Grub errors when removing extra HD
I installed and ran Linux dual boot for a week. Great stuff. When removing an extra hard drive, I variously get Grub error 21 and 17. It was the second (IDE 0 slave) that I removed. Windo$ is on IDE o master and Ubuntu is on IDE 1, slave. How do I remove a drive and tell Ubuntu Linux to ignore or reconfigure for that missing hardware?
