sorry for the miss spelled title by i was typing to fast.
I have 2 HDD one is a SATAII 160gig the other is a 80gig IDE HDD.
recently i did a disk clean up when my 160gig and figured that disk clan up wouldn't delete anything it needed. Well it did so i had to repair it with the windows cd and when i did my Main drive became the 80gig not the 160 like it was before so how do i go about switch the main drive to the 160gig?

It sounds like you need to change the jumper on your IDE drive to make it a slave drive instead of the master drive. The link below explains what I'm talking about with a picture to help you in case I'm talking Greek here. 
It's pretty easy, even without a diagram on your hard drive, you just change the jumper to one of the 3 possible configurations and soon you will find the right one, with no chance of damage if you don't guess right the first time.

Near as I can tell, you may have selected the wrong drive to repair/install windows on.
Normally, in systems that have both IDE and SATA drives installed, the system will check the IDE drive(s) for a boot sector first, and then the SATA drive(s). If you install(ed) a system on the IDE drive it will (normally) try to boot that drive first. It's also possible that, even if you repaired/installed on the proper drive, the boot sequence got reset by the repair/install procedure.
Many of those systems have an option in the BIOS which will specify the boot drive. To check, normally you need to press a particular key during start up to get into the BIOS. This key is most often DEL, but check with your computer/motherboard manual or website if DEL doesn't work.
Another work around that sometimes works, is to put the IDE drive on the secondary IDE port (if the motherboard has 2 IDE connectors) - preferably as a slave to the CD/DVD drive.
