Solved How to get windows 8.1 to recognize missing partition?

Specs: windows 8.1
I Cannot gain access to a partition after windows 8.1 install. For a rebuilt PC, I installed windows 8.1 on a 1TB drive. Prior to the install, I created a 100GB partition. After the install, I notice that the remaining 900GB storage space is nowhere to be found. Windows doesn't recognize the rest of the drive. I've never done this before. How do I fix this?

You probably need to google, if your motherboard bios will recognize a 1TB drive

✔ Best Answer
If your bios is seeing the drive OK then the 'missing partition' is probably not a partition at all. It's just unallocated space. You need to have a look at the drive in disk management:

Agreed, once in Disk Manager you just need to right click on the unallocated space and partition it then format it to NTFS.

You have to be a little bit crazy to keep you from going insane.

For starters, 1TB = 931.32G

"Prior to the install, I created a 100GB partition"

Why would you do that? By creating the partition before installing Win8 rather than during the installation, you avoided having the System Reserved partition created. Was that deliberate? If not, I suggest you start over. Boot off the Win8 disc, delete all current partitions, & then create one new one using all the drive space. Windows setup will automatically create the Reserved partition as part of the process. Repartition the drive after Win8 is installed by using EaseUS Partition Master Free Edition.

Thanks for the help guys. I haven't built or rebuilt a computer since 2009, and I really don't know why I created the partition prior to install--silly mistake. I was able to find the rest of the drive/unallocated space through disk management as recommended--feels like I dodged a bullet.
