How to Delete all Partitions during Win7 Installation?

How to delete all HDD Partitions during the installation of Win7? I want to wipe out all of the existing partitions and make it 0 and then create new volumes with different sizes. I cant delete primary partition during installation. Or is there any other software i can use to delete all partitions of HDD and then start over again freshly?

Hello boogieboy.



I would suggest, after you have copied out or made back-ups of the data you need to save to external media, use Step One of this tutorial at the link below to do a wipe (secure erase) to the entire Hard Disk Drive, running this then using the outline in Step Two #2 to create and format a single 100GB partition using diskpart will get you the best possible space to clean install Windows 7 to.

DISKPART : At PC Startup



Be sure to post back with any further questions you may have and to keep us informed.

If you delete all partitions:

All data will be lost.

The system will not boot.

Your files will not be moved anywhere. They will be deleted and gone.

If you delete all partitions, you can reinstall with your Windows disk and create one or more partitions---you are right.

But you don't need to use EaseUS Partition Master to delete partitions. You can delete partitions during the Windows installation using the Windows disk.

You need to back up your data.

You can create additional partitions during the installation or after the installation is complete using Windows Disk Management.

That's about right. During the installation, you will come to a screen that asks about partitions and where you want to install Windows. You can delete partitions at that point. Look for "advanced drive options" or something like that.

If you delete all partitions, your entire drive will be "unallocated space" and Windows will then make a partition of that unallocated space, format it, and install Windows.
