Hello B.Pruthiviraj,
I'd like to help you solve your issue, but beforehand I need more informations about it:
1. What is the used version of VirtualBox? 2. What is the exact version of your host system? Linux or Windows? Which distribution? Which Release? 3. Did other guest OSes work in your particular VirtualBox installation? You may try to download and try a current version of TinyCoreLinux from
http://distro.ibiblio.org/tinycorelinux/4.x/x86/release/tinycore-current.iso
4. If applicable, send your VirtualBox VM configuration.
Regards
