'''Disclaimer: You should not try this if you don't have a good knowledge about computers, how to install, manipulate WIM images, and use DISM. I have NO GURANTEE that your mileage might not vary. I CANNOT support you if you mess something up. Before trying, please read the whole description at least once. DO IT ON YOUR OWN RISK.'''

- Follow these steps to un-wimbootify your computer: http://www.zipmagic.co/forums/viewtopic.php?t=75&p=192 (these steps are from my attempt to find a way to un-wimbootify my computer: please tell me if you have any other method without having to install a external program.)
- After a backup, Remove Recovery Partition.
- Extend your OS partition.
- (Optional, Probably not needed. I did this while bashing around to find a way to update to Windows 10.) With DISM, capture your uncompressed system image and install it using Windows 8.1 installer. You'll probably need two USBs if your WIM image is larger than 4GB; the hard limit of the size of a single file in FAT32. Format a stick in FAT32, and another in NTFS. Prepare both with original Windows install ISO. With stick with FAT32, remove install.wim or install.esd, and put ei.cfg in it. With NTFS, also remove install.wim or install.esd and put your image file as install.wim. Plug in FAT32, boot, and then right before clicking Install Now, swap two sticks and install.
- From HKLM/SYSTEM/Setup, remove WimBoot, OptimizeWimBoot and PushButtonReset keys.
- Upgrade your PC with Windows 10. I have tried with Windows Update Method.
Have in mind that even if update succeeds, drivers might malfunction.
