Is it possible to recreate a corrupted partition table from the installer data
in /var/log/installer/
I accidentally overwrote 5MB over /dev/sda - the partition table and
my /boot partion when
creating a bootable ISO on a USB key.
I have 1 * ext3 boot partition and 1 * encrypted lvm root partition.
Below is an extract
of the partman log and the cdebconf log.
Is anything special required for crypto parititons?. Does the lvm
partition start from cylinder
62 or cylinder 31?
If I run cfdisk -z, I am guessing that I need
sda1, bootable, primary,type-linux,size-62 cyl,
sda5,,logical,type-lvm,size-rest-of-disk
I have been suspending/resuming the laptop since yesterday. A boot
will definitely
fail since the kernel has been wiped. If I create and format the boot
parition I will re-install
the kernel.
I have backup up all data on the laptop, so if recreating the
partition fails I will re-install.
Thank you
Jeff
