Will this create a new start up disk?

How, exactly, did you delete your startup volume?

Do you have a recovery flash drive installer? You cannot buy one. You have to make one using an installer from Apple. You can only use the retail Snow Leopard DVD if your computer does not require a later version of OS X than 10.6.3. In order for you to make a flash drive installer you need to way to download the actual Apple installer from the App Store. To do that you must be using a Mac with 10.6.8 or later installed.

You can purchase Snow Leopard through the Apple Store:Mac OS X 10.6 Snow Leopard - Apple Store (U.S.). The price is $19.99 plus tax. You will be sent physical media by mail after placing your order.

After you install Snow Leopard you will have to download and install the Mac OS X 10.6.8 Update Combo v1.1 to update Snow Leopard to 10.6.8 and give you access to the App Store.

At one time Apple sold a Lion 10.7 installer on a flash drive. They no longer do so, but you can search for ones on Google, Amazon, and eBay.

Which computer model do you have? A Lion installer will create a new startup volume. That's what an OS X installer does. Do you have a functioning Recovery HD on your computer as of now? What version of OS X was your computer running?

Then you don't need a flash drive to reinstall from scratch. You use Internet Recovery:

Install OS X Using Internet Recovery

Be sure you backup your files to an external drive or second internal drive because the following procedure will remove everything from the hard drive.

Boot to the Internet Recovery HD:

Restart the computer and after the chime press and hold down the COMMAND-OPTION- R keys until a globe appears on the screen. Wait patiently - 15-20 minutes - until the Recovery main menu appears.

Partition and Format the hard drive:

1. Select Disk Utility from the main menu and click on the Continue button.
2. After DU loads select your newly installed hard drive (this is the entry with the mfgr.'s ID and size) from the left side list. Click on the Partition tab in the DU main window.
3. Under the Volume Scheme heading set the number of partitions from the drop down menu to one. Click on the Options button, set the partition scheme to GUID then click on the OK button. Set the format type to Mac OS Extended (Journaled.) Click on the Partition button and wait until the process has completed. Quit DU and return to the main menu.

Reinstall OS X: Select Reinstall OS X and click on the Install button. Be sure to select the correct drive to use if you have more than one.

Note: You will need an active Internet connection. I suggest using Ethernet if possible because it is three times faster than wireless.

This should restore the version of OS X originally pre-installed on the computer.

Did you repartition the drive as shown in my procedure? If you did and the installation still failed then there are three things to consider:

1. Use Ethernet rather than Wi-Fi. Be sure to turn off Wi-Fi before proceeding, if possible.
2. The hard drive has failed and will have to be replaced.
3. There is a defective memory module.

What won't let you partition the drive? You need to explain these answers in detail, otherwise I don't know what has happened.
