New user here so please forgive my ignorance. Installed Parallels and want to install WinXP. I've created a flash drive containing XP installation by using WinToFlash utility over on my Win7 machine. The flash drive containing XP should be bootable at this time. When I try to create a XP vm in Parallels it looks for a Primary Master IDE drive, and CD-ROM (which I do not have), and lastly a floppy drive. How do I force Parallels to look for the WinXP install files on the flash drive?
