I attach the boot info results.
View 8 RepliesI have a major problem with Windows 7's MBR. I deleted Ubuntu's partition last night, and when I restarted, I saw:
Code:
error: no such partition
grub rescue>
I looked it up, put some code into a LiveCD terminal, and I thought it worked. But now, I says that I definitely need to put in a Windows 7 CD and do that MBR fix method. I did not own a Windows 7 CD; my laptop came with it pre-installed, and I have no recovery partition anymore.
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 have 2 hard disks. sda,sdb
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.

View 3 Replies View RelatedI run 3 OS's: Win vista, win 7, and ubuntu. Every month I reinstall windows 7 (because I dont have a key), and everytime I do that it reinstalls the MBR. After that, I cant access ubuntu. I have used live cd's to try and reinstall grub with no sucess.What is the easiest way to achieve this? I was hoping I could make a CD to pop in my computer that could reinstall grub as it should be, or atleast boot me into ubuntu, and work from there. But even if I get into ubuntu, I dont know the commands to reinstall grub with autodetect of the other OS's.

Yesterday I made a mistake and formated the ubuntu partition as ntfs with a windows media because I needed to do a test in that partition. Now, off course, when I boot the computer is not finding GRUB and naturally not booting to windows.
I tried to boot with ubuntu live cd and did the apt-get install ms-sys but it just does not find the package. I can browse the windows files and all of that.
I had dual boot Win Xp and CentOs Linux. I have small harddisk and needed more space, so I removed CentOS linux with partition manager and rebooted. Now I can not boot my XP. All I can see is GRUB prompt. Keyboard do not respond except CTRL ALT DEL. I know I have to fixmbr. But I can not boot from my bootable XP CD. I can boot from CentOS linux DVD and enter into linux rescue mode. From that I typed "grub" entered into grub. Then I tried
root(hd0,0)

chainloader --force +1
boot.
But it gives me some error. Can I boot my XP from CentOS DVD rescue mode?
I have 3 hard drives and have Ubuntu installed on one (sdb), had windows vista installed in the other (sda) and use the other (sdc) as a back up/extra space. I just deleted the windows vista partition and formatted the hard drive (ext4) and now just use Ubuntu, however, in the grub boot, vista and recovery is still showing up. How can I clean the grub up and delete these entries. I've searched all over the place, googled like crazy and all I can find is how to get rid of grub or reinstall the MBR of vista (etc). One more thing, how can I permanently mount the new empty hard drive in Ubuntu so that I have access to it all the time w/out having to mount it.
View 5 Replies View RelatedWindows 7 x64 was the only install with a separate boot partition which was already on the Dell laptop. I then shrunk the partition to allow me to put opensuse on. Then I made the stupid mistake of deleting the opensuse and boot partitions while in Windows. I was going to do this, copy pictures of my new born baby off then reboot and delete all stuff and redo all the partitions and installs again.Now I just get grub rescue with the following when I do ls command:(hd0) (hd0,1) (hd0,2)I would like advise on how to get the data off, I cannot afford to lose my babies pics as there are no other copies. I will then do a normal install of opensuse first then Windows 7 after it.
View 6 Replies View RelatedI'm a CS Major that wanted to experiment with Linux more. Great idea right?! Well, long story short, I have a HP Dv9815nr Entertainment Notebook PC with Vista pre-installed. I have 2 local SATA HDDs and installed Vista(250GB) and Fedora 12(160GB)(respectively). In order to make life simple for booting purposes, I partitioned the Vista drive to include a 3GB sector for the Fedora Boot partition, so that Grub would run properly.
I recently discovered Sun's VirtualBox (Open Source Virtualization software) and installed several flavors of linux inside of this application on the Vista Disk. Naturally, I installed Fedora 12 in the Virtual Box and reformatted the Linux drive (160GB + 3GB Boot partition).
Everything was fine and then I rebooted. Now I get a Grub error on boot. "Error 22 : partition not found". I would like to restore the Vista MBR using the Fedora 12 Live cd, but I can't repartition the Vista drive under the live installation.
Also, I extended the Vista partition to include the 3GB previously used for the Fedora Boot Sector.
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 installed Ubuntu first, then Windows 7.
use Fedora 15. I had installed driver for my ATI graphic card, as it was written in Fedora guide, then when I rebooted the system the bars and icons appeared with strange, changed colours (purple, green, etc). I've read that this happened because of the bad drivers, so I tried to fix it. Unfortunatelly because I'm Linux newbie and I'm also very nervous I deleted (using Fedora software manager) everything connectedtalyst from my system.Now when I try to start my computer, grub starts in text mode.My question is:What can I do? Do I have to reinstall my system or maybe someone knows how to fix it?I'm quite scared because now I can't launch not only Fedora but also Windows.(I'm writing from another computer

I want ot install a new opensuse 11.4 as yest another OS. Due to the fact that I already have 4 sda partitions, I have to make some changes. What I am thinking about is to copy the sda2 (windows recovery) data to some folder etc (nevermind), then delete the sda2. Then I want to create a new primary partition for the new suse 11.4 and install it. What is worying me is the grub boot menu. I was planning to edit the new one (the opensuse 11.4), with old data.
Code:
###Don't change this comment - YaST2 identifier: Original name: linux###
title Desktop -- openSUSE 11.2 - 2.6.31.5-0.1
root (hd0,3)
kernel /boot/vmlinuz-2.6.31.5-0.1-desktop root=/dev/disk/by-id/ata-Hitachi_HTS542525K9SA00_080105BB0F00WDHE41DC-part4 resume=/dev/disk/by-id/ata-Hitachi_HTS542525K9SA00_080105$
initrd /boot/initrd-2.6.31.5-0.1-desktop .....
Now my question is will the settings of (hda0,n), change due to the fact that I have deleted the sda2? I have a lot of unused space at the end of my disk and want to create a new "sda2" there.
Last night, I formatted my laptop(Asus w5f). And I installed win7 Home Premium. Then I installed Ubuntu 10.04. After installation, I restarted the computer. When I choose win7 at grub, comp. restarted itself. But When I choose Ubuntu, started properly. Now, grub is not starting win7. At ubuntu, I can see windows disk and files. But win7 doesn't start.
View 2 Replies View RelatedI finally got it and windows 7 installed on separate hard drives. Windows installed first, then ubuntu 10.04.01. Had to use the alternate ubuntu install cd to make it work. During the install it said there were no other operating systems installed on the computer and asked if grub could overwrite the master boor record. I knew this was something I wanted to do and if it was wrong it could most likely be fixed later. So that being said, ubuntu has taken over the boot of my pc. No grub menu pops up. Not sure how to add windows to grub to make it give me a choice. I did try pressing shift during startup to get grub to load, and nothing happened.
Here is my fdisk.

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?
[Code]....
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)

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?

My tech savvy friends built me a computer and put win7 64 bit and then installed ubuntu (upgraded to 10.10) and had grub so whenever i turned my computer on i could choose between linux and windows and everything was fine. The other day i couldn't boot into ubuntu so i went into my win7 partition and deleted ubuntu and all other partitions and/or extensions thinking that it would get rid of ubuntu. Now when i boot it doesnt recognize anything so i tried booting from my ubuntu cd (don't know if its 10.4 or version) and it will load and when i try to install it i get the grub recovery thing and then the initramfs thing and the error "initramfs Can not mount /dev/loop0 (/live/image/live/filesystem.squashfs)"
i don't need ubuntu but i do need windows as it has files and papers that i need this week.
I've resized partitions with some program - perhaps even gparted - but from Win7. partitions are indeed resized, but now I can't boot Win7, grub says:
"No such device found - No such partition found".
I tried to use some advices on similar problems I found here (like adding GRUB_PRELOAD_MODULES="part_msdos" to etc/default/grub and running grub-mkconfig after), but nothing helped. I guess I could restore win7 with installation dvd but I want to fix GRUB (and have both ubuntu 10.10 and win7)

I want to know about grub. Let start with the explanation of grub. I am using Ubuntu 10.04. Yesterday when I installed widows7, I lost my grub. Every time I tried to install windows running on Ubuntu machine, the grub is lost. Why is it so? How can I restore it (for Ubuntu 10.04)? Can any advance setup be made while installing windows, so that the grub is not lost?

Only problem that I used to have was the sound didn't use to play when I boot through Ubuntu. Due to that, I formatted the corresponding drive from Windows in which there was Ubuntu installed. I used "diskmgmt.msc" to delete the partition and then format it. The format was successful and when I restarted my computer, this error was displayed:-

Windows didn't load at all. I used to have multiple boot grub menu previously before formatting the partition but that didn't show up after formatting.I am unable to use any of the Operating System.
