Unmount the /boot and make sure there are no other submounts on / then try your remount again. If it works then remount /boot on top of it.

hey every one
i got the solution without using the cd . thsi is what i did
1. logged in emergency mode
2.mount /dev/sda2 /boot
3.cd /dev
4.mkdir tmp
5.cp /boot/initrd(xyz).img /dev/tmp/.
6.cd /tmp
7.mkdir tmp2
8.gunzip -v -S .img /dev/tmp/initrd(xyz).img // THIS WILL UNZIP THE FILE
9.cd tmp2
10.cpoi -id < ..initrd(xyz) // THIS WILL EXTRACT THE INITRD FILE
11. make the fstab in etc directory thus extracted here
12. edit the init file to mount the / partion and the swap partition
13. find . | cpoi --create --format='newc' > /dev/tmp/newinitrd
14. gzip newinitrd // this will create neinitrd.gz
15. cd ..
16. mv newinitrd.gz initrd(xyz).img
17. cp /dev/tmp/initrd(xyz).img /boot/initrd(xyz).img
18. reboot the system
19. work as you want
