Welcome to the forum.
Now I'm going to make a wild guess based upon pure intuition.
Here's what I 'll show you how to do:
To 100% write zeroes to your hard disk before the real install kicks in gear.
This will take a little while, influenced by the size of your hard disk.
- Turn on your computer. The purpose of this is so that the DVD door can be opened.
- Open the DVD door.
- Turn off the computer with the DVD door open.
- Insert the Windows 7 DVD and close the DVD door.
- Power on your computer.
- When that very first dialog appears where you would normally push the NEXT button, then use the SHIFT + F10 key combo to get to a command prompt.
- The command prompt will be X:>
Now you are going to run the DISKPART
program so that you can "clean" the hard disk.
In the following, type the command shown and then hit the Enter key.
Do not proceed to the next command until the current command is finished.
- DISKPART (the command prompt will change to DISKPART>)
- LIST DISK (this will list the disks present)
- SELECT DISK 0 (assuming disk zero is the desired hard disk)
- DETAIL DISK (this will show you info regarding the disk you selected)
- CLEAN ALL (this is the command to write zeros to entire disk)
- EXIT (this will exit you from the DiskPart program)
- EXIT (this will exit you back to the Windows 7 install program)
Let us know if all installs correctly now.
Now will someone tell me how do I post a reply which doesn't delete the extra spacing I throw in for readability. This is getting aggravating.
