Ubuntu :: Restore Access To Thinkpad Rescue And Recovery Partition?
Jan 7, 2010
I have a brand new Lenovo Thinkpad T400. Lenovo claims that it should boot into recovery mode if the blue 'ThinkVantage' button is pressed during boot. However, this does not happen after I have installed Ubuntu (Koala). First of all, nothing happens when I press the blue button, and no recovery partition is visible in GRUB boot menu. However, the partition itself is still there. The question is how to boot from it?
I found some tips from [URL], however, they are for GRUB, but my Ubuntu comes with GRUB2. I tried to adapt their instructions to my case. I added this to /etc/grub.d/40_custom:
Code:
menuentry "Rescue and Recovery" {
insmod ntfs
set root=(hd0,3)
[Code].....
That, however results in message about bootmgr missing at startup.
One option would be to start Windows and reinstall Windows MBR, but this would nuke my GRUB, and things could quickly go downhill from there as I am using full disc encryption for my Ubuntu partitions.

is there a way to create a system restore disk or recovery partition ? somewhat like windows has. I do back up my files regularly but a back up of entire os system and settings would be handy.running ubuntu 10.10

I have a sony vaio netbook and installed ubuntu on it some months ago After some weeks windows 7 crashed and stopped booting I tried to recover it but still no success. When i bought it it had one partition only (plus the first one for windows recovery) When I installed ubuntu I partitioned my hard drive at my pleasure as you can see in attached image When I try to recover windows 7 it says it "can't find the windows partition or it's too small" Since 80 gb is not too small, i bet it can't recognized the partition anymore. Can anybody suggest a way to let it recognize my sda2 ? Does it have to have the "C:" label or "Windows something"? (I can only name it C without colons) Does it have to formatted FAT in a particular way ?

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 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.

Two days ago I repartitioned my laptop HD and added the latest Ubuntu (2.6.35-25-generic) to the existing Vista and existing Ubuntu (2.6.32-28-generic via upgrades from 9.14(?)). Prior to this install it was using Grub with menu.lst from the old/upgrade Ubuntu. After the install the boot menu labels the partition with Vista as the Windows Recovery partition and the recovery partition item is no longer present.
At first I wondered how I could get Vista to boot. I found that SuperGrub cd would boot it OK. Then, it dawned on me that the boot menu item was not the recovery partition, but instead the Vista OS partition mislabelled . Vista loads just fine from it. The recovery partition is no longer listed as it was with Grub/menu.lst. SuperGrub will not boot the recovery partition, showing an error "missing BOOTMGR".
'os-prober' produces--
root@Toshiba:/home/deh# os-prober
/dev/sda2:Windows Recovery Environment (loader):Windows:chain
/dev/sda7:Ubuntu 10.04.2 LTS (10.04):Ubuntu:linux
[code]...
I edited boot/grub/grub.cfg so the boot menu item is labelled correctly, but suspect that it will revert back when there is an upgrade.

I tried installing Ubuntu 10.04 LTS on my girlfriend's lenovo using a live disc. First we tried it out to show her the wireless would work fine (her previous lenovo was not ubuntu friendly at all). She's interested in keeping her windows 7 partition along with the lenovo recovery partition, so I tried doing a dual boot install. I manually moved the cursors setting the disk space on each partition, and we allowed Ubuntu to do the rest. Much to my dismay, the installation failed.
I've done some reading over the internet, and I think in our case it would be best to use a Wubi installation. We're interested in using 10.04, so where can we find a wubi installer of Ubuntu 10.04?
Also, any ideas why the installation might have failed? The iso was downloaded off the ubuntu main site, and we burned it using infrarecorder.

I have an installation from USB/DVD issue.
Setup:
1. Desktop running WinXP
2. Lenovo S10e netbook running Win7RC1 (just expired.) no DVD drive.
3. 1 DVD by Novell and Lenovo with "SUSE Linux Enterprise Desktop 10 (For recovery select Restore System from the initial Menu.) November 2008"
4. 4GB USB drive. Laptop can boot from it.
Problem:
Need to install the system to the Laptop using the USB drive. Doesn't install.
What I did:
Mostly followed the guide at "Installation without CD - openSUSE.htm" my USB drive is G:
used the HP USB Disk storage format tool to make my USB bootable.
Copied all files from the dvd to the usb drive
Moved G: ooti386loader* to G:
Deleted E: isolinux.bin
Renamed E: isolinux.cfg to E: syslinux.cfg
Downloaded syslinux-3.85.zip from [kernel.org]
Extract syslinux-3.85.zip to c: syslinux
CD'ed to c: syslinuxwin32 directory in a cmd prompt
Ran syslinux -ma E: .....
Result:
Runs all the way through, gets to a windowed program called ">>> Linuxrc v3.0.20 (Kernel 2.6.22.5-31-default) <<<" Code: could not find the openSUSE Repository. Activating manual setup program
Main Menu: Settings, System Information, Kernel Modules (Hardware Drivers), Start installation or System, Verify Installation CD-ROM/DVD, Eject CD, Exit or Reboot, Power off Cant find anything on the usb drive (obviously?) so what do I do now?
This is where I'm at and quite stuck... not sure what other flags there are to use, what I have to move around or rename.

is it possible to use a Windows-based recovery partition on a dual-boot computer to overwrite the Ubuntu partition and remove the GRUB loader? For instance, if you booted up your computer, accessed the hidden recovery partition and used it to reset the computer to it's factory default settings, would that effectively remove the Ubuntu partition and the GRUB loader? Would a completely new installation of Windows overwrite/uninstall Ubuntu and GRUB automatically?

My set up is a dual boot between windows 7 and ubuntu 10.04. This laptop used to have vista on it. See image below for my partition set up. pretty obvious where ubuntu should be.I accidentally selected the wrong entry in grub and booted into an acer windows recovery partition. despite exiting as soon as it loaded, the long story short is that it has goodbyed linux.On booting i now just get a grub rescue prompt.I have eventually managed to boot into a liveUSB (cd drive is botched too )As you can see from the screenpic, testdisk shows linux is still there but there are quite a few entries from the upgrades.So, if i can restore the partition around this linux partition will grub come back with it and will all be merry?
I havent mounted any volumes on the drive yet, but i think i need to back up my data before messing with the partition table. is it cool to mount them to pull some data off?general advice for how to proceed would be great.Im not too hung up on keeping the linux install itself. whats gunna be easier? install into that 16gb space and then re add windows to grub, or try and recover this partition?

I own a Sony Vaio VPCEB3AFM. It came with pre-installed Windows 7 Home Premium 64bit, no disks or anything. The product key is on the back of the laptop. I later installed Ubuntu, as I was beginning to take an interest in the potential of computers and began to explore with different Operating Systems. I installed it along side Windows 7. THEN, me being the dumbass I am, installed BackTrack 5 also. I then called Sony in attempt to restore my computer to factory defaults and just have Windows 7 as my only operating system. I shut my computer down and then hit F10 until the Vaio Rescue shows up. It was in the process of Restoring when it restarted and an error message came up. It reads, Error: No Such Partition Grub Rescue>. I have no idea what to do none of the OS boot up when I start it. I have no disks, I have only Ubuntu on a USB drive which I boot up by changing the BIOS blah blah. But when I do not have it in, the error message occurs.

I know this is a common error, but my situation is a little different than previous threads on this issue and I just want to make sure I get the correct solution.
Basically, I had Ubuntu 10.04 and Windows 7 on my netbook and wanted to try a more lightweight version of Ubuntu. After settling on LXDE for a desktop, I decided to install Lubuntu 10.04. I chose not to install LXDE over regular Ubuntu because I wanted to eventually end up with an Ubuntu distro with either GNOME or LXDE, but not both. So rather than put myself through the hassle of uninstalling all the GNOME or LXDE packages, I decided to keep them each on separate partitions.
In the end I decided to just stick with regular Ubuntu and deleted the Lubuntu partitions. Now I get the GRUB error written in the title of this thread.

I uninstalled ubuntu from my main HDD, and its now on a different HDD. when I turn on my computer I get:
Partition not found
Grub Rescue
I've used my windows disk and repaired my mbr and boot (bootrec /fixmbr bootrec /fix mbr) multiple times, yet I always get this problem.
Only way I can boot windows is if I leave my install disk in my drive. It will say press any key to boot from cd / dvd I just wait a couple seconds, and it boots into windows. Without the disk, I get the grub problem. I have only 1 partition on my HDD, and that is my windows 7 partition, nothing else.

I running a dual boot of 10.4 and windows 7 and was trying to add a free disc space to one of the partitions using gparted and the window 7 tool. On restart I get this DOS-like message:
Code:
Error: file not found.
grub rescue>
From what I have gathered, from other posts I should
1. Go here [URL]
2. Reboot and run ubuntu from the live CD
3. Create a results.txt file
Here is the results data:
Code:
Boot Info Script 0.55 dated February 15th, 2010
Boot Info Summary:
=> Grub 2 is installed in the MBR of /dev/sda and looks on the same drive in partition #5 for /boot/grub.
=> No boot loader is installed in the MBR of /dev/sdc .....

A friend gave me Ubuntu 9-10 and I have been using it in my netbook for some time. Bthe other day we did an update and now a black screen is up and states: Error: no such partition Grub rescue>_ I am operating dual O'S with Windows XP and Ubuntu The only thing I have been able to do after searching hours on the Internet is the following: When I type set it gives me the following information:
Prefix=(hd0,5)/boot/grub
Root=hd0,5
Grub rescue>_
I understand that the hard drive is 0 meaning the only one I have and 5 means the location of the grub in the partition. Other than that I can get no further!

This is my first post on Ubuntu, ive been testing/and dual booted then reverted back to windows this past year, and now have gone back to school for computer networking...so im SUPER interested,So - i want to install Ubuntu on my little Toshiba netbook that i drag everywhere with me, but im afraid to screw with it's partitions. I dont want to spend $$$ to get a larger than 8GB flash drive to create a recovery from the HDD partition that is installed on their, and they dont come with the backup/recovery disks, so i want to either leave that partition alone (in case i need to switch it back to windows down the road to sell it), or whatever.
I know i could just download windows to my PC, transfer the files to a flash drive, and put it on that way, but the recovery comes complete with drivers, etc which makes it a smoother and faster process. Oh, i cant make the recovery of windows b/c i need 7.xx GB of space, and my biggest flash drive is an 8GB which doesnt quite make it.SOOOOO - IF i install Ubuntu, will that recovery partition DEFINITELY be left alone? Or is there an easy way someone could suggest copying that partition without a 16GB drive? OR is there any way to use an external hard drive to copy that recovery partition on to?
I have only installed ubuntu once, maybe twice, but didnt care about partitions and wiped everything as requested by the install. (i reverted back because i couldnt navigate quickly installing and updating programs, but now have a windows laptop and want to be forced to learn linux on my netbook).any help is MUCH appreciated! I have an Ubuntu scratch that im dying to itch, but dont want to lose my windows recovery

I 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.

I am new to ubuntu OS, I am having quiet a hard time solving out certain problems. I have Ubuntu 10.10 and Win Xp installed on the same hard drive partition i.e. C drive. Now yesterday accidentally I deleted a folder from C while I was logged in to Windows. Now today when I restarted my pc I got this error message :
error : No partition found
grub rescue>
Then somehow I managed to reinstall the Grub loader. Now whenever I restart my PC I get this error message :
GNU GRUB version 1.98+20100804-5ubuntu3
Minimal BASH-like line editing is supported. For the first word, TAB lists possible command completions. Anywhere else TAB lists possible device or file completions.

I had 3 partitions on my hard dive, Windows 7, Ubuntu, and just junk on the other. I installed Ubuntu in a way where it went to the GRUB filesystem? first, where it ask me to start in linux kernel 2.38.6 (can't really remember the kernel exact name) which was ubuntu, some other options, recovery mode, and at the very bottom was the one to go to Windows 7. I was in Windows and I wanted to get rid of my junk partition but I formatted the Ubuntu partition by mistake.
Now when it boots up it saying:
Error: unknown filesystem. grub rescue>
I hope there is a way to save my files on Windows. I tried to reinstall Windows 7 back on my computer but it wouldn't go through since the grub startup thing is the main one, not the windows one.

I was copying a bunch of files between hard drives. For some reason I have permissions issues, but I was able to copy the data using cp in the terminal (I know I can sort out permissions, but that's something for another thread).So, I start copying files just fine, but cp doesn't have any sort of progress indication. So, I started up another two terminal windows, cd'd to the source and destination folders, and ls -l'd each to compare the folders.
At this point, I realised that I'd forgot to add -r to the cp command, so cancelled it. I decided it'd be better to start again and add -r in, and repeat the command. So, I went to the folder, went up a level, then rm -r'd the folder I was just in. It wasn't until I'd gone through with the command that I realised I was actually in the source folderSo, putting aside all the obvious things like 'You dope, you shouldn't have been messing around with rm -r, let alone sudo' and 'With great power comes great responsibility' and 'This never would have happened if you'd just sorted out your missions and usedNautilus', is there any way I can recover the data? I know it's possible in ext2, but not in ext3, but it's on an NTFS partition. Is it possible to recover files from this

I'm using dd to clone a Windows Vista hard drive and recovery partition with zero luck. I duplicated the partitions with gparted then used dd to copy each partition and then the master boot record. Nothing............. no boot.
Code:
dd if=/dev/sdb1 of=/dev/sda1
Code:
dd if=/dev/sdb2 of=/dev/sda2
Code:
dd if=/dev/sdb of=/sda bs=512 count=1
