I have damaged my VDI file when trying to resize it. I have mistakenly specified the new size in bytes instead of megabytes - I wanted to resize it up to 200GB (from around 60GB). This is the command that I executed:
VBoxManage.exe modifyhd msu.vdi --resize 214748364800
(VirtualBox 5.0.0.10, Windows 7 host)
It failed with RPC_S_SERVER_UNAVAILABLE (I don't have the exact error code anymore).
After that the vdi file fails to load with VERR_VD_VDI_INVALID_HEADER.
Unfortunately I didn't create a backup and there are no snapshots.
I have found some info on this forum on how to fix the header and after I have done that, VirtualBox now recognizes the vdi file but I can't boot into the guest OS (Ubuntu) - it says:
FATAL: No bootable medium found! System halted.
When I boot into GParted Live with the patched image attached, it shows the whole space as unallocated. CloneVDI says that the patched image has corrupted block table.
Is there anything that could be done to either fix it or at least retrieve data from it?
The volume was set to dynamic resize and before the failed resize the file was about 50GB, now it's around 100GB.
The header before the fix looks like this:
