I'm building a PC for my buddy and everything has gone well until I tried installing Windows. The hard drive (ripped out of his old HP system) is not allowing me to install windows on the hard drive.

The hard drive was factory partitioned by HP in 4 parts. The largest one, partition 3 which has 914GB on it, is where I chose to install windows on. It is not allowing me to do so though.

It shows this error message when I try to install it:
"Windows detected that the EFI system partition was formatted as NTFS. Format the EFI system partition as FAT32, and restart the installation."

What should I do from here? Thanks!

Personally I wouldn't re-use an old hard drive unless it's less than a year old. Hard drive technology changes rapidly and old fashioned hard drives are slow anyway. SSD's are faster and you won't use anything else once you switch. Is there any data on the old hard drive? Choose Advanced or the other option and delete all the partitions if you don't need the data. You have to create a new partition if you delete the old partitions.

The hard drive is less than a year old so it's fine and I did what you said by deleting the volumes. It worked our just fine, thanks!
