[lubuntu] Problem with Grub menu and bootloader

view story

http://ubuntuforums.org – I have 12.04 on a SATA hard drive and 10.04 on a PATA drive that is controlled by a SATA/PATA PCI card. When I boot-up, I get a grub2 menu that lists both operating systems, but if I try to boot into 10.04, I get this message: error: no such device: [followed by the long uuid code for the drive on the PCI card.] error: hd1 cannot get C/H/S value error: you need to load kernel first But if I then Ctl-Alt-Del, I get the GNU Grub menu from the PATA drive with 10.04 and it also lists both OS's and I can boot into either without a problem. When I restart, I get into this grub menu, (Hardware)
