View 5 Replies View RelatedI am trying to recover Grub2 after reinstalling Windows 7 on my computer (which always takes over everything). I downloaded the Ubuntu 10.10 image from here and have mounted the image using the given instructions.
After restarting my computer, changing the boot order, etc., the computer reboots and hangs at "Verifying DMI Pool Data............" I have done everything correctly, so what exactly is causing this problem? Should I restore Grub2 in some different way, then?
i initilally installed ubuntu 9.10 then installed windows 7 ,then i recovered grub2 using livecd as told in the post [URL] i did "sudo update-grub" and got windows 7 menu entry but when i select that entry windows 7 does not load but the grub2 is reloaded again.
i cant boot to windows 7.
Windows 7 have 100 mb partition "System Reserved" the grub2 points to that partition but still windows 7 not loaded.
sudo fdisk -l
Disk /dev/sda: 320.1 GB, 320072933376 bytes

I went through so many post but I haven't found the proper answer yet hope you have an Idea1. Grub2 saves only Linux OS as last selected no Windows OS2.It is possible to boot into a cdrom (drive)?
View 2 Replies View RelatedSorry my previous question wasn't that informative so adding more. I had windows partition and free partition for Linux installation. I got installed windows7 and it installed fine, When I tried installing Ubuntu, I remember selected default options. I gave me default option as it clearly said "1. If you have another operating system (e.g. Windows XP) and you want a dual boot system, select the first option: "Install them side by side, choosing between them at each startup." I thought it would keep Windows as it is and I hit proceeded for installation.
first option: "Install them side by side, choosing between them at each startup." refer [URL] step #4. At the end I am disappointed that I cannot see Windows boot option (Dual boot) It just gives Ubuntu option. I kept 50 GB free space for Ubuntu. Is there any option to recover/switch to windows booting? Or I have lost Windows installation overwritten by Ubuntu?
Today I downloaded the newest version of ubuntu. We have got two laptops, one with vista, one with windows7. Ubuntu did properly install only with Vista. What can I do with the Windows7-one?

How can I set grub2 to ask me this question?
Here is my partition configuration

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 10.04 and Grub won't boot into Windows7. I attempted to fix the problem through several different methods and nothing worked and I fear I made the booting problem worse than it was to begin with. I can boot into Ubuntu just fine, just not Windows7. Black screen with a cursor upper left hand. Windows7 repair disk does not help and using Windows7 command line repairs did nothing.
So here is an idea I came up with: Is there any way I can back up the Windows partition exactly the way it is, reinstall Windows7, and then somehow lay down all that information directly over the install to make it exactly like it was?
I doubt it is that simple, but is that possible? Like basically unhiding all the hidden files, copying them into a folder on my Ubuntu installation, reinstalling Windows7 and just copying them all back?
I installed ubuntu on my dual boot system which had XP and Windows 7 installed, and after installing ubuntu I was able to boot windows 7 and ubuntu, but unable to boot XP it says some dll file is missing, now I think if try to repair xp with installation disk it might ruin my ubuntu.
View 1 Replies View RelatedMy system set-up is one HDD that is partitioned having two Windows7 bootable partitions, and Ubuntu. I originally had Windows7 and Ubuntu, but I wanted to have another Windows7 OS to keep clean for gaming. Of course, when installing Windows7 it wiped out Grub2. I've reinstalled Grub2, but now I'm having a problem in that when I choose Windows7 in the Grub menu, it directs me to the windows boot manager to choose one of my Windows7 partitions to boot. I'd like to configure Grub so I can choose which Windows7 installation I'd like to boot from there. I've tried added custom scripts to point grub directly at the partition where each installation is located, but it always directs me to the windows boot manager. How can I bypass that?

I have Ubuntu already installed Here is the screen shot for you from Gparted. gparted.jpg
I want to use the 72.15Gb unallocated space for Windows7, and I believe that that (Windows) needs to be on it's own partition. I just can't figure out how to get it to its own partition.
I have done some commands in ubuntu 11.04 and got problems, thinking of reinstall it. (laptop acer 5738zg)
Previously when i have dual booted win7 and ubuntu10 and linux mint i always get "grub rescue" when i try reinstall my linux partition, and it ends with i have to do clean reinstall of both windows and linux, which is a major pain in the rectum area
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 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:

View 9 Replies View RelatedI have a laptop that has multiple partitions and was running Windows 7. I installed Fedora in a area of free space in the extended area, thus in a logical partition. Fedora is now running on the laptop. But, at boot time, there is NO BOOT MANAGER. The laptop just boots straight away to Fedora.
I know this has probably been covered, but is there an "official" procedure or document available to us newbies that I can use to recover my system such that it boots all of my installed bootable partitions (including Windows7)?
Suffice to say I had a dual boot at work with an essential windows 7 and non-essential linux install on it, and randomly upgrading the distro made windows7 unbootable. Cue a missed days work, much embarrassment and ear bashing from those who are convinced Linux is written entirely by communists and hippies. In the end I had to re-install windows, which cut off the ability to boot to ubuntu - although I've left the existing ubuntu partitions as they were.
Although I can get away with allocating a few partitions to ubuntu, I can't really justify fiddling with the MBR based upon this experience. I need a fast boot and persistent data for doing anything further with ubuntu at work, so I'm wondering whether a safer bet would be to setup a usb stick with enough grub to boot to the existing ubuntu install? Not a full usb distribution, just enough to boot into the existing install? how this would be doneIs it really just a grub-install /dev/sdXX (where XX is the usb)?
Can I delete the ext and swap partitions from disk management on windows 7 ? Because I want to install a fresh new copy of ubuntu 10.10 . I know it would affect windows 7 boot up.I can handle it by system restore Anyway can I do it or not ?

View 2 Replies View RelatedHi,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

While istalling Ubuntu, after choosing the language, I do not have an option 'Install Ubuntu alongside Windows7'.
View 7 Replies View RelatedI installed Ubuntu 10.10 alongside my Windows 7 installation. The installation was successful, but, now when I try to boot Windows nothing happens (apart from an indefinitely blinking '_'). I tried to do startup repair from my Windows 7 DVD but it is not detecting the hard disk. When I tried to run chkdisk /f from the command prompt it said that the disk is write protected. Later, on using diskpart and list volume the only volume detected is the CD/DVD ROM.
The initial GRUB window points to /dev/sda2 for Windows 7. The Volumes snapshot from Disk Utility is attached!Any idea as to how I can recover Windows 7?
so I just installed Ubuntu 10.10 a couple of days ago and used my whole hard drive.Thing is, I decided that although I loved Ubuntu, I stll want to have dual-boot for some cases.. But now that the disks filesystem is not NTFS, Windows cannot regognise the disk as installable and cannot convert the filesystem. Gosh, Windows is a piece of junk, but I still need them for some occasions.
View 1 Replies View RelatedI have tried many methods but still didn't succeed in rebooting Win Vista (blank page after selecting it in boot menu). The main problems were that GRUB was installed also on Windows partition, and Win partition appears as FAT16 and not NTFS Here is the output of boot_info_script, I would say that everything seems OK.

I installed a bunch of updates on one of my 10.04 systems before the holidays and then shutdown. Upon my return the initial boot greeted me with the "low resolution graphics" dialog and no functional mouse or keyboard. I dual booted to 8.04 and replaced /etc/X11/xorg.conf with the contents of the xorg.conf.failsafe in the same directory and rebooted. Got the 800x600 VESA Gnome desktop but still no mouse or keyboard. I tried booting with a different brand mouse (was MS, tried Logitech trackball) but still no good. I have to press the reset button to reboot
It is not a hardware issue as mouse, keyboard and 1920x1200 graphics all work fine when I boot 8.04, 6.06 or Windows 2000. None of the four 10.04 kernels listed in my boot menu makes any difference.
I installed Windows after installing Ubuntu. But Ubuntu is still intact in its partition.
I'm trying to run the Ubuntu LiveCD to recover grub, but the LiveCD no longer works. It stops the boot process and does not load completely.
I can not run Ubuntu in live mode to recover grub.
Is there any way to recover the grub/grub2 without the LiveCD?
