Well there I was, rebuilding a router and having a good time when I accidentally damaged the partition table on my main Linux installation, which is a GUID partition table, or GPT. Figure 1 (above) shows the cheery message that greeted me at boot. How did this happen? I was installing Voyage Linux on a compact flash card, and while I was messing around with GParted and other filesystem tools I accidentally ran some commands on /dev/sdb, my main hard disk, instead of /dev/sdc, the compact flash card.
Linux Alix Rescue Ubuntu based live rescue and preinstallation system for PXE or bundled deployment. AstLinux - Asterisk centric Linux with firewall and VPN support CentOS - prepared image and instructions Debian for Alix (ready to use image) fli4l one disk router (in German). At this point, swap to a Linux live CD (I used Ubuntu 8.04) and let it boot to its startup menu. Choose install, and let it boot into its setup. Go through its installation steps until it asks for what drive to put it on. Choose to resize the drive and give the Ubuntu installation about 2.5GB of the available space.
I don't know exactly which operations gummed up /dev/sdb, which would be good to know. But I don't, so let us carry on. 'Press any key to exit' landed at a blinking cursor on a black screen. Fortunately, I always foil the desires of certain distros that disable ctrl+alt+delete, or make it behave like Windows and open a services manager.
I make sure that it is enabled and that it reboots the system. I booted into a different Linux installation and pondered how to make repairs. When your partition table is damaged to the point that your Linux will not boot, you have to fix it from the outside of the damaged system via bootable rescue media, or another Linux in a multi-boot installation. On a USB stick is my fave.
Any *buntu live system also makes a great rescue distro, especially on a USB stick with persistent storage, because then it remembers your settings, you can install apps, and store documents. There are no guarantees- you may be able to repair the problem, or you may have to reinstall your operating system. 
If the partition table is unrecoverable you may not be able to recover your data. So, as always, your first and best line of defense is good backups. TestDisk A good tool for repairing partition tables and recovering files is. 
TestDisk operates on both the legacy MBR and the newfangled GPT (see ). TestDisk is in most Linux repos, and on SystemRescueCD.

If you choose to create the text file, testdisk.log, it will contain TestDisk options, technical information and various outputs; including any folder/file names TestDisk was used to find and list onscreen.

In the next screen select the disk you want to repair.
