Windows 10: Can diskpart delete C: while running the OS?

I want to know that: Can diskpart can delete C: drive?

:)

 

diskpart doesn't show disk

Hey,

I am trying to install Win10 on a mac book air.

However the diskpart does not list the disk even after reformatting the partition as NTFS per suggestion.

read through this solution but cannot move to step 1 listed in the solution by Ivan as that disk doesn't see that partition it was just able to reformat.

Regards

 

Windows.old automatically deleted the day after installing Windows 10

A simple websearch would have given you info quicker than complaining about someone suggesting to upgrade to Windows 10 and something causing the Windows.old to be deleted, which I doubt was caused by Microsoft.
Rebuild System Partition

The second way here we can put forward is to rebuild the system partition. If you don't want to pay a penny to do the lost partition recovery, try this method. Note that this requires you have the Windows installation disk. Now follow the instructions to begin.
Preparatory work:
Boot the computer using the Windows installation media for your running OS. Then on the first installation screen, press SHIFT+F10 to bring up the command prompt.
Now run the following commands at the command prompt.
Step 1:
bootrec /fixmbr
Step 2:
diskpart
select disk 0
list partition
select partition n (n is the Windows OS partition)
active
exit (exit diskpart)
Step 3:
bootrec /fixboot
Step 4:
bootrec /rebuildbcd

 

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.
