Hey 

 

I have a Dell Latitude E6230 Running Win8 Pro 64Bit

 

When I boot up I get Invalid partition table and it freezes

The first time I could not do anything. Ran it up with installation usb auto repair did not work. Managed to go to restore point.

The first restore point did not work it was made when installed windows update.

This time I was able to go into F12-> UEFI BOOT -> Windows boot manager 

The second restore point (older one) did work and was told successful. 

When I booted got the same message about the table. Went into the boot sequence ->  Windows boot manager the windows boots all the way up and can log in.

When I shut down or restart I get the same message again.

 

After searching I understand that I should try and fix the MBR

Went into recovery on windows boot usb -> command prompt  enters the following

bootrec /FixMbr
bootrec /FixBoot
bootrec /ScanOs

 

  -> after theese I get success
bootrec /RebuildBcd

after this I get

The required system device cannot be found

Picture mbr.jpg

 

 

Doe's anyone have another idea ?

 

Thanks

There was file system corruption which was repaired don't worry about the error at the end of the Chkdsk command output.

Can you tell me which command has failed and giving you that error message.

I'm sorry my mistake, you need to first enter C: and press Enter key. Execute bcdedit /export C:\BCD_Backup  and other commands.

We need to mark System Reserve partition active to do that i need you to execute below commands and please post picture of the commands.

Diskpart

List Disk

Select disk X

List volume

List partition

Replace the X with disk number assign to Windows installed disk the "List Disk" command will list all attached disks and disk number assign for the disks.

Hi Vally,

Diskpart

Select Disk X

List partition 

Select partition 1

If the commands executed without error then you can test and see if Windows boots after executing above commands.
