Last part for GPT !


DISKPART> help attributes volume

Displays, sets, or clears volume attributes for the selected volume.
Syntax: ATTRIBUTES VOLUME [SET | CLEAR]
[HIDDEN | READONLY | NODEFAULTDRIVELETTER | SHADOWCOPY] [NOERR]
SET Sets the specified attribute (HIDDEN, READONLY, and
NODEFAULTDRIVELETTER or SHADOWCOPY) for the selected volume.
CLEAR Clears the specified attribute (HIDDEN, READONLY,
NODEFAULTDRIVELETTER or SHADOWCOPY) from the selected volume.
HIDDEN Specifies that the volume is hidden.
READONLY Specifies that the volume is read-only.
NODEFAULTDRIVELETTER
Specifies that the volume does not receive a drive letter by
default.
SHADOWCOPY Specifies that the volume is a shadow copy volume.
NOERR For scripting only. When an error is encountered, DiskPart
continues to process commands as if the error did not occur.
Without the NOERR parameter, an error causes DiskPart to exit
with an error code.
On basic master boot record (MBR) disks, the HIDDEN, READONLY, and
NODEFAULTDRIVELETTER attributes apply to all volumes on the disk.

On basic GUID partition table (GPT) disks, and on dynamic MBR and GPT
disks, the HIDDEN, READONLY, and NODEFAULTDRIVELETTER attributes apply
only to the selected volume.

Using attributes volume causes an error: Virtual Disk Service error: The object is not found.

I think my last resort for this problem is setID http://technet.microsoft.com/en-us/l...753840(v=ws.10) of the Windows partition from EFI system partition to Basic data partition. As mentioned in CREATE_PARTITION_PARAMETERS structure (Windows), only basic data partition can be recognized by Windows.

Moreover, Saltgrass, could you confirm that the Windows partition in your PC is not a EFI System partition ?
Any comment before I doing this ?

EFI with GPT disks are going to create much headache, I think, until we get enough knowledge.

attr vol is only a shortcut for attributes volume. Therefore, the same error

View if running:
Task Manager (all processes) shows vds.exe

See properties of service:
Using Control Panel -> Administrative Tools -> Services

Virtual Disk (my is set to manual by default)
Service is started when needed by the system I think.

Ok. I was able to fix this problem by set id=ebd0a0a2-b9e5-4433-87c0-68b6b72699c7 which is for a basic data partition.
Thank you SaltGrass and boyans for your help. I really appreciate your support. Without both of you, I wouldn't be able to fix this problem. Thank you very much.

Not really sure the current situation would suggest this. But I do wish manufacturers would make an effort to inform their customers when a UEFI system is being used, and perhaps some direction about certain procedures, such as how to boot to a UEFI DVD...

I have a question:

If this disk was installed using EFI then how was there a Logical partition, since my understanding is that EFI can only be installed to a GPT disk which allows no Primary or Logical partitions?
