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)

I'm using an Eee netbook so i have no CD drive. I've used Linux for about a week. Someone else installed it for me using their flash drive. If I need to use a flash drive to install I will need info on how to install to a flash drive. I had it set up so i could choose windows or ubuntu at start up. logged into windows to play a game and all it brought up was.
GRUB loading.
error: no such partition
grub rescue>
Now that's all I get when I turn it on.

I got ubuntu 10.04 lucid lynx along with windows (dual boot) and using Grub. On my computer, I have my C:/ (programs) and D:/ (data). I've never used my D:/ before that day that I've lost my windows partition on my grub menu. I usually use my D:/ with windows. The first time I used my D:/ to store data with linux, I lost my windows option in my grub menu. I'm not sure what I did wrong but I do want to restore my windows option in my grub menu.
After "fdisk -l",
I checked in /boot/grub and there is no menu.lst to modify. how I can get back my windows option in my grub menu ?

I was and idiot and stared messing around gparted before I was ready to partition my hard drive. Consequently I messed up my partitions, and when I restarted my computer a screen comes up that reads:
GRUB loading.
error: no such partition
grub rescue> _
Have I killed my computer or is there some way I can fix it?

Ubuntu 10.04 not loading. Sticks at GRUB Loading message.
Read the other threads re OS not loading and GRUB. The talk about code goes over my head.
Local techie says the hardware is good. Tried reloading Ubuntu from CD. Tried loading the unmentionable OS.
Tried using Spotmau Powersuite.

I installed Ext2fsd from windows XP because I needed access to a text file on my ubuntu install. However, it didn't work because the drive is ext4 and all it listed was the root folders (/home, /var etc..) nothing any deeper.
I closed the app and continued working in windows.
Today I went to start my computer and it loaded the grub-rescue> prompt. I immediately tried to run "help" to find out what happened, however, grub reported the command as unknown.
I then ls and got a partial listing of the partitions.
Code:
(hd0) (hd0,5) (hd0,1) (fd0)
So what do I do? How do I recover my linux partition? If the partition is bad - then how is the bios able to find the grub-rescue> prompt?

We had a drive failure on /dev/sda. Everything 'except' boot was on raid5 across sda, sdb, sdc, sdd. I know how to repartition a new drive and rebuild the raid etc, but I don't know how to regenerate the files that reside on the boot partition. I really don't want to re-install as we have lot of custom code and software that may depend on our current libraries and build environment.

When I try and boot my Debian computer I get the messages: Grub Loading stage1.5. Grub loading, please wait... Error 15 Is there any way of recovering from this - or is it simply a fresh install? I was attempting an upgrade from Lenny to Squeeze and despite a few hurdles it looked like it was all happening. Got the new kernel loading, and the new grub. It looked as though grub2 was working so I ran the grub-remove-legacy-support command (something like that) and now my computer won't boot grub or Linux.
I'm assuming the MBR on my harddrive is lost, however I don't know what state the partition is in. I'm guessing that maybe this has been lost as well. I tried a few tools from the Ultimate Boot CD but nothing here was able to re-install my grub or boot from any partition or even mount my file-system. I'm fearing the worst but would like it confirmed before I blow it all away with a new install.

I am trying to set-up a home server using Ubuntu 9.10 server edition. My PC has 4 x 500Gb SATA drives which I will use for storage. I also have a 80Gb IDE drive which I want to install OS on. During installation the 80Gb IDE drive shows as sde. When doing the install I chose to install to whole disk (sde), all appears to go well. When I reboot all I get is "GRUB loading, please wait.... Error 15" Is the problem caused by my drive being sde and not sda? I have also tried partitioning sde as /. /boot and swap, still get Error 15.

I'm getting a funny error after trying to add a new internal hard drive to my computer. After adding the new drive to the "Slave" slot GRUB will not load properly and gives me the following error Grub Loading, Please Wait Error 17 I've checked in my BIOS and the "Master" drive is still the one where grub is loaded. When I unplug the new drive the problem disappears and I can load Grub normally. I've searched the threads, but couldn't find a similar problem, or a problem that could be applied to mine. I've also tried loading the live CD, but my internal CD drive is broken, and the external one I have doesn't seem to recognized during boot time.

I am new to Linux. I have installed RHEL 5.4 on my PC with preloaded Windows XP.
Windows was set as the first boot kernel. So if i do not choose which OS to be loaded it will load Windows by Default.
Today I got an error saying GRub Loading Stage2 read error.

I'm triple booting (windows, ubuntu and osx86) at the moment but in order to load OSX86, I need to pass "cpus=1" to the kernel otherwise it won't load and the PC just reboots. Can I pass this argument from grub or do I have to install osx to a separate hdd and get grub to load the Darwin bootloader on the second hdd and then pass the argument?

I have a system with 10 drives running Linux software RAID using RAID 6. Today the system stopped responding and needed to be hard power cycled. The filesystem on the RAID (note, not the root filesystem, that's on its own drive) is in tact and the data is still there.
But I noticed during the boot sequence this:
The first part didn't surprise me, it just seemed that a drive dropped out. No big deal, RAID is designed to handle just that. But that last bit concerned me. I didn't like the term "capacity change" on my RAID.
As I said before, the filesystem is fine. No change from before:
But /proc/mdstat says this:
Notice the [10/9]. I've seen it say [9/10] when a drive mistakenly dropped out before. And after re-syncing it went back to [10/10] as expected. But does this mean something different? Is there something else that needs to be done besides just letting this finish? Has the RAID somehow changed its shape in some way?

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.

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!

I having a problem getting my grub loader to see one of my hard drives. I added a drive, and my grub loader lost track of where everything was. I couldn't get my old linux (Red Hat 9) so I installed SuSe on my new hard drive. But I need my be able to boot from my old hard drive because it has apps that only run on the earlier version. From /proc/partitions the old hard drive is sdd

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.

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?

I realise that this is not a pure Linux Q, but I am hoping for tolerance and even help!After removing the partitions (/,/home) that held an older Linux installation, gparted showed the original Windows XP partition followed by the new unallocated space. On rebooting, there was a Grub rescue error (text not noted, sorry). A live install running gparted shows a totally empty disk!
The removed OS was booted via Grub2 and I imagine that it is choking when there is no secondary(?) file to be found since it was vaped. I also imagine that this is a fairly straight-forward matter, something like replacing the MBR but I am so far from Windows these days that I am unsure how to progress with rescuing the partition. The machine has no floppy - that's how I would have initially booted it way back when. Is this something that I can do either through a Linux live distro or via a Windows CD?

I have tried to automate the configuration of a usb drive with not much success.
The problem that I have is that I have a large amount of usb drives that have a partition table of type "loop" and I need to change them to "msdos". The size of the drives vary and I need to use FAT32 or FAT16 file system.
I've tried various partitioning commands and gui applications but cant find one that I can give a one line command to to set the partition table, maximum partition size and file system.

My Server runs "fine", then I type init 6 for rebooting or some cron job initiates Init 6 and my system stops in grub at: GRUB loading stage1.5. Error 18 After another Ctrl+Alt+Del the system boots as if anything happened. this is why I doubt that it's an issue of too big HDD or BIOS.

So I have 2 ide hdds but whenever they are both connected, grub gets stuck at GRUB loading stage 1.5. how can I resolve this problem?
both are Maxtors with ext4 fs. primary is 20 gb and secondary 80 gb.
Jumpers are set to cable select.
Boot order in bios is correct. (primary first, secondary isn't in the list at all)
