Fedora cannot be bootup!!
 

The machines was hang so I only did the hardware reset the machine!!

After that the Fedora cannot be properly boot up. It prompted me the msg "data intergrity check", it can't finish the process until 50%. Finally it shown as following:
Duplicate or bad block in use!
/: Duplicate blocks found... invoking duplicate block passses.
Pass 1B: Rescan for duplicate/bad blocks

How to fix it?

I cannot stop the automatically boot menu, so i cannot type chkdsk....

hi
you may try to boot in rescue mode
and then check your hard disk.

yes i can used by following instruction:
How to use Fedora Core 2 Rescue CD, to gain root user access?
01) Read me:
01a) General Notes
01b) Only applies in True Console mode
02) Insert Fedora Core 2 Rescue CD:
02a) At boot menu, press "Enter" Key
03) If you do not have Fedora Core 2 Rescue CD, insert Fedora Core 2 CD 1:
03a) At boot menu type "linux rescue":
03b) Press "Enter" Key
04) Follow the instructions until you see the command prompt:
04a) sh-2.05b#
05) To mount existing linux installation:
05a) sh-2.05b# chroot /mnt/sysimage
06) You have root user access now
07) Done!
