Kingston.com is not an official SanDisk site and a “Compact flash card” is not a pen drive. And your tiny font is hard for people to read.

I know you’re trying to help people who post but giving incorrect information doesn’t help them.  Flash drives have been being made bootable for at least a decade and no manufacturer, including SanDisk, has told users they can only used as storage devices.

Get a good nights sleep and you will feel better in the morning. :smiley:

BTW A good source for free portable apps that I have used on occasion is http://portableapps.com/apps  And they guarantee them to be virus/malware free.
