how to install TC on desktop already running windows by using pen drive and using tinycore.iso file??
please help!!
First off, can your computer boot from a CD? Can it boot from a Pendrive? If not, you can stop here.
It seems to me that you are not familiar with burning an ISO file to a disk. You need to do that first.
If you are really new to Linux, TinyCore may not be the ideal Linux to start with.
Then you need to read through the installation instructions at the TinyCore main website.
