Good morning everyone.

Yesterday evening I was having computer problems so I decided to do a clean reinstall of WIndows 7. I cleaned out some partitions and then tried to put WIndows 7 on the fresh partition. The process began and then I got a mesage saying that Windows cold not format a partition on disk 0. This error occured while preparing the partition selected for installtin. Error code 0x80070057

I also get a message when I restart the computer saying ¨Missing Operaing system¨ I´m guessing that that means I cant log in to fix this problem

Please help fellas.

How many partitions do you have? I would delete all partitions... repartition if realy needed and reformat / install

Do you need the 2 partitions?

would 1 partition do better?

what is the best size of the partition?

Delete all partitions.... when booting off of the Windows DVD it askes where do you want to install windows.... you can click on advanced and remove your partitions there. that is also the spot to repartition the drive.
