C Drive "/dev/hda1" accidently used in dd command at "of=" switch

M D · 04-24-2007, 04:27 AM

I have accidently used /dev/hda1 i.e. my C Drive, in dd command as "dd if=/dev/hda9 of=/dev/hda1 bs=512 count=1" where /dev/hda9 is "/boot" and /dev/hda1 is C Drive.
Now I can't able to boot my system. Kindly any one who knows how to resolve this problem, Please help me...

Nasty accident. I'd try simply reinstalling the bootloader, for example Grub, with grub-install:

Code:

man grub-install

.

Thanks, but my C drive has Windows Xp Installed, D has Windows 2003 Enterprise and /dev/hda9 10 11 has Fedora Core.

So ....
can you boot the system or not ???.
Which boot-loader are (were) you using ???.

Chances are you've only destroyed the Windows XP volume or partition boot sector, I suppose this could make it so you can't boot depending on your setup. Here's a page that describes how to restore it: http://pcsupport.about.com/od/fixthe...bootsector.htm
Some more information about your setup would help us give you further instructions

Which bootloader do you use? LILO, GRUB, or the Windows one?
When you say you can't boot your system, what actually happens?
