How do I recover my accidentally lost Windows partitions after installing Ubuntu?


How can I recover a Windows XP drive partition lost after uninstalling Ubuntu?

I have a Windows XP (SP2) desktop with 4 partitions C:14 GB ; D: 14 GB ;E: 55 GB; F: 55 GB; (approximate size).

I had installed Ubuntu 10.04 by creating space for it using existing disk partition (as guided by the installer).

Two new partitions were created by the installer (one with 10GB and the other 500MB) which didn’t have any name like Windows partitions (ex: c,d,e,f).
So, in the disk management, I could see two unnamed partitions and 4 Windows partitions (C,D,E,F). Using Dual Boot I was able to use both Windows and Ubuntu.

Recently I wanted to uninstall Ubuntu , so followed steps given in the Internet.

As guided, I went to Disk Management, right clicked on the first unnamed partition (which belonged to Ubuntu) and then clicked “Delete Volume”.

According to the tutorial only that particular partition should have been deleted.
But both my E and F...

So, long story short, while I was installing Ubuntu I selected my windows partition for the Linux "swap" and now the hard drive is inaccessable. From what I've read, I know it's pretty much reformatted and the only way I can restore it is to use testdisk.

Anyway, I've analyzed my disks on testdisk and I'm not entirely sure where to go from here. I just want to remove the swap and change it restore it back to windows and try to recover what files I can. Any advice would be appreciated. Thanks.

I had Ubuntu and Windows installed on this 480Gb drive (on my laptop) and decided I'd like to try Linux Mint.

One of the options given in the Linux Mint installation Wizard was to delete Ubuntu 15.04 and install Linux Mint in its place.

During the installation, an error occurred and I had to hard restart my laptop. Turning it back on revealed that something was wrong. Booting up Mint from the same USB again showed that the drive now only had 3 partitions.

Fat32 - 512Mb - boot ext4 - 438.74Gb linux-swap - 7.89Gb

Nothing inside the ext4 partition was from my Windows install.

Did the installation really delete my Windows partition (it seems so)? Did I go about installing Mint incorrectly? And how could I go about recovering any data from my Windows partition (I had nothing on the Ubuntu...

Why need to reinstall Windows?

Why and when do we need to reinstall Windows system? Here the following, we'll list you some reasons why and when do we need to reinstall Windows. You would go to reinstall Windows due to these reasons:

Windows system files or boot files are deleted or corrupted; Windows registry has been corrupted; Hardware failure causes Windows system crash; Fail to remove the virus/spyware; A fresh Windows installation; Windows system upgrades or updates; Other unknown reasons which cause Windows system unbootable.

How to recover lost files/data after reinstalling Windows?

When you are in the process of reinstalling Windows system, you may suddenly remember some important files are in the "My Document", system partition or on the desktop. After Windows reinstalled, you only find these important files have been lost.

Usually when you reinstall Windows, 'Documents and Settings' folder will be reinitialized while the files in that folder...

If the screen shot you’ve posted accurately represents your current disk state, then I’m afraid you’ve trashed your Windows installation. If so, it will be very difficult to completely recover it at best, and probably impossible, unless you have a recent backup. I suggest you check out:

The first two of those links point to questions and answers on this site relating to data recovery. The remaining three provide information on the Extensible Firmware Interface (EFI) and its 2.x variant, the Unified EFI (UEFI), which is the type of firmware your computer has. When you re-install Windows, and eventually Ubuntu, it’s important that you understand EFI issues, since you ran into a mixed-mode problem (as described in the final linked page) on your first attempt, and you made the wrong choice. That wrong choice (to force an EFI-mode install) wasn’t the key cause of your problem, but if you hadn’t wiped your Windows partitions, it would have created another (lesser) type of mess...

What Is System Reinstallation

System reinstallation refers to format system partition (usually partition C), and then copy new system into it. When reinstalling operating system, user can choose clean installation or upgrade installation. Definitions are as follows:

Clean installation refers to install another operating system beyond previous operating system, namely, to format the whole hard drive and then reinstall system. Process of clean installation should be: data backup -> format hard drive -> reinstall system -> reinstall applications -> copy data back. Upgrade installation refers to upgrade previous operating system, for example, upgrade Windows 7 to Windows 10 which bears advantages of retaining original programs, data, settings. However, compatible problems may arise and it's difficult to downgrade.

Yet, though Windows update could bring us many benefits, it may also lead to troubles. The Windows update will delete our files sometimes; what’s...

Please help me:

I have a HP TX2000 Pavilion

It had Vista with a WD 320GB HD.

I tried installing ubuntu but sadly it did not work properly, then I thought to increase the partition but by doing so I deleted my original Vista and lost all my work.

I tried booting up PC but it did not work, I tried using system recovery disc but it did not work.

The laptop now just turns on and goes to a prompt screen where you cant type anything.

I took the HD out of the laptop and installed it in a SATA to USB case and tried accessing the information from my windows 8.1 Dell laptop, but all I can see is 2 drives : 1st for 235mb and the 2nd for 12GB... I cant see where the other 300 odd GB has gone and I cant see any of my files.

Can anyone please help? I've got all my personal stuff on the laptop.

After the overwhelming feeling of dread passed, I started to look into file recovery options. I demoed a variety of commercial products to see if any of them could find my lost files or partitions. Nothing seemed to work. Finally, I discovered TestDisk and PhotoRec, and was able to use the latter to recover my lost files.

TestDisk can recover lost partitions of virtually any filesystem. PhotoRec can recover files of most types, including most picture and video formats. PhotoRec can be used on existing partitions, or can be used to recover files on deleted partitions without having to recover the underlying partitions. Both PhotoRec and TestDisk can be run on DOS, Windows (9x, NT, 2000, XP, 2003), Linux, FreeBSD, NetBSD, OpenBSD, Sun Solaris, and Mac OS X, and, their developers claim, can be compiled and run on most Unix systems.

The recovery

I began my attempt at recovery by using TestDisk run from a Knoppix CD. Unfortunately, I had...

I used testdisk to try to recover some files lost while copying them. I was copying folders each containing a movie and its description as a txt file usually. I was copying them into another directory on the same disk. Something went wrong and I suddenly had lost almost all the content of the larger directory and I had deleted the other directories using shift del.

I made the recovery (as much as I could have hoped for) but the files (movies and all the txt files or any other recovered files were all marked with an x in the upper right hand corner and also most had a padlock image on them.

Of course I knew I had to run testdisk as sudo, but I was now faced with how to deal with the files it copied to another drive and how to unprotect them or be able to read them or use them in any way.

How do I do that? I seem to have most I lost but see no way to use the files it recovered. I remember using a windows recover program many years ago that didnt have such a...

This is a strange article for me to write as I am normally in a position where I would advocate installing Ubuntu and getting rid of Windows.

What makes writing this article today doubly strange is that I am choosing to write it on the day that Windows 7 mainstream support comes to an end.

So why am I writing this now?

I have been asked on so many occasions now how to remove Ubuntu from a dual booting Windows 7 or a dual booting Windows 8 system and it just makes sense to write the article.

I spent the Christmas period looking through the comments that people have left on articles and it is time to write the posts that are missing and update some of those that have become old and need attention.

I am going to spend the rest of January doing just that. This is the first step. If you have Windows 7 dual booting with Ubuntu and you want Windows 7 back without restoring to factory settings follow this guide. (Note there is a...

Are you seeking a way to recover lost partition? Don’t know which way is reliable? Follow us to read this article and find the best solution here.

In one of the following situations, partition loss can happen:

• Wrong deletion: this can happen often. You are managing partitions on a drive, and you want to delete one the many partitions on the drive. However, you delete another one by mistake.
• Clean on the wrong disk: in command prompt, you think you are clean the right disk, but you are clean another one in fact.
• Partition table is corrupt: due to improper operations or virus/malware attack, partition table may get corrupted and leads to partition loss.
• Power surges: if power outage happens while the partition is still being read/write accessed, a partition may get corrupt and then lost.
• Hard drive issues: one or more hardware issues may lead to some corruption in a partition, leading to partition loss then.
• Bad sectors: if...

Unfortunately it seems you accidentally partitioned your whole drive replacing your Windows partitions with a single Ubuntu partition.

You will not be able to recover these partitions by restoring Vista with the recovery CD. In fact every write attempt to your hard drive will make things worse as remnants of your data may get more and more overwritten.

Encrypted partitions can not be recovered

You may however be able to recover your partitions with testdisk but you may not be able to recover all of your data. You can temporarily install testdisk on a live session too (however this will then not be a permanent installation).

Please have an external drive ready to save your recovered data before you proceed. You can't recover the data on the same drive.

Boot your Ubuntu LiveCD ("Try Ubuntu") and then install testdisk by:

After Looking at your RESULTS.txt file, I realized that after toasting your installation of Linux, it appears you accidentally also took out (killed) your Windows boot loader and quite possibly big chunks of your Windows installation.

I agree with Jim Five; I also really hope you backed up your data files. I always recommend backing things up to an external Hard Disk Drive (Preferably as large as you can afford and that is available, and using USB 3.0, even if your system only supports USB 2.0 currently).

I would use someone else’s computer to create a bootable thumb-drive, using either YUMI - Multiboot USB Creator | USB Pen Drive Linux or Create bootable USB drives the easy way (Rufus, whcih is for Windows computers, but you can load other non-WIndows ISOs onto the thumb-drive, but only one ISO per thumb-drive); or you can install and use UNetbootin - Homepage and Downloads. I prefer YUMI first, UNetbootin second, and Rufus last.

So use YUMI. It’s the best....

This question already has an answer here:

I had a serious problem during my Ubuntu 14.04 installation. I had a Windows 7 partition and a separate partition to install Ubuntu, where I already had Ubuntu 12.04 installed.

During the Ubuntu installation, I was asked if I wanted to either "Upgrade Ubuntu" or install it fresh new. When I chose to install it (which would delete the existing Linux installation along with all its files), I thought it would delete files only on the existing linux partition. However, for my surprise, it deleted all the existing partitions and created a single one for the new Linux install.

I had some backup of my data, but some very important documents were lost due to this repartitioning and formatting of my hard drive.

I know that there was a way to avoid this during installation, but it did not seem very intuitive to me. In previous versions it was easier to install Ubuntu alongside with Windows without risking all my...

I had Ubuntu and Windows 7 installed, but since I never used Ubuntu and it used 130GB of space I decided to delete it. I deleted two partitions and completely wiped the one with the data. The other one - which I believe had the startup - wasn't wiped. By the way, my CD drive doesn't work.

At first I got "error: no such partition" in GRUB. Eventually I managed to put the Windows Recovery Disk on a USB stick and made it bootable using PowerISO. Windows Repair couldn't fix the problem automatically.

I then read some forums and asked somewhere else and they said to download GParted and put that on a USB stick, boot from it, and edit my partitions there. I downloaded GParted and tried to set it up the same exact way I got Windows Repair to work (with PowerISO), but it didn't work.

I formatted it as FAT, FAT32 and NTFS (but exFAT didn't work, that's the only one I haven't tried). I tried a program they recommended called Tuxboot, too, but that didn't work. I always...

You will need to make changes in grub loader ..

Its declared that you have not included Windows os entry in grub loader while installing Linux.

Always keep it in mind .. if you want to dual boot linux and windows.

always install windows first and include windows entry in boot loader while installing linux..

because they both have different boot loaders and overwrites each other boot loader.

Windows Boot loader has no provision to add another os in the list whereas Linux has the provision to add another os in the boot loader list .

You can save your Windows OS as it is possible to re configure the linux’s boot loader .. and reset the windows boot loader.

Follow these steps if you want to save windows OS:

Restore Deleted Partition?

In most of scenarios, to restore deleted partition you need to do following:

Scan Hard Disk to find deleted partition, and if it’s found then Select partition you want to recover and run Restore Partition dialog. You may scan this partition first to verify its content

You cannot restore partition if it’s overlapped existing partitions on a disk.

Only four primary partitions can exist on a same Hard Disk – you cannot restore partition if this amount exceeds.

Step 1: Scan Hard Disk for deleted partitions

If partition was deleted the space on disk becomes “Unallocated”. You can scan this space to find deleted partition and retrieve data from it or even restore it back.

You can try to find deleted partition even if this partition has been overwritten by another partition and still have a good chances to recover your data from it. In this case, you have to select Hard Disk to scan.

Step 2: Select partition...
