Where do you want to install Windows?

It shows Disk 0 Partition1 100.0 MB (PRIMARY)message* Windows cannot be installed to Disk 0 Partition1
It shows Disk 0 Partition2 100.0 MB (PRIMARY)message* Windows cannot be installed to Disk 0 Partition2
It shows Disk 0 Unallocated Space 465.6 GB * it will not allow me to install here gives me error code

Can someone help me fix this I was trying to make partition 1 C:/ and partition 2 D:/ ?
What should I have indicated when it asked how much MB to allocate for 1st partition? *note this is for a 500GB HDD WD WD5000aaks

Delete the two 100MB partitions. The reason it can't install on those is because 100MB is nothing.

It is completely up to you how you want to partition your hard drive. You can just delete those partitions and select the full unallocated space and the Windows 7 installer will automatically partition and format the entire drive for you.

Thanks Fadedmaster, did that deleted both but was not able to use Disk0 unallocated it give me an error 0x80070005, then it says "The selected partition requires at least 8437 MB free space." The only thing it will allow me to do is to create new partition. Is it because I chose the Advanced method instead of single partition, will the single option create a C:/ and D:/? Can I start all over again or will I have to do to partitions manually now? Is there recommended MB amount for the 1st partition which I guess will be the C:/, and will I have to also do 2nd partition for D:/ or will it do it automatically if I do it manually?

For future reference, you don't have to post a new question. You can just reply to the existing one.

You can split the drive up however you want it. Look at it like a pizza. You can cut it into however many difference sized slices you want, but cut it up too much and it's almost impossible to work with. No one wants a blended pizza.

At any rate, if you want to split it in half, then you want two partitions at 250GB each, or 256000MB.

1GB = 1024MB

Format each of them as NTFS. Although I am concerned as to why you would get such an error message if you are selecting a 500GB drive... Are you sure you deleted all partitions so that you just had 500GB of unallocated space? And are you sure that's what you selected?

I also get that error, but mine is different (slightly). I purchased a WD5000AAK for my a6700y HP desktop PC and it says Disk 0 Unallocated. No partitions listed as stated above
"shows Disk 0 Unallocated Space 465.6 GB * it will not allow me to install here gives me error code"

Same error code too. Does this drive need Bios Drivers or something? Maybe that's the issue here.
