Ubuntu Installation :: Grub Not Detecting Win7 On RAID0?
Mar 26, 2010
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:

New to Linux and am wanting to install ubuntu 9.10 or 10.04 on a single separate 80gb drive. I have Windows installed on 2 80gb drives in Raid0 (nvidia controller) .I have installed 9.10 but Win7 will not load from the bootloader : gives me the error invalid signature. I've looked around and tried a few things to get it to load with no success.. is the Raid0 the issue?
If I try to install 10.04 it will hang and eventually errors out, I believe on the raid drive because it comes up with dev/mapper/nvidia_hhfbdccf1..
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.
installed windows 7..then tried restoring grub using live cd....mounted partition somewhere else....then installed ubuntu again where it was installed previously and now grub is not detecting windows 7 but i am able use my windows files
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?
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?
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
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:
-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 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 am currently running all my applications off a HD as I was unable to install the grub bootloader on my ocz pci express card (grub won't install on the pci express card as it is a raid0 array). I would like to use the HD for backup only and run everything off the ocz card - with the exception of booting (which is unfortunate but I didn't manage to make the pci express card boot). How is it possible to tell suse during the installation to create the /boot on the HD and the rest on the pci express card and also to allocate the remainder of the HD as empty storage area??
