There are a number of reasons why this will happen - Install Mac OS onto WinTel machine, Install OS for IntelMac on Power PC mac clone, Install Win7 onto WinTel machine that has not enough RAM or Hard Disk space to enable the install. Simple question, complex answer
The installation CD of the new OS should be bootable. Boot the computer with the disc in, and choose to install the OS. It should give you an option to clean install, and format.
You can install a server OS on it.
Unfortunately no. The mac OS is specially designed to install on macontosh computers.
When you want to install a new OS, you want to make sure that you backup all your data, make sure your hardware and software is compatible with the OS, and that your computer meets the minimum requirements. Save
install os x lion
dual boot allows you to install the new OS without disturbing the old one so you can boot to either OS.

It improves performance because it wipes the data from and old OS install so the old files dont corrupt the new OS install. Having a "clean" drive also improves laoding speeds because it doesnt have to figure out which files to boot with.
The hard drive is not configured to your PC's settings. Re-install the OS on the new HDD.
Yes, but depending on the OS you're looking to install you may have to delete all files you have on your computer: this is especially if you're installing an older OS. You should insert the OS disc and boot your computer up from it.
If it's the original disk (grey?) that came with yourcomputer when it was brand new then yes.If it's a retail disk, then if your computer meets the minimum system requirement then yes.If your computer came installed with Lion brand new then it might, but it's not supported by Apple. If Apple had not updated the new computers when Lion started being shipped then you still have the older architecture so you could still boot to an older OS, at least as far as the OS that those computers originally came with.In other words, when Apple ships a new OS and dosen't update the computers at the same time the computers will only ship with the new OS from then on.
no it will download a viruse and destroy your computer
