I mI'm using Debian Wheezy hosted on W7 in Virtualbox. I needed to enlarge root partition then added a new virtual disk to virtual machine. Doing the steps mentioned belove bringbelow brings me to grub prompt. Shortly i;I:
- Added new virtual disk
- Formatted and mountmounted
- Created PV
- Added to same VG with root partition
-  Extended root partition LV with lvextendlvextend
- Resized the file system.
 Everything donewent well and iI checked that with df command and lvscan but after reboot couldntI couldn't boot the system. What point ihave I missed and how to recover the system? Thanks for any advise.
