No mounted file system
When I am trying to install the GNS3. It is giving me an error i.e.. No mounted file system. I have tried every possible way which is given here but still not able to resolve it.
1) I have tried the /System/Library/Extensions/LexarFilterScheme.kext but the files not there.
2) I have also tried the Disk utility but still the issue is not resolved.
Please provide a good solution for this. I need this to fixed ASAP.
