[SOLVED] Is it possible to restore partition table with system inside?
Hello,
Using parted, I have changed the partition table of /dev/sda from gpt to msdos by mistake (instead of /dev/sdd).
/dev/sda is an arch install (sda1 --> /boot, sda2 --> /).
I am writing from my second arch system. I have back up and can reinstall easily, but is there a quick way to restore the content of those 2 partitions? Or is reinstallation the better way?

It is possible to re-create the table manually but you would have to know the exact sectors at which the partitions start and end.

It did the job! Used as root from another arch installation on another disk, It recreated the altered GPT table and my Arch boots fine.
testdisk is available in Arch Extra Repository. Cool software...
Thank you.
