Then I checked
>list partition
No partitions are available

Please help me out.....

Do you have data you want to try to recover, or are you just wanting to install Windows 10 again? If you are just trying to install Windows 10 again, you do not need to recover any partitions. Just pick the unallocated space to install to.

If you are trying to recover data, then don't do anything more to write to the drive, or you will keep losing data the more you write to the drive. You will have to download a recovery program, make a bootable USB drive of it, boot the computer from it, and attempt to recover the old partitions.

MiniTool data recovery software – Power Data Recovery and Mac Data Recovery.

Hi NavyLCDR,

Thank you for answering.

I'm trying to recover other two partitions. I have Windows10 bootable USB, and downloaded above mentioned tool. How can I proceed after this. Could you please help me with the steps to get back old partitions?

Thanks in advance.

You are going to have to use another, operating computer, and download the software like I linked to. Make a bootable USB flash drive of it (I think the software itself should do that for you), then use that to recover the partitions on the computer with the drive that you wiped.
