Ubuntu Installation :: Cannot Boot After Install (11.04, 10.10), Dual Boot?
Jul 9, 2011
I'm having a frustrating time trying to install Ubuntu as a dual boot with Windows 7 on a new Acer Aspire 5750.The initial install proceeded without incident until an error along the lines of "Cannot install GRUB to /dev/sda".I continued without installing GRUB, and attempted to install GRUB from the live CD:Code:sudo mount /dev/sda5 /mntsudo grub-setup -d /mnt/boot/grub /dev/sdaThis installed GRUB, but only linking to my Windows 7 partition (sda2).

I am trying to install Ubuntu on a machine that already has Windows 7 on one partition. Obviously I intend to install it on the other free partition. So I downloaded the iso burnt it onto the disk and pop in the disk and the boot the machine. The installation screen comes up I selected the first option (Try Ubuntu without installation), I just see a prompt after a few seconds and then the screen goes blank and nothing happens. Unable to detect a signal, The monitor goes into standby. The same thing happens if I use "install Ubuntu" option as well. I downloaded minimal install version Ubuntu and tried to install with that. since its old school installation, the installation completed without any errors, but when I restart the grub come up and when I select to boot into Ubuntu, I see the same behavior i.e. the screen goes blank and never boots to anything. This is a machine on which I was using 10.4 until yesterday.

I want to install ubuntu with dual boot.
I already installed the xp.
I followed this step.
Code:
Hard disk partition:
Selected first option "install them side by side, choosing between them at each startup." to get dual boot.
All went fine until when i click the install button(setp 7 of 7).
Installation window appeared and showed 1% in the progress bar.
Then one blank screen appeared and go to Ubuntu Desktop.

I have a PC with 3 hard disks, one IDE (30GB) plus two Sata (80 & 180 GB). The IDE is the disk master. Previously I had Ubuntu on the IDE disk, the smaller SATA for Windows XP and the larger SATA for all data. I recently decided to do a clean Windows install and thought that at the same time I'd swap the two OS disks. After I successfully installed the two systems (Ubuntu is Grub 2) I don't get any options presented at boot up. If I boot from hard disk and choose the IDE disk Windows books immediately. If I try to change the disk boot order in the BIOS to choose the Ubuntu disk, nothing happens. Any idea how to get my dual boot back?

I want to install ubuntu as a dual boot OS (running Windows 7 at the moment). What would be the best way for me to do this? Would it be the windows installer option Ubuntu has?

it started with rooting my Motorola Droid. I got quite interested in the whole rooting/linux "world". The only problem is, my hands move A LOT faster than my brain does. I'm an "educated novice" at best when it comes to all of this and still learning slowly, but surely. I followed an online tutorial and before I realized quite what i'd done, I had dual installed Ubuntu linux 10.10 on my laptop. ISO'd this, partitioned that and realized....i'm in way over my head. Then I started researching how to just go back in time and get my "safe" windows vista back until I'm ready to make the switch to linux and just ended up getting more confused.
How do I actually BOOT into Windows on a dual boot computer that I apparently just created? How, if need be, do I undo everything I just did in the past few hours and careless tinkering? If I decide to stay with Linux, how do I get my damn wireless router to recognize?

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 have recently installed Ubuntu 10.04 on a Compaq Presario V3000.
To prepare the install, I freed about 15 GB of space, booted from an USB. I chose "use largest continous free space" when it got to that point and then proceeded with the rest.
Now when I choose vista it will not load properly, here's what happens:
1.Windows says loading windows files.
2.After a while, I have to choose a language.
3.Windows looks for operating systems to repair.
If I choose not to, it will take me to a menu where I can choose to fix boot problems, command line, etc...
Linux is running very well, vista is the problem here, I have a recovery disk*, but I wanted to ask you guys if that is the correct move. I really need to keep windows to run some windows only apps.
*This disk was burnt on another computer, an HP from a friend who has the same vista edition. Will this work? This computer's burner is broken..
This is actually something for my gf, she has an account on my computer(only ubuntu on it) and uses it often (Mendley, Zotero, and sciency things in general). She loved it and asked me to install a dual boot with her win system. She use SPSS for whatever kind of statistical analysis it does and she likes ms office better then open office, and I would like to leave her with the choice....

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 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?

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.

I'm trying to dual boot Win7 and Ubuntu WITHOUT using Grub. This is to support Bitlocker encryption.
I followed this guide, and now when I select Ubuntu I get a Grub> prompt and no ubuntu.
I feel like I'm halfway there, I just need to get Grub to load correctly or something.

After installing karmic with Grub2 I am unable to boot into Archlinux partition. Grub2 has removed the last line of the Archlinux boot stanza! It used to read:-
[Code]....
Following the Grub2 tutorials I have tried editing /etc/grub.d/40_custom as follows:-
[Code]....
But no luck. Only way into Archlinux is to get into the edit shell and manually add the missing line and remove other stuff not needed. I have spent hours trying to resolve this issue and I am fairly p----d off

I need to re-install ubuntu but I also have windows on the same computer(GRUB). Can I just boot from cd? Is there and option in the live cd for reinstalls or do I have to destroy the partition?

I FINALLY convinced my wife to try Ubuntu on her laptop. We selected Install 10.4 side-by-side with XP. The grub menu shows up, but Windows is not listed. She's happy with Ubuntu so far, but I'd like to know why I can't use XP anymore. btw, I actually made the mistake of using the import accounts option, which filled up the new partition and made Ubuntu unbootable. I deleted some things from the command prompt, and it's running fine now.HP Pavilion1.5 GHz512MB Ram

I am running Windows 7 starter on my Samsung N150 Netbook. I have successfully installed Ubuntu on the 4 GB flash drive, and I have been running it for several weeks in the "try mode" without any problems. Now I decided to permanently install Ubuntu netbook edition on my computer from a flash drive. I am following this guide [url] and ran into a big problem on step #5 of the guide and step #4 of the installation. I am not getting the option of installing them side by side, choose between them each startup! Which is what I want to do... I am only getting the option of erase and use entire drive, and specify partitions manually. My goal is to keep Windows 7 on my netbook, and have an option of dual booting into either operating system.

No option to install alongside another OS. I have Win7 Starter on this new netbook and need to install Ubuntu 10.10 netbook addition. Disk Management shows 4 partitions, one is C:, one is D:, and two I've never seen before they're so small. Is it safe to delete these or do they have a purpose for the current Win OS? I would gladly install the 10.10 to my D: drive which seems to be SDA2, the 131GB partition. What's the right sequence of partitioning and formatting to give Ubuntu the full install it needs manually? And what needs to be taken care of for a Swap drive?

I want to reinstall Ubuntu on top of the existing Ubuntu installation on this machine so that I have a fresh install of Ubuntu.I don't mind losing all my data on my Ubuntu partition, but I need to keep all the data currently available on my Windows partition.

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 am ready to reclaim the disk space that is currently being used by XP in my dualboot scenario. Per the Gparted scan below, my hard drive is currently being sequenced as sda1 (NTFS data only, which I mounted in Ubuntu and write my working documents to), sda2 (XP operating system/boot drive). Ubuntu is on sda3, with home on sda4. I'm currently running 9.10.
I would like to eliminate the contents of sda2, and migrate sda1 contents to ext4. Question is, what are the best steps. I have good backups of everything, and sync my NTFS data to a NAS.
My grub.cfg looks as follows (am running 1.97)

When I first installed Ubuntu as a dual-boot (about 18 months ago), I had problems booting to XP, which were eventually solved for me in this thread, which set Windows to boot Ubuntu, rather than the other way round.
I've just had to do a fresh install of Maverick, following a major problem, and I'm back to being unable to boot XP. The error is different from before and I don't want to start guessing at what to do about it and screwing things up still further.
The GRUB menu lists Ubuntu first, then Windows XP. If I choose XP, it takes me to my previous boot menu, with Windows as the first option. However, selecting this gives me
Code:
Windows could not start because the following file is missing or corrupt:
<Windows root>system32
toskml.exe
Please re-install a copy of the above file. Windows and Ubuntu are on separate hard drives. XP was fine until I re-installed Ubuntu.

recently sent up another computer as follows:Two sata drives. Windows 7 was installed on the first drive(sda)and booted successfully. This drive was disconnected ( I have had some installs where Unbuntu wipes out the existing C drive eventhough I am installing to D) and Ubuntu was installed to the second drive (sdb). At one point I had to rebuild the grup on the Ubuntu drive and was careful to make it installed on the Ubuntu drive. To my surprise when the PC booted up I saw the Grub menu with a menu entry for Windows. The Windows drive was always the primary drive before the Ubuntu install. I was planning on the Windows drive being the boot drive and using a boot manager to determine where to go from there. If I utilize the BIOS boot option (F12) I can boot each drive individually. I cannot in BIOS set a particular drive to boot - just a hard drive. Everything is working I am just curious why the primary drive does not boot first. IN BIOS the Windows drive is a primary SATA with a lower number that the Ubuntu drive which is listed as a secondary drive.

I can only use the Live CD to operate Ubuntu. After typing in the command sudo fdisk -l, I get the following?
Disk /dev/sda: 320.1 GB, 320072933376 bytes
255 heads, 63 sectors/track, 38913 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

And when I boot without the Live CD, I get the following message in the GNU GRUB Version 1.98-1ubuntu7 window page.

So we install Windows 7 home premium. Then in goes the Ubuntu Disk. Ubuntu seems to think that the windows 7 partition is one big lump of unallocated space. Tried multiple re-installs of Windows 7, all concluding the same. A bit of googling told me that it has something to do with partition tables or something. I even tried to use Gdisk to delete Gpt from the windows disk, which - as I have absolutely no idea what any of it means, - resulted in me screwing up the entire Win7 partition hence win7 not being able to boot anymore.
i've seen on the internet include a lot of technical garble which I don't understand. I've been using Linux for a while, but as far as partitioning and dual booting is concerned, it's always gone smoothly for me up until now

I turn back to openSUSE and install it in my machine (win7 installed first),but i can't boot from win7. openSUSE doesn't boot from win7 (like ubuntu) and i can't see ntfs win7 partition from openSUSE. Why openSUSE is so complicated about dual booting
