bootloader problem


when my system starts up, I see a flash of "GRUB" on the screen then system cycles thru trying to find a system disk...bios is correct....I think there are remnants of a grub bootloader on the hard drive.....any way to delete this info....even re-formatting didnt seem to get rid of it.....

This is a windoze command I believe but I have used it and it worked for me.
fdisk /mbr

If this is a currently running system, as in you do have an OS on it, look for a different means of removing then.
hope that helps.

What are you trying to achieve ???.
If this disk is selected then apparently it is the BIOS primary boot disk. If you are installing, just put the CD drive ahead of it (in the BIOS boot order). As part of the install you will need to take the option to install to the MBR.
This replaces the loader code, and all this evaporates.

dd if=/dev/zero of=/dev/sda count=1

Will overwrite the MBR with zeroes.

You can do the command from a boot cd like knoppix.
