WIndows could not format a partition on disk 0.Missig operating syste

[forgotenm]

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.
