Error in booting Windows after Ubuntu installation failure

[gkumar]

Hi everyone,

I am using Windows 7. I tried installing ubuntu with the option " Include Ubuntu along with window partition".

While installing ubuntu, error occurred. Now unable to boot Windows also. It prompts for recovery cd.

I am not having recovery disk.

Tried using other machine's recovery cd - Diskpart. But got the following error while selecting a partition.

virtual disk service error:
this operation is not allowed on an invalid disk. The disk may be invalid beacuse it is corrupted or failing, or it may be invalid because it is offline.

Required your help to recover windows without affecting the existing data.

Thanks.
