[ubuntu-in] Need Help - Disaster during some fiddling with partitioning tool -

[Ramnarayan.K]

Ok so the good news is that i have my data back.

This is what i did

Booted of live Ubuntu 7.04 DVD
Added local repository that i have on an external hard disk

installed testdisk

ran its analyse and search deeper option

then asked it to write the MBR to the first sector

it managed to find the two partitions where my /home and /shared (vfat
data section shared with windows) is and now these are accessible

It has not managed to redo the ntfs win os and the windows recovery
partition or the Linux Ubuntu OS "/ " section.

But once i back my data up will try and redo this

Read Moz's second mail and will try something like that.

thanks

ram
