How would i go about from executing a batch file that finds your primary drive letter. Its like %SystemDrive%. But how would i execute that so it echo's it back to me?

Everything you need is in your post.

@echo off
Echo You primary drive is %systemdrive%
pause

not what i meant , how do i GOTO that drive if its not C:\

i cant cd\ to it.

If you have e.g. E:, you just issue the command:

E:

that 'logs you to E:'.

Then you can 'cd' around that drive all you want.

That help?

Or

cd /d drive:\path
