Ubuntu / Apple :: RFIt Partition Tool Not Working - Error: "MBR Partition Table Is Invalid, Partitions Overlap"
Aug 23, 2010
I installed Ubuntu as shown in the wiki and when I went to restart it gave me a lovely blinking cursor and nothing else. So I held down option, loaded into osx, reinstalled rEFIt and got my menu on startup. Unfortunately, the partition sync tool doesn't seam to be working, it gives me an error: Status: MBR partition table is invalid, partitions overlap. Error: Not Found returned from gptsync.efi

I was reading another thread about someone with a bad partition table and I decided to join this forum. I'm not going to take any drastic actions with the partition (/dev/sda3) in question. I am going to wait for instructions on what to do first. I am not very good with Linux and need some hand holding. System: DELL 4550 Dual-Booted with XP and Ubuntu. Works OK, just no swap. Well, here's what I did: I deleted a partition for Windows XP Pro because it was a trial, and it ran out. I then decided to slide the swap partition for the Ubuntu Linux that I dual-boot into over. (If this was successful, I was going to try expanding the root partition to take up the unused space.) I used Gparted on a CD to do this, as I figured it was safe to do.
I now cannot mount the swap space at bootup (and have to go into a backup version of the OS), although I can use Gparted in Linux to execute the "swapon" command, and it appears that it worked because I now see "swapoff" as an option on the context menu. (I actually don't even need a swap partition, except to hibernate.) If I highlight the swap partition and click on "Drive" on Gparted's menu bar and select "Create Partition Table", it will erase all data on /dev/sda, so how do I fix the bad partition table non-destructively?

I'm trying to clone a Linux install to a different laptop. It's made a little complicated by two facts:
1) The 'new' laptop I'm trying to copy my Linux installation to is actually older and has a smaller hard drive then the computer I'm copying from
2) The computer I'm copying from has both a windows and Linux installation; I only care about the Linux partition.
I figured I would copy only the Linux partition from my primary computer to the laptop, sense the laptop doesn't have a large enough hard drive to copy everything. So I used the DD commands to copy SDA3 (main Linux partition) from my main computer to SDA2 of my laptop. When I came back a few hours later I was surprise to find my laptop trying to reboot itself (I never turned it off). It would keep starting to reboot, failing, and restarting itself. Not too surprising sense its boot partition wasn't changed so it's trying to boot into centos when I copied a redhat partition to it.
The problem is that when I used a redhat boot disk the rescue mode was unable to find a Linux partition to mount. /dev/sda2 exists, but trying to mount it gets the complaint "No such file or directory". "fdisk -l" lists sda1 (the boot sector) and sda2. Sda2 is the correct size and reports Linux LVM for its system. But "fdisk -l /dev/sda2" gives the error message "Disk /dev/sda2 doesn't contain a valid partition table" Did I not clone the drive correctly, or was an error caused due to the boot sector not being copied yet (the laptops boot sector is smaller then my old computers, so I can't copy from old computer to laptop)? Can I salvage the laptops partition table somehow, or do I have to repeat the cloning process? And if I do have to re-clone my computer can anyone tell me what I did wrong the first time so it works this time? I don't care if I copy just the Linux partition or both windows and Linux. Even though my main computer has a larger hard drive I'm only using about half of its available space so it should be possible to copy both partitions if I could ignore the unused sections of the harddrive.
Edit: I used DD to copy a tiny part of the Linux partition from my laptop so I could look at it. Most of it is illegible binary of course, but I scrolled through till I found some text right near the beginning:
Code:
VolGroup00 {
id="F2MWxh-....-BidcLe"
seqno = 1
[code]....
So it seems that the DD command did copy everything over to the laptop, which is good to know. I noticed that it says device="/dev/sda3" right in the middle of the code I just posted. The Linux section of my original computer was SDA3 but I copied it to partition SDA2 of my laptop. So is the problem because the boot partition is for the wrong device? I don't suppose if I modified that one line to say SDA2 it would be able to load correctly? (Not that I know how I would modify the line, short of using the DD command again).

I have had a problem whilst trying to rewrite the MBR on a NTFS-only harddisk which has one partition.
I'm wondering if I can do anything to fix the problem from my ubuntu CD which gives me access to a shell - using the trial/demo mode.
The problem is that I can't boot into WinXP since using the XP boot cd to go into recovery mode and typing in 'fixmbr DeviceHarddisk0Partition1'.
All I get is the message code...
Thought perhaps there may be a way to restore the missing signature or something, from ubuntu.

I have just installed the newest Debian Stable 7.8 release on my new notebook. Before installation I had to free some disk space from the preinstalled Windows7 with ntfsresize and fdisk. In addition to the existing three primary partitions I created an extended one with three logical partitions for /(root) /home and swap, see the output of 'fdisk -lu'
Code: Select allDisk /dev/sda: 1000.2 GB, 1000204886016 bytes
255 heads, 63 sectors/track, 121601 cylinders, total 1953525168 sectors
Units = sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 4096 bytes
I/O size (minimum/optimal): 4096 bytes / 4096 bytes
Disk identifier: 0x196585ba
[Code] ....
Partition table entries are not in disk order
For some reason I put a bootable flag on sda7, and the only small concern during installation was that some BIOS systems might not work with boot-flag no logical drives. Now, every time I boot I get this "Invalid partition table!' message which I must 'enter" away before I get to the GRUB menu.

Is there a difference between using GPT partition table when formating hard drives and MS-DOS partition table? What are the advantages/disadvantages of using either?

I have a laptop with dual boot system, opensuse 11.2 and windows xp in the same hard disk.
I tried to remove suse doing the following :
Ι loaded windows xp cd and get in recovery console. After that i did Fixmbr and fixboot.
After that, after the bios screen, i get a black sceen with the message "invalid partition table"
If i type a "dir" command i can see my files, so the disks partiotions are not corrupted i guess. Just the MBR is damaged.

I want to change my sda2 partition to ntfs type. i have installed GParted but it is returning a strange type of error. Here is the error dump file...

Is there a program that will reread the partition table and update the kernel even if one of the unmodified partitions is mounted? I installed my system on one partition, then I added another with free space. Now I want to format the second partition, but the kernel doesn't know about it yet. I tried sfdisk -R /dev/sda, but it refuses while the root partition is mounted. Is there anyway I can avoid rebooting?

I have tried to automate the configuration of a usb drive with not much success.
The problem that I have is that I have a large amount of usb drives that have a partition table of type "loop" and I need to change them to "msdos". The size of the drives vary and I need to use FAT32 or FAT16 file system.
I've tried various partitioning commands and gui applications but cant find one that I can give a one line command to to set the partition table, maximum partition size and file system.

Everything is installed and setup on my system, but when I setup my partitions I chose my Windows partition to be bootable. Can I just use cfdisk to toggle the bootable flag so my linux partition is bootable and rewrite the partition table?

What I believe has happened is that I've corrupted the partition table. Essentially one of my partitions' ending point exceeds the maximum number of cylinders/sectors on my drive.
Essentially I have the same problem as on the thread @ [url] but do not know how to fix this and am afraid to reformat/partition based on sectors without really knowing what I'm doing here.

When I try to look at SDA in GParted everything shows up as unallocated (though it's obviously not) and it says

I was having trouble creating a USB Startup Disk in Ubuntu and used the command:
sudo dd if=/dev/zero of=/dev/sdb bs=1M count=1
This was a mistake as my USB flash drive was on /dev/sdc. If I am understanding this correctly, the command above deleted the MBR and the partition table. This disk had a single "/storage" partition on it. I googled a solution and found that the "testdisk" program seems to be the most popular solution for things like this. I ran it, selected an "Intel/PC partition" type, set the partition to a non-bootable primary Linux partition, wrote it, and rebooted.
Whenever I run:
sudo mount -t ext3 /dev/sdb1 /storage
I get:
mount: wrong fs type, bad option, bad superblock on /dev/sdb1, missing codepage or helper program, or other error In some cases useful info is found in syslog - try dmesg | tail or so
Dmesg shows the following:
[20246.273941] EXT3-fs error (device sdb1): ext3_check_descriptors: Block bitmap for group 1 not in group (block 0)!
[20246.279376] EXT3-fs: group descriptors corrupted!
When I run:
sudo fdisk -l /dev/sdb
I get:
Disk /dev/sdb: 400.1 GB, 400088457216 bytes
255 heads, 63 sectors/track, 48641 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

USB flash disk partition disappeared as well as partition table I'm not sure about the cause
Code:
root@u# less /var/log/syslog
usb 5-1: New USB device found, idVendor=058f, idProduct=1234
usb 5-1: New USB device strings: Mfr=1, Product=2, SerialNumber=0
[code]....
Where did the partition table go? The device had one ext3 partition something around 4GB(size of USB storage device). I need to restore few files from this device.

This was a really frustrating problem which turned out to have a really simple solution, so I'll share it with people who might be having the same struggle. Problem You plug in a usb hard disk and try and mount it using:
[code]....
I spent hours - days - hunting around for the solution! (And felt a bit humiliated when I realised how simple it was!) PS, There used to be a "Success story" section on LQ, but I couldn't find it; if this is better in another section, please move it. PPS, I'm on a public computer and won't have Linux access for a looong time - if anyone can copy the message that fdisk prints out to help people who are searching for it

i used to have ubuntu 9.i decided to move to sabayon so i used the live cd to install it ,resize the ubuntu partition and use the remaining space for sabayon.while the resizing procedure i got an error(i dont have a copy of the error log file but i know it has something to do with an anaconda process).i aborted the installation and the result was an filesystem that couldnt be mounted.when i try to mount the hdd i get this:
Code: Error mounting: mount: wrong fs type, bad option, bad superblock on /dev/sdb1,
missing codepage or helper program, or other error
In some cases useful info is found in syslog - try
dmesg | tail or so and this is what i get from fsck: Code: $ sudo fsck -f /dev/sdb1

I've used rEFIt and to create a dual boot system on a new MacBook Pro 7. 1 following the directions in the community forum. I can book ubuntu and mac os x fine. However, the MBR boot table shows an error in the partition map.
[Code]...
How can I fix this, rEFIt and gptsync are unable to repair the MBR error... Will this cause problems (since MBR shows the ubuntu boot partition overlapping the OSX partition)?

I originally had an Ubuntu partition on my hard drive which occupied about half of it. I installed Windows 7 in the remaining unallocated space and I was planning on doing a grub update from a live cd afterwards. BUT when I looked at my partition table, the space where the ubuntu partition used to be is now unallocated space!

I was trying to create a partition on my hard drive on Linux using the GParted program. I noticed my hard drive had a key next to its name but could not find information regarding it online. I proceeded to unmount the drive and made 2 partitions. However, it game me an error saying it couldnt make the partitions. I turned my computer off thinking i would get back to trying tomorrow. Today i turn on my laptop and see the usual hp screen. But after that it goes to a black screen with a blinking underscore looking thing. It goes nowhere from there. It usually goes to a black screen after the hp logo, that says GRUB loading.

I had a RAID controller in a system that would not load Virtuozzo. So I deleted the array created by the 3Ware 9550SX controller before removing it and one drive from the CentOS 4.8 server. Even though I deleted the array when the server boots it shows an error:
ERROR : asr : invalid RAID config table
How can I clear and remove the table without having to reload the OS? Can I? Di I need to run the Seagate Tools and reset the drive?

I got swap space full error and the ubuntu version of "blue screen of death". I used Disk Utilities to delete a 2.1GB unused partition. When I tried to create a swap space partition (with Disk Utilities) it failed. In the mean time ubuntu did some security updates. When I tried to create again Disk Uilities did not complain but only created a small ~ 500 kB partition. I deleted that and reboot and got "unknown filesystem grub rescue>". I booted from a USB key successfully. Now Disk Utilities and File Browser can see all the partitions and files on the hard drive, but GParted thinks the entire hard drive is unallocated. I vaguely remember that there are two partition table on the hard drive. It may be that one of them was deleted (when I removed the ~ 500 kB partition with Disk Utilities earlier maybe?). It seems at least the other partition table is still intact since Disk Utilities and File Browser can still see all the partitions and files. Is it possible to restore the deleted or damaged partition table and make the hard drive bootable again?

I Inadvertently deleted a good partition while trying to clean up after a 10.10 update install failure that left grub broken and prevented me from using my working Linux partition. (installed 10.4 in a new partition) Used testdisk to restore the deleted partition which resulted in the entire partition table being wiped out.All partions are gone, win Xp, 2 Linux partitions, 2 Linux swap partitions.Testdisk deep search does see the partitions but will not recreate the table.
Is their anything I am doing wrong in Testdisk that it won't write the table?Nothing else has been written to the disk.I very carefully recorded the partition information - is their any way to manually enter?

I've installed Linux quite a few times on many different computers and for some reason, I'm stumped.
I went to ubuntu.com and burned myself a boot-disk. Afterwards I went to my dad's original ME box and when I tried deleting the partition I got an error that said, "Could not change partitions, cause the disk could not be locked".

I've been googling all afternoon to fix this error I get. The situation is as follows: I have multiple harddrives (3x320gb and 1x160gb) all on the SATA interface. One of these drives contains Windows, and the rest I use for programs and downloads. I've installed Ubuntu 9.04 from a USB-stick using the installer's partitioner to make some room for Ubuntu (Ext4 filesystem). I've tried Ubuntu and SUSE in the past.
