Hardware :: GRUB Installation In Embedded Device?
Dec 10, 2010
I want to make a bootable USB drive with a Embedded Linux Image. The Embedded Linux Configuration tool has given me the vmlinux(image) and the menu.lst. I have done the following Steps; # fdisk /dev/sdb Then I got some option I deleted the old partition and made new one and selected the primary partition. then formatted the partition in ext2.
# mkfs.ext2 /dev/sdb1
# mount /dev/sdb1 /mnt
# mkdir -p /mnt/boot/grub
# cp menu.lst /mnt/boot
# cp vmlinux /mnt/boot
# umount /mnt

I am to drop Linux onto an ARM9 NAS board to make it more useful than just a network attached storage device.
I know about U-Boot and I can install Debian Linux by booting the system via TFTP, and I can install Linux easily... if I have an internet connection.
My question is, how can I install Debian WITHOUT the use of an internet connection. I am looking into downloading the armel flavour of Debain and using that as a source, but I have no idea on how to install it onto an embedded system as it has no CD/DVD drive. It only has an ethernet port, 2 USB-2.0 ports and a serial UART port.

I updated yesterday and now when I start my laptop it goes in to grub rescue mode. I have booted from a 'live cd' and thought I could repair grub from there. In gparted however the partition with ubuntu (sda1) is seen as unknown file system, in terminal when I list the partition table it shows up as FAT16 type. When I try a grub-install it gives this error message:

I am developing a device that will run Linux as its operating system.The device is a small form factor X86 device with a flash drive exposed as a SATA-device. So it is not very dissimilar from any other PC running Linux.For several good reasons I am building my own "distribution", instead of using an existing one.What confuses me is how mount/umount of the root file system is handled.I boot my kernel with the commandline "root=/dev/sda1 rw" which works fine. But everytime I do poweroff or reboot Busybox complained about no /etc/fstab, so I decided to build one.Should I have an entry for my root file system? It seems like this is shadowed by the rootfs anyway. I.e. if I have the fstab entry "/dev/sda1 / ext2 1 1" mount still reports rootfs on / type rootfs (rw)/dev/root on / type ext2 (rw,relatime,errors=continue)My questions are:Do I need to worry? Will the drive be correctly unmounted by the kernel on poweroff/reboot?If I want to perform file system checking on boot, can I do that without resorting to an initrd?

I'm trying to get sound to work on an embedded board. The boot says ALSA is present and sound chip is present. So I try to open the device with:
The hardware manufacturer assures me the device is hw:0,0 so I set device to:
This gives me:
So I'm presuming the advice that I use hw:0,0 must be wrong? So I need to find a way of working out what the device id is. I've tried default, no effect, then tried the command asoundconf list, which returns an error. I'm using a min linux build on an embedded system (busybox) so is there a way to find my sound device.

I'm working on a project to have our company logo image display on the screen during bootup. Our platform is an embedded Linux device running on a custom configured linux kernel 2.6.38.2. Our development distro is Ubuntu 10.04. I am currently trying to get fbsplash to work on our device with no luck so far.

I just (for the first time ever) installed a version of Ubuntu. It is 10.04. I installed off of the Live Disk. I was having a great time until the first time I went to boot into it and I got the message
"Error: No such device: "long number" Grub Rescue> "

I'm attempting to install Debian to an NVMe SSD (Samsung 950 Pro), however both Jessie and Stretch images fail to install grub.
Checking the syslog reveals the following error:
grub-probe: error: failed to get canonical path of /dev/nvme0n1p5
Further Information:
Fast-boot is disabled in the UEFI, and boot mode is set to UEFI only, no CSM. I do not see any option for 'Secure Boot' if it's relevant to the issue.Windows 10 has already been installed, which created several partitions. The ESP/EFI partition appears to be on nvme0n1p2I only created one partition for Debian - / on nvme0n1p5, no separate partitions for /boot, /home etc.

I'm using Kubuntu 9.10 with Ubuntu-desktop installed.I've been using kubuntu for sometime now but i dont know much technical things about it. I have two hard discs (160GB SATA and 80GB PATA).I have just installed Windows XP Professional and then reinstalled grub2 from a live CD. Both OS are on 80GB PATA drive.The Grub menu at boot time has "Windows XP Professional" entry in it. The problem is thatwhen i select that entry, i get an error saying:Quote:Grub:Error:No such device - "a string of letters and numbers"Press any key to continue...When i press any key, it goes back to the grub menu. Kubuntu and Ubuntu work fine.When i go to bios and change my hard disc boot order, grub is bypassed and Windows boots and works good. I dont know much technical things but i think maybe its the problem with Windows entry in grub. (something to do with lines map(hd0,hd1) and map(hd1,hd0) (But i'm nt sure. I just said wat i thought it might be)

Here is a brief history of my problem:
-Ran Windows XP Media Center for most of the life of this HP Pavilion notebook with 2 hard drives, C: and D:, no partitions except the default HP recovery partition
-Yesterday, installed Ubuntu 9.10 through Wubi on D: from an ISO (because the CD drive doesn't work). I assigned it 30gb on D:, which I assume created a 30gb FAT32 partition on this secondary drive.
-Dual booted successfully from Grub between XP and Ubuntu, so I thought, "Mission accomplished" and started making friends with GNOME. Got a pretty good score in Tetris.
-Was asked if I would like to update to the latest Ubuntu (10.04 I think?) which struck me as a good idea. Everything went smoothly until it asked me to reboot.
-Reboot brought me to a command-line that says "grub rescue>" and above it says "error: no such device: e76e00f3-........" (there's more, I can write it out if that helps)
-Rebooted several more times (cause that usually fixes things) but just got back to "error: no such device: ..." and "grub rescue>"
And that's where I am now. I have almost no experience with how Linux (UNIX?) works differently than Windows or how to use the command line. I know that the hard drives are (hd0), (hd1) instead of C: and D: and that everything important seems to start with "sudo" and that's about it. I was going to ease myself into the whole thing gradually, picking up little bits as I go along. But now I'm just stuck in command line limbo and none of my usual troubleshooting strategies apply here, not even yelling rude things about the computer's manufacturer.

yesterday i upgraded Ubuntu 10.04 to 10.10. During installation i also upgraded grub to version 2. It said that there were two options that i could choose to boot and i choose both. Installation finished with out a hitch. When i attempted restart my laptop i got this message:
error: no such device: 12631218-8ac6-4505-b4cb-a66a1de1814f
grub rescue>
I tried the command help and received a message saying that the help command was not recognized. So i then gave Google a bit of a work out and have tried reinstalling grub and manually coping the grub files all to no avail. The problem i believe stems from how i have Ubuntu installed. I have Ubuntu installed like an application on windows 7 on a separate partition on my hard drive. Looking back on it i'm not to sure why i choose that route, but that is how it is installed.

I just installed Ubuntu on a separate hard drive alongside Vista, and after restarting, my computer booted to a screen that said, "error: no such device: xxxxx-xxxx-xxxxx-xxxx (I don't remember exact number, if I need them I'll go back and write em down) grub rescue>"
After a bit of searching I found this thread: [URL].. I tried the first part twice which didn't change anything, so I tried the last part which was too fix the vista bootloader, which worked perfectly, and now I can get into at least one operating system. Would anyone please help me get a bootloader working so I can choose between Ubuntu and Vista? Also, is it worth mentioning that right before the computer shut down after installation, I had a huge list of I/O errors?
EDIT: After further searching I read that the I/O errors were commonly because of a faulty cd or it was spinning too fast. I think my problem with that was that it was spinning too fast, it was incredible loud and there was a huge amount of wind coming out of my computer XD. iirc I have to go to the BIOS to change disc speed?
EDIT2: I think all my problems stem from a faulty CD. I remember setting the burning speed too the highest setting when I burnt the live CD, I guess I thought faster was better.

I have a raid 0 setup with 2 x 1TB drives. I have an ASUS P8P67 LE motherboard and am using Interl RST for the Raid setup. I'm utterly ignorant of raid and therefore forgive any mistakes... I already had windows 7 installed and was attempting to dual boot ubuntu.
I installed Ubuntu from CD. The raid was picked up properly as only one drive by ubuntu. So it picked up the windows MBR and the main windows partition. I resized the main partition and used the "install ubuntu and windows 7 side by side" option. Installation went fine but once I restarted the PC I was welcomed by a grub rescue screen with the message: "error: no such device e196.....". Edit: I used the Windows 7 disc to repair the windows bootloader so I can now boot into Windows 7.
Before doing so I used gparted on the live cd to check the partitions on the drives. The only ones present were the MBR and windows one. So ubuntu seemingly didn't install... Although GRUB did... I was advised by someone on the ubuntu IRC chat to avoid trying to reinstall ubuntu at that point just in case there was an error in the partitioning process. I've since checked the state of the partitions from within windows and there's the MBR partiton, the windows partiton AND the partition that I created for ubuntu... 965MB of the partition that I created is listed as used space as well...

I'm inexperienced in Debian. I have a dual-boot machine (64-bit, Debian 7.3, Windows 7, legacy boot) and encouter a problem at boot ever since I completed the installation of Debian 7.3 alongside the exising Windows 7. This machine has six hard drives: two are intended for ntfs storage of general data (raided together by RAID1); two more are intended for ext4 storage of general data (also raided together by RAID1); the fifth contains the Windows OS files and the sixth contains the Debian OS files. The problem is that I arrive to the grub_rescue each time at boot, seeing the message:
GRUB loading.
Welcome to GRUB!
error: no such device: e081517b-3399-4067-9294-8f0686f753ca.

I am having trouble getting a dual boot setup on Ubuntu remix on a netbook. The install went fine, but then windows would not book. I had a windows error. So I reinstalled windows, and rebuilt grub. Now when I try to launch windows from the grub menu it says "error: no such device: 0a82ff1982ff0849". How do I go about fixing that? I can boot to Ubuntu fine now.

The problem after couple installations (10.10 --> 10.04 --> 10.10 --> 10.04-3) is that system goes to "busybox" after complaining about missing root device. I already have come to conclusion that this problem could be solved by telling the system that the root device is at sda1. However, I'm not able to start grub (by pressing "ESC") at boot before problems start. I'm able to start live-cd and I tried to install "over" the old one (same partitions without format, same username). No luck.
And in the busybox /proc/modules is empty for example. And the grub has worked with previous installations.

I have two partitions on my HDD. A Windows XP (hd0,2) and an Ubuntu 9.10 (hd0,1).I have been using the Windows mainly and ran a program that changes the HDD's serial number. Now when I boot up and Grub loads, I try to access the Windows partition and get the following error:
Error: No Such Device: 2e3857fb3857c08f
I am still able to boot the Ubuntu partition but can not seem to get grub to point to the Windows partition any more. This is very frustrating as I really need to get back into that partition soon.

I already had windows 7 installed on my raid. So I figured that I would install Ubuntu on my 250gb external. I burn it, boot to CD, and tell it to wipe and install the external hdd. After installation it prompts me to take out the CD, then press enter for it to restart. It restarts, gets all the way through and then says:
Error: no such device: f8b79a59-3c13-408a-b332-dd5e9dc37729. Grub rescue>
I am unfamiliar with this issue, and would have looked for a fix on my windows side, but now I am unable to boot into my windows side at all.

I had a working dual boot Ubuntu 10 and Windows 7. Anyways long story short, I got it working again but have lost the boot option for windows 7. If i run fdisk -l, I get the following.
root@support-Latitude-E6400:/home/support# fdisk -l
Disk /dev/sda: 250.1 GB, 250059350016 bytes
255 heads, 63 sectors/track, 30401 cylinders
[code]....
I installed gparted and can see that windows 7 is installed in dev/sda6. In another forum, i read that someone had to edit their menu.lst so i did with the following.
title=Windows 7
rootnoverify (hd0,6)
makeactive
chainloader +1
When i try to boot from windows 7, i get the following error. Error 12: invalid device request. How can i get my laptop to boot from windows again?

i am working with an old system that uses a BIOS meant for embedded systems. According to my coworkers this thing boot some version of debian about two years ago. currently I have used there old image and a new one I made of the latest Debian stable build. both images fail to get passed grub.
to be clear the BIOS simply replies "loading grub" takes ten minutes and then crashes.
has anyone ever had trouble with grub crashing systems? this problem seems odd since is did boot with this two years ago and i still have that image.

I'm currently setting up a dell server with hardware raid 1 on sas 6r. i got 4 sas installed on the server and configured to raid 1 as stated below,
array 1:
slot 0 & 1
array 2:
slot 2 & 3
during the installation, the installer detect the array 2 as sda and array 1 as sdb.. so i proceed with installation on array 2. after completed the installation, the first reboot lead me to a 'grub-rescue" prompt. by following the guide at url Mode, i've noticed that the boot folder has changed to (hd1,1), which i believe it has changed to sdb1. default root device shows that prefix=(hd0,1)/grub.

I was dual-booting Ubuntu 11.04 just fine for about the last week but then ran into some issues and decided to reinstall Ubuntu. Now after the install I get this error: error: nu such device: d38af2a9-740e-4d3c-b267-2a3848e5d319 and it goes into the grub rescue command prompt screen. I have tried to reinstall Ubuntu about 6 times now, complete installs. I have tried changing boot priority multiple times. I installed off a thumb drive and left the thumb drive in after install, took it out after install.

I am running a Windows 7/Karmic Koala Dualie. I was running Windows 7 first, Shrank Windows, partitioned the drive using the 40 free unallocated gigs of the 300 gig hard drive, and installed a fresh install of Karmic Koala to that. This has been working just fine (minus a few graphic driver issues) for the last week or so. Then wanting all my content to be available to both system and my network easily I decided to shrink the Windows 7 side, and use the 90 now free gigs to create a FAT32 Partition (using Partition Wizard after I had defragged the disk) The process runs fine, I boot back into Ubuntu where I have made my Windows 7 drive NTFS partition mount automatically, and I pull my videos and music to the new partition. At this point everything is going great till I fill the partition, and I decide to boot back into Windows to decide if I need to shrink windows to make the new partition any bigger. Well this time I go to GRUB hit windows and I get: Error: No Such Device: 01caab4e3c9fb9e0
