You would boot from the "Windows Installation Media"
Then when asked where to install (HDD Partition Screen)
Delete EVERY partition
and point to the unallocated disk space
Windows will create it's own partitions....
use diskpart to assign the drive letter R
open file explorer and post a screen shot of the files and folders on R
You can now browse thru R and find Install.wim or Install.swm(s) - those are your Factory recovery Images..
there are two different settings..
One is for Recovery Tools (WinRE.wim)
One for the Factory Image
You would boot into WinRE to Restore the Factory Image...
Not sure what you mean "it just boots into ISO recovery"
we need to find the image and partition - Note the Drive letter Assignment will be temporary..
right click start flag > command prompt(admin)
type> select disk 0
type> list volume
type> list partition
(post a pic of cmd window)
You will see a lot of volumes without...
needless to say your post is all over the place... with that said what are you trying to do ??
remove a custom recovery image - from command prompt(admin) type
if image is registered then type
if the PC did not come with windows 8/8.1 Pre-installed
then you will need to use a Valid Activation Key....
If the PC came with windows 8/8.1 then no key is needed as the key will be embedded into the BIOS
