Deploy dual boot image W7/Ubuntu

[Almeida]

Hello,

I have an error message when i deploy an image include W7/Ubuntu on a pc.

Erasing current MBR/GPT Tables … EBR signature for logical partition invalid; read 0x0000, but should be 0xAA55
Error reading logical partitions! List may be truncated!
Done

Have you an idea?

Tanks.

Are you able to re-upload the image?

It sounds like the GPT structures that you do not intend to be there have not been properly wiped.

Can you take the system you uploaded the image from and boot it into an Upload - Debug mode?

[Almeida]

Upload - Debug mode? What is it?

[Almeida]

no problem appears with Debug mode

[Tom Elliott]

Are you in debug mode now? It’s not going to show problems.

What I need you to do is find out if your disk still has GPT structures on it.

You can do this by running the command:

[code]gdisk -l /dev/sda[/code]

Report the output of that command here if possible.

Thank you,

[Almeida]

ok, this is the output

Thanks.

[Junkhacker]

that’s a download, not an upload

[Almeida]

No problem with upload.

[Junkhacker]

yes, but did you try uploading again after running [FONT=Consolas]gdisk -l /dev/sda [/FONT]?

[Almeida]

Ok I try upload

[Almeida]

Hello,

This is output of [FONT=Consolas][I]gdisk -l /dev/sda[/I] before uploading.[/FONT]

[FONT=Consolas]Thanks.[/FONT]

Hello,

The problem was the extended partition if you have a dual boot.
