[ubuntu] Windows partitions lost after installing ubuntu??

http://ubuntuforums.org – Hi, I have two physical hard disks, one around 200GB and one 1TB. I had the large one splitted into 3 partitions around 300GB each. I used Windows XP. Yesterday I formatted the small disk and installed Ubuntu 10.4 (trying not to mess with anything in the large disk). Now from within Ubuntu I can see only the third partition of the large disk (referring as size 1TB). I tried to use GParted but it still mentions only one large partition (that contains only the files of the third previous partition). Any way to recover lost partitions? Thank you very much, Nick (Hardware)

Stories similar to [ubuntu] Windows partitions lost after installing ubuntu??

Hi I had an 70GB ubuntu partition and I installed windows 7 on the rest odf the disk. After the installation the ubuntu partition seemed deleted, I used a live cd and gparted showed that parttion as unallocated space. I found here an old thread saying about TestDisk and how I could copy my lost data. I followed the instruction, installed TestDisk and found my lost ubuntu partition.

Im running Ubuntu 11.10 from the USB stick. I have a 2TB internal HDD which has 2 partitions of 1 TB each. Problem is that Ubuntu here is detecting only one of the two partitions. I cant see the other partition in Gparted or in the 'Disk Utility' App. Its kind of a lost partition which I want to bring back. Please help me detect and mount it. :( I hope all the data on other partition is safe.

I'm trying to figure out how to allocate ~80% of disk space to Ubuntu 12.10 and ~20% to Windows but after installation, it seems like I only have ~177 GB volume on both Ubuntu and Windows when my HDD is 1TB...GParted shows multiple partitions (3 nfts though I understand one is on the SSD?) with one of them being very large but inaccessible and protected(key symbol)?

The GParted application is the GNOME partition editor for creating, reorganizing, and deleting disk partitions.  A disk device can be subdivided into one or more partitions. The gparted application enables you to change the partition organization on a disk device while preserving the contents of the partition.

Hi everyone,

From man fdisk:

Linux needs at least one partition, namely for its root file system. It can use swap files and/or swap partitions, but the latter are more efficient. So, usually one will want a second Linux partition dedicated as swap partition.

I have a Windows 7 computer. This is what I did:

Using Windows Disk Management, shrunk the available hard drive producing a partition more than large enough for Ubuntu. Changed the boot order in BIOS to CD, USB, HDD. Inserted Ubunto 12.04 disk, launched Ubuntu. Chose "Install alongside windows 7". Successfully installed Ubuntu, restarted, and it goes straight to Ubuntu.

Hello there,

First I must say that I feel so stupid, and here is why. I installed Ubuntu on a win7 machine in a different drive than C: - G: partition- and lost all the data contained in G:. Tried to retrieve the data but it looks gone. another partition was wiped as well. When in ubuntu, disks and Gparted show the partitions and I tried to undo the changes, but without success.

I have a dual boot (Windows 7/Ubuntu) system and I recently accidentally formatted a 500GB partition on a 1TB hard disc (see thread "Lost Data after formatting hard disc"). I could not recover the original partition but recovered the important files I had lost. Then I tried to format the partition back to how it was originally (500GB NTFS).

I just bought a new laptop that comes with Windows 7 preinstalled and I want to install Ubuntu alongside with it.

The system came with 5 partitions:

System partition Unknown partition NTFS partition (the one with windows) NTFS partition (to be used for data) A recovery partition

I had removed the NTFS data partition and shrinked the windows partition to make room for Ubuntu as it will be my m
