Unfortunately, recently, my C drive got corrupted and I had to format the whole partition and reinstall the untouched windows 8. which kinda broke the OEM recovery partitions link with windows. There are 2 recovery partition in my laptop which includes install.wim and boot.wim. I need help in applying those images on my C partition so I could have OEM provided OS installed. I don't have any USB=>16GB nor external HDD, So, installing windows from internal HDD is only my option right now. I already tried applying the install.wim using gimage and the applying process was successful but after applying the install.wim and running bcdboot commands and even bootrec commands it couldn't make it bootable. The install.wim file includes further 2 folders inside. I am pretty confused what is purpose of these 2 folders. They are named as  and ? The 1st folder shows simply standard windows files while 2nd folder shows windows files + OEM installed apps folders as well. Here is what I already tried: 1. Imagex/gimage (Not being able to make it bootable after applying image) 2. Replacing install.wim +/ boot.wim on standard windows installation files. (This gives error during installation after copying files, right on installing features stage) 3. Applying install wim location for refresh and reset functions to work without installation media. (Despite that, Refresh and reset functions still demands installation media to continue) Any idea what am I missing? Any help will be highly appreciated! Thanks in advance!
