Good morning everyone !

I am new to the forum. I have read some postings here but did not find something that could help me. After unexpectedly shutting down ( on low battery) my Dell Latitude 610 with Windows 7 Ultimate 32-bit do not boot anymore and I am receiving the error message “Invalid partition Table”. Unfortunately, I did not save my Documents and don’t have “System Image” to restore the system.

I would appreciate any help.

 

Thank you !

Greetings,

 

Sorry to hear about your problem maybe I can be of assistance. I would recommend the following steps to see if you can fix your invalid partition table.

 

  • Disconnect or remove all removable or external drives.
  • Restart the computer.
  • Wait for the BIOS status screen to appear. The screen will either have the logo of the computer manufacturer (such as Dell) or be black with white letters and many technical details.
  • Press and hold the "F8" key as soon as the BIOS screen disappears. The Windows "Advanced Boot Options" menu appears on the screen.
  • Select “Repair Your Computer,” and then wait for the Windows 7 Recovery Environment to load.
  • Select your keyboard layout from the drop-down box.
  • Log in using an administrator account, if necessary. The “System Recovery Options” window appears.
  • Click “Command Prompt.”
  • Type “bootrec /fixmbr” without quotation marks.
  • Wait for the process to finish and restart the computer to see if it worked. If it did not work, repeat steps 2 through 8, then continue to the next step.
  • Type “bootrec /fixboot” without quotation marks at the command prompt.
  • Wait for the process to finish and restart the computer to see if it worked. If it did not work, repeat steps 2 through 8, then continue to the next step.
  • Type “bootrec / RebuildBcd” without quotation marks at the command prompt. If the command is not successful, it’s likely that the disk is not recoverable and you will have to format the disk and re-install the operating system.

You shouldn't lose any saved or unsaved data files. You might consider getting and using Macrium backup/restore program.  It's free.  I use Acronis True Image [not free].  There are other programs as well, both free and fee.

RolandJS, could you give me step by step instructions, as I only get  a window "Invalid partition table" and I can't move from it...

 

Thanks.

I meant:  following the two previous posters' advice will not cause you to lose any data.

And, after you follow their advice, after they get you going -- then, you can download, install and use Macrium.

Sorry I did not post the above along with my earlier post.

Good day, everyone and thank you for your help.

 

I've done step by step instructions but stuck at the bootrec /fixboot. The error "no ellement found".

 

So I went to diskpart to lst disk to list partition. Under list partition I have : * partition 1 Primary, Size 74 GB, Offset 0 B (!!!)

When I tipe select partition 1,   I got " there is no partition selected". But under Volume I have Volume 0 that is DVD-ROM , healhy and Volume 1, Partition 74 GB, healthy. When I type select volume 1,  I got no partition selected....

 

So, my unerstading that something wrong with partition. Iit is not listed with MB or Kb or.....

 

How can I fix it ?

 

I would appreciate any advise,

 

Thank you all !

To all:

 

One more thing- Under System Recovery Options ( booted from CD) i do not have Operation System listed. My only option is to load drivers ? In that case I will lose all my documets... Is that correct ?

 

Thanks.

Maybe you used a wrong syntax

 

Diskpart>list volume

                     select volume X

                 assign letter=Y

 

Also, to check for volumes you can go to the Computer Management (right-click Computer and then choose Manage)

Under Storage double-click Disk Management. This should display your partitions. Right-click on anyone and it should give you some options. One is to assign a drive letter.

 

A third option is to download the free Aomei Partition Assistant. It will show your partitions and give you some options to play around with them.

Passacaglia : I am working at the moment on my second Dell Latitude 610 with XP.

 

I could download free AOMEI  on it but how can I  do something with my first  and corrupted Dell with Invalid Partition Table. I only can boot it from Windows 7 CD,  and do something with command prompt,   that's it......

I guess you could type "diskpart" in the cmd prompt
