Ubuntu Installation :: Restore Grub After Using Fixmbr In Windows?
Sep 1, 2010
I need to use the fixmbr command to fix my windows installation. I'd like to restore grub to its former state after doing so. I have searched how to do this and since my configuration differs slightly, I'd rather get more specific instructions. Right now this is what menu.lst looks like:
Basically, I used a USB stick to run ubuntu 9.10 live, then tried to install to an external 500gb HDD connected with a Sharkoon Drivelink USB adaptor. The installation went fine, but I get a GRUB error 21 when booting a lot of the time. I figure this is due to the way in which the drive is connected. I am a complete noob, and I want to just ove GRUB completely and restore my Vista bootloader. Unfortunately, I do not have an installation disk as my laptop didn't come with one, and none of the others I have other PC's are the same version (home premium 32-bit).If you know of a way to fix the GRUB issue/sso I can use the external drive I would love to hear them too, but the main aim of this thread is to help me remove GRUB and restore the windows bootloader. If any more information is needed, just ask and I will provide it.HP Touchsmart TX2-1010Windows Vista Home Premium 32-bitExternal HDD:Seagate Barracuda 7200.11 SATAII (with jumper set for 150mbps)
I had i a dual boot win. 7 and ubuntu 9.10,recently i had some problem in my windows os so i restored the c drive to factory settings since both operating systems where in c drive so when i tried to boot grub was showing problem.the information displayed was loading grub, the file does not exist rescue grub> so what should i do to restore grub so that i can boot again into windows 7 and ubuntu without loosing my data.
Now I would like to uninstall it and use Windows XP instead. But when booting from the winxp disk, the only partition I can see, is the flash drive I am installing from. I was told to uninstall grub, but the fixmbr command doesn't do anything for me.
I've been using opensuse 11.2 and windows xp at parallel. After I decide to reinstall windows, I got the error saying "invalid partition table" after the first restart of windows xp installation.
I tried to use windows system recovery console and committing fixmbr and fixboot commands, but didn't work.
After all, i boot with opensuse livecd to run the grub and got my opensuse back.
How can I installed windows on a opensuse installed system? My plan was first to install windows xp, then opensuse again.
Is there any way to simply remove grub? Does GRUB reside in a specific partition? Do I have to just delete the partition that has GRUB on it?The way my bootable partitions work is something like this.
1)Installed Vista
2)Installed Ubuntu
3)Thought I removed GRUB
4)Put in new HDD(1) and installed Win7 onto it
5)Put in another new HDD(2) and put another Win7 onto that (but I disconnected every other HDD so that the bootloader would be written onto the new HDD(2). When I have all my HDD's plugged in now, I get a GRUB load error (I think it's 21).
have an Intel Core2 Duo system that would dual boot via GRUB between Windows Vista and Fedora 10. I recently attempted to upgrade from Vista to Windows 7, however because the version of Vista I had would not upgrade to Windows7. This has removed the ability to boot into my Fedora 10 installation. After some brief research on the Internet, I created a Live CD of Fedora 12, and booted into that. Accessing the terminal I tried typing:
[liveuser@localhost ~]$ su root [root@localhost liveuser]# grub
Probing devices to guess BIOS drives. This may take a long time.
GNU GRUB version 0.97 (640K lower / 3072K upper memory) [ Minimal BASH-like line editing is supported. For the first word, TAB
[code]....
Error 15: File not found
What is needed so I can restore GRUB on my system and boot into Fedora again?`
My problem is that I have installed openSUSE 11.2 on a laptop with Windows 7 already installed. Yast resized my Windows partitions, which seemed to upset Windows as I had to go to my Windows Recovery Disc to restore it. When Windows was restored it did something so that GRUB no longer appeared. So I did a system recovery for openSUSE 11.2 which then removed Windows 7 from GRUB! Now I'm trying to restore Windows 7 and configure GRUB so that Windows and openSUSE will stop fight for boot supremacy and play nice with each other. Here are my Yast2 Boot Loader settings:
Section Management Settings SUSE LINUX (type)image (/dev/sda6, root=dev/disk/by-id/ata-ST9320320AS_5SX4PRAS-part6) Failsafe SUSE LINUX (type)image (/dev/sda6, root=dev/disk/by-id/ata-ST9320320AS_5SX4PRAS-part6) Boot Loader Installation Settings Boot Loader: GRUB Boot Loader Location: Boot from Extended Partition Disk Order: /dev/disk/by-id/ata-ST9320320AS_5SX4PRAS
Installed windows xp on new ata Hdd and added ubunto next; got error 18 ; used the Fixmbr at the win console for repair; able now to access my windows but not the Ubunto; I guess Grub removed on repair. Would like to bring ubunto back.
I just made my system unbootable... Here is what i did.. I have two sata HDDs
160 GB (Contained Windows 7) 500 GB
I copied entire 160 gb as an mirrored image to 500GB HDD using Acronis Disk Director. I deleted entire 160 GB HDD.. Removed the 500 GB HDD and kept it seperate.. Installed ClearOS Enterprise 5.2 Worked a little bit... The i wanted to delete ClearOS.. So i connected 500GB HDD and booted again in Acronis Disk director Formated the entire 160GB HDD.. Copied back the entire 160 from 500GB HDD.. Now my sytem refuses to boot... Just 4 letters "GRUB" appears on the screen... I tried booting using XP CD.. It gives a blue screen.. I tried Windows 7 CD.. It says unable to fix due to MBR problem..
I have installed Kubuntu on a usb stick. I installed version 9.04 from a disk that came with linux magazine. After installation I can only boot pc if the usb stick is plugged into pc before I turn it on. I then gat a menu with 5 options. The first is Kubuntu and the last is Windows XP. If I try to boot my pc without the usb stick plugged in I get a GRUB error message.
I think this is the GRUB menu which means that it must have amended the Master Boot Record. If I try to boot my pc without the usb stick plugged in I get a GRUB error message. This is generally a minor inconvenience and a great security measure. My worry is that I am notorious for losing usb sticks. If I lose this one I wont be able to boot pc. Is there a way to remove GRUB and restore the MBR?

I had windows XP and Ubuntu installed on my Asus 1000HE and the hard drive is failing so I need to RMA it. They told me to restore it to factory defaults which I just press F9 at boot 3 time and Ghost takes over and reformats, creates 2 partitions and installs XP on one of the and the other is for another OS or just storage if needed.
I did that now I get a grub rescue prompt when I boot my netbook. Is there a way that grub installed itself to my PE partition that's a hidden partition that came with the netbook? I've taken the drive out of the netbook and put it into my desktop and formatted both main partitions but not the restore one. Yet I still get the grub rescue prompt, how can that be?? I can't even boot from flash drive or get to bios it just goes straight to the rescue.I need to send the netbook back but can't unless its restored. Right now I'm on the 9.10 live flash drive I made on my desktop and my only hard drive attached it the netbooks.
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 do computer forensics here in Afghanistan and I am trying to keep a clean image of a dual bootable hard drive. Here is what I try to do...
1. Boot into UbuntuLiveCD 2. I run "sudo dd if=/dev/zero of=/dev/sda conv=sync,notrunc bs=64K" to wipe the drive with all zeros. 3. I then install Windows by creating a new partician about 50GB. 4. I then install Linux by creating a partician in ext4 mounting it at '/' in addition I create a swap partician. 5. Next configure everything just the way I want it. I install all the drivers and software I need for my windows partician and build out the remaining part of the disc as a "data drive." 6. Then I use "dd" again to try to image my "clean slate" of a system. Remember I am dual booting. I dd the /dev/sda and gzip it. 7. When I go to restore it, I boot from the live CD again and unzip ig and "dd" it back onto /dev/sda. 8. I run fdisk -l and I get:/dev/sda1 * 1 6375 5120000000 7 HPFS/NTFS/dev/sda2 6376 11724 42965842+ 83 Linux/dev/sda3 11725 12453 ...... 82 Linux swap / Solaris.This means to me that it can "understand the file system" 9. But then when I take out the Live boot CD and try to get my "clean slate" machine back, the system goes into Grub Rescue mode with a grub command line "grub rescue>" 10. I tried using the tutorial on Grub2, but... a. It would not understand the command "linux" b. When I try to do insmod, it says it doesn't recognize the file system.
A few days ago I installed my first Linux product, which is Debian 6.0, and I installed the GRUB booting device on my main boot record, as it was suggested that it was a harmless step to take. Unfortunately, some quirk in my system made GRUB believe that I had XP when in fact I have Vista, so the options I have now are to boot Debian or to boot XP which is not on my computer. In other words, I have to get rid of GRUB now, but I'm realizing that he's not such an easy customer to kick out. I have moved my Linux installation to another drive, but the old GRUB always stays in place, and my Vista is stuck there frozen for eternity. So after considering all kinds of possibilities, I have come to the conclusion that the easiest way to restore my original boot record would probably be to find its backup copy that I assume the installation program made, and to copy it back into the right address at the beginning of the disk. I don't have the Vista recovery CD, so I really have to do this manually. So now my questions are these: did the installation program make a copy of the boot track, and if so, where did he put it and under what name, and finally, what command can I use from within the Debian terminal, which is now my only tool left, to copy the content of thesaid file into the first 512 bytes of the hard drive? I know that would be a simple matter for any serious geek, I guess I must be a little rusty. Anybody feel up to it?
I have an old Dell Dimension 4500 that, until recently, had 2 hard drives. One drive is running Xubuntu Koala and the other was running XP. I had set up Xubuntu to run LVM.
After needing XP again for a small project I tried reinstalling XP, got disk errors, took the drive out to just have Xubuntu, and now when I boot I get "Error loading operating system".
I have tried restoring GRUB from a Live CD with no help. Everyplace I look on the net talks about restoring GRUB after installing Windows on another drive. I'm trying to get GRUB working again after removing the XP drive.
I have installed Windows 7 on my laptop . Now, it directly boot from Windows 7 . I think the MBR overwrote my grub . I have found two methods by google , but still does work . 1: boot from debian install CD, Alt +F2 switch to the console. "grub " "root (hd0,0)" "setup (hd0,0)". 2:boot from CD, mount /dev/scsi/host0/bus0/target0/lun0/part1 /mnt ; chroot /mnt ; grub-install /dev/sda.
My friend recently re-installed WinXP on his laptop, but I'm having trouble getting Grub2 working. I followed a guide online, but when I booted it back up again, I got a Grub prompt instead of a boot menu.
I decided it was time to reinstall Windows 7 because it became increasingly slow. I know that there's a different solution to solve this problem, but as a user I'm just more satisfied with the noob friendliness of Windows. However, I know that it has its drawbacks so I had a dual boot setup with Wubi (30GB). My old configuration was as follows:
C: partition of size ~80GB with Windows 7 x64 installed D: partition of size ~400GB with data and a wubi ubuntu at D:/ubuntu
So what I did was this:
- Backup all my personal files and D:/ubuntu on a external hdd - Wipe the partitions using the windows installer - Create a C: of 100GB and a D: of 380GB - install windows 7 x64 on the C: partition
Now I would like to restore my backup of the old D:/ubuntu to a working dual boot system. I realize I may have missed some opportunities and the data may be gone, but I only found out about that when it was too late. I have tried installing wubi, and replacing the new ubuntu folder with the old one, but this did not work.
error: no such device: 9054698454696DC2 error: no such disk
I have also tried replacing only the root.disk file, with the same result. I searched for other people's solutions, but they did not seem to work in my case.
I had an older PC on which I had two SATA drives and an IDE one and on the latter I had Windows 7 installed (I kept it on that drive since I'm not using Windows 7 that often, I'm primarily using Debian as my daily go-to OS), but since then I got a new PC which has no connectivity for IDE, so I had to decommision the drive, and before I did that, I backed up the Windows 7 partition (and the second partition which I used mostly for storing sofware and stuff that I wouldn't want to get wiped after a fresh Windows install) using dd.
Not reading up on this on the internet, doing so with the intention to restore the partition image on the same spot on the disk, but since the SSD is larger than the IDE drive, I made the partitions on it bigger, so there's no chance the Windows 7 partition to be on the same spot on the disk. I tried booting into Windows 7 from GRUB after it successfully detected the Win7 install on the second partition on the SSD, but it just leaves me with a blank screen with a blinking white cursor, so I'm guessing it's not going to fly again. So my question to you: is it possible to ressurect the Windows 7 installation, avoiding having to reinstall Windows? (which would severly complicate things, having to backup and wipe the Debian install I have on the first partition...)
So far I've tried this to fix the Windows 7 install by pointing at the right disk "coordinates": [URL] ...., but I can't seem to get it to work, all I get is some error in regards to not being able to detect the disk's geometry (I think it was the number heads I couldn't figure out to input in the command line), so I couldn't fix it.
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 do not know what to do, i cannot load windows partition. it just loads grub again. this must have been something that happened when i upgraded to the 10.04 or w/e. can someoen help me out with what i can do to stop this or fix it. maybe i can reinstall but i want to know what will work first, i do not have a lot of time to fool with my computer like this again. i spent a week getting ubuntu on my computer the first time so i do not ever want to spend that much time again especially in finals week. !
I am actually facing a vague problem here. I was previously running Windows XP and Ubuntu . Ubuntu was installed Windows XP The problem is
1. First I tried to do some disk partitioning. That ended up with some error.
2. Ignoring that, I went to install Windows 7 over Windows XP but I was not able to proceed with Windows 7 , because the partitions were corrupted.
3. So I used Ubuntu LIVE CD (Grub was lost at this point )and used 'testdisk' and recovered the partitions.
4. Now installed the Windows 7 successfully.
5. Now again I moved to Ubuntu Live CD to write the GRUB. After which I tried restarting
6. Now Ubuntu is booting perfectly as before. But the problem is with Windows
7. The GRUB loader instead of showing Windows 7, it shows Windows XP !!! . and there is no other entry for windows. When I tried opening it, it says "error, cant read file" and further inout moves back to the grub loader list again.
"How do I change the entry to Windows 7 from Windows XP and boot Windows7 successfully " I tried it a couple of times, same thing happens . So how to change the entry?
I had 9.10 installed and I did an upgrade to 10.04. However I cannot see anymore my Windows Vista partition with grub.. I have a Toshiba laptop Satellite p305.This is my boot script output:

I'm having some trouble removing unr from my asus eee pc 1005peb, I installed it about a month ago and sadly to say I need cash so I will be selling the eee pc. I want to restore it to factory settings. I already tried uninstalling unr, by deleting the partition it was on, that didn't work. Once I booted up again it gave me a grub error. So I reinstalled unr and now have a left over swap partition from the original install. I want the system to boot up as it did before the installation of unr. How would I go about doing this?
I know i get the error code because i dont have my windows partition. But i seriously need my vista back. I tried using VMware player but it didn't work. Is there anyway i can restore my windows partition without the installation disc? The restore disc does not work as it needs a windows partition.
