two operation systems

[lhbrisson]

i had a virus that rendered my computer useless. i re-installed windows,reformatting the hard drive and loosing all the data. i'm OK  with that. now the recovery drive has two operating systems and its memory is full to 90% capacity. i don't know how this happened. i thought the first ( infected ) operating system would disappear with the reformatting of the hard drive. I NEED TO DELETE THE FIRST O/S. CAN ANYONE HELP?

1) You did not format or the drive would have been completely erased.
2) I suggest you start again. Boot to the OS CD or DVD, choose the format option, format the drive, then install the new OS. If you want to be 100% certain you can also delete and then recreate the system partition prior to formatting.
3) Just a terminology correction if I may: Memory is ram. I believe you don't mean the "memory" is full to 90% but rather the hard drive is almost full.
