Windows 10: clean install after deleting partitions

I have deleted the partitions, and have the unallocated space partition, clicked on next, but it won't progress. There's an hourglass that just sits there. Nothing happening.

Clean Install Windows 10 partition issue

Hello,

Thank you for writing to Microsoft Community Forums.

I appreciate the troubleshooting steps performed to resolve the issue. However, let’s try with the further troubleshooting steps and see if it works. Initially, I would suggest you to create a bootable media with a USB/Flash drive of capacity 8GB.
For better understanding, you may watch the video with the procedure from the article on
How to Clean Install Windows 10 on a PC Step-by-Step
Guide.

Set the boot priority to USB once after creating a bootable media using a USB and proceed with the Windows Installation. On the drive selection window, press Shift + F10 keys to open the Command Prompt. Then follow the steps listed
below:

• Type the following command in the Command Prompt window and press Enter:
  diskpart
  
• Once after executing the above command, type the following command to list the current drives and press Enter:
  list disk
  
• List disk will give you the list of drives, use the following command to select the drive and press Enter: select disk 0
  
• Type the following command to check if the disk is online: online disk
  (if the disk is not online)
  
• Type the following command to clean the drive and press Enter:
  clean
  
• To create a partition, type the following command and press Enter:
  create partition primary
  
• To select the partition that you created, type the following command and press Enter:
  select partition 1
  
• To set the partition active, type the following command and press Enter:
  active (if this is the boot partition)
  
• Type the following command to assign a drive letter and press Enter:
  assign letter(letter)
  

• After completing all this, close the command prompt screen and click on
  refresh button.
  
• Then you will only have one drive with “unallocated space”, just select the partition to start the installation.
  

Let us know how it goes and I look forward to hearing from you soon.

W7 Hard drive partition issue

to get rid of that 100 meg windows partition that setup creates for you on a new install on a blank hdd:

- press shift+f10 when on the partition management screen in setup <-- this opens a command prompt
- diskpart <-- start the windows command line partition management tool
- list disk <--- list the installed hdds in this computer for the next step
- select disk 0 <- might have to replace 0 with the number of the correct disk
- clean <-- this will erase all data on the disk you selected one step up- dont use the wrong disk!
- create partition primary <- creates a primary partition taking up all space on the drive, adjust the command if necessary
- exit, exit to exit diskpart and the command prompt
- click refresh in partition manager and select your newly created partition and install to that

 

Error: We couldn't delete the selected partition. [Error: 0x800701b1] when trying to delete partition during Windows 10 installation

Hi,



Thank you for writing to Microsoft Community Forums.



We will need the following information from you to help you further:

• How are you trying to install Windows?
  
• Which partition are you trying to delete?
  

In the meantime, you can refer the steps mentioned below and see if that helps:



Method 1: Formatting the partition



If you are trying to delete one particular partition, you can format the partition and see if that helps. To format the partition, on the installation screen select the partition that you want to format and click on
Format.



Method 2: Using Diskpart command



If you are performing a clean installation on the computer and want to delete all the partitions from the computer, you may try using the Diskpart commands. Follow the steps mentioned below:

1. On the installation screen press Shift key + F10 to open Command Prompt.
   
2. Type Diskpart and hit Enter.
   
3. Type list disk.
   
4. Type select disk 0.
   
5. Type clean.
   
6. Now, close command prompt window and continue installation.
   

Note: Running clean command will erase all the information from the hard drive.
