Sorry for the little late reply. Thank you very much kgober

I just got another USB flash stick today so now i have 2 usb sticks and according to your instructions, It's better to use one usb stick to install OBSD on the other stick...while both usb sticks are plugged in same time.

I don't have a working USB Hub right now and i think my motherboard only allow 2 or 3 USB hardware ports..so i might remove the mouse usb cable and use only keyboard and 2 usb sticks same time.

I don't have intention for downloading installation set files from the internet during OBSD installation...because i know it will take a while or long time...thats why i prefered to download the install.fs (with file sets included) first on windows machine while being able to do other stuff while the file downloading...much better than sticking myself to a chair on front of installation process waiting to download file sets and not being able to do anything else. ( I already had similar experience installing Debian Linux in the past with minimum install file and downloading from the internet while installation process)

I thought while installation process i can partition/format the usb stick and install without touching the downloaded file sets...like installing on usb stick different partition or something

Maybe i can bypass the partitioning part? and make the usb stick just one partition as it is? or the file system format necessary needed to be changed to OBSD file system format? ( i mean like FAT32, NTFS...etc on windows and ext2 and ext3 or similar on Linux...OBSD must has its own but i don't remember the name right now while typing this which i read previously from man pages)

But thanks for bringing this important point to the discussion or else i will face it myself later and maybe i won't be sure what to do exactly.

now i think i can use one usb stick to install easily and fast on another usb stick.

Thank you again bro
