Ubuntu Installation :: Can't Boot - Get To Data From Cd / Usb Boot?
Jan 10, 2011
I have dual boot windows 7 and ubuntu 10.04. I had never booted to windows until yesterday by accident, and it did a massive update and hosed my ubuntu so it wouldn't boot. I have data that I'd like to get from my ubuntu partition before a reinstall. To make matters worse, I tried a grub change to try to fix the boot sector problems, and now it won't boot to windows either. It boots directly into the grub prompt. My question is, can I boot from a cd/usb and then access my hard disk ubuntu data so I can back it up over a network before I reinstall ubuntu?

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!

I installed 11.04 after Windows 7. when the GRUB boot menu starts up there is an option for Win 7 boot but it will not boot windows. When that option is selected the screen changes colour for 2 seconds and then reverts to the GRUB menu. Ubuntu boots fine.I downloaded the Boot Info Script and ran it, the results are

I am installing a custom 8.04 live disk (basically, a mirror of my whole system with user data intact, sans all non-OS files) from a USB key with remastersys for the .iso creation, and UNetbootin for the bootable USB on a brand new 120GB PATA WD HDD. Both do nicely so far, so I have a working livedisk to use until I need to install Ubuntu to the drive.
I had a pure linux box, but I need to add XP with dual booting now- I have to use Autodesk Inventor 2010 software for my college class on my laptop, so I don't drive 30 miles to use the 1 computer lab equipped with that software. I'm not new to Linux, but I am new to more in-depth partitioning. I've taken the lead and looked into things- read this good guide, among others:
HTML Code:
http://www.psychocats.net/ubuntu/partitioning and noticed that there is a way to more deftly use partitions so that personal files can be shared access and write between Windows and Linux partitions- with this:
HTML Code:
http://www.fs-driver.org/ Ubuntu is still my main OS, but being able to access all my media/data files between the 2 systems would be nice. Problem is, until now, I've put everything on a single partition because I didn't know better. Now I do, but am a bit confused with all the guides as to what's most efficient, especially in my case where full RAM speed is crucial to running a single program.
Here's what I know I need to do: 1. The Windows XP install I know needs from 20-30GB for Inventor 2010 LT to work well. I don't need anything else in XP spacewise- it's just being added for Inventor. 2. I'd like to create a separate /home partition for Ubuntu this time to save my user data, making future upgrades much more painless (I will be getting Lucid soon). How that works when upgrading, though, I don't know yet..
3. I'd like both OSes to share all my personal files (docs, pics, music, Inventor design files) if it is an efficient choice that works without problems.
4. Finally, because 2GB is minimum for Inventor to run decently, I need to maximize the speed of my RAM for it- from my reading, these so-called "swap" partitions can somehow be added for buffering this- people seem to sugguest the swap be half the size of the RAM for fastest speed, and some say add separate /usr or other partitions. I'm not clear on what would be most efficient for me.
I have limited HDD space- because of my laptop's BIOS, this single 120GB drive is the biggest I can get on my laptop, so efficient partitioning would make a huge difference for me. Before this, a 60GB HDD was in this. I'd like to see some added space for my data storage, but still keep things as fast as possible for Inventor when I use it, and Ubuntu.

I'd like the final layout to have a Windows partition (will start out as XP and will become Win7 when I can afford yet another copy), a partition for Ubuntu, and a shared Data partition that I can use for all my files between both OSs. I think this should be fairly straight forward with Linux on a Primary partition with / and swap. Only thing is, from what I've read (and yes I know this is a bit old school) it might be a good idea to put in a /Home partition so that I can reinstall new upgrades and maintain settings. But I don't want to max out my 4 primary partitions so I can use a 4th partition as a kind of sandbox for OS testing without using VirtualBox all the time.
This leaves me in need of some advice, I've never used Fdisk and I was planning on just using the Ubuntu installer to do all of this, but I don't know if I can create /Home as a logical partition in the main Ubuntu partition and still have the benefit of being able to reformat /root without losing /Home. I might have just confused myself, because no matter how many guides and How Tos I read I still don't really get extended partitions, I understand logical vs. primary but extended is...confusing. I need the Ubuntu partition to be bootable, so it needs to be a primary partition...I think. Unless I can have: /boot, /, swap, and /Home...
Also, if Ubuntu can read NTFS, and Win7 can read Ext3, what should a do with /Data? Or should I just go with FAT32 and be done with it. (It's a big HDD btw, 640 GB, so /Data will be fairly large)

I am trying to install ubuntu 10.04 on windows7.windows 7 was already installed.I ollowed these steps to install ubuntu 10.04.1)First i made some freespace in hard disk to install ubuntu using windows7 default options(By shrinking).2)I used USB drive to install ubuntu.I made it bootable using unetbootin.3)I followed normal steps install(language,area,keyboard,using manual partition i installed ubuntu in free space,etc).4)I got boot menu when it restarted.PROBLEM isAs long i use only ubuntu (boot into ubuntu --shutdown--boot into ubuntu --shutdown) it works well.
If once i boot into windows 7 and restart the system i am loosing boot menu options.The following error i am getting"no module name found Aborted.Press any key to exit".If i press any key,I guess its trying boot using internet and lastly it says Operating system not found and hangs.

I've recently tried to do a full install to a USB stick using a 10.04 cd.
2 things happen as I boot:
1. if Hdds are attached, boot hangs on "checking dmi pool data..."
2. if hdds not attached, "hdd error" scrolls across screen
boots normally w/o the usb stick. I've set up my partitions on usb stick as
1: fat32 2gb <<windows/storage
2: fat32 1.5gb << future persistent install
3: ext4 4gb << hoped-for full install
1 is the first partition so windows finds it nicely. Before install, i unplugged my hdds so that grub wouldn't get confused. I told the installer to put the full install on sda3 with no swap space. I checked (advanced button on summary page) that bootloader is being installed to the usb on dev/sda (sda since no other drives attached). This should put it in the MBR (i think?)
Seems like I pressed all the right buttons huh? Is there a way to diagnose grub and see what's wrong? is there a reason grub may not initialize properly from a usb drive?

I had Fedora11 (default layout) running on a separate hard drive (winXP on the other drive). After the FC drive failure I replaced the drive and did a fresh install again. This time I tried a custom layout to keep the /home on a separate partition. The installation went without a hitch, but on first boot the system hangs with "Verifying DMI Pool Data......"
XP boots fine though. Looks like grub doesn't get loaded. I can boot with the installation cd and get into recovery mode, everything seems fine on the fedora disk. Fdisk result:

I downloaded the Fedora live dvd iso file, burned it to a dvd. I was wondering if I forgot to do something or did I do something wrong. When I try to install from the dvd I get this error message, isoLinux: Disk error 80 , AX = 42A7 , drive 9F Boot Failed: press key to retry When I press a key to retry I get the same error. I also tried to install virtual pc and get not boot disk found.

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.

I'm trying to install F11 on a machine that was running well under F10 just a few hours ago. I made some changes to the disk configuration, involving the addition of a dmraid-controllable fakeRAID card (SiL 3124 I think) and creating a RAID 0 array out of the two drives connected to the motherboard itself (Intel ICH7R). Otherwise the machine's configuration is identical to the way it was when running F10. My problem is thus: when I boot from the installation DVD (64-bit), the boot process doesn't make it even to anaconda. Here is the error I get, right after md devices are autoconfigured:

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.

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 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".

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

I recently got a netbook and setup as dual boot between win7 starter and 9.10 (64bit). Win 7 starter is not impressive so i want to nuke it and give the space all to my /USR partion. I am comfortable working with Gparted and assume that i can launch using my gparted live usb and delete the windows partion and then resize the /usr partion.
what changes do i need to make w/ Grub2? I would prefer not to see the Grub menu at all and have it load right the main kernel if possible. Also, if this is possible is there a way to get to the Grub menu during boot should i need to select a different kernel?

I have just installed Ubuntu 10.4 x64 onto a machine with Vista Ultimate x64. When I boot the machine, the Windows option comes up in the GRUB menu. However, when I attempt to boot Windows, I receive the following error: No such device: de80ab9f80ab7d21. error: No such partition. Press any key to continue...
I looked around and found a similar issue at [URL] However, before trying to fix the issue by guesswork or via solutions that worked for a similar, though not necessarily identical problem. I've run the boot info script (see output below) mentioned several places on this site as a valuable input for boot problem tracking. how to get Windows to boot on my computer?

Installed ubuntu 10.4 over previous ubuntu on Intel 945G. After installation and reboot the system does not boot: "no bootable device - insert boot disk and press any key".
Installation was done from USB-stick, prepared by UNETBOOTin. I have two HD's, one used for system + storage, another one just for storage. I manually deleted previous system partitions of previous ubuntu install in system HD. The system HD had about 1/3 of free and unallocated space for system partitions, which ubuntu installer created during the installation.
I tried to reinstall grub from bootable USB-stick and it succeeded but it did not help. The system is still not bootable.
I have used ubuntu for years and never happened something like this. Am I missing something or is ubuntu missing something???
HW failure is ofcourse possible but I am quite skeptical about it because Live ubuntu from USB-stick works well.

I'm trying to install Ubuntu on a computer with Vista SP2, my BIOS supports booting from a USB drive. Ive used unetbootin and Universal USB installer to setup the ISO on the drive, as well as trying Ubuntu version 10.04 and 9.10. The problem is that during the boot it stops at a line reading "SYSLINUX 3.86 2010-04-01 CBIOS Copyright ...", no error messages, it doesn't appear to be frozen as there is a blinking cursor under this line. The boot performs normally up to this point, it happens when, during a normal boot to vista, it says "boot from CD/DVD" then loads windows.It shouldn't be a hardware issue, the computer is pretty new, and I had an older version of Ubuntu install on it temporarily.

I had a a problem booting last night when my laptop battery came loose and caused a crash during boot.It ceased loading a daemon and I turned it off with the power switch, then I received the boot error,then i checked the linuxdrives directory and it was corrupt,I then, out of ignorance, ran wubi from within windows XP and said unistall believing that it would reinstall and fix itself.Thus you can see my green behaviour.I have been searching the threads and have tried many things but have had no success, I will suffer a great loss if I lose that load of Ubuntu as I have allot of work stored there, and in my Thunderbird accounts.

I have a Computer, It came with Windows 7 64bit on it. I installed Ubuntu through WUBI. I used the Windows Disk Management program to resize my HDD. I shrunk the main drive and created a 20 gig free space. I installed WindowsXP on this 20g space. I had to change from AHCI to ATA. I started my new XP installation. As I should have expected my the screen that let me pick between Windows 7 and Ubuntu was gone, and it just said XP. Well thats cool. I get in XP use bcdeasy and use the install Win7 to mbr. So I restarted. Great I now I have Ubuntu and Win7... but no XP. So i think, okay, ill boot into Ubuntu, use the update grub command and XP will be there, so i do it and restart. No XP, So i try to boot into Win7 and see if i can do something in there.. No luck it says it can't boot and takes me to a startup recovery thing. Which, as Windows recovery things tend to do, doesn't find anything wrong. So I have Ubuntu now, which is great, but I do need Windows.

I have searched and read threads about the Bitlocker, grub and TPM issues that might show up, but I can't draw any conclusions as some information contradict each other. To make sure I don't screw up my pc as thought I need to make a new post.
At work I'm supposed to run Windows 7 and encrypt the win-partition with Bitlocker. I have installed Windows, turned on the encryption and it ties into the TPM. But as I am moving over to the *nix department I want to run Ubuntu as dual boot to check everything rusn fine with all the systems I need. Before I installed Windows I partioned the disk:
1,5 GB for system/bitlocker requirement
147 GB for Windows, C:
85 GB which is empty where I intend to install Ubuntu (not formated yet)
I boot into Windows with my bitlocker/TPM key on an USB-stick. Without the usb-stick the pc won't boot. Now, before I try to install Ubuntu I want to make sure to do it the right so I don't mess up the Windows installation or won't be able to boot the pc at all.
There seem to be several "schools" to this. Some suggest I should have installed Ubuntu first, then Windows and then encrypt. Some say, no worries just fire away and install since you are not planning to read the windows-partition from Ubuntu. Or an alternative, install but make sure to deactive the encryption during installation. Some say, install but make sure grub is installed in (multiple choices) location.
