Hello Folks, I am so dazzled that my boot disk is crashed after electricity goes off. When I start the PC , it says that Not found any [active partition] in HDD DISK BOOT FAILURE, INSERT SYSTEM DISK AND PRESS ENTER so I have tried to Fix it with fixing CD. To open with it and I see the partitions and files in the disk, I try the command that fdisk -B -b /boot/boot0 /dev/ad0 disklabel -B -n -b boot1 -s boot2 /dev/ad0 But the system doesnt boot.. Any idea on the problem, how can I solve this problem.. Regards, Murat Ustuntas ustuntas@bimel.com.tr
