• Can not copy files after installing windows

  - by Ali

  I am experiencing a weird problem. I was running Xubuntu on my laptop until yesterday that I had to delete Xubuntu and install Windows. I had a NTFS partition on my Xubuntu that I kept some files on it. Today after installing windows I wanted to move all the files from that partition to an external HDD. I selected all files and folders and clicked on Copy, then I went to the HDD and clicked on paste but nothing happened. I can not do that. I do not know why. I copy the files, and wherever I click paste, nothing happens. If I try to copy the files and folders one by one, I can copy some of them, but some of them do not move. The other problem I have is that I can not open some files, in particular pdf files. When I click on pdf files I get this error: There was an error opening this document. This file cannot be found. Also, I cannot play some mp4 files. I can not open some jpg and txt files. I get this error The directory name is invalid. So in summary, after removing Xubuntu and installing windows 7 I have the following problems with one of the NTFS partitions on my internal drive: Can not copy or cut all folders and files from that partition to any other partition - I also do not get any errors. Can copy some folders and files Can not access some pdf, jpeg, txt and mp4 files and get the above errors. I should also mention I did not change anything for this partition during the installation or formatting the other partitions.

• Software Raid 10 on VirtualBox?

  - by user791022

  I want to learn how to use Software Raid 10, is it possible to use VirtualBox by adding four storage images? This is my plan: 4x 100mb partitions (1 on each drive) configured as a raid 1 for /boot in ext3. Then with the remaining space on each drive, setup a software raid partition and configure it to to LVM and raid 10. In the LVM, set up a 4gb swap partition and the remaining space as the root partition ( / ) as ext3.

• Free NTFS partition recovery

  - by Andrei Tanasescu

  I have a 1Tb disk which was partitioned into a ~700gb ntfs disk and a 300gb HFS+ (mac os X). I've accidentally allowed mac os x to wipe the hard-disk and create a single HFS+ partition over the hard-drive. I want to recover my NTFS partition. TestDisk fails to find the NTFS partition, but the DiskInternals solution does find my files. Are there any free alternatives to DIskInternals Partition recovery solution? THe tool should simply go block by block and attempt to reconstruct the files.

• VirtualBox: using physical partition as virtual drive

  - by Hamman Samuel

  Background: I am using VirtualBox installed on Windows 7. From within VirtualBox I am using Xubuntu as a virtual OS. The reason I chose this approach is so that I don't have to keep turning off Windows and rebooting from Xubuntu every time I needed to switch OSes. And VirtualBox's seamless mode is pretty amazing to allow me see Xubuntu and Windows 7 all in one screen. Issue: Now I am thinking of a way to have Xubuntu more integrated into my system. By this I mean I want to have a physical partition for Xubuntu. But I want to still have the feeling of the seamless mode. Question: So finally, my question is: is it possible to load a partition in VirtualBox as a virtual OS? Case examples: Ideal scenario would be: I physically boot up and login to Windows 7. Now I want to access Xubuntu, so I load VirtualBox and access my Xubuntu partition without rebooting. And the other way around too, i.e. I boot up the system, login to Xubuntu, and can access the actual Windows 7 partition through VirtualBox. Other info: Please note that I am not talking about getting access to files, as I have a completely separate partition for my files, and am very familiar with VirtualBox's Shared Folders option.

• Borked ubuntu uninstall - need to delete boot partition (i think)

  - by Max Williams

  I just got a new pc laptop with windows 7 and wanted to install Ubuntu on it. Which i did, no problem there, by downloading the installer, burning it to dvd then booting off the dvd and installing. Then, i realised that the new Ubuntu 12.04 uses the Unity desktop, which i immediately disliked, and after some research, began to hate. So, i decided (after a little googling) to install Linux Mint instead. So, thinking i'd better start from scratch, i went to the Windows 7 disk manager and wiped the Ubuntu partition that had been created. Now, when i start up, i get an error from grub, the ubuntu boot manager: error: unknown filesystem grub rescue> _ and a blinking cursor where i can enter commands. I suspect that what i've done is deleted the main ubuntu partition but NOT deleted another partition which is a boot partition, or something like that? Can anyone tell me how i can rescue or unbork this? I'd like to either a) get back to my original windows-only setup OR b) install linux mint off dvd (which i have), into the empty partition, fixing any grub confusion in the process. Any suggestions? Thanks, max BTW please don't answer if you're just going to tell me to stick with 12.04, or install a different distro or something. I definitely want Mint and just want to fix this mess - thanks :)

• Resizing Windows 7 bootcamp partition

  - by Charlie

  I've installed Windows 7 on my Mac using bootcamp but stupidly only allocated it 25gb which isn't enough once I've installed Visual Studio and other stuff. I was able to shrink the Mac partition using whatever tool it is in Mac OS Snow Leopard but it wouldn't let me increase the windows partition so I rebooted into Windows to try it but am still having problems: I coudn't extend it using the disk management tool because the option is greyed out so I tried diskpart.exe but when I use the extend command with my partition selected it says: Virtual Disk Service error: There is not enough usable space for this operation. I've got 19.69gb of unallocated space though so am not sure why I'm having the problem. I don't want to have to wipe my Windows partition, any ideas?

So far I have tried to ¨fixboot¨ and ¨chkdsk¨ from a recovery console on the affected windows partition (/dev/sda1), the plug off power cord for 15 seconds trick, reinstalling GRUB, repairing the MFT and boot sector of the affected partition via testdisk, what next please ? Thank you!

• 2 HDs in RAID 1 with 2 partitions ?

  - by Prix

  Hi, i am not very familiar with raid partitons and am not even sure if this is the right place to ask about it, but i hope that if it is not that some one can point me on the right direction. This is my situation, i have 2 500 GB hds and a 3ware pci-e hardware for raid and i wanted to make a RAID 1 but i dont know if i can make more then one partition for it, for instance: MAIN HD: os partition: 100GB data partition: rest of left size and make the RAID 1 either work on all the HD or just on the data partition of it. that is on windows xp sp3 and the 3ware allows bootable raid.

• System reserved

  - by arun sidharth

  I have a HP laptop. I upgraded to windows 7 ultimate from home basic. Now I'm trying to upgrade to Windows 8 but when I do I get a message saying not enough system partition. So I opened the disk manager and increased the size of system reserved partition and it was of no use I still got the same error. Then I unfortunately deleted the 100MB system reserved partition by right clicking it and clicking format in the disk manager! Now I am not able to boot any CD's from the startup including OS and recovery CD. Whenever I press esc it always goes to the login screen and it doesn't say anything about the boot from CD option. Now I could not even use my recovery CD. I have 3 questions: Is it necesseary to create a system reserved partition if so how to create it? How to use my recovery cd How to install win 8

• Encrypted partitions with redundancy on ubuntu server

  - by Flamewires

  Hey I have to make a file system with an encrypted partition with on ubuntu server. something like Unencrypted: / - 10 GB /home - 10GB /var - 5GB -------------- Encrypted: /opt - 50GB This I can figure out in the setup, just partition as normal, setup /tmp as a encrypted volume with dm-crypt. However im not sure how to mirror this entire drive, so that if either failed i could still boot. and how will that affect the encrypted partition. Any help would be appreciated.

• Recover Partition-Table still present in running system

  - by theomega

  Hy, I accidentially overwrote the first 1M of my harddisk on linux (using dd). So, the partition-table is gone. I can still access all partition (except the first one) using /dev/sda2 (and so on), so the data is still there. I only need the partition boundaries to restore the table. How can I do this? The Linux-Kernel must still know them because all mount-points still work. fdisk -l /dev/sda doesn't work because it acctualy reads the partition table. Thanks!

• Will deleting partitions affect my hard drive in any way?

  - by Portali5t

  I installed a Suse partition of around 200 Gigabytes on my hard drive, primarily running Windows 7. I am sick of Suse's crap, and just want to get rid of the OS and get that partition back for Windows' use. Is it as simple as that partition gets deleted,and I can choose what partition that space goes to, or is it communal that all partitions can access? I know next to nothing about partitions, so any help would be great. Also, if someone knows HOW to delete partitions, that would be a great help too. Thanks!

• Linux cannot alter partition table of main hard disk of my laptop

  - by djechelon

  I run openSUSE 12.2 on my ASUS N76VZ laptop. My problem is that I cannot alter the partition table of first hard disk /dev/sda1. YaST partitioner says it's unreadable, but actually it can read it but not alter it. It doesn't tell me anything else, except that I can wipe the partition table (having to reinstall Windows for the third time). Since I want to create new partitions on that disk, how do I fix the partition table layout? I could create new partition from Windows Computer Management and format them in Linux. I could do this, but it doesn't explain the problem

• Is there a filesystem that is "friendly" to both windows and Linux?

  - by Somebody still uses you MS-DOS

  I'm planning to install Ubuntu 10.04 with Windows 7. (I'm new to Linux, have to use at work so I'm planning to install it at home to learn more) I plan to use a partition to my Windows system files (C:), a partition for my personal files that already exists (D:) and a new partition for Linux. What I want is to have a partition for my personal files that works across these systems - so, if I start with Windows or Linux, there's the same "Videos", "Pictures", "Projects" folders. Is it possible? Is there a hd filesystem capable of having writes from both systems without too much risk of corrupting or something?

I've read some horror stories of corruption, and would like to know from a sysadmin POV all the risks involved in such scenario.

• Resizing 2 partitions (NTFS and ReiserFS3)

  - by steven

  When creating a Win7 and Gentoo setup I miss allocated the space needed for Windows and Linux. I have a 320 gb drive and created a 40gb partition on Win7 and used the rest of the space on Linux. Now I need about 70gbs on the NTFS partition. Are there any tools that will shrink the ReiserFS3 partition? (It is using about 80gbs and has the reset free), while growing the NTFS partition? If I have to clone, does the tool copy freespace inside the image? I would prefer this not happen as that I'm sort on backup space. [I can handle a 100-150gb of images, but I can't copy the entire HD]

• TrueCrypt partition will no longer mount

  - by sparkyuiop

  I am hoping for some advice to help me out of my situation, with luck. I have a computer running Windows 7 Ultimate x64 with 3 hard disks installed. On my 2TB hard disk 2 (non-system disk) I have 4 partitions. One is for music, another for video, a downloads partition and a 500GB RAW Truecrypt encrypted partition / volume that I had setup to mount with 4 photographs used as keyfiles. The 4 photographs are located in my 'Documents' partition which is one of four partitions on my 1.5TB hard disk 1 (non-system disk) When I setup the disk encryption I did not (I'm 99% sure) create a password, I only used the 4 photograph keyfiles to mount the volume. Recently my 1TB hard disk 0 (system / boot) started to fail so I decided to replace it. I was going to clone the old disk to a new disk but decided that a fresh installation would be more beneficial. Once I had transferred all the required 'User Data' from my old hard disk 0 (C: disk) I discarded it. I reinstalled Truecrypt, pointed to the partition, selected my 4 keyfiles photographs and I mounted my encrypted volume with no issues. In fact I mounted it several times after re-installing Windows and after reboots. Now all of a sudden when I try and mount it I get the message "incorrect keyfile(s) and/or password or not a Truecrypt volume". Now I am not sure why this happened as I do not recall exactly what I did between last mounting the volume successfully and it not mounting. Here are some of the possible things I may have done to cause it to stop working but I am at a loss as to where to start to try and resolve the problem. 1. I had swapped the drive letters to a preferred order. 2. I possibly swapped the physical SATA connectors on the mainboard. 3. I enabled 'Hot Plugging' for the two non-system hard disk SATA ports and the DVD SATA port in the BIOS. I have tried changing the encrypted partition drive letter as suggested in another post but this does not help. On my old system the encrypted drive was drive "X". I have about tried it with all the other free drive letters but alas nothing changes. I do not recall what drive letter was allocated to the encrypted partition before I changed them all. I have not tried to change the letter back to what it possibly was to start with as I am happy with the current layout. I will try this is anyone thinks it would be worthwhile though. I do hope I have managed to convey my situation in an understandable manner and live in hope someone could help me recover years of personal files. Thank you very much for taking the time to read my post and for any suggestions you may offer. Regards Phillip Thorne (UK) Anyone???

• windows 8 recovery partition

  - by Rafik Takieddin

  Recently I have bought a second hand HP Notebook from a friend. The PC still has the recovery partition not backed up yet. However, I'm thinking of resetting Windows using the new Windows 8 resetting feature. Windows warned me that all files will be deleted. Is it okay to reset Windows then backup the recovery partition in order to have a fresh backup or this can lead to losing the recovery partition and, with it, my genuine copy of Windows 8?

• How to un-partition a drive on windows 7

  - by Michael Rentmeister

  I bought this laptop used from a friend. The laptop has 500gb of storage; however, the drive is partioned. The C: drive has an allocated space of 50gb whereas the partition has 396gb allocated to it. How do i either take some of the space from the partition and move it to the C: drive, or get rid of the partition? I've done some searching and people say I'm supposed to be able to use "Disc Management" to "delete volume," but when i right click on the partition the "delete volume" is not enabled. Here is a picture:

• Boot from Recovery partition in Sony Vaio Laptop with no imagex

  I have visited more and more pages in internet and read lots of solutions but no one solved my problem. I have my 10 GB win7 recovery partition in my Hard Disk but when I press the F10 button it was not booted from this partition (I use this method to recover my laptop several times recently). So How can I boot from my recovery partition? I copied the partition into a flash drive and tried to boot from usb but it does not take effect. I think if there is a way to recover the F10 button functionality, I can recover my laptop.

• How to recover Windows 7 partition?

  - by user1018733

  I created a 50GB partition on my hard drive to experiment with installing a 2nd copy of W7. (I wanted to see if a clean install would fix a bug) However, It seems I can no longer access the old part of my computer the way it was before. I was under the impression that creating a partition like this was harmless. Is there anyway to change my primary partition back to what the computer boots to? Thanks
