Windows 10: Lost partitions after Diskpart clean with no OS support

I created a second partition in my HD for installing Windows 10 in the first I have Window 7 in dual boot but installation asks me a GPT disk so I execute these commands in this order:- diskpart- list disk- select disk- clean- convert gpt- exitAfter this I found that I have lost all partitions in my drive and I have no OS support.Can I undo these operations and restore my partitions with my data?Thanks in advance

Use DiskPart to Create the OS Partition on Clean Install.

I have a Laptop HDD [ my preferred option as opposed to an SSD on this Laptop ] arriving on Friday and I want to use DiskPart to Setup the size of the OS Partition. The main reason I want to do it this way is because DiskPart can create an exact 30 GB Partition [ my OCD ] for example. Here are the steps that I tried the other day which did NOT work . . .

• Boot from the install USB.
• On the Windows Installation Screen press Shift + F10.
• diskpart
• list disk
• select disk 0
• clean
• create partition primary size=30000
• exit
• exit

I intend to leave assign AND format fs=ntfs for Windows to perform as normal during the installation.

Thanks.

 

Lost recovery partition

Hello, I see that you are having issues with recovery partition. I would suggest you using the diskpart command in the command prompt. First, open up the comand prompt as an administrator, then type in diskpart. Now, type in list disk, and look for the
recovery partition drive. Follow the steps in the link below:

Hope this helps, and let me know if you have further questions!

 

Use DiskPart to Create the OS Partition on Clean Install.

Those were the steps I did.

Because I figured that Microsoft, in their infinite wisdom, would have required Windows setup to create a separate system and/or recovery partition.
