Ubuntu Installation :: Updated To 11.04 - Lost Dual-boot

May 2, 2011

Hey, yesterday I decided to update from 10.10 to 11.04.

I was using Windows Vista in dual-boot with Ubuntu but after updating Ubuntu to 11.04 I lost my dual-boot menu. It worked without problems before update. Now it starts automatically to Ubuntu log in screen.

I've tried so far:

1. Updating GRUB via terminal
2. Looked at my menu entries

grep menuentry /boot/grub/grub.cfg
menuentry 'Ubuntu, Linux-ydin 2.6.38-8-generic' --class ubuntu --class gnu-linux --class gnu --class os {

Ubuntu Installation :: Lost Dual Boot With 10.04 And Windows 7

Apr 6, 2011

How can I get my dual boot working again? I had a dual boot with Ubuntu 10.04 and windows 7. It was all well tweaked but I was annoyed with the ugly boot menue with old kernells so I decided to install BURG loader and remove some of the old kernells. So I did and after that I have not been able to reach my Ubuntu boot.

After multiple attempt to restore the old kernells and reinstall grub (through a USB live stick) i couldnt log in to either system (following the steps in this support thread [URL] Finally i mamanged to get my windows 7 working but my boot menue only shows memtest and windows 7 (not Ubuntu). I am affraid to tamper around to much and having a non funtional lap-top in the end. My lap-top still "miss" 40 GB that was set aside for the Ubuntu boot.

Ubuntu Installation :: 11.04 Lost In Dual Boot After Updating Win 7

May 3, 2011

I was using dual boot (windows 7 and ubuntu 10.10) and it was going well. Couple of days ago I updated to Ubuntu 11.04 and everything was OK. Yesterday I cought some virus in windows, installed Microsoft security essentials which asked to update Windows. After update, dual boot is gone. It boots to windows directly with no option to choose between OS.

Fedora Installation :: Lost - To Ubuntu In A Dual Boot Mess

Feb 14, 2009

I'm trying to dual boot Fedora 10 and Ubuntu 8.10. I have installed Ubuntu first than Fedora (with GRUB installed on it's partition) but Ubuntu's GRUB got messed up. I reinstalled Ubuntu and now Ubuntu works fine but I cannot boot my Fedora. I have set "/fedora" as a mount point for the fc10 install and I can see that from Ubuntu but I can not boot into it. I no longer have any idea where to search for some way of getting it to work without reinstalling ....

Ubuntu :: Lost Data During Dual Boot Installation With Backtrack + 10.04 Netbook?

Dec 28, 2010

Generally I am used to installations of dual boot on different partitions(the traditional method) any windows OS with any ubuntu OS.I tried that with backtrack 4 and Ubuntu 10.04 netbook edition! I had previously installed ubuntu 10.04 and then had an extra partition that had data in it.Went ahead to boot with the backtrack 4 disk BUT it did not give me an option for installing them side-by side so i did it manually by editing the partition with the partitioner! I had 2 swamp spaces one i which was initially there for Ubuntu and the other i created! Then simply formated ine partition with EXT3 and mountpoint of / which made two of them!after installation, the grub shows that there is another OS but when it does not load!

Ubuntu :: Installed Dual Boot Fedora And Lost Kubuntu

Sep 19, 2009

I had Kubuntu 8.10 with KDE 4.0 interface and i decided to try out fedora to see if i liked it and wanted to eventually switch. i've done so many dual boot systems with Kubuntu and not had any problems that i decided not to back up my system this time before running the installation. after running the installation and shrinking my hard drive (200 gb) by 80 gigs, i rebooted to find that Kubuntu was no longer bootable. the first time i booted into fedora, disk utility popped up with a message that said "1 or more hard drives is failing". i ran the test that it recommended and found no problems. then i ran the longer test and still found no problems. i've rebooted a few times and have not been able to see Kubuntu in the boot loader options. if you need any more information i will be happy to provide it. my question, obviously, is how can i retrieve my Kubuntu partition. it is still there but is not bootable.

Ubuntu :: Updated - And Lost ALL Internet ?

Jun 1, 2011

Updated to the latest version several weeks back. Everything loaded fine and system works fine.....except for the internet (wireless AND wired).

I'm still real new at Linux so I just stopped and switched back over to Windows (dual-boot) out of frustration. Figured I'd finally tackle my problem today. Internet and everything worked perfectly before upgrade and now......NOTHING. I hooked laptop (computer running Linux) up to hard line on main computer.....still no internet.

Ubuntu Installation :: Updated To 10.04 And Can't Boot Vista

May 9, 2010

I've got a dual boot system with both Vista and Ubuntu. After upgrading to 10.04 my Vista doesn't load anymore. I select it in the Grub menu and the computer just hangs.

Are there any known fixes for this? Where do I start? I'm an Ubuntu novice, but I'm an able computer fixer.

Ubuntu Installation :: Cannot Boot Into Updated Kernel ?

Jul 8, 2010

I recently updated the kernel of lucid from 2.6.32-22 to the ""-23 release through update manager. Now whenever i try to boot the new kernel from GRUB the screen goes black and the computer stops responding with the caps lock and scroll lock lights flashing on the keyboard.

I can still boot into ""-22 fine and keep using ubuntu.

My first thought that the problem was the newer kernel itself so I tried to update to 2.6.33-5 from [url]but the same boot problem exists within this one also.

Because it goes straight into the black screen after GRUB I have no way of telling what has happened without error messages. Would this appear in any log files and if so which ones?

Ubuntu Installation :: Updated Kernel Will Not Boot ?

Nov 28, 2010

I recently upgraded Linux kernel headers for version 2.6.35 on x86/x86_64 from 2.6.35-22 to 2.6.35-23. and my system will not reboot to the upgraded kernel. To reboot I have to force shutdown my Toshiba L-450 laptop and the restart. This brings me to the GRUB screen were I can choose to use the previous 2.6.35-22. Normally do not see the GRUB screen as I am only running Ubuntu 10.10 64 bit on this computer. I have tried reinstalling linux-headers-2.6.35-23 and linux-headers-2.6.35-23-generic and got the same result.

Ubuntu Installation :: Grub Menu Lost After Dual Booting With Natty?

May 16, 2011

i have lucid lnyx installed as my main system and added natty on a seperate drive. after installing, the new grub detected lynx & i was able to boot into each without any problem. after doing some tweaking on natty (changed run level), it didn't boot properly so i reverted to the old config via rescue disk. after rebooting, the old grub menu didn't show & it loaded lynx automatically.

i tried the suggestion from another post changed the hidden menu and updated grub but it didn't detect natty (below).

Ubuntu Multimedia :: Lost All Sound On Flash After Firefox Updated - Or Shortly Thereafter

Aug 7, 2010

lost all sound on flash after firefox updated (or shortly thereafter)

in other words videos and the like are silent (which is a kind of a blessing, really).

10.04lts 32bit
firefox 3.6.8 - (for ubuntu - canonical 1.0)
flash 1.0.10 (tried r&r already)
external usb sound card, desktop system

sound works great everywhere else, including mp3's on web through firefox. i searched the forum, of course, but didn't find anything that seemed relevant or up-to-date.

Ubuntu Installation :: Nvidia Booting - Automatically Boot To The Gdm/desktop After Updated Gpu Driver?

Oct 11, 2010

Hey everyone I'm pretty new to ubuntu/linux so please bear with me . I recently installed 10.10 on my new htpc. The initial install went great, until I went to install the updated driver for my graphics card. What I did was I downloaded the driver off of nvidia. Then I did these steps:

1. ctrl-alt-f1

2. logged in

3. sudo services gdm stop

4. I then located the driver package that I downloaded and ran it, it seemed to install fine (except for an error about some install script? but it let me proceed)

5. sudo services gdm start

It went to the gdm/ubuntu desktop. However I then connected it via HDMI, and the resolution was way off (top bar was not even displayed on TV) and I tried many different settings but no luck in fixing it. Next after restarting it did not automatically boot to the gdm/desktop. Instead it stayed at the command line login (the ctrl-alt-f1 screen).

tl;dr : 1. How to make it automatically boot to the gdm/desktop after I updated my gpu driver

2. How to fix the resolution for HDMI from my gpu to my TV. (DVI works fine

Ubuntu Installation :: 10.04 / Win XP SP3 Dual Disk Dual Boot

Jun 5, 2010

I am quite experienced user of Ubuntu desktop / server distributions. Recently my desktop 9.10 disk failed and I decided to reinstall using 10.04. My configuration is a dual disk dual bot system. I have XP Pro SP3 on one disk and Ubuntu 10.04 on second. XP has own, untached MBR ubuntu got Grub 2 installed on the same disk as Ubuntu. Ubuntu disk is booting first in BIOS. Grub 2 detected both system, however I can boot only to Ubuntu. When I am trying to boot XP I got black screen only. Looks like booting is stack in BIOS stage, because crt+alt+del reset system.

I read Ubuntu forum, search Google and did not come with any solutions. My XP MBR is OK. I can boot directly, choosing XP HDD in BIOS as a starting disk. All entries in grub.cfg looks fine to me. I made 3 different clear installations of Ubuntu. Each with the same result. I reinstaled Grub2 with no effect. I wonder if this may be a hardware/Grub 2 compatibility issue. I am using quite old components.My motherboard is Assus P4C800 Delux. I have 5 HDDs 2 CD. Exactly the same configuration was OK with 9.10/XP dual disk dual boot using Grub legacy.

Ubuntu Installation :: Disk Error On /boot With Dual Boot On Dual Disk

Dec 30, 2010

I have a (slightly complicated) dual/multi boot system.

I keep getting boot errors (when choosing ubuntu from the grub2 menu)

Serious errors were found while checking the disk drive for /boot

If I switch off and restart, ubuntu will then start without issue.

My setup is like this ....3 disks, one with 10.10 clean install - so Grub2, separate partitions for /, /boot and /home, one with windows 7, one with windows XP and 10.04 wubi (this is my old disk which I will trash once I'm happy with my upgrade to 10.10 & 7 on separate disks.

I installed 7 and 10.10 with ONLY their disks installed. After both were working, I added all disks and rejigged the grub2 menu (using update-grub and StartUp-Manager).

This problem only seems to occur if my previous boot was not 10.10 ( I will investigate this further). It's as if something (grub2 ?, the bios ?) is remembering part of the previous boot and not using the grub2 menu completely.

General :: Grub Boot Loader Installation In Dual Boot Machine After Windows 7 Installation?

Mar 23, 2010

I had a dual boot machine with fedora 12 and windows vista and I could use grub boot-loader to switch between two. Few days ago windows got corrupt and I have to reinstall it. I put windows 7 now and as usual it erased grub. So to reinstall I put the fedora 12 installation CD on and followed some usual setup steps. When I got the command line I issued the command "grub-install /dev/sda" (sda not hda because It showed bunch of sda, sda1..) but surprisingly it said grub command not found. I remember doing it before while it worked fine.

Ubuntu Installation :: Pretty Much Lost Trying To Boot From CD?

Aug 2, 2010

As a back story, my Thinkpad had two partitions on it; one with Windows Vista and one with Windows 7. But it can't find the boot files, and thus isn't starting up (I'm getting a remove media or other devices error). So I'm just trying to get it working by trying to download the Ubuntu ISO on another computer, burning it to a disk and then booting it up on my Thinkpad.

I downloaded the 32-bit ISO of Ubuntu. It's ubuntu-10.04-desktop-i386, and it's 699MB, making me think that nothing is inherently wrong with the file I'm trying to burn. So I use InfraRecorder to burn it to an empty CD-R disk with 702MB of free space. (I tried using a DVD-R earlier, but switched over to CD-Rs after the DVD gave me the same problems that the CD-R is now giving me.) So I open up IR, find the ISO file, and burn it to the CD. Everything appears to work normally, and the disk pops out once it is done.

Now the Ubuntu website tells me that I can open up the CD-R file and check its contents, but I can't seem to do that, or at least on my computer. I put the disk back in (while running Vista on the computer I burned it on) and nothing happens, although I don't know if something is supposed to happen. I click on the DVD drive whilst in My Computer, and it pops out again (with the disk still in it) and tells me to insert a disk... whatever I think.

So maybe it's just not meant to work when already in Windows, but I put it into my Lenovo, boot from the CD/RW and am getting the same error. The specific error isn't really relevant, but rather the fact that it isn't even booting into Ubuntu. Clarifications: The integrity of the ISO file or the distribution are not the cause. I downloaded Linux Mint and encountered the same problem.

The computer burning the disk is not the problem. I used InfraRecorder and other burning software on two different computers, and both got to 100% and ejected the disk. The problem is that the disk is full, but not doing anything on either of the two computers I'm using to burn, and isn't booting up on my Thinkpad.

I had a dual boot windows xp / ubuntu system. I needed to put more disk space on my system so I had the win xp system disk cloned. After doing that my ubuntu installation no longer appears.

The Ubuntu system was and is on a separate hard drive. So I am fairly sure that it is intact.

Is there someway I can restore the boot information?

Ubuntu Installation :: Cannot Get To Boot Up / Show Menu On Dual Boot With Vista Initially

Jan 18, 2010

Have just installed 9.10, again, many failed attempts previously.Cannot get to boot up and show menu on dual boot with Vista initially,However when I delete the grubenv file the system boots ok and works fine.But does not show the grub menu to choose boot up choices.Got the information to delete the file on some posts elsewhere about booting problem, and tried a longshot and got into Ubuntu for the first time from trying to install now for 3 months!The problem is the file grubenv is created each time so on subsequent boot ups the sytem fails to boot again.The Grub version is 1.97 beta 4, most up to date for Karmic I think, I have seen a version 1.98 but dont think its for Karmic?

Is there a way to modify the grub.cfg file to stop this problem ( all posts say dont touch this file??Or install a script to delete the grubenv file on shutdown as a workaround for me, (I have no idea how to do this whatsoever, I'm not familiar with linux at all)I did read that this problem was fixed/patched in Grub version 2, but dosn't seem.so on my system afetr I updated it when I got into Ubuntu.I couldnt find the patch or fix, I got the information I am on about from this post:URL...It seems to say it was fixed or patched by Colin Watson reading through, but I don't really understand whats being said or how to get the patch on my system if indeed there is one?Sorry for being a bit thick about all this, its a bit beyond my brain now, hope somebody can help out as I have enjoyed my brief bit of fun in Ubuntu.

Ubuntu Installation :: Xp And - Netbook Dual Boot - Error - Windows Boot Failed

Jul 8, 2010

I have a netbook running Windows XP as standard. There is also a recovery partition which came from the factory.

In the past I installed Ubuntu (I think 9.something) from USB key and all worked fine. However my XP became corrupted and I needed to do a repair on it. After this, Ubuntu became removed from the boot select menu.

Since then, Ubuntu has become updated to 10.04, which I now cannot install.

The Live CD tells me there is a "file IO error" and simply stops installation at around 70%.

I did manage to get into Ubuntu from a Live USB using Wubi. However when I chose to install Ubuntu to a Harddrive, the option to "install side by side" was missing.

After reading on the forums, I did a chkdsk /f on Windows and tried again. Now my liveUSB does not show a boot menu!

When I select to boot from USB stick, the screen goes blank with a flashing cursor. Ctrl+alt+dlt reboots.

I'm really lost here! It seems when I fix one problem, another problem arises!

Also when trying to instal Ubuntu within Windows, the process goes through to 100% and asks me to reboot. When I do so, the option for Ubuntu does show in the boot menu. However when I select it, I get an error "Windows boot failed: file wubildr.mbr and status: 0xc00000f - something is corrupt".

Ubuntu Installation :: Unable To Boot On Dual-boot XP After Recovering Windows Bootloader?

Jul 18, 2010

I have Ubuntu 10.04 LTS and Windows XP installed on my laptop. Usually when booting, I get the GRUB 2 menu and I can boot into either Ubuntu or XP.I was playing around with EasyBCD, then after trying to remove it I was unable to boot into Windows, I used a Windows 2000 CD recovery console to fix the MBR (using: fixboot and fixmbr).Now Windows starts up when I power on, but I don't get the grub menu anymore with an Ubuntu option. If I boot from the Ubuntu Live CD and try to mount my Ubuntu partition (/dev/sda5) I get this error:

mount: wrong fs type, bad option, bad superblock on /dev/sda5,
missing codepage or helper program, or other error
In some cases useful info is found in syslog - try
