My headless powerpc box can't boot from CD because it hasn't CD device. It only has USB drive. Furthermore, it can't boot with an usual system rescue image installed on USB stick, because it uses uImage. I tried systemrescuecd ( http://www.sysresccd.org ), gparted live to boot with, but without success. I think I have the possibility to use serial console only. There I can run parted but don't know how to fix with it the problem I made. > Otherwise, there is always testdisk or your backups. I just installed testdisk and try followings: Select a media: >Disk /dev/sda - 500 GB / 465 GiB - WDC WD5000AACS-00G8B1 Disk /dev/mapper/bubba-storage - 2256 MB / 2152 MiB - WDC \ WD5000AACS-00G8B1 Disk /dev/dm-0 - 2256 MB / 2152 MiB - WDC WD5000AACS-00G8B1 >[Proceed ] Please select the partition table type, press Enter when done. >[Humax ] Humax partition table Hint: Humax partition table type has been detected.
