Ubuntu :: GRUB File Not Found - Change The Path Of The Grub Reader To Sda 5 ?
Aug 15, 2010
I gave sda1-2 for windows and sda 3-4-5 on an extended partition for my linux OS. I installed ubuntu on sda 7 (when I go into disk utilities it shows up as sda 7 idk why) alongside another ubuntu on sda 5 ( EXTENDEDPARTITION : sda 5-6-7 ) so I could remove mandriva bootloader.Since I did, I removed ubuntu (sda 7) since it wasn't necessary but after it gave me the grub file not found.Obviously yes, since GRUB was installed from sda 7 but i have another grub.conf on sda 5 and I would like to know how to change the path of the grub reader to sda 5? or must I install all over again de grub loader?
i am trying to change the boot order on the GRUB menu so that the countdown automatically starts on an older kernel. From what i can see all the solutions on the web want me to edit the /boot/grub/menu.lst file. The problem is that i don't have one. Someone also mentioned that if i don't have a menu.lst file then i should look for the grub.conf file. I don't have on of those either. The closest thing in /boot/grub is grub.cfg but that looks nothing like the descriptions i have heard of /boot/grub/menu.lst file
I had to dual boot my computer again with windows unfortunately for school. This is something I've dealt with dozens of times in the past but when I try to recover grub 2 with the ubuntu live cd I get this:
I've been trying change the default OS in GRUB. I changed the value for GRUB_DEFAULT in etc/default/grub. However, when I run update-grub, I get the following error:
So I got my DOS 6.0 entry in... but Grub reports file not found. I assume grub is fine, and DOS6 was working and I haven't done anything to it. Needless to say, I'm guessing that I'm telling grub to look in the wrong place for the dos bootloader. Here's what I have in my 40_Custom file:
Just before the computer boots into the grub menu, I noticed a message on the prompt saying that a file was not found. I had reinstalled Ubuntu 10.04 prior to this. Maybe the grub was not configured properly but I don't know how to fix or find the missing file. I also noticed that I don't have /boot/grub/grub.cfg.
My problem now is: After booting my laptop, Ubuntu doesn't load and i'm stuck in a GRUB command prompt and not sure what to do. If i type "boot" I get "error: no loaded kernel"Here is how I got there:1. I ran 9.1 healthily until I was prompted to do an upgrade. I ran the upgrade but some packages weren't authenticated so I ran a partial upgrade. 2. I reboot but I'm faced with "Error 15: File not found". After some research and going through the forums, I thought I found the solution by following these instructions to copy the GRUB files from the Live CD (https://help.ubuntu.com/community/Gr...0from%20LiveCD)3. Once I completed this, I'm now stuck at a grub> prompt when rebooting (the error 15 has disappeared). (the screen header informs me i'm dealing with "GNU GRUB version 1.98-1ubuntu5"Any thoughts on what I might have done wrong? From my reading today, I might have installed GRUB2 (even though Grub legacy would have been appropriate?). What is the best way out?
Whenever I try to boot my computer, GRUB (Version 2) says "File Not Found". It does this for all entries except the Memtest86+ entries, which work fine. I have tried reinstalling GRUB, but it still does the same thing.
Have a Dell Inspiron 4100 laptop. 1GB RAM and 1 Ghz processor. Has a working install of Oracle Enterprise Linux 5.4 OEL uses Grub version 0.97 My OEL install works well and I do not want to make any changes to it such as upogarding GRUB to a later version etc.
I have installed Xubuntu mini and this completed without a problem.
I have a single hard drive.
I went into OEL and mounted the Xubuntu root drive so I could see the /boot/grub/menu.lst file.
I copied the entries for the main xbuntu kernel etc and pasted them into my OEL grub.conf.
I am doing this so someone else can borrow this laptop for internet use for a few weeks and OEL is not very user friendly and also want to protect my install.
I am reading spc456's thread with the same subject line and trying to work through the thread with suggestions by drs305.
My situation is very similar. It started with a sudden Windows boot problem (still my primary OS):
Quote:
This was only if I selected Windows from the boot menu. I thought I could cure it with the Windows-7 Repair Disk from neosmart.net. This appears to have wiped my Boot partition completely and now I can't boot anything. (I'm using the Ubuntu 10.10 live as I type this.)
I downloaded boot_info_script055.sh and here are the RESULTS but I don't know what needle to look for in that haystack.
Code:
Boot Info Summary:
Well, I see why the Windows boot didn't show up. Looks like 30-OS_prober was failing to find the Windows boot record, which makes sense if the whole blessed (ahem) boot partition has been hosed.
I tried to follow the grub-install instructions:
Code:
But since grub2 is obviously not going to find the Windows boot record, I will continue with drs305's.
Code:
No, I have not mounted /dev. Where would I do that? Against which FS?
In any case, I am now printing the article "How to restore the Ubuntu/XP/Vista/7 bootloader" to see if I can get that going.
To my dismay, I discovered that the disk supplied with my Dell machine is NOT a Windows Installation disk, so no straightforward "fixmbr" command will be possible at this time.
I'll let y'all know how I have fared with this. I am sceptical because it's not merely the master boot record that has gotten corrupted but the whole blessed (have I used that adjective already?) boot partition.
I did an upgrade and now getting grub error 15 file not found on boot, memtest runs ok. any help would be appreciated. system information is listed below:
I have been using various versions of Ubuntu for many years. I love it and I want to stay with it. Now I need help more than ever. So basicly I've searched through forums and other sites which seem to have had the same problem I am having.
However, I've tried all the "fixes" and nothing works at all at this point.
Here is what I have tried so far: [url] and every suggestion here: [url]
When I put in "sudo fdisk -l" I get this:
So after trying the suggestions in the above links I would restart and still get: "error: file not found. Grub rescue>"
I am trying to install it from a usb to an external hd. I installed Ubuntu 8.4 on the same hd before and it worked fine however I need one of the newer versions to use the programs I need. I've been at this for hours and maybe I am just missing something simple.
I've had my Ubuntu crash and had to reload it. I;ve reloaded 9.1 and am now getting the error
GRUB loading. error: file not found grub rescue>
I have tried a number of solution attempts I've found on the internet with no success.
I have Windows 7 also loaded however I'm not getting a Grub menu only the error above. I seem to have a number of Linux partitions I believe my correct one is on sda7. I had at one stage tried to have a boot partition on sda4.
The first is I seem to have 3 GRUB installs. So whilst I update the one from my live session, the change does not appear in the boot up menu. I had installed 10.10 from a CD into a different partition (sda6), but that will not boot, so I have just deleted this and done another grub install and update. The kernel I am using has just been updated from 10.04 to 10.10 too, and it is this that I use and the Grub I have been working on (sda5).
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.
Been trying to solve this using Google for a while. Well, I recently did: sudo apt-get dist-upgrade. Now, whenever I boot up I get "Error #15: File not found."From what I've gathered, something is wrong with my menu.lstI've tried several things to fix this, but I can't figure it out.
I already had ubuntu 32 bit version 9.10. but due to some tool compatibility reason I need even the 64 bit version 9.10. I dint want to delete 32 bit version so I wanted to install both on my system. I have windows vista as well.
So I booted with 64 bit version of Ubuntu, went on with the installation, until the point were it asks to choose the partition. 32 bit version had 16GB allocated and 10GB free. so I thought I will make new 8GB partition from the 10GB free space. So I selected the partition and clicked on change, and specified 8GB and ext4 format and mount point as "/". I clicked on continue and in a few seconds it popped up with an ERROR message, which I can't remember exactly, but it meant to say that it could not make the changes as the disk to which the changes were made is in use. So I should not use it until I reboot. So I rebooted and now I have grub error : file not found and grub rescue> prompt.
I tried to boot with the 64 bit CD again with the option of trying ubuntu without making any changes and it does show the 16 GB partition, but when I mount that partition I do not see any folders in the partition except for a folder named "lost+found". I try to view the contents of this and it says I do not have the permissions.
I just (basically) completely uninstalled my OS by accident. In synaptic package manager I selected to completely remove volume control (which had been going haywire for god knows what reason) with intent to immediately reinstall. I didn't put 2 and 2 together when it said it'd remove all related files including the kernel... hal... restricted drivers... everything got uninstalled. Network manager crashed...
I decided to try my luck with restarting (what was left) of the system. Now I'm looking at a boot screen of: loading grub... error 15: file not found.
Did I have to just make a boot disc and reinstall the os? or can I just "put the pieces back together" as it were and reinstall with a 'sudo aptitude update' once I get network up again?
I have two partitions installed on my computer, Ubuntu 10.04 (part. sda2) and Windows XP (part. sda1). When I restart my computer I get this message: error: file not found grub rescue>
I thought this must be a grub error, so I booteda Super Grub disk (v 0.9799). Then I tried to fix grub with the Super Grub disk, but I got this message: Error 15: File not found Booting 'not lucky' pause SGD has NOT succeeded SGD has NOT succeeded
I then booted the system using an Ubuntu live CD, version 10.04.I tried to repair the sda2 Ubuntu partition. At a terminal prompt I ran [code] sudo e2fsck -f -y -v /dev/sda2. This did not work. It ended with "e2fsck aborted". I could not repair the Ubuntu partition, I tried to open the sda2 partition by running the terminal command [code] sudo mount /dev/sda2 /mnt. I received the following message:
mount: wrong fs type, bad option, bad superblock on /dev/sda2 missing codepage or helper program, or other error In some cases useful info is found in syslog - try dmesg | tail or so
Using the ntfs-config program, I can easily mount the Windows XP partition (sda1). It mounts and I can read or write the files on the Windows XP partition. So at least Windows XP is not damaged. I downloaded and ran the boot info script, and here are the results:
Code: Boot Info Script 0.55 dated February 15th, 2010 => Grub 2 is installed in the MBR of /dev/sda and looks on the same drive in partition #2 for /boot/grub .....
I've setup raid to my primary partition by starting up from an USB. Array was up&working. Now starting up from my HDD's, I get: error: file not found. grub rescue> what should I do here?
I am using Ubuntu 10.10 dual booted with windows vista. My boot is in a separate partition (sda5). My computer told me that there was limited space on that partition so I tried to clean things up using apt-get by removing old kernels. Turns out I didn't do it correctly because I consistently get an 'ERROR 15' when I shut down and rebooted my computer. I have a live-CD USB-stick so I tried reinstalling grub, (grub-install) updating the menu.lst (update-grub), and manually going through menu.lst and changing to root=(hd0,4) and groot=/dev/sda6. But I still get this ERROR 15 when I reboot.
when I do sudo grub find /boot/grub/stage1 find /boot/stage1
Both give me an ERROR 15 message and I'm not sure how to proceed with a diagnosis. When I ran update-grub, occasionally it used to tell me that /etc/fstab may be incorrect. Here is /boot/grub (note that stage 1 does exist!) ( this is /dev/sda5)
I just installed debian from debian-live-8.2.0-amd64-standard+nonfree.iso and after installation, which finished without problems, I cannot boot the system. I get the error:
Code: Select allfile '/boot/grub/i386-pc/normal.mod not found
From grub-rescue via ls command I see that I don't have the i386-pc folder inside /boot/grub. I have only two files: unicode.pf2 and grub.cfg
I am unable to get a knoppix poor mans install to boot using grub and opensuse 11.3. I have tried the same method on another box, same opensuse 11.3 and it boots fine. However, no matter what partition I put the knoppix files in on the problem box, it is the same error. I also have several opensuse kernels listed in the grub menu that were added when the kernel was updated, so the knoppix grub entry is off the screen. I have to down arrow to list the knoppix entry. I read that with this kind of error using ubunto as the host system, that running update-grub will force grub to look for bootable kernels and add it to the menu of boot choices. Does the same fix apply to opensuse 11.3? I have two versions of puppy linux working on this box as a poor mans install, so I am at a loss why it will not see the knoppix kernel. Can it be a problem of too many kernels listed in the menu.lst file? This box is a live update from opensuse 11.0.
I have a new installation. I try to boot and instead of my grub menu, I get "error: file not found" and am dropped into the rescue prompt. I have just a standard "Desktop" installation. I installed from the 5.05 net install cd. I installed grub to the MBR.
partitions are: hd0,2 is / hd0,5 is swap entering the "set" command results in: prefix=(hd0,2)/boot/grub root=hd0,2 [Code]...
I would like to modify the boot loader settings and triedo open the file grub.confHowever, it is said that the file could not be opened, as seen in the attachment.Tried to authenticate as 'root' before opening the file, but the problem still exist...
