Ubuntu Installation :: Dual-boot With Windows 7 - Retrieve Deleted OS Files?
Feb 23, 2011
I recently tried to install Ubuntu 10.10 on to my Windows 7 computer so that I could dual-boot it. I didn't want to mess about with partitioning and the lot so I just clicked Install inside Windows, assuming that it would install it and I wouldn't have to do anything. But after it installed I noticed that it had deleted all of my files and my Windows OS. I am wondering whether there is a way that I could retrieve my files, or if somebody could post some instructions so that this doesn't happen again.

I had Ubuntu/Windows 7 dual boot. I decided not to use Windows anymore, so I deleted it's partition (using Gparted) and formatted it to ext4. Then I did update of grub.Here are few issues I am having now:
1. The new partition won't automount
2. I can not use new partition. It has only one directory - lost and found. I can't copy data there.
3. Grub still has Windows 7 option (it doesn't work of course)
4. Grub fails to boot (it says it didn't find /windows partition), so I have to always skip that manually

To install Ubuntu alongside Windows 7, I have to shrink Windows 7 partition C:. But due to some unmovable files, I cannot shrink as much as I plan by using Windows own shrinking tool. I guess many of you who have both OSes on the same hard drive must have similar experience.

i am running ubuntu 10.10 on an aspire 5734z laptop, as 11.04 has a backlight issue, and i am dual booting with win7, which i am currently on. i have/had KDE, xfce, desktop edition ubuntu, and gnome 3 sessions installed. i had noticed recently that startup is taking longer than usual, 2x the time as win7, ubuntu and windows are both 32 bit bytheway. after grub, it would be a black screen with only '_' displayed, followed by a screen that says something about sql stuff. i figured this could be the reason my startups were long, and as i dont use sql (that i know of) i decided to just remove it and hope that would fix the problem... yeah, im a linux-noob. i went to software center, searched for it and removed the first entry, and it said it would remove some other stuff, mostly sql named things, plus shotwell and evolution, which i also dont use. after it went thru applying changes, i selected the next one on the list for removal, and the software center froze.
i logged out of the gnome3 part, and logged into ubuntu desktop edition. i then only saw a wallpaper, both of the default panels were gone. at this point i decided a reset was in order. i logged back into the default ubuntu desktop edition part, and the panels were still missing. i figured i would login to gnome3 or kde and see if i could get something figured out from there, but they are missing from the drop down box. the only ones remaining are ubuntu (desktop, recovery and safemode) and xcfe. i logged into xcfe only to find out firefox is gone. i am not familiar with xcfe, i only added it to maybe use sometime when i need to extend battery time, and with no click here to get online - icon in the panel, i figured my best bet was to return to windows and plead for help, before i tried to 'fix' something else, and made an even bigger mess. i dont know what i couldve done to basically render my ubuntu useless to me, to get rid of my panels, firefox, and i dont even know what else.. but the only thing i did at all was to remove the top sql entry, which was something like sql3_lib or something like that.

I got an old Sony Vaio from a friend & wanted to keep a stripped down version of windows along side 10.04. During installation when I saw two Windows partitions. I saved the first one which was about 5 gig & deleted the other bigger partition & used ext4 on the free space for Ubuntu. I assume I only kept the recovery partition so basically I have sda1 (recovery partition)ntfs & the rest ext4. If I pick Windows from the grub menu at start-up the recovery starts but then shuts down with an error. I'm assuming its looking for the other ntfs partition to install & can't find it but I'm not sure what to do. I haven't done anything with Ubuntu yet so deleting & reinstalling is not a problem but if I do getting back to the restore menu probably will be. I don't have any disks that came with the computer either.

I just did an upgrade from 9.10 to 10.04 and now I can't boot into Windows 7 on this dual boot desktop. I usually do a clean install but with a laptop and desktop a copy of Windows 7 and Ubuntu on each machine it's getting very tiring with 4 os's so opted for the upgrade this time.
During the installation there was a window that game up about upgrading grub and what devices to install it on. The help box was not very complete and seemed to say to click all the check boxes which included the main drive and it's partitions including windows. During the install somewhere it said something like grub could not be installed on one of the devices which I think was sda6 which is probably the Windows 7 partition.
So how would I get the option of booting into Windows 7 on startup as now I only get a blank black screen when I click on the Windows 7 option upon bootup? I hope I don't have to reinstall one or both os's again from scratch as this is becoming to much work to do on two systems every 6 months, especially with the amount of programs I have installed.

Just go myself a new computer and thinking of how set it up. I have win7 HP and will probably install at least some version of Ubuntu on it shortly to have dual boot. Might come other Linux distros too in the future. I have a 1TB HDD and my question is what's the smartest way to share files on all OS's? In what format?
I was thinking of ~100GB for Windows for apps and games etc. ~20-50GB for Ubuntu and some third partition, where I store my common files like media, pics, docs, downloads and stuff, taking the rest of the free space.
What filesystem should the shared partition be? Is there some smart way to get windows home directories and linux home directories to point to the same place on the shared partition or would it be recommended to just keep them separated?

I had a dual boot machine with fedora 12 and windows vista and I could use grub boot-loader to switch between two. Few days ago windows got corrupt and I have to reinstall it. I put windows 7 now and as usual it erased grub. So to reinstall I put the fedora 12 installation CD on and followed some usual setup steps. When I got the command line I issued the command "grub-install /dev/sda" (sda not hda because It showed bunch of sda, sda1..) but surprisingly it said grub command not found. I remember doing it before while it worked fine.

I still have my bios problem that about very 3 boot I have to re-flush the Bios (have dual bios). Whilst this is a workaround ...it is @#$%.
The question is: Does the OS write any thing into the bios? And does the bios interrogates the running system and makes assumptions for the next reboot.? Some files on the USB stick can't be deleted. Even with root permission. I reformatted the usb stick.

I have a netbook running Windows XP as standard. There is also a recovery partition which came from the factory.
In the past I installed Ubuntu (I think 9.something) from USB key and all worked fine. However my XP became corrupted and I needed to do a repair on it. After this, Ubuntu became removed from the boot select menu.
Since then, Ubuntu has become updated to 10.04, which I now cannot install.
The Live CD tells me there is a "file IO error" and simply stops installation at around 70%.
I did manage to get into Ubuntu from a Live USB using Wubi. However when I chose to install Ubuntu to a Harddrive, the option to "install side by side" was missing.
After reading on the forums, I did a chkdsk /f on Windows and tried again. Now my liveUSB does not show a boot menu!
When I select to boot from USB stick, the screen goes blank with a flashing cursor. Ctrl+alt+dlt reboots.
I'm really lost here! It seems when I fix one problem, another problem arises!
Also when trying to instal Ubuntu within Windows, the process goes through to 100% and asks me to reboot. When I do so, the option for Ubuntu does show in the boot menu. However when I select it, I get an error "Windows boot failed: file wubildr.mbr and status: 0xc00000f - something is corrupt".

I have Ubuntu 10.04 LTS and Windows XP installed on my laptop. Usually when booting, I get the GRUB 2 menu and I can boot into either Ubuntu or XP.I was playing around with EasyBCD, then after trying to remove it I was unable to boot into Windows, I used a Windows 2000 CD recovery console to fix the MBR (using: fixboot and fixmbr).Now Windows starts up when I power on, but I don't get the grub menu anymore with an Ubuntu option. If I boot from the Ubuntu Live CD and try to mount my Ubuntu partition (/dev/sda5) I get this error:
mount: wrong fs type, bad option, bad superblock on /dev/sda5,
missing codepage or helper program, or other error
In some cases useful info is found in syslog - try

I have just installed Ubuntu 10.4 x64 onto a machine with Vista Ultimate x64. When I boot the machine, the Windows option comes up in the GRUB menu. However, when I attempt to boot Windows, I receive the following error: No such device: de80ab9f80ab7d21. error: No such partition. Press any key to continue...
I looked around and found a similar issue at [URL] However, before trying to fix the issue by guesswork or via solutions that worked for a similar, though not necessarily identical problem. I've run the boot info script (see output below) mentioned several places on this site as a valuable input for boot problem tracking. how to get Windows to boot on my computer?

I'm trying to dual boot Win7 and Ubuntu WITHOUT using Grub. This is to support Bitlocker encryption.
I followed this guide, and now when I select Ubuntu I get a Grub> prompt and no ubuntu.
I feel like I'm halfway there, I just need to get Grub to load correctly or something.

I am trying to install Ubuntu on a machine that already has Windows 7 on one partition. Obviously I intend to install it on the other free partition. So I downloaded the iso burnt it onto the disk and pop in the disk and the boot the machine. The installation screen comes up I selected the first option (Try Ubuntu without installation), I just see a prompt after a few seconds and then the screen goes blank and nothing happens. Unable to detect a signal, The monitor goes into standby. The same thing happens if I use "install Ubuntu" option as well. I downloaded minimal install version Ubuntu and tried to install with that. since its old school installation, the installation completed without any errors, but when I restart the grub come up and when I select to boot into Ubuntu, I see the same behavior i.e. the screen goes blank and never boots to anything. This is a machine on which I was using 10.4 until yesterday.

I just got a Toshiba Mini NB305-310 and tried to install Ubuntu 10.04 on it using the .iso file on a flash drive. When I try to boot into Windows XP, the loading screen comes up for a second, flashes blue, then restarts the computer. I'm able to boot up in Ubuntu, but it takes a LONG time with the screen black before it goes to the Ubuntu loading screen. I saw in an earlier post that it's helpful to post the output of the Boot Info Script, so I've posted it below. I'm new to the forums, so if I'm doing anything wrong, please let me know:

I am trying to run a dual boot system with Windows 7 and an Ubuntu 9.10 installation from a live CD. I am running this on a Dell Inspiron M5030. Both operating systems have installed fine however whenever I run Windows the computer subsequently fails to run Grub upon rebooting and gives the following error message:
Grub loading
the symbol 'ob_bioslgrub?+E?U? Not found
Aborted press any key to exit
The unrecognised symbols are different each time. I have also had (' ') and ('ee*??S ') and ('un'). I cured this initially by reinstalling Ubuntu but after looking at the support documentation have now found that I can cure it temporarily by simply reinstalling Grub using the command:
sudo grub-setup -d /media/dd5d6cd6-cb80-40e0-baf3-13ae1ebe17a4/boot/grub -m /media/dd5d6cd6-cb80-40e0-baf3-13ae1ebe17a4/boot/grub/device.map /dev/sda
I can then run Ubuntu fine, however upon running Windows again the problem reoccurs and Grub will not run.

I just set up a dual boot on a system with fedora 12 and XP. XP in on one hard drive (sda) and Fedora on a second hard drive (sdb).
I installed grub on the Fedora disk so as to not touch the windows disk at all.
Prior to installation, in the bios, I set the Fedora disk (sdb) first in the boot sequence, and then XP (sda) so that the grub loader would boot up by default. (If I set the windows drive first then the system bypasses grub and loads straight into windows.)
My system can now boot up into Fedora fine, but if I select windows from the grub loader menu I just get a blinking cursor - windows will not boot.What do I have to do so that grub can boot into XP?

I have a 160 GB hard disk with three partitions (All NTFS):
C: (30 GB) (WINDOWS XP system partition)
D: (60 GB)
E: (60 GB)
I want to install Ubuntu on another drive (D: in this case). I have backed up all my data on D: drive. What are the steps in doing so and does Ubuntu support NTFS? If it does then will I be able to read and move data between all the drives without any problem (while running either of operating systems)?

I tried to set up a dual boot system on two separate hard drives. I installed Windows XP first (because doing so in past experience has made it easier) on the PATA 20 GB hard drive configured as slave on the first IDE channel. Then I installed Ubuntu 9.10 on the PATA 80 GB hard drive configured as master on the first IDE channel along with an NTFS partition on this drive:

I can't for the life of me get my GRUB whatever version I have to dual boot these. I've spent over 3 weeks on it and then finally gave up.
But It would be really nice since I have so much software that is solely devoted to windows. Not to mention with my photography stuff it's just a whole lot easier to run everything through windows. But for the general census I do prefer Linux.
I'm running these two operating systems. (although I can't access my Windows 7 because of the boot menu problem) I think that's all that needs fixed but I'm not sure.
Ubuntu 9.10 ( I believe it's 64bit although the "about" doesn't specify) Windows 7 64bit is installed. Currently I only have access to Ubuntu.

I have ubuntu 9.10 installed and working on a Pangolin Performance system 76 laptop with a 120 gb hard drive. The ubuntu install has 65 GB free at the end of hard drive (done using Fdisk). It is STATA II hard drive. I got a dual boot to work on a upgrade for an HP desktop for my mom so I know the basics. Using the windows 7 OEM home premium I go the first steps i.e. time ect. Then it shows partitions (as 4 seperat objects 1 primary and 3 logical). The 2nd and 3rd are swap and more ubuntu space. The free space also comes up as logical and is the 4th partition. I try to install and says can not use this partition on the hard drive.I press the format and in changes to extention but still gives the same error (error log is not viewable in the install). All a can do is press a formate button in the install no menu. I formatted as NTFS in gparted and it still would not work. I saw posts about bios and XP but they were old.

For a couple of years I have wanted to use a version of Linux rather than Windows. I currently use XP and regard myself as a reasonably experienced Windows user. My current system has two SATA HDDs - roughly 500Gb, the 'D' drive, and 140Gb, the 'C' drive, and I have 1Gb RAM. So I decided to try Ubuntu 9.10. I downloaded the installation file, created the disk and ran it live for a time. Then I decided to take the plunge and install properly.
I created free space on the C drive, around 17 Gb, in which to install ubuntu. The installation into 'the highest amount of free space' seemed to go well but when I rebooted I was given no opportunity to select Ubuntu - it booted straight into XP. So I tried again. This time I chose to 'install them side by side'. Again the installation went well but again, on the reboot, the system went straight into XP. I guess I must be missing something - can anyone tell me how to install so that I can boot to either XP or Ubuntu?

i am trying to dual boot 10.04 with windows.
Windows works fine and i have 200g of unallocated space for ubuntu.
When i boot from my burned iso image i get the following error
(this is not word for word) "The disk has encountered an in-recoverable error.
restart your computer or try the installation again".
Note: I have tried re-burning to a different DVD still the same thing,
Also just to test it out i successfully upgraded from 9.10 to 10.04. But i want a clean install not a upgrade.
