Last week I purchased a new desktop from Dell.com. The desktop comes with Windows 7 Pro 64-bit pre-installed and also came with a free copy of Windows 10 Pro 64-bit. Windows 10 came with the desktop in the form of a DVD that I have picutred here: http://i.imgur.com/Z3N84IS.jpg
Does anyone have experience using the Windows 10 Pro 64-bit upgrade disc that comes with this desktop?
Here is the product page for the desktop: www.dell.com/.../pd
I popped the included disc in, rebooted the computer, and then hit F12 to boot from the disc. The disc ran and I attempted to select the option to install Windows 10 and keep my files that are on the drive. It attempted to install but then stopped because there was a "partition missing". So instead, I then tried another option which was to wipe the entire drive clean and install Windows 10. That didn't work either because drive is locked.
Here is a link to an Imgur album I created: http://imgur.com/a/JprJf - This album includes photos I took of the Windows 10 install process so you can see what I am dealing with.
You are booting in Legacy and not in UEFI and you are also trying to do a Reset opposed to a clean installation. The Reset probably won't work without an existing Windows 10 installation.
Also Dell shipped you a DVD but it doesn't say if its TH1 or TH2... The UEFI BIOS doesn't like Booting from a DVD and its much better for you to install Windows 10 from a FAT32 formatted 8 GB USB flash drive.
To Download and Prepare Windows 10 TH2 Installation MEdia for a UEFI BIOS (aswell as Enable EUFI and SecureBoot) follow there guides:
Mention the model in your post instead of using links. You will do a clean install. Copy your personal files to external media to reinstall after the clean install of windows 10. See if this helps--
