Good news my friend, install drivers, do not install Antivirus at this stage, then follow this procedure: https://technet.micr.../dn621983.aspx and later this one https://technet.micr.../dn605112.aspx or ask cdob to help you make a new Boot Wim install.ini compresed image Windows way (using dism) to free several GB in your device, ask him if installing Office before making the compresed image can create any conflict with Wim Boot, if not it's a good idea to do it.
I remember I read somewhere that when running an antivirus in a Wim Boot system, the antivirus extracts all files from the install.wim so you lose all the benefits from Wim Boot, even worst you end up with a full instaled system + a compresed image of it, so think about this.
I have the drivers if you need any just tell me in order to upload it because can't remember the link. I'm thinking in buy a MeGoPad T01 so when I saw the drivers just downloaded them, think from a chinese dealer page about the device.
When i get more time ill try to create a boot Win and ask for help. Thanks.
I forgot where i found the drivers link but i think it was from where i bought it.
