Ok, so I figured out what to do with the prior problem (duhh, only had to search it

)
Then, I got this: Still waiting for root device.
So, I looked around and found several solutions, which I tried one after the other. Since nothing worked, I decided to erase the install I had on a IDE Maxtor 80GB Harddrive and try again on a Partition of my SATA 500GB Harddrive. I went into disk utility and wanted to format the 20GB of unallocated space I had made, but in the process of formating, a warning popped up which said that the Disk Utility lost contact to the Harddrive or someting. I then rebooted and got the following error:
Reboot and select proper boot device or insert boot media in selected boot device.
Now, I searched the internet and found many results on this problem, but:
Unlike other people out there, when I go into BIOS and then Boot settings, it still detects all of my HDs. I have tried setting bios to default with no result, I have tried disabling other devices in Boot Priority, except the SATA where Windows XP is installed. No result.
Something wierd that I have noticed is that I can now see a Floppy Drive in BIOS Boot Priority settings, though I don't even have a floppy drive.
I have tried inserting Windows CD and repairing. I did Fixmbr, and reformatted the partition that was destined for Leopard, I did BOOTCFG /SCAN and it found the Windows install and told me there doesn't seem to be any errors with it.
Now, the reason I'm asking for help here is because I thought somebody might know why this happened in relation to installing Leopard... and, of course, how I can fix it.
By the way, the next step I was going to do is install windows xp on the IDE MAXTOR 80Gb drive and try with that, but I don't feel that it's going to change much.
Thank you for your help.
