Windows is not shown as installed

[theusername]

I am trying to dual boot but when I press Install on Linux Mint it says "No other operating systems can be found"
I have Windows 8 installed currently.

Is there any other info i have to provide too?

From the live cd/dvd choose gparted.
once running you will see (prob) 4 partitions already on the machine - you cannot have more than 4 primary partitions - mint will try to install a new primary partition...

One of your partitions will be a windows recovery partition.

One of your partitions will be the main windows partition.

Main Windows Partition
If you are happy with the windows setup use a backup program, if not use the recovery program to reinstall a fresh windows setup NB this will be destructive, once complete and setup; use - http://www.macrium.com/reflectfree.aspx

Recovery Partition
Use a backup program - http://www.macrium.com/reflectfree.aspx
Delete the Recovery Partition and shrink the others, using gparted or ubiqity.

Delete the Recovery Partition and shrink the others- if you dont want to use windows delete this partition as well.

Use Gparted to make an extended partition in the free space them inside that make a root (/) partition, /home and lastly a swap partition of about 2Gb
My sig has video tutorials for the install, also look at viewtopic.php?f=42&t=121912

Ok the partitions on my hardrive right now are:
Recovery
ESP
Blank (doesnt have a name, but has 128MB capacity)
C: Acer
Push Button Reset

So I backup Recovery and then wipe it, what about Push Button Reset?
Would this just be easier if I wiped my harddrive and installed Windows 7? Windows 8 is the reason why theres so many partitions...
