Ubuntu :: New Dual-boot But Cannot Load Windows7(grub)?
Apr 12, 2011
Finally made the switch over to ubuntu, but I needed to keep my windows7 for several reasons. Let just start by saying I have two hard drives, a 200gig(which holds my windows7 partition) and a 500gig(has a 100gig partition which has ubuntu on it). After finally getting 10.04 to install on the 100gig partition and everything running right, I tried to load up windows7 and got an error.
Something along to lines of "the partition does not exist". I believe I messed up on the last step on the install, as I might of just been careless. I remember reading somewhere that if using multiple hard drives grub may get messed up in one way or another. IS there a way to fix this and make grub realize that window7 is on another partition, or am I out of luck?edit: Id like to add that grub is recognizing windows7, it just will not load off the other partition(I think)

I have a laptop that has a dual boot of Windows7/Ubuntu10.04. Ubuntu loads fine, but Windows 7 does not. It shows up in the Grub, but it will not load. I assume that the boot loader was messed up somehow, but I am not experienced at deciphering the boot info file. I was hoping someone might be able to take a look at the file and tell me what the issue might be, and also which part of the text indicates the problemBoot File:

On reboot the GRUB2 installer shows me the options for OS - I select Windows XP and then I get a blank screen with a flashing cursor - and nothing.. I CTRL ALT DEL and it reboots back to GRUB2 and I select UBUNTU and I log in. This is the first time I have tried to reboot Windows XP after fresh install of UBUNTU

A few days ago I went to perform the Service Pack 1 Upgrade for Win 7. This crashed out with an error. On researching the problem I found a solution to fix the problem by marking the Windows partition as active. I did this (via Computer Mgmt -> Disk Mgmt). This allowed the SP1 upgrade to work, however on reboot I got an error BOOTMGR missing. This I rather rashly resolved by using the Windows 7 install DVD in Recovery mode to reinstall the Windows Boot manager via bootrec /Fixboot I thought I would then be able to use the Opensuse 11.2 install disk to fix grub.
I use the Opensuse install disk and select Repair system -> Expert Mode -> Install New Boot Loader then select Other -> Reread Configuration from Disk. This adds Win 7 back into the grub menu. I then select OK and get the message "the bootloader was installed successfully". The problem then comes when I click my way through OK and Next to finish the install. At the end of the process I get the message "An error occurred during the installation" and I'm no further forward.
FYI the PC has a single SATA disk installed partitioned as follows:
dev/sda1 100Mb Win System Parkition
dev/sda2 Windows NTFS
dev/sda3 Windows FAT

I built this computer with a Gigabyte motherboard, i3 processor, 8Gb ram, 64Gb SSD, and 1.5Tb HDD. Loaded Windows 7 to the SSD... repartitioned the drives and loaded Ubuntu 11.04.The start menu comes up to select Windows 7 or Ubuntu... when I select Ubuntu I get a screen which reads:Windows failed to start. A recent hardware or software change might be the cause. To Fix the problem:1. Insert your windows installation disc and restart your computer.2. Choose your language settings, and the click "Next"3. Click "Repair your computer."if you do not have this disc, contact your sys admin or manufacturer for assistance. File: ubuntuwinbootwubildr.mbrStatus: 0xc0000098Info: The selected entry could not be loaded because the application is missing or corrupt.
This screen continues to come up. I tried to load Ubuntu with Wubi but it would not install... I have now installed it from a DVD but the load screen keeps putting me back to the screen above. I can't load from the Windows CD it won't recognize it even if I change the bios setting.Windows 7 seems to be running fine... and Ubuntu seems to have loaded fine... so how can I get my Windows boot screen to go and load Ubuntu as my OS?

I installed Win7 after Ubuntu (10.10). I attempted to reload grub so that I would be able to run them dual boot and now I can't load anything.
I followed the guide here: [url] and went threw it a couple of times now to make sure it wasn't user error.
I am using a live cd from 10.04 because it's the only one I have. Any chance that's why it isn't working properly? I wouldn't think so, but I assume that it's possible.
If that is the case; Any way to solve it without using the live cd? I cannot burn a new disk because I have to boot from disk to use my computer right now.
I just get a flashing cursor on a blank screen when I try to load.

Is there a way to make my linux go back to original state without reinstall, and if i reinstall, how can I do this without loosing win7 partition and get this awful grub rescue message.

I need to know whether Ubuntu can be hacked when it is installed as a dual boot with W7 by hacking windows and getting access to the Ubuntu partition?
What I would also like to know if this way can be used to put a key logger or screen capture in Ubuntu which installs next time Ubuntu is started?

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.

my NIC drives me crazy and I need some help to gather all relevant informations to file a decent bug report. Maybe someone could guide me through this process.My mainboard is an AsRock Z68 Pro3
[URL]
I use a dual-boot setup with Windows7 installed in parallel to Fedora 15-x64. Whenever I had Windows in use and jjust reboot the system into Fedora, the NIC does not work as expected. Instead it goes in an endless "em1: link up" loop which results in very low bandwith or even complete network timeouts. This happens in Firefox as well as with yum or ping.

If I directly cold boot into Fedora (after the power cord has been removed and the system got completely re-initialized) there are no problems at alll and I get a fast and stable network conection. This also happens with other linux distributions, for example SysRescCD.

Hi,I had a Windows 7 installation and I decided to install ubuntu 11.04 I tried several times but every time soon or later something with grub goes wrong.Most times I get the error "no such partition",once it just halted after "verifying DMI ... " .I fixed windows mbr with "bootsect /nt60 C:" and then tried to reinstall grub with boot-repair .It showed no errors but after reboot I get "no such partition" again.
My scheme is something like :
/dev/sda1 -> the windows 7 system partition NTFS
/dev/sda2 -> partition for windows programs etc NTFS
/dev/sda3 -> partition for files(images/music/videos) NTFS
/dev/sda4 -> extended partition

So my computer has ubuntu 9.10 installed 1st and I want to install win 7 in a separate partition. Basically, ubuntu 1st, win 7 later so far from what I learned from search results, grub 2 have problem with win 7 installed later and what was recommended was install win 7 before ubuntu. how ever I do not have the time to start over again because there are too many things to back up or install again. can I simply revert grub 2 to grub 1 again and resolve the problem?

I'm trying to take my current windows7 (x64) setup and make it into a dual-boot setup with slackware 13.0 (x32) and am hitting a brickwall. I guess I would like to know if I can salvage the situation without formating my windows drive. I fully intend to, but I had hoped to not do it this month. I'd like to get dual boot going so I can master it and acquire all the files/drivers I'll want and then format and do it 100% right next time.
Currently I have windows setup on a 3x 500gb Raid0 onboard array which itself has been flawless. After I shrunk my current partition size to give me about 25gb of free space I proceeded to setup Linux, and I was unable to perform the cfdisk portion for partitioning the array for Linux.
I tried using cfdisk:
/dev/hdx (a1-a3,b1-b3)
/dev/sdx (a1-a3,b1-b3)
I even attempted to locate with: cat proc/partition and tried using cfdisk on every device it located. It always said it was either an unknown partition table and should I start at zero, or bad partition. I was of course too concerned over my windows setup (which has almost 1tb of stuff I have not backed up) to go any further into the unknown.
PS: I have used Slackware before, back at 8.1, 10, and even a very brief interlude at 12.0, this is my first attempt on this computer however with 13.0, it is currently running fine on my laptop and my PS3 (Laptop is even dual booting 7/Slack13. Albeit without raid)

I have upgraded to ubuntu 10.04 but now can't boot into win vista, ubuntu and vista are on grub but vista will not load, I have tried sudo upgrade-grub which seemed to work but had no effect on loading windows. I did think of using win dvd to fixmbr but only as last resort, I entered the commands suggested by nitstorm and got "command not found". Followed link to source forge.net and test disk, followed the instructions to install and run test disk which repaired the boot sector in the vista partition, I can now choose to boot into win or ubuntu.

I had karmic koala installed a few months back, but wasn't using it cause i didn't have time to properly configure it. Last night, i was thinking of probing around with it a little and found an update for it and went ahead and installed it. After rebooting, GRUB refused to load any of the OSes, but i was still able to access ubuntu with a reduced graphics option (safe mode?). Tried reinstalling etc etc but nothing worked. In my frustration, i whipped out my windows CD and deleted the partition for ubuntu.
Now, after the loading of bios, i get "error: no such partition. grub rescue>".Is there anyway i can get delete grub and get my vista to boot normally? or would i need to reformat everything again? maybe someone can point me in the right direction if a similar thread had been posted before.

I managed somehow to successfully install a dual boot with Ubuntu 9.02 and Windows XP. Ubuntu was on a PATA drive and the WinXP was on a SATA drive. The SATA drive was configured to boot first. As I was having problems with Ubuntu I booted into WinXP, re-formatted the PATA drive, then restarted the computer and installed Ubuntu 9.10. It all went well.I rebooted the machine and the following message was on the screen:
GRUB Loading stage1.5.GRUB Loading, please wait....Error 17
I rebooted, changed the boot order so that the PATA disk (Ubuntu) started first, then the SATA(WinXP). Ubuntu loaded up the dual boot screen.I chose WINXP, but I was greeted with a black screen.I rebooted again and chose to load Ubuntu, which it did without a hitch.what I should do to restore my access to WinXP? Or should I start again? If so, how?

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.

I've installed Ubuntu on my new desktop alongside Windows 7 (each OS is on a separate drive), I seem to have run into a small problem. Let me start with what I did:
- Unplugged 1TB drive from the PSU, BIOS was not seeing my formatted (and thus empty) 500GB drive and I couldn't put it into the boot order at all with the 1TB turned on.
- Loaded up the boot CD and was able to install Ubuntu 10.1 on my 500GB drive.
- Did a bit of configuring, shut my PC off and plugged my 1TB (with Windows 7) drive back in. I tried to see if I could now see my Ubuntu drive in BIOS but nothing is there - just the Windows drive is in the list of available drives to boot from (along with DVD-ROM and USB).
This is where I've run into my problem. What I want is to have a nice GRUB boot menu at the start like any other dual-boot system but just have the two operating systems on separate drives altogether.I did it this way because I was having issues with the advanced partition menu on the boot CD so just went ahead and followed the KISS method by unplugging the Windows drive.
I was told by a friend that if I put my Ubuntu drive into the first position in my boot order and the Windows drive in the second, then I could boot into Ubuntu and run a GRUB update command (he told me to google it) and that would create the necessary GRUB that had the entries for Windows 7 and Ubuntu.Both operating systems are 64-bit, I imagine that might make a difference in whatever help you guys can offer me. I love the hell out of both OS's and want to be able to use them interchangeably.

i am having a problem with my dual boot setup. I originally installed windows XP on a 100gb hard drive, from there i downloaded and burnt ubuntu off so i could install it on my 200gb hard drive. For a little bit i struggled to even get it to install because it wouldn't recognize my onboard nvidia graphics, i ended up having to get an alt boot disk and fix it with technique in this link:

Now after the bios boot, my screen shuts off for awhile and takes me directly to the login screen for ubuntu. No Grub, no windows boot options, nothing. I tried booting windows by choosing it from the bios boot menu but all it does is hang at prompt and doesn't boot at all. I tried the live cd fix and reinstalled grub but nothing changed. What i think is happening is that it boots the Grub menu but it doesn't display it because of graphical confrontations. It hangs for about 10 seconds, the grub default time, and then turns my monitor back on to display the Ubuntu login screen.

I followed a tutorial to install XP across my entire HDD. I installed Ubuntu 10.10 "Alongside another OS". Ubuntu loads fine, but when trying to load XP, the boot screen shows up, but then the computer restarts and returns to the GRUB menu.
I saw some threads on this site and tried to type: sudo gedit /boot/grub/menu.lst
In the terminal. It returned a blank text document so I'm not sure if that information was outdated. I then typed: sudo fdisk -l
And got this:
Not sure what any of this means, but I sure hope someone else does. I would say forget XP, but it's hard to let go of some of the games and software I use. I appreciate any responses, thank you.
I tried to format the table as it appeared, but the forum corrected the extra spaces.

I had a dual boot system with 3 partitions, Windows 7 on one partition, and Windows XP on another partition and a Data partition. I decided to load Ubuntu 10.10 on the Windows XP partition.During installation I selection manual partition, and deleted Windows XP.after successful completion of Ubuntu installation "Grub" directly boots into Ubuntu, it doesn't show me the OS selection screen. After following some forum posts I did an update grub
Code:

I'm trying to install OpenSUSE 11.4 (64bit with the server options included) on my Mac (Core 2 Duo 2.0 Ghz with 2 GB memory). So I have sda2 the OSX, sda1 swap, sda3 is the bootcamp (windows), sda4 (ext4) and sda5(ext5). I installed rEFIt 0.14 first, then I reboot with DVD on. The installation setup resized the Windows partition from Bootcamp, and create 3 other partitions (the sda1,4 and 5). At the installation I choos MBR enable and "/" as home enable.
At the end of the installation I have the error about MBR, that can't mount, or create the mount point? I'll double check the exact message. Anyway, when I try to load OpenSUSE, is not working: can not load the system. I tried to find on the installation menu a repair (I thought that I can find an utility to fix the MBR). I don't want to choose other distribution, because I used SuSE before, and I really like it, and of course this way I can learn more about troubleshooting a Linux installation on different environment

Just installed Slackware 13.37 and am trying to get dual boot to work properly. I have edited /etc/lilo.conf to point the Windows section to what I believe should be the correct partition (/dev/sda2) Here is the relevant section
Code:
# LILO configuration file
# Windows bootable partition config begins
other = /dev/sda2
[code]....
I have mounted /dev/sda2 to /ntfs-c as suggested during install and when I browse through there I see the files from my windows setup so it is in fact the correct partition. When I load Windows on boot, however, it is pointing to the recovery partition (/dev/sda1).

I updated from Ubuntu 9.10 to 10.04 via Ubuntu updater. Worked nicely. Until I had to use Win 7 for a moment, so I went to the Grub boot menu and picked Win 7. Nothing is happening. Just a black screen with blinking underscore to the top left corner. I never had this problem with 9.10, so I am confused. I tried looking around and nothing helped. Be noted that I am an amateur with Ubuntu coding and installing. I did hear that this is already a common issue now.

I messed it up with the grub in Ubuntu Netbook and the grub loader just prompt the "grub console" during the system boot.
However, I can boot manually by selecting manually the kernel:
Code:
kernel /boot/vmlinuz-2.6.32-24-generic
boot
But, of course, that is not really practical for an everyday use.
I tried with the update-grub command, but nothing happens, the grub.cfg is there, with all the kernels list, but the grub loader won't load it! It is just ignoring it!
If I load the config file manually it prompts the grub command line again (with the "welcome" message), so, it IS loading the grub.cfg, but it's not working!!!
This is the content of my grub.cfg file:
Code:
#
# DO NOT EDIT THIS FILE
#
# It is automatically generated by /usr/sbin/grub-mkconfig using templates
# from /etc/grub.d and settings from /etc/default/grub

I'm having installation issues with linux. I'm trying to set up a dual boot with vista and linux. I prepared my computer by backing up my files and partitioning my hard drive, leaving 20GB for linux. I downloaded Linux Mint 7, and booted from USB (using the universal USB installer from pendrivelinux.com). All good, entered into linux and installed by following the prompts (selecting use largest unallocated partition to point linux to the partition). At this stage the screen cleared to just leave me with the desktop background.
I patiently waited for it to reboot which never happened. So I waited for 20mins or so, then shut the computer down because I couldn't think of what else to do. When I restarted (without using the livecd/usb) it just went straight to vista. I did a bit of reading and found it might have been something to do with vista taking over grub, and some of the tutorials suggested downloading EasyBCD. So I did that, here's the summary:
Code:
There are a total of 2 entries listed in the Vista Bootloader.
