Windows 8 Pro to Enterprise RRS feed

  • Question

  • Folks

    I'm struggling with this. When I am logged into Pro and installing Enterprise using the ISO installed on a USB key (similar to DVD), it simply tells me my Pro key is not valid. It basically is all MSDN and fully activated with my employer's KMS. Now, when I boot into the laptop using the USB, it again gives me an error about not finding winboot.exe. Is my best option to simply erase the HDD partition and boot with the USB or would I still face the winboot.exe problem?

    Thank you

  • Reinstall. Use correct installation DVD that is compatible with KMS.

    Program administrator should help you. Multilicense has some (limited) support from Microsoft.

    PS: Check the possibility to upgrade with DISM. Consider upgrade path.

  • What is program administrator? Also, is there a disk utility that can be installed in a usb thumb drive that I can boot off and will give me the option to delete a partition?

    In my experience, I boot from the installation media (DVD or UFD) - I never run the setup from inside the existing Windows installation.

    For Retail editions, the advice is usually to run setup from inside existing Windows, this allows windowssetup to offer "keep your stuff" and other niceties.

    But, Enterprise edition, is s different situation. MSFT assume that Enterprise admins will never do inplace upgrade, and Enterprise edition doesn't offer inplace upgrade (in my experience).

    Use a tool/utility to expand/apply the ISO to your UFD in a bootable form. Boot from the UFD. Lose everything on the computer. Re-partitioning is offered during the windowssetup routine, but note that such re-partitioning is destructive and there is no re-size feature.

    "program administrator" is the Volume Licensing contact in your organisation who has access to your VL agreement benefits.

    You cannot use DISM to perform edition upgrade to Enterprise. Enterprise is always a clean (destructive) install.

  • Guys - still getting an error. Can someone look at this image and tell me if it's indicating something from the currently installed partition (windows 8.1 pro installed) or someone wrong with the usb drive (windows 8.1 enterprise)

    winload.exe could not be found. this suggests a defective configuration within BCD, or your partition tables are at issue. Seems like you are trying to multi-boot and have the BCD configuration wrong?

  • I'm not trying to mult-boot. I have win 8.1 pro installed just fine and simply trying to install win 8.1 ent on top of it. I do that by booting from my usb drive

    Should I use instructions from this link to rebuild the mbr?

  • The MSDN ISO's for Windows 8.1 Enterprise can only be used for "clean installs" and not for upgrades.

  • It gives me the winload.exe error right away so there is no way I can reach the custom installation screen

  • Carey - I'm okay with a clean install and am booting into the laptop right from the usb thumb drive
