Hi Alb
The reason you are getting a command prompt is because you did not install the extensions required for a GUI.
Create a partition for Tinycore. Then, using the install utility included with CorePlus (
http://tinycorelinux.net/install.html).
Select Existing Partition
DO NOT Mark Partition Active
DO NOT select Install Bootloader
complete the installation.
In menu.lst, change root (hd0,0) to point to your Tinycore partition.
Open the /boot/extlinux/extlinux.conf file in the Tinycore partition. Copy the initrd and kernel paths to menu.lst. Copy
everything starting from quiet to the end of the line to the kernel line in menu.lst.
Reboot.
