Ubuntu :: "boot Sector Signature Not Found (unbootable Disk/partition)"
Jan 3, 2011
I recently installed meego on an asus eee pc, neat l ittle os. i had originally had grub set up booting into ubuntu netbook remix. win xp and the system restore partition. when i installed meego i was allowed to select what i wanted as far as boot options in the new boot loader (extlinux). windows and meego boot just fine but when i try to get into my already configured and homey install of ubuntu nbr it gives an error of
"boot sector signature not found (unbootable disk/partition)"
upon adding the installed VL on the existing LILO.. (btw i have not installed its LILO on the installation setup) since i know that i will just add it to the "existing" LILO the error above arises upon doing the lilo run command.$adding Vector6.0 etc.FATAL : Boot sector of /dev/hdc13 doesn't have a boot signature.i have tagged the /dev/hdc13 bootable via CFDISK. but same problem arises..
I recently installed 11.3 on an external drive. After adding some software in yast (searched Kernel and checked every option), I was prompted to reboot but the no boot sector found error came up. Tried reinstalling with the same result. Grub is boot loader
I'm running 9.10 off of a 4 GiB CF card. I keep running into space issues with updates, so I purchased an 8 GiB replacement card. I've cloned the 4 GiB card to a .IMG file using DD.I've then copied the 4 GiB image back to the 8 GiB card using the Ubuntu startup disk creator program. Once done, I'm able to properly boot off of the new 8 GiB clone.Unfortunately, the clone ends up with 3.67 GiB of unallocated space at the end *see attached). I tried deleting the "extended" partition that the swap is located at after booting from a Live CD and the system was unable to boot after this. I was thinking that I would delete the swap entirely and create a swap file after I merged the existing partitions, but I was unable to do this.
best way to do this (e.g. get one large 8 GiB partition with my old image on it)? I still have the original untouched 4 GiB card and also have an external CF drive if I need to redo the cloning. I've also used Clonezilla before, so perhaps there's a way to do this that allow me to grow the image as it's being cloned.
I was using the disk utility on Ubuntu 10.04 and wanted to make by 500GB external NTFS formatted USB drive into 1 x 50GB FAT32 and 1 x 450GB NTFS. I clicked the option that said format or create a partition and it basically wiped the whole thing in a split second leaving me with 500GB of seemingly empty space. Obviously the files are still there but I cannot boot the drive to view anything. I have downloaded testdisk, but don't know how to use it, but I am sure there is a relatively simple solution here. I am currently repairing the boot sector of the drive as Test Disk showed the drive as "no type" i.e. not FAT/NTFS/ext4 etc., but shows the correct amount of used space though, but I cannot view anything err go, I cannot use the undelete command as yet.
I had ubuntu studio installed ( for the record I hated it and every ubuntu flavor I have ever used. ) After backing off all the stuff from my home dir I started to install testing from a dvd. ( Is there a net install for testing? I couldn't find it) Don't ask me how it happened but some times I would have two grub graphical boot menus. One would chain to the other. I suspect that happened from one of the very friendly updates ubuntu did. Well when I tried to install testing I got a red screen telling me that grub wouldn't install so I tried lilo. Well it wouldn't install either. Back in the old days when I was a slackware guy installing from a stack of floppies I had a trick to wipe out any boot loaders or other stuff that gave me a problem. I would dd if=/dev/zero of=/dev/<drive info such as hda with no partition number> .
This would write zeros over the drive and it would look like a new drive. So I did this trick. But still no joy ( this is a clue, dd was also thinking that the beginning of the drive was after the boot sector.). I suspected that the installer wasn't doing it's job right. So I got a PCLinuxOs disk and started that installer. The PCLinuOS installer has a cutesy visual bar that shows the partitions. Well sure enough the boot sector showed as blank. This was what the Debian installer had done. It left the boot sector blank and tried to install the boot loader right after it. This won't work. Now I consider when some version of Linux falls on it's face and another version does it right that the version that fell on it's face has a problem.
One might even call it a bug. But I don't know what to do about it. I don't think the problem is with grub or the installer itself. I think how the drive was looked at was faulty. That's why dd didn't blankout the boot sector. So what do I do to help get the Deb people to fix this? The more I think about it the more I think the problem is with udev ( what a surprise) I think this because I suspect dd looks to the info set out by udev to find the beginning of the drive.
I have three disk in my system. One SATA (250GB) and two SCSI (73GB) disks. The Two SCSI disks were installed originally and RHEL3 is installed on it. The SATA disk is installed a few years later with RHEL5. As you can see below, the boot sector is still on one of the SCSI disks (sdb1).
I was using 2.6.28-14 kernel version, it update me to 2.6.28-15. Now I have upgraded kernels many times, not first timer, but this is a first to me. So I have this wierd system setup, don't ask. Where I use lilo instead of grub, just take it as it comes guys, I have to. At any rate, it upgraded all fine, and I restarted, play the blues I got a "No setup signature found" error and lilo won't boot. So I did some searching on web and everyone says to boot up CD and re-install lilo. Well with grub I've done this many times, no prob bob, but lilo won't work.
So I used my super auto grub CD to try to re-do things. Since grub config and grub was still installed on my Linux partition I tried it right. No go of course, grub says it can't find the partition nor can it mount it. So I tried the beta of lilo on the grub cd and it don't work either. Botched it up worse, first it wouldn't do anything on my second drive, just sat there black screen. Then I did it a second time, let's screw it up some more right. Now it doesn't even find a boot loader in the MBR ha ha.
So at any rate, how in the sam heck do I fix this thing? Short of downloading 10.04 and re-installing everything?? Don't want to do this, too much work when I can just upgrade and keep my stuff installed and setup. So I tried running jaunty from CD and re-loading lilo. So everything is working fine right, I mounted drive and apt-get install lilo and ran lilo. So lilo even telling it what config file to use and where won't find things and won't re-install. So just for grins, even though I thought it wouldn't work I mounted my second drive linux partition, the one with the boot info on it, you ready, to root "/". Then I couldn't unmount
I have a 160GB harddrive which I installed a F12, would like to upgrade to a bigger drive, but I hate to have to re-install everything.
Recommend a good disk copy utility? The utility should be able to not only copy files, but boot sector and everything. So I just need to make a copy, change my BIOS to boot from the new drive and run everything as before.
After realizing 10.04 Final doesn't support Intel 855 graphics card the hard way (upgrading to 10.04 from 9.10), I did some very silly things and now cannot even choose past kernals or go into failsafe graphics mode (which had worked prior to this).Long story short I screwed up GRUB. Because I am an amateur end user.I still have the 10.04 live cd. Can I reinstall this to put GRUB back to the original state?
I have installed vmware in windows server 2003 enterprise edition. When I installed I changed the default installation folder from c: drive to i: drive, as I do not have space in c: drive. After I captured red hat linux cd in vmware and reached partitioning section and continued I got a message like "an error has occured no valid devices were find on which to create new file systems, please check the hardware for the cause of the problem". The machine is IBM server....
Added an SSD (dev/sdc) and decided to move some less often changed directories there. Started with /usr and /boot, leaving / on a primary in the first drive, for now. All started ok, and my changed fstab mounted the right ones, and the system works.
However, grub is actually using the original /boot on / on sda1. I cannot see any way to change this. (Which makes it sorta hard to update the kernel
Okay, since it has two choices, I tried to tell it which one to use. But, grub> root (hd2,5) does nothing.
what I seem to recall, grub doesn't care about the boot flag on the disk. Nor does it care about primary vs. logical (except GNU doc says "makeactive" only works on a primary?).
The GNU doc also indicates that it looks for a directory /boot on the partition, so if you're mounting a partition as /boot, it also needs to contain a /boot directory under it. Tried that, but no change.
Is my problem the logical partition? Does that prevent "grub> root" from changing it? I'm afraid to wipe out the old /boot and find that I can't start up.
I have a small project that I am trying to do for my job to help us out. Basically, I need to make a tool that lets me view all the sectors of a hard drive in hexadecimal format to make sure they are all zero after a low-level format. I need it to be very minimal, and display the data in a way that I can scroll down and skim through the sectors. Doesn't have to be pretty, just functional.I need it to do more things down the road, but this is the first hurdle I need to overcome. I would like to create a GUI interface so it looks nice, but first I am only concerned with the sector viewing function. I am not entirely sure where I should start.
I see there is a tool called dd I could use to read the hard drive and I am wondering if I need to use that, or if I can just open /dev/hda as a file and be able to view all the sectors that way.Also, just to clarify, I am wanting to write this tool for linux,specifically DSL. I need it to be a very small distribution that can be loaded quickly from a usb drive, cd, or over the network with PXE.
In the past I have been able to succesfully install ubuntu on several external usb drives with up to 500gb in size.Now I am trying to install a copy of ubuntu 10.10 on an external usb iomega 1tb eGo drive but I am having major issues.The installer reports the total disk size as only 124 gb, instead of the 998gb that gParted reports for the same disk. Proceeding with "use the full disk" installs ok, but it doesn't boot.Grub2 reports that it cannot find the kernel.After some desperate attempts to repartition and after some googling I think that the issue may be with the sector size, which fdisk -l reports as 4096kb (all my other drivers report 512kb) and I have the impression that linux is not ready for it (or I lack the knowledge, which seems more likely).I have also tried to install fedora 14. This distribution reports the correct disk size, installs properly, but again, it cannot boot (Fedora uses grub, not grub2), with a very similar message to the grub2 installer.Because of the way I work, I need my external usb drive to be able to boot linux. And I find it difficult to believe that linux doesn't handle 4096kb sector disks, so here I am asking for help . Please note I am not a linux expert.
2 months ago, I built a dedicated backup server using 4 2TB SATA drives for software RAID5 (6TB total). A few days ago, smartd sent out mail saying it found an unreadable sector on one of the drives. I ran selftest using smartctl and the error persisted. So far, neither software RAID nor ext4fs running on top of the RAID volume have reported errors.
MOST OPTIMISTIC: It is normal to have a few bad sectors among billions. Software RAID takes care of alternatives. Keep using the system until RAID spits a more serious warning in the future.
MOST PESSIMISTIC: It is a really bad sign to lead a disaster. No good disk drive should have bad sectors especially when it is only 2 months old. The error is simply not detected by software RAID and ext4. Replace the drive immediately and return the bad drive to the supplier.
I have just clone from my previous IDE hard disk to a bigger IDE hard disk with clonezilla. However, when I boot my system with the new hard disk using the installation disk, it says an error that "no linux partition found on hard disk".
Slackware 13.1,using "sfdisk".I need to use this one as it can be used in a non-interactive mode,"parted"is not a solution for me.Inside my own script I make the partition like this:
# MAKING PATITION: set `losetup -f`; dev=$1 `losetup $dev $out` sfdisk $dev << EOF ,,$fsys EOF
However after formatting this single partition in FAT16 I can see the drive in my emulated Windows311, but not use it. It says that the drive cannot be accessed. When I do the same thing interactively with fdisk it all works. When inspecting the partitions in both cases via "fdisk -ul" I see that whenever sfdisk is used to create the partition it is created starting from the 1 sector. Whenever fdisk is used it is created from 63 sector (which is correct of course). How can I make my sfdisk start the partition not from the 1st sector, but also from the 63 so that OS wouldn't have problem with that?
I tried like this:
sfdisk -uS $dev << EOF 63,,$fsys EOF
But it then just says that the partition does not end on the boundary. Trying to see the content with fdisk -ul says that partition table is incorrect. So doing it this way doesn't work.
Is there any hope of getting a WD10EARS 4k-sector disk to work properly as a secondary under Etch? Just wondered if anyone had a fix before I RMA and return it as "Not suitable for purpose" WD say it should be OK with linux. But it ain't. It gives very poor perfromance, with a lot of hesitation. The issue is apparently one of sector boundaries, but the exact details are extremely complex.
I just installed Ubuntu on my laptop (x200s, XPpro with 230 Gb), and created a 30Gb partition therefore. At the end of the install, the screen remained orange for a while, without any disk activity. I forced the laptot to reboot, but Ubntu was no option when the machine restarted. However, my XP partition has been reduced by 30 Gb. Does anybody have an idea about what I should do to either get Ubuntu installed or recover the disk space?
fdisk -l: Disk /dev/sda: 750.2 GB, 750156374016 bytes.
I've tried other installations, but I always get errors like this. /dev/sda 5, 7 and 8 are occupied by PCLinuxOs. /dev/sda 9, 10, 11 and 12 by Fedora. I made room for Linux installations by GParted (last version). Really, I made no errors. The installer of PCLOS is a bit strange: it changed the NTFS partition sda5 in sda 6! In a previous installation with Fedora and Kubuntu only the extend partition sda 4 complained about not starting on physical sector boundary. The hard disk is Western Digital with Advanced Format. Probably this is the cause of the problem. The systems are snappy and responsive. I do not encounter any problem. What to do? Ignoring the problem or reinstalling? May be it would be better to get rid of PCLOS and to dual boot Windows with Fedora?
I currently have XP installed on a NetBook (Samsung NC10), and would like to run Fedora on it. I'm currently looking at putting Fedora onto a flash memory card to test it works OK on the hardware, before installing it to the hard disk. The problem I've got is that the boot sector is occupied by WDE software (TrueCrypt). Will this pose a problem for dual-booting XP with Fedora, or will GRUB move the boot loader in the usual way?
I recently switched my secondary/kid's computer to run with linux. I am trying to download a game called wizards101 for them that they play frequently. I keep getting this message reading
Archive: /tmp/InstallWizard101-1.exe[/tmp/InstallWizard101-1.exe] End-of-central-directory signature not found. Either this file is not a zipfile, or it constitutes one disk of a multi-part archive. In the latter case the central directory and zipfile comment will be found on the last disk(s) of this archive. zipinfo: cannot find zipfile directory in one of /tmp/InstallWizard101-1.exe or /tmp/InstallWizard101-1.exe.zip, and cannot find /tmp/InstallWizard101-1.exe.ZIP,period.
I dont know what to do about getting it downloaded. I never had this problem downloading this game on windows.
I recently made the move from windows to Linux and I am happy to having got rid off all the MS stuff. Trying out a few distros I decided on using Ubuntu and Mandriva (wife likes the flashier stuff, what can I say ).
My question is how can I partition my hard disk in such a way that my /home is separate from both the Ubuntu and Mandriva part but accessed by both as my default home folder.
