Hey guys, after messing around with the recovery disks for ages for my tablet and getting nowhere (getting bounced back and forth between the UEFI and Legacy bioses), I decided to pursue another solution for installing Windows on the tablet. You cannot install a stock Windows 8 Pro disk or USB drive, because the CD Key for Win8 is hardcoded into the tablet. You can however install an OEM version, and I was able to get it working. Here's what you need to do:
Download the OEM version of Windows 8, I doubt I can link it for you but here's the information you need:
(make sure, whichever source you get windows from, you verify the SHA-1, you can find programs to do that via Google just look for an MD5 SHA utility).
Once you have your file, create a bootable USB drive (thousands of tutorials online) and copy the contents of the ISO onto the drive.
Now, boot your Tablet into BIOS (hold power+windows key for about 4 seconds when booting). Go down to the 'boot' option and switch to Legacy BIOS mode. Make sure your USB drive is before your HDD in the boot order. Save and Exit the bios.
It should reboot and install Windows 8 as expected, HOWEVER, you may have a serious issue with graphics once it finishes installing the files (I could only use about half the screen). This is remedied by simply installing the VGA drivers from Acer's support site, but it might be a bit tricky to do if you do not have an external monitor and some type of input device (it is doable though, I did it with just the tablet, but I had to switch from portrait to landscape a few times to get different parts of the screen to show). Don't bother changing the resolution, that won't fix it.
Install all the other drivers from support (Wifi for instance won't work, so you need to have another computer to get the drivers on, but presumably you did for the USB drive anyway). Other than that, system runs great, and there is absolutely 0 bloatware!
op thanks alot for the guide. i have it plain vanilla win 8 stock running. the process of installing was fast from beginning to start screen only took 15 min. acer process recovery took almost 2hrs. so if you are type of people like to do clean install frequently or don't like preinstalled apps, or have lost your recovery dvd, or don't have external dvd drive and like stock win 8, this process is for you. on the side note, i have my boot as uefi option, secure boot disable. put the iso mount files on 4gb bootable usb, along with wifi driver, bluetooth and what ever your backup apps and you good to go. remember to backup important files first
it never asked me to enter keys during setup. however you could use belarc advisor to extract the keys from w700. if you have not back up info regarding sn and the like, product keys, now is the time to back up if have not register the tab. write down info or better yet make a text doc and email them to your self for safe keeping. try that keys you extract from w700 see if it works. it should have no problem at all for the keys are burn within bios.
I'm sorry but I don't quite get you there. After plugging in the USB, I set up the boot order and reboot into the Setup. At the Setup of Windows 8, it suddenly popped out an error saying 'The product key does not match any windows image available'. I cannot proceed with the Setup and force to reboot. It is weird since it never prompted me to key in any product key at all.
i would double check the iso again. my guess is the image either is corrupted or different image like enterprise edition is on there. i download mine over mydigitallife forum. under windows 8 section, they have a sticky post name the officicial windows 8 repository . you would look for windows 8 rtm english 64 bit. its a 3.3gb. need a torrent client like utorrent to download btw.
any edition keys may not match.
this iso should have no problem with the keys.
iso can have many images in there, depending on the install.wim file that mount from it under sourses
use command dism to find out.
anyway i would try download that iso and boot again. it should be fine
this iso contains both win8 and win8 pro . install.wim index 1 is pro , index 2 is win 8
