Ubuntu :: 10.10 Will No Longer Boot - Partition Disappeared
Dec 2, 2010
I booted my laptop up this morning to find that Ubuntu 10.10 will no longer boot. Here is some background. I have a Raid 0 setup with sda and sdb. For the last day or two upon boot, it was asking me to run some file system checks (hind sight I should have just sucked it up and wait for it) but I canceled out of them as I have been extremely busy. Also, I upgraded my kernel to the latest available from the repos. I am not sure if the kernel upgrade has anything to do with it or just coincidence. I have booted up with a live distro on a USB stick and here is what I am seeing:
root@bt:/dev# ls -alh sd*
brw-rw---- 1 root disk 9, 127 Dec 2 10:44 sda
brw-rw---- 1 root disk 9, 126 Dec 2 10:44 sda1
brw-rw---- 1 root disk 8, 16 Dec 2 10:41 sdb
brw-rw---- 1 root disk 8, 32 Dec 2 10:41 sdc
brw-rw---- 1 root disk 8, 33 Dec 2 10:41 sdc1
brw-rw---- 1 root disk 8, 34 Dec 2 11:06 sdc2
brw-rw---- 1 root disk 8, 37 Dec 2 10:41 sdc5
root@bt:/dev# fdisk -l

Disk identifier: 0x00000000
Disk /dev/sdb doesn't contain a valid partition table
Disk /dev/sdc: 16.1 GB, 16125001728 bytes

/dev/sdc2 1873 1960 706860 5 Extended
/dev/sdc5 1873 1960 706828+ 82 Linux swap / Solaris
So I am able to see sda in /dev but fdisk does not see it. When looking at gparted, it only is able to look at sdb and sdc (my usb stick). The weird thing is that I also have Windows 7 installed on this raid and it is able to boot without any issues so I know the entire sda hasn't died on me.
I'm an unexperiences Ubuntu user havning installed a dual boot with Windows XP and Ubuntu 9.10. However, when I'm booting my system now, the Windows option has disappeared from the menu, and the list only contains many different updates of my Ubuntu system. Can anyone try to explain me how I can retain my Windows option?I onlyuse Ubuntu for programming purposes, so skills regarding this topic is very poor
I installed ubuntu onto a 20gb partition I created on my Macbook pro. Installation went great, but now I can no longer boot into my Mac partition. When booting up if I hold the option key, all that shows up is a lock icon with a white area below which I can type things into. Nothing happens if I do, and there are not hdd showing. The Mac partition is an option on my grub menu, however it hangs when selected and does not end up loading.
Note: I am on vacation from school at the moment and my live cds for Mac are in my dorm.
when i installed it the windows 7 Partition no longer works. I can see the windows 7 partition but when i click on it, it just reloads the grub boot loader. Im in college and need the windows 7 partition.
Now it seems as though all of my printers and my scanners have disappeared, also thunderbird will not open anymore. I find this very strange.. I can't even think of why this would happen.--When I start thunderbird it says starting thunderbird then does nothing.. if I try to start it again it says that it's already running.. which it is not..I have all of my updates updated.. You are using Ubuntu 11.04 - the Natty Narwhal - released in April 2011 and supported until October 2012.
I've been using Ubuntu 10.10 for just under a week. Recently, a partition called 'Data' has disappeared, and all my music and documents along with it. The folder is not to be seen in Places or on my desktop. My only way of finding it is to go to terminal. But when I try to open it there I get an error saying I don't have permission to read it. In Puppy Linux and SliTaz I can easily find the partition and read it. What should I do to bring it back in Ubuntu?
I had to reload my XP partition and my grub menu disappeared. I followed direction from this web page [URL]. I followed Method 1. After I rebooted I got a command prompt with a notice stating Minimal BASH-like line editing is suppoerted. When I input the final command of sudo update-grub I get the unknown command error. I cannot get to either XP or Ubuntu is there anything I can do short of reloading my ubuntu?
I joined the fedora irc channel and asked how to delete a partition. We actually decided that we could not delete the partition I wanted to delete because it was a root partition. After unmounting the partition, and one other partition with a really long directory name, all of my applications disappeared. I need a safe surefire way to resize a root partition. I don't want to unmount anything because we don't know if we'll be able to mount it again.
I have been backing up onto a 60G ext2/3/4 partition on a 1TB external USB hard disk for a year or so now and have built up a few folders of .thunderbird, .mozilla, and other assorted files - using this as my standard "backup system" - but suddenly all the files and folders in this partition seem to have disappeared.
In Gparted and KParted the partition shows up as the correct size with the correct amount of "used space" (= yellow coloured portion), as it does when running offof any CD/standalone OS. And the small bars under the volume names in Dolphin show about the right amount having been "used" too.But however I try to access this partition (or, to be correct LVM I spose:-)) it still always comes up as empty - ie 0 files in it. After months of working just fine.The NTFS partition on the same external USB sdd reads and writes quite OK/normally and also shows the correct amount of "used space" - but even from root I can't see any of the old files in, or read/write to the linux one. It comes up with "Denied"/"Can't Write to.." errors when trying to write anything to it.
I ran a freeware utility called DiskInternals Linux-Recovery from winDoze which, after half an hour, came up with a list showing all the folders and files in the partition. It said that they would be written back onto the hard drive that they were "retrieved" from - but no change happened - still no contents showing when booting up in any linux.

After having some issues with GRUB2 not showing my operating system list, I accidently screwed up my Windows 7 partition by selecting the 'Bootable' checkbox in thePalimpsest(?) Disk Utility.After finding this thread (and the links provided in responses), the problem appears to be the same but, unlike the user in that thread, I was unable the uncheck the Bootable flag after checking it - the partition became totally unrecognised, and the Disk Usage Analyser shows only ~5gb of HDD space in use.
I have no other Windows installation on my hard drive, apart from the Recovery Partition which existed when the PC was bought. The thread I linked to suggested that the bootmgr file may be on the partition of another bootable Windows partition (although I'm not able to get to the PC in question right now, so I'm not 100% sure if the Recovery Partition was flagged as bootable or not)What I need to know is:(1) Is it possible to solve this problem without having to re-install Windows? I don't really have many tools (or much knowledge about all these things) at my disposal, and have no idea how to access the Recovery Partition files in order to see if the required Boot folder and bootmgr file are there.Also, in the file explorer, my Windows 7 partition is no longer visible.
(2) If this is possible, do I require internet access on the PC itself? Ever since I installed Ubuntu, it has been unable to detect proprietary drivers for my network card (whereas the demo from the USB stick I installed Ubuntu with was capable of detecting proprietary drivers)
My desktop gets little use now but I had to do a clean install and found that grub no longer discovers a DOS partition. Even after install,a grub-update also no longer finds the DOS partition. Can anyone explain, or has this been dropped from grub. I do need that partition, rarely, I admit but still, it is needed.
I have (had) a dual boot computer;Win XP and Ubuntu 10.10 64 bit.I decided it was necessary to enlarge my Root and Home Partitions. Using the instructions http://ubuntuforums.org/showthread.p...ome+Partitions I successfully enlarged the partitions and restored 10.10 (I used the copy command suggested by Irony). However when I boot the computer it boots to Ubuntu but no longer gives me the option of going into XP(it is not listed in Grub menu). Is there a fairly straightforward way of getting XP back on the Grub menu so I can boot to XP again?
I have been running a dual boot 9.04/xp setup without major problems for nearly a year now.(just an unresolved kyocera printer problem)
I have had issues with windows and recently needed to reinstall windows. To do this I created a slipstreamed SP3 disk. I switched to boot priority to CD and ran a repair install from there, trouble was this gave me two installs of windows at the boot menu but ubuntu disappeared from the menu at this point.
I successfully ran the repair install again from the original windows install.
I then deleted the second windows installation.
Now it boots straight to windows without the boot menu at all.
boot up in to chameleon, lists only Mac OS X as a boot option. Reboot, load Ubuntu 10.4 install cd, get to a terminal, mount /dev/sda3 /mnt grub-install --force --root-directory=/mnt/ /dev/sda3
reboot, let chameleon come up, it sees both Mac OS X & Ubuntu partitions and I can boot to either or happily, now here is the problem... If I select linux and boot in to linux from chameleon, i am brought to the grub menu, where i can select the first choice which is normal ubuntu 10.4 and every thing is great... until I reboot and my linux partition no longer shows up in chameleon, as if tthe act of booting in to grub is changing something / deleting itself from the partition? and I have to do the whole thing over again. SO, not having to even go in to OS X, I'm not sure thats really the concerns more as I'm doing something wrong with grub.
I recently had a problem that was bugging me for several days. I figured that I should probably make a post on it in case anyone else ran across thesame problem. My gnome desktop was not showing up after reboot, and everytime I booted, I had to kill nautilus to get it to come back.
Code: killall nautilus After looking around for a while, I found this post: http://www.linuxquestions.org
I am trying to install a box here where my /storage partition is about 2.5T.I had setup the partitioning with suse, while testing, and all worked well.Now when trying to install CentOs 5.5 it gives me an error, that my boot partition is on a gpt partition and this machine cannot boot that.Also I don't see the option to create XFS partitions from the installer.Can 5.5 support GPT @ install time?
I'm sure I've done this before and never ran into trouble so it's not like I wasn't thinking, just something went wrong this time and I'm screwed. I'll post a fdisk -l to show ya what I mean.
[root@localhost ~]# fdisk -l /dev/sda Warning: invalid flag 0x0000 of partition table 5 will be corrected by w(rite) Disk /dev/sda: 1000.2 GB, 1000204886016 bytes 255 heads, 63 sectors/track, 121601 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Disk identifier: 0x624aa2e0
Well I tried to install Pclinuxos 2010 to the same partitions as Mint 7 and basically just over write it (this I have done before) but this time Pclinuxos says there is a bad block and it can't copy files to / (sda7) I didn't think much of it at the time and thought I would try to install it (Pclinuxos) on a separate 100 gb usb drive and it was a sucessful install.
After booting Pclinuxos I try to access my 1TB sda hard drive and I can ony access sda1 .....when I look at /dev/sda in gparted is shows the whole disk as unallocated.I have done nothing at this point in time other than what I just said because I am very afraid of loosing all my pictures and everything else on that disk....and for those that will say always back up ....if ya think I'm not kicking myself right now your dead wrong......
I've decided to give ubuntu another test drive now that I got a bigger and better desktop. I downloaded the latest version of ubuntu, loaded it into my usb stick and booted from it. I then clicked on the install icon on the desktop to start the installation. Everything was going ok, until I came to the partitioning part. I had already (on windows 7) created a separate partition for ubuntu which is 56GB. So I chose "manual partitioning" and selected the ubuntu partition as /home and began the installation.
Everything seemed to have went well, the window suddenly closed and then nothing happened. I waited for 15mins and still nothing happened. I decided to restart and see what happened, but I discovered that I couldn't boot into windows anymore. It said something about intel boot manager cannot find filesystem. So I decided to boot back from the usb and see if I can reinstall ubuntu, I came to the partitioning part and all the drives were gone, I couldn't see anything, it was blank.
My mum has a computer that has a dual boot with Windows XP and Ubuntu 10.10. Well Ubuntu will not boot anymore, i just get a bunch of CLI output mentioning missing stuff. But she has really important data that she needs which is on the ubuntu partition. I have tried using Ubuntu & Knoppix live CD's the mount the partition and copy the data to her external HDD. On Ubuntu it couldn't mount, it just kept trying and trying forever. On Knoppix it just gave me a heap of CLI output that I have no clue what it means. How can I save all her data? Is there a program that can sav the data, or what is the best way?
1 I have XP installed on HDD1 (SATA 200 Gb master). Now I installed Cetos 5.5 (use 4.1 Gb DVD1) on the second drive, HDD2 (Seagate STA 40 Gb slave.) I didnt fund the option for selecting boot location during installation, just selected second drive. I think this is my first mistaking. The Centos can�t boot up after initial installation. I disconnected the HDD1 (XP drive.) Then finished Centos install. � Second mistaking.
2 After that Sentos installed, I reconnected HDD1 but XP is disappeared. The grub.cfg shows about XP as: Title other Rootnoverity (hd1,0) Chainloader +1
3 For finding XP I disconnected HDD2 (Sentos), but XP can�t be started. This message is shown up:
Just wait 5 seconds for normal startup! Boot: could not find kernel image:vmlinuz
4 I think that stuff was written by grub. I decided to get rid of them then reinstall all. I tried to deleted and create new partition, format c:, fixmbr, and fixboot, then install XP on c:. But above message still shows up when boot machine. I have to use XP install cd to start Windows XP.
I have successfully installed the Nvidia driver on my FC13 system that is using an Nvidia NV44 (Ge 6200) card. It seems to be working as I see the nvidia driver when I do a lsmod | grep nvidia and the glxgears program works as well as the nvidia-settings program.Basically, I did the following:
I installed the nvidia driver from the official repository for openSUSE 11.3 and now everything works perfectly, except i get a verbose splash screen after the grub menu.It has worked after i upgraded from 11.2. In my menu.lst it already says splash=silent.If you want more information, please ask, because i don't know where to look or what to show you (i'm fairly new to linux in general).
I had been dual-booting Ubuntu and Windows 7. Today I upgraded to Ubuntu 10.04 and now Grub still has a Windows 7 boot option, but when selected it goes to a blank screen and does not boot Windows 7 as it would before.
I just replaced my RAM, and searched for the best way to do a memory test in Ubuntu. I ran across this page:
Turn On or Restart the system Hold down Shift to bring up the GRUB menu. Use the arrow keys to move to the entry labeled Ubuntu, memtest86+ Press Enter. The test will run automatically, and continue until you end it by pressing the Escape key Allow the test to run for at least one full pass
So I did exactly that. The GRUB menu appeared, but I had no keyboard control, and thus couldn't select anything. I've tried rebooting several times with different keyboards, and they all show 3 green lights at the very beginning of boot, but become unavailable by the time GRUB appears.
So I booted to a Live CD and the keyboard worked just fine inside that session. But it's still gone during boot. When I'm booting without a CD in the drive (booting to the internal HD as usual), it goes straight to the GRUB list, with no keyboard control, and I'm stuck indefinitely.
how to either bypass this stuck GRUB screen, or somehow restore normal keyboard functionality during early boot?
using onboard windows disk management i have made 75gb unallocated to add to the aforementioned ntfs data partition. but, after resizing extended partition, will i need to fix grub even though i will be adding the unallocated space to a storage partition and not the ubuntu boot partition?
My ubuntu(10.10) installation takes a relatively longer time (90 seconds) to boot. I think part of the problem might be related to an error message during boot related to usb drivers. Code: [2.717076] usb 4-1: new low speed USB device using ohci_hcd and address 2 [3.244051] usb 4-2: new full speed USB device using ohci_hcd and address 3 [12.029046] /build/buildd/linux-2.6.35/drivers/hid/usbhid/hid-core.c: usb_submit_urb(ctrl) failed I have attached the relevant part of dmesg output also.
