Are you sure it blew away the install, and didn't just munge the 
bootloader?  I it happen to me where I told F8 anaconda to ignore 
/dev/sda (which has F7 and Windows on it) and only install to a USB 
stick on /dev/sdb (blank flash memory stick).  When the install 
finished, it was supposed to have written GRUB to /dev/sdb, but I 
found that anaconda wrote grub to /dev/sda, but got it wrong so that 
the only thing the hard drive booted to was a blank screen with the 
words "GRUB" in the top left corner.  It was simple to restore the 
bootloader by using a F7 rescue CD, chroot /mnt/sysimage, grub-install 
/dev/sda.  The F7 install, Windows, etc. were fine after that.
