I cannot get the acer erecovery management page to give me the option of making a DVD recovery disk

Two seperate issues. You can order new disks on ebay for example but if your product key is unreadable you need to purchase a new key.
See this link to buy - http://www.amazon.co.uk/Microsoft-Windows-Home-Premium-inkl/dp/B008OT79T4/ref=sr_1_2?ie=UTF8&qid=1426423337&sr=8-2&keywords=windows+7+coa

When you need to recover part or all of the files on your Acer Veriton M460 desktop computer, Acer makes it easy to do by offering a built-in recovery program called eRecovery Management.
This option uses clean operating system files, usually stored on a separate partition of your hard drive, to correct errors or return the system to its original factory settings.
You can also use this program to write separate hard copies of the eRecovery program onto CDs or DVDs in case of hard drive failure.
Create Backup Disks
If your M460 did not come with separate recovery disks, and many machines don't in recent years, you can create your own through "Acer's eRecovery Management" program located under the "Start" menu.
Click on "Backup," select "Create Factory Default Disk" and follow the on-screen directions.
The program will inform you of the number of CDs or DVDs you need and help you through their creation.
Recovery with Disks
To use your created disks for recovery, place the first disk in the optical drive and reboot the system. As it boots, hold the "ALT" key and tap "F10" repeatedly until the computer boots and you see a screen titled "Starting Acer eRecovery."
You will see three options for recovery: to factory default, from user backup or from CD/DVD. Choose the option you desire and follow the on-screen directions to initiate the recovery sequence.
Recovery from the Hard Drive

Since Acer places the eRecovery Management program directly onto the computer, you can run the recovery option while in your desktop.
Open the "Acer eRecovery Management" program under the "Start" menu and click "Restore." You can choose to restore the computer to factory defaults and lose all the personal data stored on the hard drive or only restore the operating system and leave your data intact.
Select "Yes" on the confirmation screen and then "OK" to start the program.
Recovery Vs. Restore
When performing computer problem solving, the term "recovery" is often used interchangeably with the word "restore."
In some cases, "recovery" can mean to simply correct problems, such as replacing corrupted operating system files with good ones.
The term can also refer to "recovering" the system to its fresh-from-the-factory state, which is what "restore" means as well.
Restore Drivers or Applications

Acer's eRecovery Management program also offers the option to reinstall drivers or applications, which could become corrupted or damaged over time.
This option allows you to replace the current drivers for your Windows operating system with the ones originally installed on your system.
Under the "Restore" tab of the "Acer eRecovery Management" program, click "Reinstall Drivers or Applications" to see the content list and select the files you'd like to recover.

Ask acer for this problem, when you buy a laptop you need to make recovery discs, you prolly did not do that. So now it asks for recovery files on the dvd disc.
If it has no dvd drive you should have made them on a usb drive.
If acer cant help you with that, reinstall windows thats the only option.
Partitions hidden can be removed but then there is no way to restore the pc to factorydefaults anymore.

When you decide to reinstall windows, you will see 3 partitions, remove them all, then make 1 partition click next and it will make a little partition for system files. the rest is used for windows, untill u partition the rest, like a d: e: drive.

Instead of going with a backup and recovery try the destructive recovery option which will wipe off the entire harddrive and take the system to day one settings.

Acer eRecovery Management
Acer eRecovery Management is a tool to quickly backup and restore the system.
You can create and save a backup of the current system configuration to hard
disk, CD or DVD. You can also backup/restore the factory default image, and
reinstall applications and drivers.

Acer eRecovery Management consists of the following functions:

1 Create backup
2 Burn backup disc
3 Restore and recovery

This chapter will guide you through each process.
Note: This feature is only available on certain models. For systems
that do not have a built-in optical disc burner, plug in an external
optical disc burner before entering Acer eRecovery Management
for optical disc-related tasks.

When using Acer eRecovery Management, you may be prompted to enter the
Empowering Technology password to proceed. The Empowering Technology
password is set using the Empowering Technology toolbar or when first running
Acer eLock Management or Acer eRecovery Management.

You can easily create full and fast (incremental) backup images of your system
configuration to hard disk from the main Acer eRecovery Management screen.

Note: Create a factory default image when you want to burn a
bootable disc that contains your computer's entire operating
system as it was delivered to you from the factory. If you wish to

selected drivers and applications, create an application backup
image instead — this disc will not be bootable.
