Ubuntu Installation :: GRUB2 Bootloader Crashes With Win7 And 10.04 Dual Boot?
May 7, 2010
I have a Dell Studio 14 laptop with Windows 7 64bit preinstalled. The processor is core i5 and the machine has 4GB RAM. I freed 25GB of memory from my Hard disk and tried to install Ubuntu 10.04 (AMD). Everything went fine. I restarted and Logged into Ubuntu. It worked like a charm. Then I restarted to Windows7. This also worked well as expected.
But, when I rebooted again, I got a black screen saying that �No modules found. Press any key to restart�
When I press a key, it says �No operating system found�, probably after checking through a network (it printed lines starting with PXE).
I tried exactly in the same way with Ubuntu 8.04 in my machine, and this worked without any problem. The Bootloader was not corrupted after restarting from Windows. I noticed the problem with Ubuntu 9.10 and 10.04. I feel like a problem regarding the bootloader version. AFAIK, 9.10 and 10.04 is using GRUB2 when 8.04 use the old version of GRUB. Will I have to switch to the legacy GRUB? (I would love to keep using GRUB2). If yes, I would like to know How.
I have a Dell ZINO HD and dual booted fine prior to 10.04. Grubs seems to not identify the Win7 OS partition correctly. According to Disk utility DEV/SDA1 is a DELL utility partition, DEV/SDA2 is the RECOVERY partition, DEV/SDA3 is my Win7 OS partition...and DEV/SDA5 is my Linux partition. Ubuntu boots fine... but with GRUB using SDA2 (HD0,2) for win7 I cannot boot to it... is there a fix?
The following is in my GRUB.CFG file ### BEGIN /etc/grub.d/30_os-prober ### menuentry "Windows 7 (loader) (on /dev/sda2)" {
I just tried to install OpenSUSE 11.3 on sda4 which is approximately the 2nd half of a 1TB drive, with a pre-existing Win7 installation on the 1st half. The installation summary (before it made any changes) told me "The bootloader is installed on a partition that does not lie entirely below 128GB. The system might not boot." Naturally, not keen on having a computer that won't boot, I aborted the installation.
Of course it's not below 128GB -- Windows is there.
Is there a workaround that is straightforward enough for someone who has very limited experience with GNU/Linux and isn't a comp-sci student?
I have a win7/10.10 dual-boot set up, more or less following the lifehacker.com tutorial (I know, I know). I had to reinstall windows, and its taken over the MBR so that only win7 boots now. My shared drive and the ubuntu filesystem are still there, I just can't get to them without a boot cd. So, I tried to follow the tutorials, which all basically say to reinstall grub or grub2. I tried one method, but ubuntu told me that installing grub2 anywhere but the MBR was a bad idea
I had vista installed, then I installed Win7 on a dif. partition. Then I installed Ubuntu 11.4 over the vista partition (formatted first), and now I can't get into Win7. I'm really at a loss. I've tried the Win7 disk, and it doesn't detect the Win7 installation. I've also tried sudo update-grub, and it doesn't seem to detect the win7 install either. I've tried making the Win7 partition bootable using gpart as well. I'd like to dual boot Win7 and Ubuntu, however I need to do that.
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 am getting a new computer with Windows 7 installed. It will contain a second hard disk on which I will install Fedora Linux. I plan to put grub in the /boot partition of that disk,so I won't be able to boot Linux directly to start. I plan to use the Windows 7 bootloader to dual boot, and I understand in principle how this is done. I set up a previous computer which was running Vista this way, using the program Easy BCD which simplified setting up the Vista bootloader. But the Easy BCD website doesn't address the question of what to do with Windows 7.
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.
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 bought a new computer (laptop HP DV6-1375dx) and I want to set a dual boot with win7, like I did with my desktop (clean install) However, my question is, with the new laptop all I have is the rescue disks vs. having the single OEM version. IS that a problem? for the desktop I followed lifehackers article "Dual boot win7 and ubuntu in perfect harmony." no problems at all.
what I am afraid of is formatting the new hard drive and the recovery partition and not being able to use the disks for some reason....am I over-reacting?
I've tried this a couple of times and can't load Ubuntu.Here's the scenerio, I have 3 partitions.
/dev/sda1 = ntfs (Win7) /dev/sda2 = ext4 with the / mount point /dev/sda3 = swap space
I've some tutorials where I need a /boot partition as well and others where I just need the root partition. At the bottom, there is a drop down box for you to select the device for boot loader installation. Those options include /dev/sda, /dev/sda1 (Win7) and /dev/sda2.
I need to do to get the dual boot working? My first thought is to install the boot loader onto /dev/sda but I'm unsure. It keeps booting Win7 and can't get the option to load Ubuntu.
I've installed Ubuntu 10.10 (64bit) next to my Windows 7, in SSD hard drive. I'm able to boot Ubuntu with no problem, but my problem is my Windows. When I try to enter windows 7, all I get is a black screen with one blink char, and from there it does nothing...
I have the option of selecting between win7 and Ubuntu during start up, but when i select Ubuntu it goes to the first 2 lines of command and then restarts again. Windows 7 works fine. This is the second installation of ubuntu on this computer, the first attempt did the same thing (would not boot into ubuntu but win was fine) after i lost power. This time i shut the computer off for a full week while i was on vacation. I have switched between windows and ubuntu a couple of times and had no issue with this installation.

I used to have a win7 hp laptop. I decided to use ubuntu9.10. i installed it to my second drive (d after shrinking of c: drive to 100 gb. After installation of ubuntu, i try to boot win7 from grub screen, it goes to blue screen and restarting, not opening. But when i choose ubuntu, it is working properly. When i try to repair it, the win7 cd does not see any drive, only its x drive (where it boots). how can i start my win7 again. I am working on this 2 days.

Does ANYONE have a stable dual boot Win7 & Ubuntu 10.04 system? I have been trying for WEEKS to get a computer configured for my student lab. I get things going and everything seems to work for a few days. And then for no reason, the next time I reboot, Grub just seems to commit suicide.
Latest example. Win 7 & Ubuntu have been co-existing perfectly fine for about a week. Iow, I do something, then reboot, and the grub menu comes up - I select something and it boots my OS of choice for that session.
But today, I've been putting the last few touches on this computer before I use Clonezilla to copy it to all of the computers in the lab. You know - hard stuff like:
* set the default profile in Windows
* install a printer in both Ubuntu & Windows
* set a background image for the logon screens that have our "don't do anything bad" policy.
how there is nothing in there that should mess w/ grub or the boot loader, right? Yet I reboot the computer, I get to where grub should load - and BARF - I get the Bios splash screen again and the computer reboots on it's own. What the !@(#$&!@#$% is going on that this keeps happening to begin with?
I was trying to dual boot ubuntu on my desktop which has windows 7 already installed on it with raid 0. I have 2 500GB hard drive and when I boot from cd and try to install ubuntu it only detect one of my hard drives and it said I only have 500GB and there is no OS installed on this machine! I look online but I couldn't find any solution!
Current set-up: Athlon 64 2800 2 GB RAM 340 GB on two HDD Ubuntu 10.04 LTS Win XP Pro SP3
After getting the Silver Ghost all set up and purring like a kitten for my daughter, she now informs me she'd rather have Win7 HP instead of Win XP Pro SP3. Ubuntu and Win XP Pro are on separate HDD. Can I do a "clean install" of Win 7 HP on the Windows drive without screwing up GRUB? Or will I need to do the dance described at [URL]. I've had to modify Ubuntu because of conflicts between 10.04 and the Ralink 2780 (?) wireless-n drivers.
I have successfully installed Ubuntu 10.10 on two older computers, one a laptop using wubi, and the other an older Dell 8250 using an install CD with a dual boot on one drive. Now I'm trying to install Ubuntu 10.10 32 bit to my Windows 7 64 machine which has one C: drive with one partition and plenty of free space, with the goal of installing Ubuntu to a logical second partition on an external hard drive attached with a USB connection.
Unfortunately, after I boot from CD and start the install, I can't get past the install screen titled "Preparing to install Ubuntu", on which I have checked "Download updates while installing" and "Install third party software". I have three green checks for the install criteria and am connected to the internet. After I click "Forward", the spinning "busy" mouse icon continues to spin for about 20 minutes (I haven't gone longer than this) but does not progress me to the next screen. I can quit the install by clicking on "Quit".
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?
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 recently installed Ubuntu and thus am now dual booting it with W7 (which was installed first). These are the options I get with Grub:
Ubuntu, Linux 2.6.31-16-generic Ubuntu, Linux 2.6.31-16-generic (recovery mode) Ubuntu, Linux 2.6.31-14-generic Ubuntu, Linux 2.6.31-14-generic (recovery mode) Memory test (memtest86+) Memory test (memtest86+, serial console 115200) Windows 7 (loader) (on /dev/sda1)
I'm not sure if there is something wrong with this; why is there an option for Linux 16 and then for 14? At the moment I'm booting into Ubuntu using Linux 16. I'm a sticker for looks and would prefer reducing it down just to: Windows 7 Ubuntu
I would like to dual boot Ubuntu and Windows 7. I have Ubuntu 9.10 Live CD and Windows 7 Pro Live CD. Ubuntu is installed but Windows 7 isn`t. I have gparted installed. I found the following directions within Ubuntu documentation.
Master Boot Record backup and re-replacement Back-up the existing MBR, install Windows, replace your backup overwriting the Windows boot code: Create an NTFS partition for windows (using fdisk, GPartEd or whatever tool you are familiar with) Backup the MBR e.g. dd if=/dev/sda of=/mbr.bin bs=446 count=1 Install windows Boot into a LiveCD Mount your root partition in the LiveCD Restore the MBR e.g. dd if=/media/sda/mbr.bin of=/dev/sda bs=446 count=1 Restart and Ubuntu will boot Setup grub to boot windows
I don't want to backup the MBR and restore as listed. I would rather use the Ubuntu Live CD to reinstall the GRUB. How do I overwrite the MBR? Do I use gparted and change the partition? Do I create an NTFS partition as listed above? Or what do I need to otherwise do to boot the Windows 7 Live CD so that it will install?
I'm completely new to Ubuntu, and haven't actually installed it yet, so my questions aren't concerned about how I use it, but rather the problems of installment and more importantly how to get started. The first thing I got a little question for is how to split my HDD into two partitions in order to install Ubuntu, as I will be dual-booting it with Windows 7. The second thing I want to ask about is how big the risk of corrupting my HDD is when installing Ubuntu, and whether I can take some precautions in order to reduce the risk of said thing. The third thing I'm gonna ask about is how to get drivers for my graphics and that alike. And fourth and last: Is it going to make a difference that I'm running it on a laptop?
I installed Fedora13 to dualboot w/ my windows 7. I quickly found out that I don't care for fedora. I was referred to Ubuntu, and put Ubuntu 10.04 on in VirtualBox. Lo and behold, I like Ubuntu a WHOLE lot more! So, I promptly went to Disk Manager (in win7) and deleted the Fedora partitions (told you i'm a noob). Of course that was a poor choice, and I was only able to get my computer to boot again by reinstalling f13. neat.

SO what i was thinking is go back to Disk Manager, delete partitions sda 3,4, & 5 (the linux ones), then reboot from the Ubuntu live disk? But I don't know what the sdb1 partition is?
I haven't done this in a long time, so I probably just need a quick refresher on a few things. I had to revert to Vista as my primary OS for more than a year to do CAD work, but now I finally have the freedom to move back to Ubuntu. I have my Win7 upgrade that I still haven't done (yes, I know I'm late to the party) and I want to update my Ubuntu 9.04 install to 10.10.
If I remember how to do this correctly, I should upgrade Vista to Win7 first, and then install Ubuntu second. I have two separate hard drives, so each OS will go on a separate one. The only issue I had in the past is that the drive with Ubuntu on it must be set as the primary boot device, otherwise GRUB wouldn't load. Is this all correct? I've been out of the Ubuntu loop for quite a while, are there any caveats to this process that I should be aware of?
I have a pretty good grasp on general computer works and I have read alot about the dual boot system and can do it with multiple variations of linux. My problem lies within my laptop, that I want to do a dual boot on (which is my only one with wireless). It is currently running Vista Home Premium-x86 and I would like the upgrade to Windows 7 Proffessional-x64. I have access to it but I have to keep Vista as is in order to keep Windows 7 as an upgrade which will have to be a custom install. This HD is dedicated to Vista and the backup partition as it is already.
I've read just about everywhere that you first have to do Ubuntu install and partition and then Windows, which makes sence, and then change the GRUB. However, I'm unsure about this case.
What would be the best way of going about making the partitioning scheme? I've already backed up everything possible so loosing that info is not the problem. Vista is the problem. My HD is a toshiba 320gbs- 2.5" form factor. My plan was to make 3 partitions. Windows, Ubuntu, and then the back up partion for Windows. I wanted to allocate Windows 150gb, Ubuntu 150gb, and then the other 20gb as back up for Windows.
I wanted to install ubuntu 11.04 alongside win7 on my notebook (with no optical drive). I created 2 primary partitions (one for win7 [ntfs] one for ubuntu [ext4]) and 2 logical partitions (one for swap one for general use for storage[ntfs]) by running ubuntu from my USB Flash disk and using gparted. First, I installed win7 without having any problem, then ubuntu also without having any (apparent) problem (I installed boot loader on MBR: the default setting). After the ubuntu installation is over, I was instructed to restart my computer as usual and win7 started without asking me which OS to boot. When I run ubuntu from my Flash disk and run gparted and selected the boot drive as the partition on which ubuntu was installed, I got the error saying "missing operating system". I suppose GRUB is misconfigured and that is causing the problem because nothing went wrong during the installation processes. How to configure GRUB by running ubuntu from my Flash disk. BTW win7 is working just fine.
I installed ubuntu 11.04 to my Compaq Presario CQ61-402SA (Dual boot with windows 7 Home premium 64-bit, Via a partition) And now I can't get back to my W7! Disk Utility says that it is "unallocated"! It had lot's of important info on it! Sorry for urgency, but it's important I get this OS and files back, intact.
I've already had WinXP SP3 installed on one HDD, so i've installed 10.04 on my spare HDD. When I try to boot to Win, I get ntoskrnl.exe missing error. This is my boot info script report:
Code:

I've tried with different boot orders in bios, reinstalling Grub2 (several times ), I've even tried to install lilo through software center but didn't know how to configure it ...
I installed Debian on my PC and then installed Ubuntu. This worked fine and I could dual boot between the two. The PATA disk was /dev/hda on debian and (I think) /dev/sda on Ubuntu. I copied the entire disk to a sata disk using dd from knoppix and put the PATA one to one side. Now the Ubuntu comes up fine but when I boot debian, it complains about references to /dev/hda1, which is present in grub - root=/dev/hda1. Debian now expects sda references rather than hda references. How do I persuade Ubuntu to write /dev/sda1 to the bootloader rather than /dev/hda1 using grub-mkconfig?
