Ubuntu Installation :: Grub-probe Mapping Error In GRUB2
Jan 6, 2010
I am having trouble upgrading from old grub to grub-pc. I have a clean install of 9.10 on a system with a new ASUS motherboard with Nvidia RAID configured as RAID 0.Although I read the page on SATA pseudo-RAID, this doesn't seem to apply, as both 9.10 and Windows XP installed cleanly without any additional drivers required.I did notice that contrary to the documentation, 9.10 installed with grub v0.97, not the new one as claimed. It is working fine, but just to be ornery, I'm trying to upgrade to the new one, and this is where I ran into trouble.Whenever I try to run grub-upgrade, I get an error from grub-probe that 'no mapping exists for' my raid partition. Apparently grub-probe can deal with the device, but not with the fs_uuid, as follows:
twescott@latitude:~$ sudo grub-probe -t device /boot/grub
/dev/mapper/nvidia_fcacbeib5
twescott@latitude:~$ sudo grub-probe -t fs_uuid /boot/grub
grub-probe: error: no mapping exists for `nvidia_fcacbeib5'
The system seems to be recognizing the RAID with no problems, as in:
twescott@latitude:~$ sudo blkid
/dev/mapper/nvidia_fcacbeib1: UUID="28D83EB2D83E7DDE" TYPE="ntfs"
/dev/mapper/nvidia_fcacbeib2: UUID="4344165e-07c3-4da6-b640-da9bf964a74e" TYPE="swap"
/dev/sda: TYPE="nvidia_raid_member"
[code]....
I'm thinking the problem may be in my grub device.map file, which only lists the SATA raw device aliases, but I may be completely wrong:
twescott@latitude:~$ cat /boot/grub/device.map
(hd0) /dev/sda
(hd1) /dev/sdb

I have a clean install of mythbuntu 10.10 and I am trying to get a DVB-T USB stick working for the last 2 weeks. Its a MobiDTV and it seems to have the same chipset/USB ID as EzCap_DVB_T_Stick. I followed the instructions on the [URL] and eventually got the driver compiled (I had to amend some code, change "Bool" pointers to "bool" and add a FIRMWARE MAX_NAME 30 constant). I also copied the af9035 FW file to the firmware directory.
lsusb:
Bus 002 Device 004: ID 15a4:1001 Afatech Technologies, Inc. AF9015/AF9035 DVB-T stick
but it is not working; probe is failing:
dmesg:
[ 105.104195] DRIVER_RELEASE_VERSION : v2.0-1
[ 105.104203] FW_RELEASE_VERSION : v8_8_52_0

[ 105.110713] [Device_init] Error 1
[ 105.110733] dvb_usb_af903x: probe of 2-5:1.1 failed with error 9
I bought the hardware with Windows 7 MCE in mind. I have no Windows 7 disk so I installed Mythbuntu on it to see if build was solid and now I don't want Windows any more.

I have a Debian Lenny box with two hard drives in it (no dual boot; /home and /var are on the second drive). This machine was working fine until earlier this week when I ran an upgrade and restarted it. I think during this upgrade Grub got upgraded to Grub2, and now when I try to reboot I just get this:
Code:
GRUB Read Error
Hitting Enter yields Operating System Not found. This is it, I can't get into the grub screen to enter the boot command or anything. I booted the machine into the rescue environment on the Install CD, and was able to mount all the file systems and chroot in. I tried reinstalling grub2, but this did not help. I ran fsck on my /boot file system, but it appears fine. The boot partition is also marked with a bootable flag in fdisk. I did try to downgrade back to grub1.5 which, while it didn't given an error did hang shortly after it loaded.

I have an old computer that I use for trying out software and other things before putting them on my newer machine so as to avoid irreparable damage. The machine has 2 hard discs; the first disc contains Windows and I wanted to use the second disc for Linux. I installed Fedora 14 on the second disc and followed this with Ubuntu 10.10.
After I installed Fedora I re-booted and had a choice between booting into Windows or Fedora. After adding Ubuntu I assumed that Grub2 would pick up both Windows and Fedora and add them to the grub menu but instead, the grub menu only contained the options to boot Fedora or Ubuntu. I tried running 'sudo update-grub' but got the following message:
"cannot access /var/lib/os-prober/mount/boot
Boot: No such file or directory"
When I had a look in /os-prober all that was there was a file called 'labels' and when I opened it it consisted of the one line "Fedora 1" It looks to me, who doesn't know a lot about grub2, that something is missing from grub and had wondered whether to re-install it or whether doing so would be jumping out of the frying pan into the fire.

I just installed Fedora 11 on an AMD CPU PC. I get the following error during boot up.Aug 22 21:42:07 dragon8 kernel: aic7xxx: probe of 0000:00:0a.0 failed with error -38 Because the aic7xxx has the error, it does not load the st module. I manually loaded the st module, but the /dev/st? devices do not get created, I assume because of the aix7xxx error.I can access the Adaptec AHA-2940W Bios during boot up and see the 2 tape drives that are connected to it.

I'm looking through dmesg and see
Code:
nvidia: probe of 0000:00:03.5 failed with error -1
the corresponding bus is
Code:

from where I infer that the module is correctly loaded though. Do you guys know what is the -1 error code? is there any way I could check if the coprocessor is currently working?

I am trying to use a rig with Gigabyte GA-880GA-UD3H mother board and Intel 82574L based NIC (EXPI9301CTBLK) under CentOS 5.5. Unfortunately I have issue with the NIC - during boot it fails to initialize:

I receive the same result with the original e1000e driver from the distribution, the latest elrepo driver and the latest driver from Intel site (as seen in the example). I have tried also 2.6.37 kernel version - with the same result. The adapter however works fine under Windows (MiniXP from Hiren's BootCD) and with Ubuntu 10.10 LiveCD.

So I have an MBR that is Grub legacy,(from HardyHeron) and I cannot edit/upgrade this MBR. (I won't get into the reasons, other than I will mention SafeBoot).
I have a new encrypted LucidLynx Linux installation on partition 4 and an unencrypted /boot partition on partition #3.
When I boot up, I get the "Error 15" Grub error, which is expected as Grub legacy is looking for /boot/grub/stage2 or something like that and /boot/grub/stage2 does not exist in my GRUB2 installation in /boot/grub.
I thought if I could make a link from the GRUB2 binary of interest to /boot/grub/stage2, then maybe the GRUB legacy would be tricked into loading the GRUB2 binary.
what is the binary of interest in the GRUB2 installation that is the main binary?

I have been running a dual boot XP and Ubuntu 8.04 on two separate hard drives for a while now without any problems. I used the method posted http://ubuntuforums.org/showthread.p...light=dualboot. I will be upgrading to 10.4 soon (probably after the re-spin in July) and was wondering if I will have problems after upgrading dual booting.
I do not know if while upgrading Grub remains or if Grub2 tries to overwrite. I have read that Grub2 will try to install onto all partitions and hard drives in a fresh install but do not know about upgrading. If it does try I think I need to put it in hda,1 which is the primary drive where Ubuntu is located.
This is not something I have been able to find the answer to with google. I also have Kubuntu on the system which I can change with session manager and am not sure what will happen to that once I upgrade Ubuntu.

I have a dual boot system with ubuntu 9.10 x64 and Windows 7. Everything has been working fine for a a long time but yesterday I tried to delete an unused partition through the Disk Utility in ubuntu (System->Adminstration->Disk Utility) and everything was messed up. I used to get the "Grub error: Unknown filesystem". I managed to create an ubuntu bootable usb and followed some tutorials for fixing grub but all i managed to do is to get another error: "Grub error: No such disc". After some experimentation i got
"Grub stage 1.5" which gave me a grub> command prompt./dev/sda is the drive containing Windows and Ubuntu.

I mucked things up a bit--
1) I had only windows on my drive.
2) Using 10.04 on USB, I made a 10gb ext3 partition and a 1gb swap area and installed 10.04. No problems at all using grub2, and the GUI is nice for dummies like me.
3) I got antsy so I made an 8gb partition and installed 8.04 on it. It automatically installed grub (the old grub).
Now when I boot my machine the Old Grub loads, not Grub2. I can select 8.04, 10.04, or XP no problem. When I select 10.04 and use the GUI I can see 10.04, 8.04, and XP, but things are in a different order (clearly the grub2 order).
Questions:
1) How can I get grub2 to take over booting? (I like the GUI)
2) I'd like to install puppy linux too, but I'm afraid of really screwing things up. Can someone recommend a safe way of installing it (besides just running from a USB- I've had mixed luck using USB OS's over long timeframes).

I moved from 8.04.2 to 10.04.2 and tried to upgrade from GRUB Legacy to Grub2. I must have made a mis-step somewhere in the process as on boot it now tells me
Code:
GRUB Loading stage1.5.
GRUB Loading,
Error 15
_
Is there a nuke from orbit, no finesse way of just ripping all the existing GRUB mess out and installing GRUB2 from Boot disk? for instance should I be just be able to boot with a LIVE CD mount the primary disk of this machine and enter the below in a terminal without messing up any further?
Code:
sudo grub-install --root-directory=/media/PRIMARY_DISK /dev/sda

I tend to update stuff slower than most - I'm still using Hardy and I probably won't upgrade to Lucid until June-ish. I wanted to test drive GRUB2 so I upgraded following instructions here:When I chainloaded GRUB2, I got a menu that only contained Ubuntu; my Windows Vista bootloader entry had disappeared. I couldn't find a sample "40_custom" entry to modify when I tried to create an entry for Vista myself. Had no problem booting into Ubuntu and I could still boot Vista from the old menu. Spent about 20 minutes on it, then I gave up and reinstalled legacy GRUB.

I just installed Ubuntu 10.4 beta. The installation is fine, but grub2 isn't loading Linux. Instead of booting into the OS, I get the message: No such disk grub rescue >I have two hard drives: /dev/sda and /dev/sdb. Ubuntu is the only OS and is located on /dev/sda1. I ran the "boot info" script and include the results here. One problem I see is that I have grub2 on the MDRs of both /dev/sda and /dev/sdb. BTW: From the Live CD, I can select boot into hard drive and Ubuntu will start up just fine. I can also use "Super Grub" CD and everything loads fine.

I have had it with the frustration of trying to figure out how to successfully install grub on my own, so I am hitting the forums. What can you tell me about installing grub/grub2 (whichever is best -- I want something that works) to my single hard drive computer. Operating systems: Windows XP, xUbuntu 9.10 Hard drive: Samsung SATA 2, 1 TB Desired result: Menu that loads upon boot so that I can select which OS I would like to load without inserting media device or disk.
I thought this individual had the most straight forward and thorough tutorial (of any I have seen) on the subject but precluded at least one thing for me that I cannot afford to ignore: I don't seem to have a "stage1" that can be loaded by the grub shell. Trying to find it in /boot/grub/stage1 in the grub shell, I get... "Error 15: File not found" What I do have in that directory is 'grubenv'. When I boot up, it loads grub, but it comes up with an error message saying, "File not found". Then, all I get is the 'grub rescue' prompt: "grub rescue>".
Obviously, after spending hours on this thing, this is not the whole story. But there have been so many attempts to try fix it with one thing or another, that I cannot easily relate them all, if I could even remember each one.

I've tried to be clever but as usual I didn't think before acting and missed a small detail.
I have recently installed karmic (dual booting with Vista) on my dell xps laptop. The install went fine, I'm very happy with my new OS.
I bought a new Seagate 500GB portable external HDD. I got a bit over-excited and installed karmic on the external drive. This worked fine and I got a lovely (but slow to appear) Grub2 menu showing my vista and both ubuntu options.
My problem is that now, when I unplug the external drive, Grub fails and I get a grub rescue> prompt. So I need the external drive to be plugged in if I want to boot.
It seems I have done something to the grub configuration. I have read around the subject but I am not confident about how best to proceed.
I understand there is an 'advanced' option in the installer which will allow me to choose where to install grub. Presumably I want it on the internal drive so that I can boot without the external one plugged in.
Am I right in thinking I can just pop in my install disk and redo the installation?
If I indicate I want to install Grub on the internal drive, which partition should I aim for?
Will I get a grub option for booting to the external drive?
Will I be able to plug the external drive into a different machine and boot from it?
I haven't done anything with the fresh install on the external drive so I don't mind losing that.

I have a dual boot config with
sda1 /boot
sda2 Win7
sda3 /
sda4 Truecrypt Partition
i have grub1 working and chaonloading truecrypt loader if i choose "win7" in grub1 menu I want to install a new kubuntu (no upgrade) I have read that that there are problems with grub2 and truecrypt actually a bug that grub2 dont chainloads truecrypt boot loader many ppl seem to have problems with grub2 then i read somewhere that ubuntu install is not asking for grub2 to be installed and just installing it. is this right?
i think at least for the alternative install cd its wrong. i installed it on another pc and it asked me! it works for win7 and Ubuntu and i guess its grub2 but there is no truecrypt installed anyway, i wanted to ask is the live cd installer asks me for grub2 and what is the best and easiest way to stay with my grub and just change the menu.lst to the new kernel (i guess there will be one)

I have a Dell machine with two hard drives that has Windows XP Home on the first disk (sda) and I just installed Karmic to the second hard disk (sdb) and when the install finished installing Grub2 to the MBR and the system restarted, I get the no such disk error and the grub rescue prompt. There is no option in BIOS to boot from the second disk. What do I need to do to get this working?

I've been using Ubuntu since 7.10 Gutsy Gibbon. I only recently fully switched to Linux OS's, and Ubuntu is now my primary. I currently have 9.10 installed. CURRENTLY I also have Backtrack 4, and Fedora 12 (Ugh!).Previously, I thought something was wrong with my my filesystem in Ubuntu 9.10, and after an upgrade of the linux kernel, I started to get Error: You need to load the Kernel First. That's where my problems started. I had upgraded to 9.10 from 9.04 and I still had Grub Legacy, so I went through hoops to try and get it to work, but eventually everything just kind of broke, and I completely wiped off my partitions on it and started fresh installs of all 3.
And now that the new linux kernel is released, 2.6.31-20 generic (I think... That's what the highest number on a file I can find in /boot is)I went through a few more hoops and ladders and tried to get it to work, but to no avail. I've looked the internet for a solution to this and tried just about everything but there is no unified answer, and I've seen on Launchpad there are alot of bugs that are classified as 'Fixed', but the problem still remains.I took out the 'quiet splash' part in the GRUB2 line for the newest kernel and it didn't do anything. It only changed it to "Error: Couldn't find file".This is the top two kernels (Main and Recovery for the new, and Main and Recovery for the previous working one)

Im running Ubuntu 10.10 32 bit and Grub2. When running the update manager, I get the following message while it is configuring grub-pc: The Grub boot loader was previously installed to a disk that is no longer present, or whose normally unique identifier has been changed for some reason. It is important to make sure that the installed Grub stays in sync with other components such as grub.cfg...I change my hardware, including hard disks, frequently so that is likely the cause. My computer still boots but I like to fix this if possible. My disk partitions are:/dev/sda1/boot/dev/sda2/ /dev/sda3/home

I have Lucid installed on a computer. I added a second drive, installed Windows 7. Windows 7 boots fine if it is the only drive connected, or it is selected as the boot drive in the BIOS. I booted into Lucid, ran 'sudo update-grub' and it found the Windows 7 install on the second disk. When I try to use that Grub entry to boot Windows 7, I get this error screen:
Code:
Windows Boot Manager Windows failed to start. A recent hardware or software change might be the cause. To fix the problem:
1. Insert your Windows installation disk and restart your computer.
2. Choose your language settings, and then click "Next."
3. Click "Repair your computer."
If you do not have this disk, contact your system administrator or computer manufacturer for assistance.
File: BootBCD
Status: 0xc0000225
Info: An error occurred while attempting to read the boot configuration data.
I seem to remember in the Grub 1.x days there was a map command that would 'swap' the drives so Windows would think it was the boot drive, but the Grub2 autogenerated command doesn't have anything like that.how to get Grub2 to boot Windows 7?

I have an old BIOS (only 149 GB detected in 160 GB drive). I have installed very few OS as a result - Windows in first 80 GB , 2 distros (20 GB each) in next 40 MB which is within the 149 GB. On issue of "update-grub" grub seems to detect all OS and generates grub.cfg. But on boot , one distro does not appear in the menu.

I have installed 11.2 with English as default language. During the installation, I tried to change the default keyboard mapping to Spanish, but right now, when the system boots it uses an English mapping. I've seen there is an option to change that on the grub menu and I would like it to default to Spanish. Is it possible? I haven't found much info on the web, but my guess is that changing the DEFAULT_APPEND in /etc/sysconfig/bootloader with an unknown-keyboard-related option will solve it.
