Puppy on USB - boot says "missing operating system"
 

I have done no mistakes.

My BIOS boots from the USB.
I downloaded puppy 5.0.1 iso and burned it to a cd.
Then booted from the cd and used install to set it up on a usb.
It didn't work ...

I am a complete newbie ..... please Help me

Also please suggest some other distro for a usb

What do you mean when you say "it didn't work"? Are you able to boot to other USB devices?

Yes i can
 

my bios supports usb boot

dont know why puppy linux didn't boot

It definitely recognizes the device as bootable ..... but shows the message " Missing Operating System"

when you put puppy on the stick did you give it the flag that names it as a bootable device?

i dont know if this helps but on my box every time i want to boot from usb i must choose that option in boot set-up. it sounds more like you didn't make it bootable
