unable to delete partitions for clean install windows 7

Trying to do a clean install Windows 7, have enough space, Dell Studio 1555 laptop. When I get to the screen "Where do you want to install Windows?" I have:

Disk 0 Unallocated Space 298.1GB

At the bottom of the screen:

Refresh
Load Driver
Delete (grayed out)
Extend (grayed out)
Format (grayed out)
New

When I tried to delete Disk 0, not able to.

Been searching on the net for a solution, none found. I am unable upon boot to a command prompt in order to run diskpart. Lost.

Try using the boot disk from MiniTool;

All greyed out because only partitions can be deleted, extended or formatted.
DISK 0 has no partitions yet! It's totally empty. That's why it says "unallocated space"

Hello western hognose, and welcome to Seven Forums.

It sounds like you are good to go actually. You should be able to select the Disk 0 Unallocated Space to install Windows on like in step 7 of the tutorial below.

Brink, tried step 7 on the tutorial, some reason it didn't work. When I clicked on "New" and entered another value for a partition, the error message says "Failed to create a new partition on the selected unused space" Error: 0x8007045d

Problems installing Windows 7 on a blank hard disk

I really hope someone can help me with this. I have tried everything to no avail. Dell Studio 1555 laptop is the culprit. I am unable to delete a partition, also unable to create new partitions. I have struggled with this for a week now, and I do appreciate all the fine people that have tried to help me. I have set the SATA controller to AHCI, Hard drive first to boot, Save changes and exit. Here is where it gets tricky:

I am unable to access System Recovery Options (there is none on the advanced boot menu), Shift + F10 does not open a command box, so I am left with no other options.

This is very strange, I have never had any issues with installing any Linux or Windows O/S's in the past. This one really has me baffled.

Disk 0 Unallocated space 298.1 GB
"Setup was unable to create a new system partition or locate an existing system partition. See the setup log files for more information"
This is what I am seeing.

On the Windows 7 screen, the only thing that is highlighted is "New"....everything else is grayed out.

I kindly appreciate any help on this matter.
