short thing: I've done something I didn't know what happens; bad thing: I did it with my partition table.
My OS is Ubuntu 10.10. I've used GPT and now want to convert it to MBR with gdisk.
I started gdisk, chose 'r' for "transformation options" and chose 'g' to "convert GPT into MBR and exit".
Then I rebooted. Now all my programs tell me something other:
fdisk says the following (language is german):
Gerät boot. Anfang Ende Blöcke Id System
/dev/sda1 1 121602 976762583+ ee GPT
gdisk says it to be a protective MBR, but '-l' switch doesn't print any partition:
GPT fdisk (gdisk) version 0.5.1
Partition table scan:
BSD: not present
APM: not present
Found valid GPT with protective MBR; using GPT.
The kernel doesn't seem to detect anything, only sda* thing is /dev/sda.
partitionmanager says that there is no valid partition table.
Now, what should I do? Stupid thing is that I missed to make a backup of my first sectors before.
Remember, the only thing I want is to be able to read my partitions on sda again and to have an MBR on it in the end.

Yes, that is the best plan. Glad you had a backup. It is my opinion that utilities such as gdisk should not attempt to automatically convert from MBR to GPT and visa versa. Too many edge cases where things can go wrong.
