What happens when you try? Any error messages? Do you just get a blinking cursor?

I'm going to assume that this is an MBR partition table and that those partitions are actually 1, 2 and 3 (that is, the first three primary partitions). Did you install grub into the MBR of the drive? The installation should have asked if you wanted that. > but the weird part is when i press "F10" and select harddrive to boot it > amazingly boot. it seems like more of a BIOS issue but the same system is > booting fine with a 250GB drive. BIOS can only ever boot from one device. Typically, this is defined in the "Boot Order" menu, somewhere in the BIOS menu. The normal procedure for a BIOS with several options is to try the various boot devices in the specified order and look for a valid boot loader. So, for example, it'll check the floppy drive and boot from the disk there if there is one. If not, it'll check the CD drive for a disk. Finally it'll look at the hard disks. Now, if it finds a valid boot loader on the first disk it looks at, then it's not going to look at the other disks. The boot loader it looks at is, of course, free to do whatever it likes. So a common thing to do is put GRUB onto one disk, nominate that as the "master" (i.e. the one that the BIOS jumps to) and have that copy of grub either load operating systems from other disks or to chain-load the bootloader on the other disks. > any idea what is going on. > Thanks, > MYK >
