I'm going to assume you have Windows installed and want to createa linux partition. For some reason Windows should be installed first because it will mess up the master boot record if it is installed second. If you have linux CDs, your should have a dir on the 1st one called /dosutils/. Look for a file called fips.exe. Fips will shrink your Windows partition without destroying the data on it. You will need to clean it up 1st and run defrag. Then disable Virtual Memory until after the linux install. Some distros of linux will create the linux partitions it needs automatically. You will just have to tell it to use the unused space. When asked where to install lilo or grub (boot loaders), choose the master boot record (MBR) or you will have problems. I knowthis is kind of brief, but it should give you an overview of what needs to be done.
