I just downloaded and installed Parallels 4
Then it's time to install Windows XP

no matter which method i go through, it tells me:

"No Systemdisk. Booting from harddish
Cannot load from harddisk.
Insertsystemdisk and press any key"
when i press any key it thinks and give me:
"no boot device is available, press Enter to continue"

boot order seems right. my virtual machine in enabled...
i need to get this working for school in a few days... what do i do?
