You can see which partition on each disk is marked as bootable from the fdisk outout i.e. the one with '*'.
1. When you say (hd0,1) it means 1st partition on 0th hard disk. So in your case you will have to specify (hd1,1). 2. You can see that root partition of your installation is specified with UUID. UUID is a unique identifier for every hard disk partition in your system. I am not sure if partitions on a USB disk will have same UUID everytime you boot. But if it is the case then you can boot into Ubuntu and find UUID for all partitions with command 'ls -l /dev/disk/by-uuid/'. 3. It is possible to dynamically specify kernel, initrd, and root in grub instead of trial and error on menu.lst. When you see grub menu of Ubuntu, press 'c' key. It will give you a command prompt. You can then give commands root, kernel and initrd. After that give command 'boot'. Ifthe parameter you have provided are correct it will boot in Mandriva. If now you can reboot machine by Ctrl + Alt + Del and try again. This way you won't have to boot in Ubuntu everytime. Once you have found correct values add those to your menu.lst Hope this helps.
