Grazie di tutto,ho visto che forse un modo potrebbe esserci ma ora sto
usando win98,ho estratto il programma dskprobe.exe e quando lo apro un msg
mi dice che è un'applicazione nt e non è supportato dal 98.Tu sapresti
qualche sito dove c'è una guida xchè io non so proprio come si usi quel
programma!
Fammi sapere appena puoi
Ciao e grazie

 si usi quel programma!
Ciao, guarda se questo ti aiuta.
Comunque in effetti devi far partire l'utility da un windows 2000 e loggato
come administrator.
SUMMARY
=======
This step-by-step article describes how to use the DiskProbe Tool
(Dskprobe.exe)
to display, back up and restore the master boot record (MBR) of a Microsoft
Windows 2000-based computer.
Overview of DiskProbe
---------------------
DiskProbe is included with the Windows 2000 Support Tools which you can
install
from the Support\Tools folder of the Windows 2000 compact disc (CD). It is a
sector editor that you can use to directly modify data on the computer's
hard
disk. With DiskProbe, you can edit data structures such as the master boot
record, partition tables, and partition boot sectors. For example, you can
replace the MBR, repair damaged partition table information, repair or
replace
damaged boot sectors, or other file system data. You can also save MBRs and
boot
sectors as backup binary files in the event that the original sectors are
damaged. Because these structures are not considered a part of a file
system,
they are not accessible using the disk tools that are included with the
operating system.
DiskProbe does not support all of the disk-based features that are available
in
Windows 2000. Note the following limitations:
 - DiskProbe does not support FAT32 boot sectors.
   You can use DiskProbe to display, edit, and search for sectors on a FAT32
   volume, however you cannot view or edit the FAT32 boot sector using
different
   View modes. In order to edit the FAT32 boot sector, you must use the
default
   Bytes view.
 - DiskProbe does not support dynamic disks.
   DiskProbe fully supports basic disks. However, if you convert a basic
disk to
   a dynamic disk, you cannot use all of the functionality of DiskProbe on
the
   dynamic disk.
You must be logged on to the computer as Administrator or as a member of the
Administrators group in order to use DiskProbe.
WARNING: Before you use DiskProbe, make sure that you perform a complete
back up
of all data on the disk. Incorrect use of this tool can render all data on
the
drive or volume permanently inaccessible. DiskProbe functions at a level
below
the file system. It allows direct access to every byte on the physical disk
which makes it possible to damage or permanently overwrite critical data
structures.
How to Install DiskProbe
------------------------
DiskProbe is installed when you install the Windows 2000 Support Tools. To
install the Windows 2000 Support Tools (including DiskProbe), follow these
steps:
1. Insert the Windows 2000 CD into your CD-ROM or DVD-ROM drive.
2. Click Browse This CD, and then browse to the Support\Tools folder.
3. Double-click Setup.exe, and then follow the instructions that appear on
the
   pages of the Windows 2000 Support Tools Setup Wizard to install the
Windows
   2000 Support Tools.
4. Click Finish when setup is complete and then remove the Windows 2000 CD
from
   the computer's CD-ROM or DVD-ROM drive.
How to Display the Master Boot Record
-------------------------------------
To display the MBR, follow these steps:
1. Click Start, point to Programs, point to "Windows 2000 Support Tools",
point
   to Tools, and then click DiskProbe.
2. On the Drives menu, click Physical Drive.
3. In the Available Physical Drives box, double-click the disk that contains
the
   MBR that starts the computer (usually PhysicalDrive0).
   NOTE: The drives are listed as PhysicalDrive<n>, where <n>=0 for
   the first hard disk, <n>=1 for the second hard disk, and so on. The
   startup disk is typically PhysicalDrive0.
4. Click Set Active, and then click OK.
5. On the Sectors menu, click Read.
6. Type "0" (without the quotation marks) (zero) in the Starting Sector box
(if
   it is not already displayed).
7. Type "1" (without the quotation marks) in the Number of Sectors box (if
it is
   not already displayed).
8. Click Read.
   The sector information is displayed in the DiskProbe window.
How to Back Up the Master Boot Record
-------------------------------------
To back up the MBR, follow these steps:
1. Click Start, point to Programs, point to "Windows 2000 Support Tools",
point
   to Tools, and then click DiskProbe.
2. On the Drives menu, click Physical Drive.
3. In the Available Physical Drives box, double-click the disk that contains
the
   MBR that you want to back up (usually PhysicalDrive0).
   NOTE: The drives are listed as PhysicalDrive<n>, where <n>=0 for
   the first hard disk, <n>=1 for the second hard disk, and so on. The
   startup disk is typically PhysicalDrive0.
4. Click Set Active, and then click OK.
5. On the Sectors menu, click Read.
6. Type "0" (without the quotation marks) (zero) in the Starting Sector box
(if
   it is not already displayed).
7. Type "1" (without the quotation marks) in the Number of Sectors box (if
it is
   not already displayed).
8. Click Read.
9. On the View menu, click Partition table. Verify that DiskProbe correctly
   identifies the partition type and that Unknown Type is not displayed in
the
   System ID box.
10. On the File menu, click Save As. Specify a file name and location where
you
   want to back up the MBR (for example, the Emergency Repair Disk), and
then
   click Save.
   The MBR is backed up to the location that you specified.
NOTES:
 - You may want to back up the MBR to more than one floppy disk. Do not save
the
   backup copy of the MBR to the local hard disk because if the partition
table
   becomes corrupt, you may not be able to gain access to the volume that
   contains the backup copy of the MBR.
 - When you perform any disk operations that affect the MBR such as when you
   repartition disks, use a different file system, or convert a basic disk
to a
   dynamic disk, use DiskProbe to create updated backup copies of the MBR.
How to Restore the Master Boot Record
-------------------------------------
If the MBR of a non-startable disk is damaged, you can use this procedure to
restore the MBR. To do so, follow these steps:
1. Click Start, point to Programs, point to "Windows 2000 Support Tools",
point
   to Tools, and then click DiskProbe.
2. On the Drives menu, click Physical Drive.
3. In the "Available Physical Drives" box, double-click the disk that
contains
   the MBR that you want to restore.
   NOTE: The drives are listed as PhysicalDrive<n>, where <n>=0 for
   the first hard disk, <n>=1 for the second hard disk, and so on. The
   startup disk is usually PhysicalDrive0.
4. Click to clear the Read Only check box.
5. Click Set Active, and then click OK.
6. On the File menu, click Open File. Locate, and click the back up copy of
the
   MBR, and then click Open.
7. Click Write on the Sectors menu.
8. In the "Starting sector to write data" box, type "0" (without the
quotation
   marks) (zero), then click "Write it".
9. When you are prompted to confirm overwriting the existing data, click
Yes.
   The MBR is restored from backup.
NOTES:
 - Make sure that the MBR that you restore is from the same disk to which it
is
   applied. The back up copy of the MBR must exactly match the current disk
   configuration of the computer. If it does not, partitions and the data
they
   contain may be permanently lost.
 - If the MBR of the startup disk is damaged, you may be unable to gain
access
   to the partition in order to start Windows and run DiskProbe to restore
the
   MBR.
Troubleshooting
---------------
When you run Dskprobe.exe, no drives are displayed in the Available Physical
Drive list of the Open Physical Drive dialog box.
This behavior can occur if you are not logged on to the computer with
administrator privileges. In order to use DiskProbe, you must be logged on
as
Administrator or as a member of the Administrators group.
To resolve this behavior, log on to the computer as Administrator or as a
member
of the Administrators group.
Ciao

Ho installato win2000 su un altro hd,
più ho meno ho capito come usare il programma solo che ho dei dubbi su
questa cosa:
__________________________________________________________
 - Make sure that the MBR that you restore is from the same disk to which it
is
   applied. The back up copy of the MBR must exactly match the current disk
   configuration of the computer. If it does not, partitions and the data
they
   contain may be permanently lost.
 - If the MBR of the startup disk is damaged, you may be unable to gain
access
   to the partition in order to start Windows and run DiskProbe to restore
the
   MBR
____________________________________________________________
L' MBR lo devo leggere dal 2° hd funzionante(su cui sto usando il
programma)oppure devo leggere qualcosa dall'hd dal quale ho cancellato la
partizione primaria?
Grazie di tutto

 Grazie di tutto
L'MBR devi leggerlo dal disco che hai cancellato, dopo averlo recuperato
seguendo le istruzioni dell'articolo Q245725 che avevo segnalato
precedentemente.
Fammi sapere



Allora ho seguito le istruzioni del sito,con fdisk ho ricreato la partizione
nell hd e ho copiato l'MBR nel settore 0 ma quando avvio ckhdsk dice che il
file system è di tipo RAW e non supporta chkdisk.(e provando ad avviare l'hd
dice sempre SO mancante)Se sai qualcosa a riguardo fammelo sapere!
Grazie

 qualcosa a riguardo fammelo sapere! Grazie
Ciao, fai riferimento a questo articolo. (si riferisce più che altro a
FAT32)
http://support.microsoft.com/default.aspx?scid=KB;EN-US;Q247575
La partizione che hai accidentalmente cancellato era FAT32 o NTFS?



Ah mi ero scordato di scriverlo,č FAT32

 Ah mi ero scordato di scriverlo,è FAT32
Ok, allora guarda l'ultimo articolo che ti ho mandato. Si riferisce proprio
all'errore sul Raw che stai avendo tu.


 Ciao
Sono ancora qua,(lo so che sono stressante) il problema è che chkdsk non mi
parte neanche dopo la sosituzione del settore  mentre da quanto ho capito
nel sito dice che il problema viene prima.
