I will be eternally grateful! : I don't think you need to use Nortons to fix this. The disklabel program on the fixit disk should be enough. Boot with the fixit disk and then use disklabel to reinstall the boot block. The usage should be something like disklabel -w [ -r ] disk disktype [ packid [ priboot sec-boot ] ] disk = the device name disktype = the appropriate disktab entry name packid = the pack identifiaction string (up to 16 chars) priboot = block 0 boot code sec-boot = secondary bootstrap I had a similar problem and fixed it with the following... disklabel -w -r /dev/wd0a quantum200 "mydisk" /usr/mdec/wdboot /usr/mdec/bootwd This is from memory and I am not sure if it is correct. Heres a helpful tip though. Try mounting your hard disk partions after booting with the fixit floppy. This will allow you access to man pages and such. You should be able to access them even though the boot track is gone. mount /dev/wd0a /mnt Hope this helps, -- Thad Phetteplace Network Systems Analyst, Allen-Bradley Co.
