> jest jakiś sposób aby pendrive w systemie zachowywał sie nak CD?

Jest:
http://isostick.com/

The isostick shows up as two drives: an optical drive and a flash drive.
It lets you "load" ISOs from the flash drive into the optical drive-sort of
like mounting a disc image in *nix, or using DAEMON Tools in Windows-except
computers think it's a real, physical optical drive, with no software
required.
Because it's all in hardware, you're able to boot from isostick directly.
If you can boot from a USB CDROM, then you can boot from isostick.

Sam mam ogromna ochote na ten wynalazek, ale:
- ciezko go dostac
- cena :)
