    Unfortunately, the only legit Microsoft download, other than MSDN, that I know of won't accept OEM keys. You would have to resort to something like bit torrent. That has the risk of the ISO being modified in a bad way. The hash codes for the official Microsoft ISO's are available on MSDN. You just can't download the file without a valid subscription. If the hash code for the file you get from where ever matches what Microsoft says it should be, then your file is likely safe to use. The OEM embedded key is actually in the BIOS, not on the SSD. Product Key - Find for Windows 8 < I know you can't do this at the moment but I'll post it for info purposes anyway. If your laptop came with Windows 8.0, an 8.0 ISO should read and use the embedded key. You could do this though, Activate retail Windows 8.1 with Windows 8 Product key.. Install 8.1 with the generic key, then use the script in the other link to get your BIOS key and activate with that. It will save you from doing the store update to 8.1. Assuming you can find a clean 8.1 ISO.

    The only other wrinkle that can happen is if your installed version was the "single language" version of 8.0. If it is you need the single language ISO to be able to use the OEM key.

    These are the regular ISO's as listed on MSDN

    Windows 8 (multiple editions) (x64) - DVD (English)

    File Name: en_windows_8_x64_dvd_915440.iso
    Languages: English
    SHA1: 1CE53AD5F60419CF04A715CF3233F247E48BEEC4

    Windows 8.1 with Update (multiple editions) (x86) - DVD (English)

    File Name: en_windows_8.1_with_update_x86_dvd_4065105.iso
    Languages: English
    SHA1: 54B8572556B316A6BECE54C5033564E3296F5951

    The single language ISO's are not listed for me on MSDN so I don't know what their file names are?

    One doubt, is an OEM ISO download file applicable the same way to all the manufacturers installations?

    I mean - I could get HP OEM Windows 8 ISO file for download by browsing their forums. But will this be all that's needed for Asus OEM Windows 8 installation, so that it gets activated from its BIOS product key?

    HP experts say that this ISO is legal for a long duration now. But due to recent Microsoft restrictions over Windows 8 OEM iso for downloads, they're not sure if it is legal now also.!

    I don't know? It may have stuff added by HP. In the past each OEM had custom files added for the OEM activation to work. Those files aren't needed with Windows 8 but there may be other stuff added. I create custom install media for each of my PC's. I add a $OEM$ folder to do it. I add stuff like OEM logo's and system info to the System page. I add PID.txt files too so I don't have to enter a product code during setup. My laptops came with 8.0 Core but I install 8.1 Pro with my TechNet keys to save time and avoid having to do the store upgrade to 8.1. I haven't actually seen an actual branded OEM DVD of Windows 8 or 8.1 so I don't know what the OEM adds to it. There may be drivers added etc. I have yet to see an actual Windows 8/8.1 DVD of any kind. Nobody I know has bought a Retail copy so I can't even compare it to my MSDN ISO's. Wish I knew more about it.

    EDIT: If it has a $OEM$ folder in the sources folder, and or an EI.cfg file or PID.txt, deleting them should strip it of all the added OEM stuff. Then it "should" work just like any other Windows 8/8.1 ISO.

    Okay, that clears up the confusion. I hope I could test this with the OEM ISO of HP(from HP forums) in my sister's Dell machine after the specific changes have been made. Have to wait a bit long for that though.

    Thanks alphanumeric

    Well, now I have a new problem. I used Parted Magic and I found 5 partitions. I list them below:
    1) 100 MB Healthy EFI System Partition. I think this is normal.
    2) 900 MB Healthy Recovery Partition
    3) OS (listed as drive C
    4) 450 MB Healthy Recovery Partition
    5) 20.01 GB Healthy Recovery Partition
    Can I assume that if I assign a drive letter to it (the correct drive) that I can restore to factory fresh? The question is, which one is the correct one, and what are the others?

    For factory recovery it would be 20gb one .
    For me HP recovery drive (D:\) was around 20gb itself.

    You don't have to assign a drive letter to the recovery partition. As far as I know doing so won't make any difference or change how it works, it will either work or it won't. The factory recovery utility should already be pointed/coded to the correct partition.
