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):
gdisk says it to be a protective MBR, but '-l' switch doesn't print any partition:
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.

Humm, the conversion from GPT to MBR by gdisk is a best-faith attempt only according to the man page. No guarantees, especially if there were no free blocks between the partitions.
You could try the -c option to load the backup partition table but I suspect that it will contain nothing.
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.
rying it this way, because I can't handle the slices for the second hdd. If there is someone on this forum who can help me out of that misery, he would really save my digital life in this digital ocean.
So not giving up, reading several times the manual of gpart. But the best hint in all that... (0 Replies)

Hello,
My hard drive was formatted with GPT. It is part of a volume group and has two logical volumes on it. Is it possible to convert the drive to MBR? If so, how would I got about doing it? I know there are programs out there that do it, but I have volume groups with LVM's so I am wondering if... (1 Reply)
Hi,
I just built myself a new machine which has an ASUS motherboard with is UEFI based.
I noticed after I installed Fedora 17 that my sda is MBR and my sdb is GPT:
sda is a ssd drive. Should the ssd drive be GPT or is MBR okay?
sda is 60Gb drive. (3 Replies)
