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've got a, as it seems to me, strange problem.I've inadvertently deleted my user from the group admin so I'm in the same situation of a lot of other users (read a lot of messages about it).My problem is that when restarted in recovery mode there is no way I can choose the 'drop to the root shell' or similar in the menu.The menu appears for a second and then I've got an empty screen. If I press a key I've been requested for a username and password that of course is not what I need.

I'm about to install Ubuntu Netbook Remix and my Acer machine has a recovery partition at the beginning of the drive. I've created the eRecovery discs but those will only restore XP - not the actual recovery partition (which I'd like to have in case I sell the laptop later etc).
How can I backup the actual recovery partition, and keep its boot file intact. Then how can I restore this partition at a later time?

I have just bought a new computer and I want to partition it to be dual booting as I have done a few times in the past.
Currently (alternatively, see attached screenshot):
There are three partitions:
/dev/sda1: FAT16 DellUtility (takes very little space and is of no concern)
/dev/sda2: ntfs RECOVERY (takes up 17.58GB and is marked boot)
/dev/sda3: ntfs OS (the rest of the computer, on which windows is currently installed)
[Code].....
it is safe to delete the current boot partition. I am also not quite clear on when the recovery partition would be used and whether it is really all that necessary (18GB doing nothing seems like a lot to me). Should I make a system recovery media for windows before repartitioning? Also, I am not sure which type of ext partition to use. Finally, I am not sure how big to make the swap space. I think I recall the normal rule being twice the RAM (6GB RAM in my case), but 12GB swap space seems like a lot. Although I do sometimes run memory intensive programs (simulations for research). I normally use other computers for such simulations since they have far more RAM than my computer can possibly have even with a large swap space.

I have an issue with my keyboard not being picked up in Ubuntu and I went to go ahead and boot into the factory recovery partition to start from scratch, but after it gives me a ramdisk loading bar, then goes to a black screen with a mouse like the recovery will start, then the computer just restarts. Now, I can boot into Ubuntu (but no keyboard) and boot into XP (as I am now) but I can't get the recovery partition to boot.My current station is out in timbuctu, so I am awaiting the arrival of a flash drive to load a LiveCD onto to use Gparted for any potential solutions.

I was installing 10.10 x64 today. I wanted to manually partition the disks, since I have a /home partition from a 9.10 installation which I want to keep.Unfortunately, I selected to convert the ext3 /home partition to ext4 and didn't realise it was formatting the partition until it had just begun. In desperation, I pulled the power plug, but now I can't access the partition (using the LiveCD) - comes with an input/output error.What are some strategies to recover the data on the partly formatted partition? I don't think much, if any, was actually formatted.

I'm having an issue installing Ubuntu with Windows 7 Home Premium 64-bit through Wubi. The Wubi installation works great and Ubuntu seems to install after the first reboot after selecting Ubuntu from Windows' boot menu, however whenever I select Ubuntu from Windows' boot menu after Ubuntu installs and it reboots for the second time, it loads the GRUB bootloader, however Ubuntu isn't listed at all.
Windows 7 is listed twice and Windows Vista is listed (seems it picks up the recovery partition for Windows 7 as Vista) and when I select the first Windows 7 from the GRUB bootloader, it just goes back to Windows' boot menu with Windows 7 and Ubuntu as the selections. If I select the second Windows 7 from the GRUB bootloader, it'll boot Windows 7 like normally. It looks like Ubuntu is nowhere to be found. Because of that, I just ended up uninstalling it.

I'm thinking of buying an Acer Aspire D250 loaded with Win7 and then adding a version of Ubuntu.
The netbook will come with the Acer recovery facility to reinstall Win7 from a recovery partition in the event of OS failure. This means that the MBR and subsequent loaders need to be preserved for this function to remain (I don't have a Win7 disc and don't want to have to buy one).
I'm happy with a basic Win/Linux dual boot setup but I'd value any comments/suggestions as to how to preserve the recovery function when I add Ubuntu.

I would like to build an oem style install partions that is bootable with menu to choose if I want to run install or boot already installed system. I would like to include current source packages on the same dive so if I don't have internet access at time of install, can can still install what I need.I know with Windows Vista and Windows 7, you can get this but how can I do this with Debian?

I have a Lenovo thinkpad T400 with Vista x64 that I want to dual-boot with fedora 10. The T400's original config has 3 primary partions:
1) Vista boot partition (some weird partition that it only uses to boot... this is my first time using Vista so I don't know the details, but I think it has to be there and it has to be a separate partition from the "data" partition)
2) Vista data partition
3) Lenovo Rescue and Recovery partition (a separate bootable partition that is used for recovery, backups, ...)
My first attempt was to shrink the recovery partition and add a new extended partition that has the two standard fedora logical volumes and an extra NTFS to be shared between the OS's (I usually use FAT32 for this one, but NTFS support seems to be pretty solid now).
Everything was fine, but I couldn't boot into the rescue partition. According to this site:
[URL]
You *have* to have a linux boot partition be your primary partition. Other people have told me the same thing and that site has an explanation, but I don't get it =)
So, it seems that I need 5 primaries (3 original vista/lenovo primaries, 1 linux primaray to put the boot stuff into, and 1 extended for everything else) to make this work (which is not possible). Can anyone think of something else I could do (other than getting rid of Vista and the Lenovo stuff and giving them both the finger?) I'm thinking maybe I could make an extended partition and move one or more of the Vista/Lenovo partitions in there, but I'm not sure if they could boot.

The problem is, on a machine, you can only have 4 primary partitions. sda1 and sda2 are my Vista and Recovery partitions respectively, which eliminates two of my primary partitions already. I myself have never used logical partitions, and was wondering if any of the partitions the Beginner's Guide recommends (/, swap, /var, and /home) could be made logical, and if I even need a swap partition.

I'll start by admitting I'm bad at backing things up. My situation is that I have a desktop that was in storage for a year, and I don't have the login name or password anymore. Is there anyway to get around this roadblock, say by upgrading? I'd really like to save the files on the HD.If I can boot up in protected mode and login as root,it seems that I should be able to change the login and pwd.

I was a regular Windows user and have installed Ubuntu 10.04 LTS 2 days back. Not really sure what was my mistake during installation but that had erased all my data. I lost windows completely and lost all my data in all 4 drives including drives itself.I searched in internet and forums as how could I recover my data, and got solution to use test disk. Testdisk worked perfectly, I recovered my 4 drives and retrieved data for 2 of my drives. But I still cann't retrive my important data from other drives.I guess data still exists in hard disk. (no free space , and no data)I know there could be several threads which had solved this kind of problem.

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 wanted to experiment with Fedora 14.
The machine has Windows XP and Ubuntu 9.10.
Before today when I turned the machine on there was a black screen with many Linux kernels to choose from and Windows.
I created another for Fedora and installed it on there - the Ubuntu root partition is still there.
When I boot now, there is a blue Fedora screen with just it and Windows.
To make matters worse Fedora doesn't work with my graphics card (Matrox). I would like to get Fedora working but still want to have the ability to use Ubuntu again.
What do I need to change to be able to boot into Ubuntu again and how do I do it?

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.

As it says in the title I need to use the scalpel file recovery tool, or something similar to be able to recover a lost mysql storage folder.. The system crashed, and I really need these files as fast as possible. So I would love any help I could get.I have been searching in different search engines (including this forum) for an answer to my question, but I can't seem to find it.How can I configure scalpel, or any other similar application to be able to recover my mysql /var/lib/mysql storage directory. I really need these files... And.. I know, I should have taken backup

I just installed Fedora on my pc with windows XP pre-installed (dual boot). I had the same setup with ubuntu before with no problems. My ntfs windows partition is of 15 gb approximately and the remaining space that was available for fedora was about 220 GB (non partitioned - I removed all the partitions excepting the windows one using gparted from liveCD prior to beginning installation) ..........after installation etc etc.....my home folder shows me only 150GB of space.....what's happening? Where has all the remaining space gone to?

I'm sure someone can help me with this. I have a machine that refuses to boot from USB (including USB CD-Drive) and I have exhausted all other sane options to install Ubuntu on the box.o, my first (in)sane idea would be to create an install partition as an image file, containing all the files needed to install. I could then partition the drive, slap the install partition on the drive, put it back into the computer, and install from the actual system.

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 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

I have a dual boot setup with Windows 7 and Ubuntu. Lately Windows 7 has been causing me all kinds of grief and I decided that it would be better to just restore it back to factory settings. I have a Windows 7 recovery partition (hidden) that I can see from Ubuntu, however Grub2 does not detect it. It only has two identical Windows entries that take me into Windows (though in /boot/grub/grub.cfg they point to hd0,msdos1 and hd0,msdos2 respectively).
I have searched far and wide on the Internet on how to gain access to this recovery partition to no avail. I even found a link from Lenovo's website that details how to do this in the old version of Grub, though it doesn't work in Grub2.
Here are the most useful links that I have found thus far, both fall short unfortunately. [URL]
I have already backed up all my data, so I can nuke the whole disk if that's what it takes, but I don't actually have a Windows Recovery CD, only the hidden partition which I can't seem to boot into.
I also saw some posts where people were having trouble disabling the recovery partitions from appearing in the Grub menu, their answers often consisted of people telling them that it's not possible to disable the recovery partition from appearing without hiding the main Windows Install, oh the irony!

As a big supporter of Ubuntu, after installing Ubuntu 10.10 on my mums laptop i decided to also install it on my sisters Acer Aspire one netbook.
The specific netbook had pre-installed Win7 starter. Everything went really smooth with the installation with ubuntu 10.10, Grub menu was also loading pretty well but when i chose to load on windows it loads the recovery partition of the hard drive.
The issue is that the netbook, like most netbooks and laptops, has a hidden partition which is used to recover Windows on the system. My Grub2 loader added this partition as an option to load windows with result me not be able to boot on windows ...well i do can load but it loads the recovery of windows.
