Grub starts as expected but when I choose Drdos it gives following 
information:
rootnoverifi (hd1,0)
chainloader (hd0,0)+1

Cannot load DOS! Any key to retry.

Any key reboots my computer.

Did chkdsk /f and had a lot of bad sectors.
In the meantime it is repaired. My command.com autoexec.bat and config.sys are 
fine as are the system files.

Did fdisk /mbr but this fdisk does not react to /mbr.
Get the normal fdisk menu with as choice number 5 write mbr new or something 
like that. Using this choice it says it has rewritten the mbr but my grub 
starts as usual and the choice in grub still gives the same answers.
Did a sys a: c: which went okay. An it is sure the first partition of the 
first drive where drdos is positioned.
