Ubuntu Installation :: Replaced XP With Win7 - Need To Change Grub?
Aug 28, 2010
I had XP Home on my dual boot Ubuntu 10.04 LTS amd64 PC & now installed Window 7 Home Premium 64-bit over old XP. Before installing Win7, as a precaution, I disconnected the hard drive where Ubuntu is installed. Now, naturally, the startup screen (grub?) still offers XP. Is there an easy way to re-detect & rewrite the startup menu with the Ubuntu install CD without re-installing Ubuntu 10.04 LTS amd64 again, like a GRUB repair or rewrite?
Just installed Ubuntu 10.10 onto my new netbook from a USB stick. The laptop came with Win7 Starter, which I kept on a small partition. Installation was apparently successful, but when I start up the computer, it will go straight to Win7 and GRUB doesn't appear.
I was using ubuntu 11.04 with a separate boot partition. Then i installed fedora 15 during which i erased(format) the /boot partition which holds the Grub2 entries for ubuntu. And its been replaced with the Grub's of Fedora. My Ubuntu installation is still intact sans the /boot folder. i tried copying the ubuntu vmlinuz and initrd into /boot (now belonging to fedora) and booted from grub - it throws me into initramfs , from which i dont know how to get into the lovely GUI of ubuntu .
[Code].....
where /sda1 is boot ; /sda7 is home ; /dev/sda10 having the [once] ubuntu installed files without /boot folder ; /dev/sda3 my fedora installation from where am typing this. Can i make a dual boot of ubuntu and fedora now without the need of reinstalling ubuntu again
In sda, I have 4 partitions, and I have windows 7 in one of the extended partitions [not in the primary partition].
In sdb, I have 3 partitions. 2 for storage, and 1 10GB drive for Ubuntu. Again, Ubuntu is not of a primary partition.
I had ubuntu 10.04 running on that for a long time. However, I wanted to reinstall ubuntu and use 10.10.This is what I did EXACTLY:Booted from Ubuntu install CD
Chose advanced istall
Selected sdb3 for Ubuntu
I installed GRUB2 on the SAME partition as Ubuntu aka sdb3 Installed then rebooted
I can boot into Ubuntu fine, but whenever I select Windows 7 bootloader from the GRUB menu, the screen goes black, and my PC reboots.
Boot Info:

ls: reading directory sda6/: Input/output error
I have tried the testdisk/update-grub method, but it didn't work.
i have ubuntu 10 and win 7 dual booting on one hdd, all of a sudden grub says error no such partition when i select windows at the boot menu. and i cant get to the win7 partition from ubuntu (to play music and stuff, this used to work, places, mount filesystem, 250 gigs whatever). i've tried the stuff in these links and nothing has worked so farpartition info

I set up a dual boot system with Win7 and Ubuntu 9.10. Ubuntu is the first OS listed in the boot menu. I would like to change the boot order so Windows is first. Also after running a few updates I now have multiple boot items listed for Ubuntu that I'm sure are no longer needed. Having never edited Grub and searching through the forum, I'm asking help. I going to guess that I want to edit grub.cfg. If so, what do I need to change within the following information?
Looks like Grub2 on my new installation of Ubuntu 9.10 is not picking up a Windows 7 installation on a RAID0 array (using the built-in RAID software from my Asus P5Q-Deluxe)
Here are the results of the boot info script:
Code: Boot Info Script 0.55 dated February 15th, 2010 ============================= Boot Info Summary: ============================== => Grub 2 is installed in the MBR of /dev/sda and looks for (UUID=43b4cb20-dfea-4513-80e9-54d066107c71)/boot/grub. => No boot loader is installed in the MBR of /dev/sdb
I just finished my Windows 7 reinstall, and I go to reboot into Linux, and there's not grub loader. I go into a live CD and get into the grub prompt. Here's what I got: sudo grub grub> root (hd0,0) grub> setup (hd0) Error 17: Cannot mound selected partition
As for additional information, my fstab is listed below: aufs / aufs rw 0 0 tmpfs /tmp tmpfs nosuid,nodev 0 0 /dev/sda6 swap swap defaults 0 0
how do i correct my boot loader after installing Win7 on the free space available. i still have my fedora 13 partition intact. but of course, fedora option is not available. how do i re-install grub using the rescue dvd? tried alrerady.
My machine is an hp 2133 mininote. It came factory installed with Windows vista, which repeadtedly crashed on me. To compenstate for this i installed gOS to dual boot with Vista. This was working fine but I was recently given a Windows 7 install disk, so I decided to upgrade. Windows seven installed without a problem but now I can't access the GRUB bootloader, windows 7 just loads automatically. I tried to restore it using the Super GRUB Disk usb utility but it didn't work, windows 7 still boots regardless.
My ubuntu 32-bit 9.10 compiles kernel a few times, and now I realized my Win7 lines disappeared. First time when I made the dual boot system, I remember there is a line for Win7, and able to boot up Win7. And then I ran compilations 2 ~ 3 times, and now I see the lines gone. I know 'editing GRUB' is risky, and want to hear advice how to fix. - Actually I don't think I can edit grub.cfg file manually. In my Ubuntu Desktop menu, I still see and mount the Windows disk (physically different partition)
early tl;dr: The fancy grub breaks on my wubi 10.04 install, can I force it to use the old grub?
When I rebuild grub.cfg (last time was yesterday for kernel update to .37), and shut down / reboot, grub breaks because it can't 'loadfont' and a few other errors which are related to the 'graphical' grub boot menu.
To fix this I have to boot into a live CD (also Ubuntu 10.04) and run the following: Taken from [URL]
Code: sudo fdisk -l sudo mkdir /win sudo mount /dev/sda1 /win sudo mkdir /vdisk sudo mount -o loop /win/ubuntu/disks/root.disk /vdisk
[Code]....
I know how to fix it but is there a way to skip having to do this on upgrades (If I edit the grub.cfg before shutting down then this doesn't happen, obviously, but sometimes I forget and this is the result. I'd rather stop the problem at it's source than fight against the updater).
Firstly, I installed my Windows 7 on sda2; then, I installed Ubuntu 10.04 on sda1. But the computer directly get into Ubuntu without listing the grub list. How to get the Grub list back and make sure the Widows 7 is on the list?
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.
Im a newbie having the opposite issue that seems that everyone is having for what Ive seen, I have Grub on the MBR, showing the splash screen fine (the background image also), and allowing me to boot Windows 7, but I get a cursor blinking for the eternity when trying to boot Fedora 13.My hardware is:
Quote:
-ASUS M4A89GTD PRO (AMD 890 FX AM3 Chipset). -Phenom 965 BE. -4Gb RAM. -3 x 250 Gb SATA Hard disks, first one alone for OS, and the other two in fake RAID1. -1 x 80 Gb IDE hard drive containing trash. -RADEON HD 4870 1Gb Graphic Card. -RME HDSP 9632 Soundcard
I just installed Win7 (I need it for work -.-") and, of couse, it installed its boot loader and I can't boot F13 any longer. The question is, how do I restore GRUB from a F13 live installation media without destroying Win7?
I remeber trying something like that a couple of years before when I had the same issue:
Unfortunatelly, that doesn't work and at the next boot I am stuck with Windows again how to restore grub from a F13 live CD?
I'm having serious troubles to install ubuntu-10.04.1. My raid is an hardware raid with intel chipset. Note that win7 is already installed and working with my raid. I made some space from windows, to install Ubuntu (40gb). First, I run the installer, everything seems to be fine. I choose to install Ubuntu were there is the most space free (sorry, I'm not sure about the real terms used there).
Then my partition with the vista loader appears. So the installer can see my raid, and should work fine (everything is detected correctly). But once I'm in the end of the installation (around 95%), a pop-up appears, and tells me that Grub can't install in /dev/sda and it's a fatal error. I can choose an another destination, but it doesn't seems to work.
1. Install kernel: see #2 (I make it with kernel file in /var/cache/apt/archive)
After installation of kernel, there may be some problems:
2. Win7 disappear in the grub: see the content below "Not see Windows 7: ", #6 3. Cannot connect to the network: see #8.
Quote: While trying to remove old kernels, I delete all of them by accident!!! There're now only two "Memory test" and a "win7" in the grub. Since there's lots of data on the disk, and I have no idea how to keep them safe if reinstalling the system, so I really hope not to do that.
Then I enter Ubuntu 10.10 cd, and sudo apt-get install a kernel (three 2.6.35 or so, of which two with "generic" and not, and one with "image"), everything seems OK. And I guess what I did really changed the system, since the source_list file in the /etc/apt/ did be changed. But the grub still has only 3 options. What else should I do to add the newly installed kernel to the grub? Or What should I do while I delete all kernels by accident?
I'm having an issue installing Ubuntu with Windows 7 Home Premium 64-bit through Wubi. The Wubi installation works great and Ubuntu seems to install after the first reboot after selecting Ubuntu from Windows' boot menu, however whenever I select Ubuntu from Windows' boot menu after Ubuntu installs and it reboots for the second time, it loads the GRUB bootloader, however Ubuntu isn't listed at all.
Windows 7 is listed twice and Windows Vista is listed (seems it picks up the recovery partition for Windows 7 as Vista) and when I select the first Windows 7 from the GRUB bootloader, it just goes back to Windows' boot menu with Windows 7 and Ubuntu as the selections. If I select the second Windows 7 from the GRUB bootloader, it'll boot Windows 7 like normally. It looks like Ubuntu is nowhere to be found. Because of that, I just ended up uninstalling it.
I just installed Fedora15 on my laptop. When the installation completed, the system rebooted and gave me a Grub Error 17. I logged in the rescue mode and got the following output from
Code: fdisk -ls

The first is I seem to have 3 GRUB installs. So whilst I update the one from my live session, the change does not appear in the boot up menu. I had installed 10.10 from a CD into a different partition (sda6), but that will not boot, so I have just deleted this and done another grub install and update. The kernel I am using has just been updated from 10.04 to 10.10 too, and it is this that I use and the Grub I have been working on (sda5).
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 installed ubuntu after windows 7 but now i cant boot windows 7 i tried the start up repair and I've read through some questions answered on here and int figure out the problem i don't want to uninstall ubuntu unless it's my only option
I recently installed Karmic, and want to change the default Grub entry to Windows XP. Having done some research and tried things out, I am a bit confused. I have edited etc/default/grub so that it has GRUB_DEFAULT=6 (to correspond to my XP installation) and GRUB_TIMEOUT="3", but after running sudo grub-mkconfig the grub.cfg file still says set default="0".
I just upgraded to 10.04 from 9.10 and when I choose to boot to my Win7 Pro it just loops back to the grub menu. I did choose the partition that Windows is on when I was upgrading and it shows up in the menu.
I updated Ubuntu and part of it was an update to grub. When it came up in the installation I told it to keep the old one and left everything as it was. Then when I tried to reboot into Windows it gave an error message. So I went back into Ubuntu and reinstalled grub and now when I select Windows it just loops back to grub.
