Restore the partition table data

• Desperately need help - "the partition table on device sda was unreadable." Erase all data?

  I'm forced to install CentOs on my Macbook using a machine virtual (VMWare, which is what I downloaded my teacher recommended). It's for my first class of operating systems, so bare with me because I don't know anything about operating systems (except about how to use Windows and my Macbook). I am also a daughter, what makes my same technical knowledge that much more rare. However, I am eager to learn...

  In any case, I downloaded them both. When I launch Fusion, I choose the file> New> install Windows or another OS on a virtual machine> continue without disk> click on the button that says 'Operating system installation disc using image file'> then I select the appropriate iso CentOS (CentOS - 5.4 - i386-bin-1of6) file> continue> drop down lists, I choose LINUX as operating system and Red Hat Enterprise Linux 5 as my Version> continue-> finish (no customization settings). It appears the screen of CentOS and I am invited by a text asking me if I want to install in text or graphics mode. (Don't know what to do here, but I select the graph). A bunch of white text scroll a screen of black background, then a blue screen shows up saying: 'Welcome to CentOS' at the top and a gray screen that says "to start testing CD media before installation OK press. Choose Ignore to ignore the media test and launch the installation. "I click on the red button (even once, if it is incorrect, let me know). A few rows of white text on black background (from anaconda... something on a video card...) then a nice graphic display of CentOS which I click NEXT. I then select English as my tongue (twice) and I gives me the message:

  "The partition table on device sda (VMware, VMware Virtual S 20473 MB) was unreadable. To create new partitions, it must be initialized, cauing the loss of all DATA on this drive. This operation will replace all choice on what players to ignore previous installation. You would like to initialize this drive, erasing all THE DATA? »

  I have no idea what to do here. I googled the message and others have been too, but they can talk about some hard file (and I have no idea what it is, and I can't seem to find mine).

  I can't lose what's on my hard drive (my school, music, photos, applications, files etc.). Clicking YES will erase my HD? I'm terribly afraid. I need to get this thing installed so I can do my operating systems class work, but I don't know if I did the installation correctly so far and especially, what to click at this point. Can someone help me out please (I spent 4 hours on this one today. "I have no one else to ask)? Finally, the installation is almost done after this step?

  Any help at all would be so greatly appreciated.

  I do not use Fusion, but I have VMware Workstation on Windows. I went through the same process that you went through. The answer to your question is that when you choose the operating system you install and you choose the option for the installation disc, it creates a virtual hard drive for you, size 20 GB. When they ask you to erase the hard drive, it's clear that virtual you create, not your actual computer hard drive. You can check by looking at the properties of the hard drive on your computer. It's probably 250 GB or 500 GB or something big like this. The CentOS WARNING speaks of a 20 GB hard drive, which is the size of the disk that VMware Fusion (and Workstation) create for CentOS.

• after image restore, backup partition table is different

  Hello

  He is a 2012 Macbook mid Pro with El Capitan and Bootcamp.

  After repeated with Bootcamp (Windows 10 Pro) problems I started using Image of Terabyte for Linux in order to safeguard this Macbook. Forums terabyte that people know that the Image of Linux (such as Image for Windows) is able to create a reliable backup, but also to restore - restore an entire disk image or restoring individual partitions.

  I followed their instructions precisely and activated the two options "restore first Beach" and "TPG hidden OS" (as one terabyte official, Member of the forum wrote) when restoring a partition.

  Unfortunately, it did not work! Bootcamp was no longer visible in the start screen or wasn't visible, but not start.

  What I found was that I had to keep the two options (see above) with DISABILITIES.

  Then I could restore some partition images - and 10 Windows in Bootcamp is bootable.

  Well, it was the long introduction.  I'm sorry.

  Now my question is:

  Is this something that has changed my partition table?

  Before restoring an Image for backup of Linux for the first time, I had this partition table:

  localhost: ~ root # fdisk/dev/disk0

  Disk: geometry / dev/disk0: 60801/255/63 [976773168 sectors]

  Signature: 0xAA55

  2: AF 1023 254 63 - 1023 254 63 [409640-857906448] HFS +.

  3: AB 1023 254 63 - 1023 254 63 Boot Darwin [858316088-1269536]

  * 04:07 1023 254 63-1023 254 63 [859586560-117186560] HPFS/QNX / TO THE

  BUT:

  After failed attempts to restore and work finally restore my partition table operation is different:

  Fdisk/dev/disk0

  Disk: geometry / dev/disk0: 60801/255/63 [976773168 sectors]

  Signature: 0xAA55

  From end

  #: cyl hd s - cyl hd s id [Start - size]

  3: AB 1023 0 57 - 1023 255 63 Boot Darwin [858316088-1269536]

  * 04:07 1023 199 8-1023 255 63 [859586560-117186560] HPFS/QNX / TO THE

  Everything seems to work fine, but I wonder if the different appearance of the partition table can be a problem?

  For example, compare:

  1: EA 1023 254 63 - 1023 254 63]

  3 o

  409639]

  1: EA 0 0 2 - 1023 255 [63 3 o 409639]

  In Fdisk, the CHS numbers are arbitrary on modern disks. They are the time of BIOS and old disks with CHS geometry. Puts BCA from Mac 0-1023 (1024 cylinders), 0-255 (256 heads) and 0-63 (64 sectors). Modern disks far exceed those numbers and would drain them. Must match what is the triplet of start/end/size and it fits in GPT and MBR. You can put arbitrary 0,0,0 for CHS and you will see all issues on GPT disks.

• Assistance button works do not (= does ' t start VAIO Care Rescue) after having lost and recover the partition table / MBR

  Hello

  For some reason that I lost my patition table but I was able to get it back and I'm rewriting MBR. I'll be back all my partition and files contain the VAIO recovery partition except files on the operating system partition ("C:\ »). It's an unformatted partition. VAIO Care rescue didn't work so I had to format "C:\". "and reinstall windows 7 and now all is good.

• How to configure the partition table for SSD?

  Drive: 32 GB SSD

  I accidentally delete without backup partition table information and would like to know how to put the partition table, I can access the tools of partition table, but do not know how to define.

  Does anyone have any suggestions?

  Thanks in advance for your suggestions

  Hello

  Thanks for posting your query in Microsoft Community.

  The SSD could be seen in the disk management window, and you could name and set up as another hard drive internal. To create a partition or volume on a hard disk, you must be logged in as an administrator, and there must be unallocated disk space or free space in an extended hard disk partition. To repartition your hard drive, please consult the following link and check if it helps.

  I can I repartition my hard disk?

• Create index partition in the partition table tablespace

  Hello
  
  I am running a work custom that
  
  * Creates a tablespace by day
  * Creates the daily table partition in the created tablespace
  * Removes the days tablepartition X
  * Removes the storage space for this partition of X + 1 day.
  
  The work above works perfectly, but it has problems with the management of the index for these partitioned tables. In the old database (10g - single node), all indexes and partitions exist in a BIG tablespace and when I imported the table creation script in the new database, I changed all the partitions table & index to go in their respective space.
  
  For example:
  
  Table_name... Nom_partition... Index_Part_name... Tablespace_name
  ============...================............====================...........=================
  TABL1... TABL1_2012_07_16... TABL1_IDX_2012_07_16... TBS_2012_07_16
  TABL1... TABL1_2012_07_15... TABL1_IDX_2012_07_15... TBS_2012_07_15
  
  
  But now, when the job is run, it creates the index in the tablespace TBS_DATA default.
  
  Table_name... Nom_partition... Index_Part_name... Tablespace_name
  ============...================.............====================...........=================
  TABL1... TABL1_2012_08_16... TABL1_IDX_2012_08_16... TBS_DATA
  TABL1... TABL1_2012_08_15... TABL1_IDX_2012_08_15... TBS_DATA
  
  
  I can issue alter index rebuild to move the index to its tablespace default, but how can I make sure that the index is created in the designated tablespace?
  
  NOTE: the partition/tablespace management work that I run only creates the partition of the table and not the index.
  
  
  The new env is a cluster of CARS of 2 nodes 11 GR 2 on Linux x86_64.
  
  
  Thanks in advance,
  aBBy.

  try something like this

  ALTER table tab_owner.tab_name add the partition v_new_part_nm
  values less (to_date('''|| v_new_part_dt_formatted ||'') ((', "DD-MON-YYYY)) tablespace ' | part_tbs

  Hi all

  So, I consider this task fact and ok.

  But I don't know which partition has been marked as boot; hidden or whatever. There are 3 partitions on the first HARD disk that are the SYSTEM; WINDOWS and RESTORE

• Restore the partition from the Satellite Pro A200 recovery

  Hello

  I accidentally deleted the 5 GB recovery partition on my Satellite Pro A200. I have since recovered (and the data inside) and tried to create my discs of recovery using the "Recovery Disc Creator', but it is to say that it cannot find the recovery partition :(

  I tried fishing by the ini files for recovery disc creator find where he seeks the score, but could not find anything...

  One thing I noticed is that now it is recovered, it appears as a NTFS fs (I think that before it was an unknown FS type?) and volume label "HDDRECOVERY".

  Any ideas on how I can either:

  (a) wrong recovery tool by using the recovery partition
  (b) to make the score look exactly as it did before I deleted it, so I can use the tool as it is.

  Would really appreciate any help - want to make these recovery disc for my vista ultimate before I go around whacking backtrack top :) and dicking

  Hello

  > accidentally deleted the recovery partition of 5 GB on my Satellite Pro A200. Since I got (and the data inside)
  I wonder how you restored the deleted partition. Perhaps the recovery settings partition are not the same that before and, therefore, the "Recovery Disc Creator' doesn t work properly.

  Unfortunately, I think you will not be able to fool the recovery tool, if the recovery partition cannot be found.
  You can rename only the partition NTFS FS. This can be done in the disk management console.
  But I don t think this will solve this problem.

  It seems that you have to reinstall the whole OS using the CD of restoration of Toshiba or the original CD of Microsoft Vista

• How do I restore the partition hidden bootcamp

  Hello

  I had the partition, bootcamp for windows 7 and I had restored the bootcamp. Bootcamp deleted the partition, but it could not restore the main HD storage size. How to restore the free space.

  

  Hello there, elixir_125.

  Looks like you're wanting to reformat the hard drive on your MacBook to delete the Bootcamp partition. The following Knowledge Base article offers up how to do this:

  How to reinstall OS X on your Mac

  Wipe your drive and install OS X

  Generally, you don't need to erase your startup disk to reinstall OS X. The OS X Installer is designed to allow you to perform an installation in place during the same version or earlier versions of Mac OS X. If you transfer your Mac to a new owner, you can clear your integrated boot disk before you reinstall OS X.

  Important: Before you remove and reinstall, back up your important files. If you are using a MacBook, MacBook Air or MacBook Pro, make sure that the power adapter is connected and plugged all by performing the following steps.

  You can use these measures to erase files on your startup drive and install a fresh copy of OS X:

  1. Before you begin, make sure that your Mac is connected to the Internet.
  2. Restart your Mac. Immediately hold down the command (⌘) keys and R after having heard the startup sound to boot into OS X Recovery.
  3. When the recovery window, select disk utility, then click on continue.
  4. Select the volume name back from your startup disk in the left side of the disk utility window, then click Delete.
  5. If you want to erase the disc safely, click Security Options. Select an erasing method, and then click OK.
  6. On the Format menu, choose Mac OS extended (journaled). Type a name for your drive, and then click clear.
  7. After that the drive is deleted, close the disk utility window.
  8. If you are not connected to the Internet, select a network in the Wi-Fi menu.
  9. Select the option to reinstall OS X.
  10. Click on continue and follow the instructions on the screen to reinstall OS X.

  Additional options

  If you want to reinstall the version of Mac OS X included with your Mac, or if you have to reformat your entire startup disk, press Command + Option + R to start instead. This starts your Mac recovery of the Internet.

  If you have more than one partition (like Boot Camp) and you want to delete the complete startup disk, you can use disk utility to remove the partitions or re-partition your hard drive. Start up your Mac in recovering from Internet, then use utility to repartition your boot disk drive until delete you it. Make sure that you back up important data from all partitions before repartitioning of a disc.

  Thank you for being a part of the communities of Apple Support.

  See you soon.

• HP ProBook 650 G1 L4A21UT #ABA: windows 10 update and restore the partition

  I have recently updated from Win 7 to 10 to win. I'm assuming that the Win 7 recovery partition was intact. Is this a problem?

  Also, when I restarted after the upgrade, accelerometerST.exe "not found."

  I googled for it and found the link to 10 to win, but I was unable to download.

  Should I just ignore the missing .exe?

  Kind regards

  Joe (aka Malcolm)

  @K8MP

  Creating recovery media is something done before the partition is non-functional.

  The 'Upgrade' comes with the ability to 'come back' to your operating system already installed.  There is a time limit: If you want to "go back", you must do so within the 30 (or 31) days from the date / time of the migration to Windows 10.

  The 'go back' is a provided Windows mechanism - it seems that the method works (to restore the previous operating system / full environment) most of the time.  The 'go back' method does not work, you prefer should be prepared to install the operating system.

  Now that you have your digital license of Windows 10 (also known as the 'right'), you can "go back" or reinstall Windows 10 at a later date.  Your license for Windows 10 "sticks", in other words, Microsoft a record or your license so you can return to / install Windows 10 on this same machine.

  Update Windows 10 and HP System Recovery

  Your Systemis Windows 10 drivers - it is a good indicator that the computer runs Windows 10 with less problems if the system was not supported for the new OS.

  If you decide to stay on Windows 10, consider using the image / ghosting software to create a "recovery disc" disc.

• How to remove the partition of data (D) on the Toshiba Satellite

  Hi, I have a Toshiba C660, which is part of the series of satellites. I got my laptop yesterday and while I was looking at the capacity of the hard drive that I have seen that there are 2 partitions. A partition is my C drive and the other is my D drive, drive D is called 'data' and I double click on the folder, there is a folder named "HDD Recovery." Is it not possible to delete this partition, because I don't think that this partition is necessary and I'd like to expand my C drive using the D drive space.

  Thank you

  Partition D, your description, would appear to be a recovery partition. If so, it is provided so that the computer can be recovered/restored to the State it's in when the computer was delivered to you.

  If you have other means in place to make this (backups of the entire system to storsge external, for example), the partition could be deleted and the space used for other purposes. If you do not have such a plan for backup in place, you can delete it anyway - it's your computer. However, it would be unwise, in my opinion - but it's not my computer.

  Happy computing and good luck.
