General :: Installed Win7 With Ubuntu 10.04 - Grub Lost

Jun 21, 2010

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?

General :: Partition Lost After Win7 Installed

Jul 28, 2011

I have a PC, with 1 HD of 500GB and the following partitions:
Windows XP - NTFS 50 GB
Windows 7 - NTFS 350 GB
Linux Ubuntu - 98 GB
Linux swap - 2GB

The last OS that I have installed was Windows 7, and each time, when I started up my PC, I saw GRUB first, and after choosing the option to load windows, the Windows loader giving me 2 options, one for Windows 7 and one for Windows XP. I didn't like to see first GRUB and after that the windows loader, it was redundant, but everything was working well. One day, I decided to mix the windows 7 and the windows XP partitions (deleting the windows XP and resizing windows 7). I tried to do that with the Windows 7 utility included in the control panel but I couldn't. It said that I couldn't delete the active partition or something like that. It was not possible to delete the partition in which WinXP was stored.

Then, I decided to boot with Ubuntu and use the partitioning tool that comes with it to delete the WinXP partition. It was possible to delete the partition, and I also putted the option "bootable" on the 350GB Windows 7 partition. After that, I rebooted and it was not possible to load windows. Then I tried changing in GRUB the entry for Windows, because I thought if I could put the correct partition to load from, it wouldn't be more problems. I tried several times but I couldn't load windows, so I putted the Windows 7 DVD and I started the installation process, waiting to see an option saying that there was already a system in the partition of 350GB, and allowing me to fix the mbr in that partition.

My surprise was when I choose the partition of 350GB and the installation process began. I was afraid of to lose my data then I decided to reset the computer! And now, all my 350GB disk is gone! I can't see the partition when I enter with Ubuntu. I'm really worried about this, because the computer detects the 350GB partition as empty, and I don't know what to do! I turned off the computer and now I am using another to write this. I have all my files and important information in that partition! and It seems it's lost. I hope it's still possible to restore the partition. Actually I don't care if I have to install again my operating systems but I need my information!

Ubuntu Installation :: Installed Alongside Win7 But GRUB Doesn't Appear; Just Boots Win7

Dec 31, 2010

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.

General :: Win7 And Ubuntu 10.1 Installed - Grub Rescue

Dec 13, 2010

I had Windows 7 and Ubuntu 10.1 installed in my intel i3 4gig DDR Sony Vaio E-series laptop. Both operating system were working fine. 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:-

error: unknown filesystem
grub rescue >

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.

General :: Unknown Filesystem, Grub Rescue Mode. Win7, Then Ubuntu Were Installed?

Sep 24, 2010

A few days ago I decided to try a linux OS for the first time. Following a how-to advice, I created a ~80gb partition (on a 320 gb sata disk) for Win7 and installed it. Then I installed Ubuntu 10.04, chose to make partitions manually, created a primary ext4-partition (right after the one with Win7) for / and a 1024mb swap partition. So now the disk is parted this way: 512 booter - Win7 system, ~ 80gb ntfs - Ubuntu /, 8 gb ext4 - Ubuntu 1 gb swap - file storage, ntfs ~240 gb (created using Win7 bootable disk, but the issue from below started before this).

After the installation the boot loader failed to load any system, giving the error from the topic title. I tried several ways to reinstall/repair/reconfigure grub in the live-CD mode. Some of them didn't change anything, others were not completed because of an update-grub error ("cannot find a device for / (is /dev mounted?)"). Grub version is 1.98b. The disk with Win7 and Ubuntu is treated as hd0 in grub and sdd in Ubuntu
ote: even though the thread is marked as SOLVED, the issue is actually not. I have managed to dual-boot Win7 and Ubuntu, but with partition configuration changes

OpenSUSE Install :: 11.4 And Win7 Dual Boot - Grub Lost?

Apr 1, 2011

I am trying to Dual-boot Windows & and OpenSUSE 11.4, and have run into walls all over the place. Here is what I did:

3. Booted into OpenSUSE with no problem
4. Tried booting into Windows, no joy.
5. Got that figured out, now I can get into Windows.

General :: Grub Loading Stage 1.5 Error 21 Win7 / OpenSUSE

Jul 28, 2011

A few days ago I installed openSUSE 11.4 on a 1TB HP external hard drive. I have some very important files for school and personal work on my main hard drive, running windows 7, so I made sure the installation only affected my external hard drive. With the external hard drive plugged in it boots just fine but when it is un-plugged it says Grub loading stage 1.5. Error 21 and it won't do anything. This kind of pisses me off because there were no warnings and nothing was supposed to happen to my main hard drive. But this has already happened and now I want to know if there is any way I could fix it so I can boot windows 7 normally and still boot openSUSE with the external hard drive plugged in.

General :: Upsize Partitions On New HDD - Dual Boot (11.04 On Win7 With Grub)

Aug 12, 2011

I have been an MCSA for the last 20 years, but recently I have been very impressed indeed with Ubuntu 11.04, having dabbled with and then discarded Susi Linux some five years ago. My problem may be summarised as outlined below: Using the downloadable ISO I installed Ubuntu 11.04 as a dual boot on a Win7 100GB HDD on my Lenovo T61 laptop. No problem they both rock and I'm very impressed. During the installation procedure I selected the largest partition sizes available from the Ubuntu installer wizard being 25GB Extended split into 18GB Ext4, and 3.2GB and 3.2 GB swaps (I couldn't suss out any way of manually increasing them any further).

I found that the 11.04 Startup Manager application didn't work at all, so I downloaded and installed Grub Customizer 2.1..and that did work after a fashion.. certainly enough to actually effect changes in the grub configuration settings. Everything worked so well on the 100GB HDD that I decided to transpose the entire disk image to a new 500GB WD Scorpio and make the dual boot my main working disk. Using Acronis I imaged off the 100GB installation selecting the partition by partition, and retain disk signature options. I then recovered the image to the new 500GB HDD and everything works beautifully on the new HDD.

Except of course all the partitions are still the same size. I won't waste your reading time recounting everything that I have done using Acronis Disk Director (V Good) and Gparted (not so good), but needless to say whatever I do Grub won't have it, and I have lost count of the times that I have re-recovered the good image. Basically I want to increase the partion sizes to apportion larger partitions to both Win 7 and 11.04 and obviously I'm missing something somewhere.

Fdisk -l -u produces..
Disk /dev/sda: 500.1 GB, 500107862016 bytes
255 heads, 63 sectors/track, 60801 cylinders, total 976773168 sectors
Units = sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk identifier: 0x9f011ed1 .....

Ubuntu Installation :: Boot/grub/win7 - Testdisk/update-grub Method, But It Didn't Work?

Mar 4, 2011

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.

Boot Info:

Boot Info Script 0.55 dated February 15th, 2010 [code]....

ls: reading directory sda6/: Input/output error

I have tried the testdisk/update-grub method, but it didn't work.

General :: Changing Grub Boot Order And Make Win7 Default

Aug 13, 2010

I recently upgraded to Ubuntu 10.04 from earlier versions. I have a dual boot system with Windows 7. Grub was set to boot Windows by default Things were working fine. I decided to upgrade to Grub2. It seemed like a good idea at the time. Now when booting up,the name at the top of the Grub menu is 1.98, which is Grub 2. When I run grub-install -v, it comes back grub-install (GNU GRUB 0.97) which is not Grub2. Now when I boot up, Ubuntu 10.04 is the default. I have to manually choose Windows if I want to use that system. I have been unable to change the boot order following instructions from this site. Any Way changing the boot order to make Windows 7 the default. I am using a Toshiba Satellite.

General :: Lost Grub - Can't Boot Ubuntu 9.10 ?

Mar 2, 2010

Today I was forced to reformat windoze and of course lost grub so I can't boot ubuntu 9.10. I found two suggestions in previous posts which didn't work. One suggested using the install disk as a rescue disk and as root run grub. I entered sudo grub and the cmd was accepted but the cmnd grub was not found.

The second was to sudo grub -install and again grub was not found. Both these suggestions were for a win 98/mandrake installation.

Do I have to reinstall ubuntu? If so there is a problem in partitioning. Setup sees there is already an ubuntu os on the disk. In fact two of them. I forget why, but I reinstalled ubuntu and ended up with two in the grub menu. I was advised not to try to repair grub and didn't. Now I have two and it thinks I want to put the third one side by side, or erase and use the entire disk. There was a third choice but I forgot already exactly what it was and didn't like it anyway. If I erase and use the entire disk, won't I lose windoze? If I put them side by side I will then have three which which will waste disc space. The discs aren't that big being only about 10gb. I don't think I want to waste the space with a third ubuntu.

General :: Lost Partition - Grub Loading But Can't See LVM Drive

Aug 22, 2010

I've resisted the urge to post for as long as I could. I use these forums quite often in finding answers to the numerous linux questions that I've had & found it to be a great resource. For some reason after an innocent reboot of my Fedora 12 Core system, GRUB decided it would no longer load the O/S. I was just getting a flashing _ in the top left of the screen. I thought there must be a problem with the partition table & have used the systemRescueCd to run testdisk (I have made a copy of the disk first to an image file using dd - don't worry I made sure I got the commands around the correct way!).

testdisk shows that I have a partition which is bootable & Primary, which appears to be the grub partition (I can list the files in test disk). However when I search the disk I get the following after it has found a couple of partitions. (it is an 80Gb disk)

Ubuntu :: 64bit Version Not Installed For Dual Boot With Win7

Oct 29, 2010

So I decided to try something new and fresh. I wanted to try ubuntu. So I download the 64bit version from here. I made a 25GB partition. I then Wubi found out I didn't need the original file since it was downloading something else. I installed it, rebooted.

Windows comes up with a prompt:
Boot from:
Windows 7

I click on Ubuntu. This comes up: [URL]. I am fairly new and I don't know what to do. I did research and nothing really showed. I then burned the said 64bit version and tried to do a Live CD but it didn't reboot into ubuntu. I really want to try ubuntu? I am going to re-install again.
