uhm... did you format your hard disk?
i guess you tried to format your hard disk and lost your backup recovery.

you should have went to the recovery instead and restored factory settings.

i think you lost your recovery. did you try to install a new OS and reformatted it thru the installation? if so, im afraid you really lost your backup.

The factory backup was lost. Starting an installation of Windows 2000, that is the harddrive format part, allowed the Acer recovery disks to work.
Thanks so much,

I experienced the same problem on my Acer Aspire 4720Z. As usual, the Acer support folks were not much help. They just send you the instructions to recover your system. They don't tell you how to get past the type mismatch error. I think this error message has something to do with the OS partition (partition 2) being corrupted. The way I got past the type mismatch error was to boot up using a WinPE CD then format partition 2 using diskpart. Here is a link from MS on how to create a WinPE CD.
Here are the steps to use diskpart. Insert the WinPE CD in your CD drive. Change your BIOS setting to use CD/DVD as the first boot option. Save your changes and boot up. Once your machine boots up with WinPE, at the prompt, type diskpart then hit enter. Enter the following commands and hit enter after each command is typed: select disk 0, select partition 2, format fs=ntfs quick. When all done, type exit then hit enter. Insert your Acer disk formatter then reboot the machine. Follow the instructions to format partition 2. When done, insert your Acer System Disc then reboot. Follow the prompts to recover your system. You will need the Acer Recovery discs. Follow the prompts. You will see a progress screen. Hope this helps!
