended? How would I preserve this change through later package upgrades that would possibly rewrite these files?

booting up the PC (Before or After user login) display an "Acceptable Usage agreement" with a OK button. The User must press OK to proceed. The Acceptable Usage agreement shows our companies System network policy. It can be easily done in a windows PC (Look Here). But I don't know how it is configure in ubuntu .

I downloaded Ubuntu 10.04 Desktop and have tried booting the ISO from a USB stick and also installing it to my HD with Wubi.Unfortunately my experience hasn't been any better than when I tried Ubuntu 8.10When booting the Live iso from my USB stick, my display goes into sleep mode (IE is receiving no signal) from the momentUbuntu begins booting until eventually the desktop appears several minutes later. If I was the average punter I would probably have assumed nothing was happening and rebooted.
As I have some experience with Linux (barely), I thought to try Ctrl-Alt-F1, which brought the monitor back to life and showed the terminal. As soon as I switched back to the main window (Ctrl-Alt-F8 I think) the display went back into sleep mode.Once it had booted, I did "sudo apt-get update", which worked and then "sudo apt-get upgrade", which did a lot of updates and then sent my monitor back into sleep mode, requiring me to reboot!When I tried to boot the Wubi install, again the display went into sleep mode as soon as Ubuntu started booting but this time the desktop never appeared and after about 5 minutes I rebooted.My motherboard is a Gigabyte MA780G-UD3H and I'm using the onboard HD3200 IGP and a Phenom II X3 720 and 4GB DDR2 1066Mhz RAM.

I am testing my crash recovery strategy for my linux system and I am having trouble with GRUB. I am basically restoring my backup (i.e. tar) unto a different hard drive, but I am having problems getting the machine to boot without me having to type the GRUB commands at the GRUB prompt that is presented when the machine boots up off the new hard drive. I have tried to restore the MBR in two ways (the 2nd one is the one that gets me to the GRUB prompt):
1. Get the MBR off the original drive and write it unto the new drive (all via dd), but that did not work at all: the machine hangs right away during boot up. It seems to hang right at the point where the BIOS tries to read the MBR.
Code:
On original drive:
# dd if=/dev/sda of=mbr+part.bin bs=512 count=1
On new drive (new drive is now in place of original drive):
# dd if=mbr+part.bin of=/dev/sda bs=1 count=446 conv=notrunc
2. By using the FEDORA rescue CD, I installed grub unto the new hard drive as follows:
Code:
# chroot /mnt/sysimage
# grub-install --root-directory=/boot hd0
reboot and remove FEDORA CD Using the 2nd option above, I get the GRUB> prompt during bootup. I can then boot into the system by issuing the commands that are in the menu.lst file, followed by the "boot" command. However, I would like for those commands to happen automatically, just like in the original configuration. It seems to me that GRUB is actually finding all its stage files because I doubt the GRUB program (the one displaying the prompt) fits entirely in the 446 bytes it has on the MBR. So, it must be loading its stage 2 (and stage 1.5??) files from my /boot partition. However, if GRUB is loading its stage files off the boot partition, why does it not load/read the menu.lst/grub.conf contained in the boot partition also?
Code:
# ls -l /boot
total 22888
-rw-r--r--. 1 root root 1274567 2009-05-27 16:39 System.map-2.6.29.4-167.fc11.i686.PAE
-rw-r--r-- 1 root root 1274538 2009-06-16 22:27 System.map-2.6.29.5-191.fc11.i686.PAE

I have a working server running CentOS 5.5 (similar to RedHat EL) with the 2.6.18-194.el5 kernel. The hardware is a few years old, but we were able to accomplish this following goal using CentOS 4.4. What I'm trying to do is to back the system up to an external USB hard drive such that it can be booted from for recovery or to then take that drive and restore its contents to a second server with identical hardware. We have been successful implementing this on other server pairs, but I'm having a great deal of trouble getting this to work on this hardware and OS. I'm not using LVM or dual-booting with another OS. The USB drive is set up with identical partitions to the RAID set, and all the files have been successfully copied over, but I can't get the system to boot from it. Below is what I get when trying to boot from the USB drive:
Code:
Booting 'CentOS (2.6.18-194.el5)'
root (hd0,0)
Filesystem type is ext2fs, partition type 0x83
kernel /vmlinuz-2.6.18-194.el5 ro root=LABEL=/

I have tried and failed to install F14 and 15 on my system for a while now and I have been running Ubuntu in the mean time as it installs and runs fine as does Mint, and Suze.
My Pc is getting a little old now but is still very capable, however the Primary master Sata port seems to have a fault on it so I don't use that anymore as it ends up corrupting my hard drive after a few weeks.
I am running one hard disk on the secondary sata port which shows up as the primary slave in Bios.
When I install F14 or 15 all goes well till I restart then it boots to Grub with no errors.
I have tried assigning root in grub and it doesn't seem to think any hard disk exists from what I have tried, what am I missing?
Just to confirm I am running one hard disk on the second SATA port, Fedora detected it on install as sda1, and the rest of the linux partition as sda2.
I have tried this multiple times and the grub was installed to the MBR
