Hi, I'll preface this by explaining that I'm a novice, hobby builder with practically zero understanding of Linux. In fact the problem described below occurred while I was installing Ubuntu in an effort to learn about Linux based OSs. My system has Windows 7 Home 64 bit installed on a WD internal hard drive and I added a second internal drive (Seagate) with the intention of installing Ubuntu thereby having a dedicated drive for each OS. I attempted to install Ubuntu 10.10 from a dvd on the blank Seagate drive but musn't have disabled the WD drive in the bios because I ended up with both OSs installed on the WD drive and a GRUB boot menu now appears immediately after my mb splash screen. Both OSs work perfectly and I'm content with the result except if I disconnect the Seagate drive I get a GRUB error and am unable to boot either OS. What I'm wanting to do is remove the Seagate drive from the GRUB boot menu so that I can install it in another machine. I'm also novice in command-line protocol so will need to be walked through the procedure with my hand being held. 8) Included below are screen shots of the boot menu, edit page and error page. If anyone can assist me it would be greatly appreciated.
