two hard drives, XP and Ubuntu, recognizes but won't boot XP
I have browsed the forums a bit and I realize this is a common problem but I am not sure if the other solutions apply exactly to my case and I don't want to chance messing anything up and needing to reinstall either OS. I have a 250 G hard drive with windows XP on it. I recently installed an 80 G hard drive and installed Ubuntu 8.10, the alternate version. Both OS are intact and work fine as long as they are plugged in as the SATA 0 port. At the Grub screen, I see Ubuntu and I also see Windows XP home edition but when I click on the Windows, I get an error 21 (I believe thats the number, I'll double check), and the error states that the disk is not found or the disk does not exist. I would like to be able to boot either OS from the start because it is more convenient than switching the SATA cables every time. I am guessing I should post some sort of parameters but I am not sure the command to use to get the parameters to pop up in the terminal. Also, I am working with 64 bit linux. If anyone can help please do, and let me know what else I should post to help solve the problem.
Ok just got home, I am going to post the fdisk -l and the /boot/grub/menu.lst contents in a minute. btw disks were connected when I first installed, I had linux as the master drive and windows as the slave. windows works when it is the master drive and linux isn't connected. linux works when it is the master drive and it doesn't care whether windows is connected or not. it recognizes windows in the grub but when i go to boot, it gives me the disk does not exist error. brb with the other things being that my linux is not connected to the internet yet.

...and remember; If it is a system which GRUB natively supports (such as Debian), you use the root command. If it is a 'foreign' system (such as Windows, but also others), you use rootnoverify.
And if Windows are on the second disk it's good to reverse the order of rootnoverify and map,otherwise rootnoverify comes after map.
hm I put that in and I'm not getting anything it says "that partition doesn't exist" now. error 22 I believe. I left the title as Windows XP home still but I don't think that matters.. everything else is exactly as you said to. any suggestions?
