Since the partition of windows7 (C: ) where wubi was installed was too small, I decided to reinstall wubi into another larger partition (E: ), keeping the old root.disk. Sadly when I replaced the root.disk ubuntu cannot boot, the loader says that there is no root.disk file, although it's there... I guess there is some kind of checksum about the virtual disk toward the loader is poiting... So how can I have my old ubuntu installation back?? I still have the old root.disk.

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 worked everyday during 1.5 years on a Wubi installation of Ubuntu 8.10.
Before quitting my job I have made a simple copy of the root.disk file, thinking I could restore it easily later.
Now I would restore this system on a Virtual Machine (with Virtual Box)
Have you got an idea how i could do this??
(I already tryied to install another wubi on a virtualized Windows 7, the install complete but I can't see ubuntu in the boot loader...)

I wanted to install ubuntu via wubi, but i had to format my partitions (can't do it on wubi ) so i used a crappy program(i don't remember the name) to get rid of Backtrack4 , because i wanted windows kept for my mom.So, that was the sorry, i've ended up with a GRUB error 22, and a Backtrack4 CD stuck in my DVD-rom.So my question is: Can somewone tell me how to fix error 22? (i've seen some methods online, but i obviously can't put a Windows CD in my DVD rom because the Backtrack4 DVD is stuck in there.

I had a bad experience with 9.04 - I installed some recommended system updates, and the updated GRUB killed my installation (which is WUBI), not letting me boot.
I've now installed 10.04, and some updates have come through, one of which is GRUB. So I'm now looking at the "Configuring grub-pc" dialogue box that's popped up, and there's an option to "Continue without installing GRUB?".
What are the risks here? Is my 10.04 WUBI system going to die if I upgrade GRUB again? Or is it going to die if I don't upgrade GRUB?

I installed 9.10 with wubi and lately I had a boot problem with the result is that it boots to a grub prompt. I tried several commands, but no success. I thought I hosed the system. [URL]. Once I copied the new wublidr file over, that did it! Give it a shot, as it works.

I beleive I had version 9.x installed. I upgraded once and everything was fine. I went the upgrade manager again and it found some more upgrades. The upgrade messed with grub. It then told me there were no new upgrades. Then I rebooted and it says
Try (hd0,0): NTFS5
Then the screen clears and there is some text I can't read and then it says command not found. Then it reboots.
Is there a way to fix this?
If not is there a way to recover the files from the disk image file.

Installed Ubuntu 10.04 a week ago or so (using wubi.)Tried to upgrade to 10.10 from within Ubuntu using the update manager.Now the PC will only boot to grub rescue.When booting, this is what i get:error: no such device: cd200414-0606-4d7d-8c08-004e9b5dc92d.grub rescue>Three commands work: ls, set and insmod.The ls command only yields: (hd0)(no partitions like (hd0,1), (hd0,5), etc.)

My Wubi installation of Ubuntu (version 9.10, I think) that I recently installed was working fine at one point, but now it isn['t. I select Ubuntu instead of Windows from the Windows boot loader, but instead of getting the usual menu of different linux versions (I think 2, as I updated it at same point), and Windows, I get the GRUB command prompt instead.I've looked at th2e Wubi Guide (https://wiki.ubuntu.com/WubiGuide), and I've followed the instructions for "How can I access my Wubi install and repair my install if it won't boot?", but that reveals no problems.For the record, I'm fairly new to linux and ubuntu, but I'm good with computers generally. The main operating system on my computer is Windows Vista, but I'm currently typing this from a Live CD of Ubuntu 9.10. The virtual disk (root.disk), is currently mounted as vdisk, as indicated in the Wubi Guide.
Ideally I would like to get Ubuntu to load as it used to (with a menu). However, if there is a way to boot from the GRUB command line that would be good too. I'm not at all familiar with GRUB, and the commands I've tried (boot and linux, I think), get errors saying no kernel specified, or loaded, or something like that.

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 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:
Code:

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 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'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?

So, I converted a Vista user by enticing her with WUBI. She's a computer idiot, and she thinks Linux is great.
HOWEVER, she recently had Ubuntu muck up for her, so she uninstalled WUBI/Ubuntu and reinstalled it (9.10). Upon restart, GRUB presented no boot menu and went straight into Ubuntu. The funny thing is, under the GRUB configuration files, the timeout for the boot menu is set to 10. I tried the following (made sure to change the boot device to hda1,0 since fdisk shows her NTFS as /dev/sdb1):
[URL]
No luck. No boot menu, no Windows option. I also tried the following:
Manual Windows Entry (with /etc/grub.d/30_os-prober made unexecutable)
Code:
#! /bin/sh -e
echo "Adding Windows 43_custom" >&2
menuentry "Windows Vista 43_custom" {
insmod ntfs
[Code]....
Using THIS method, the boot loader did appear, but there was no Windows option. Odd. So, I'm at a blocking point. Yes, I was smart enough to run update-grub Thoughts? My replies may be a bit delayed - she's 2 hours away and I don't have direct access to her computer.

I installed win7 after installing ubuntu, and now grub is gone. I looked around for tutorials, but none of them have worked so far.
So, how do you restore grub in 11.04?
PS
I've heard about grub 2? I'm not sure what the differences are.

Dell Inspiron E1405 - 160 GB drive with 2 partitions - I think only 1 partition was used for windows and ubuntu Used wubi to install 10.04 - both XPP and 10.04 worked fine after repairing the XP install My boyfriend used Referencer (.reflib) in Ubuntu 10.04 to organize and tag about 900 documents. He spent around 9 hours on the project and its VERY IMPORTANT. I am a dumb ***, forgot the project was on the computer and updated to 10.10 via update manager without it backing up. Now I cant boot to XPP or Ubuntu - "error: no such device:", "grub rescue" My main concern is getting the data back. I would rather uninstall WUBI and install Ubuntu on the 2nd partition (wish I would have done this in the first place but 10.04 was my first Ubuntu install and I didn't know any better). I have to get this data back! I have tried the following and cant locate the referencer (.reflib) file or the .docs and .jpgs booted to USB using my 10.10 netbook remix USB install USB stick - I can see the windows files pulled the HD out and connected it to my Ubuntu netbook, an XPH and W7 computers -cant locate data
