Yeah, i didn't think it would happen to me but today i used the command dd if=/dev/zero on the wrong harddisk. Instead of a disk with media files i wiped the first 623 MB of /dev/sda where my operating systems are installed.

 > s dd if=/dev/zero of=/dev/sda bs=1M
Password: 
^C594+0 records in
594+0 records out
622854144 bytes (623 MB) copied, 7.59657 s, 82.0 MB/s

As you can see i noticed my mistake after roughly 8 seconds and aborted the process.
Obviously, the complete MBR was wiped. Same goes for my boot partition /dev/sda1. Luckily, sda2 is a Windows partition which - i guess - is irreparable now but i didn't use it anyway.

So, the real question is, do you think I can save my linux installation? If so, how would you proceed?

The way I see it, all I'd have to do is recreate the MBR and reinstall the kernel + grub. I'm mainly concerned about the MBR as it would have to be exactly the same as the one i wiped, wouldn't it?

There are threads like these. Search the forums. There are certain apps that can help you recover the data.

Try gpart, it might be able to find everything needed to recreate the partion table.

As for your /boot, just reinstall the kernel and grub.

Edit:

If you have no important partion like /home or whatever on the disc, then just reinstall. Probably faster.

Before trying any radical partition recovery software, I would make an image of what you still have using dd_rescue.
