Hi kbz1960 ,
I have used used a usb stick (about 2GB+) to get over this problem.
I have 64 bit win7 on a laptop and decided not to grub that system
So plug in the usb stick, boot PCLInuxOS x.x and install it
At the partitioning point, pick the usb stick as /boot and at the end select the usb stick as the booting device.
Now without the stick in Win7 boots and with the stick in pclos boots.
Just make sure the boot order is CDROM first then usb device then hard drive.
It works very well
