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

 

Help, I deleted a partition, and can't seem to "extend" the other partition

Ok, here's how it happened.

I had 2 partition. XP and Win7 x86.

I shrank the Win7 x86 partition and created a new partition (Win7 X64)

I then deleted Win7 x86 partition.

edit: what warup suggested did the trick. It took 20+ minutes for that software to do it, but hey it worked.. Thanks

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.
