bootable lion usb for a different computer

[mwm5053]

I have a Mac Pro with 10.7.5 (lion) and made a bootable usb in case of trouble. I have recently bought a MBP that 10.5 on it (bought it used) so I wonder if I can use that usb to install lion on MBP any ideas would be appreciated.

Thanks

Dont get so tangled with the legal stuff (it is important, but no so worthwhile to the problem in hand). After all, they are Macworld

The key here is: Did one computer come with Lion pre-installed, and the other with an earlier OS? If YES, then a USB key created on one computer will not work on the other one. This is true for Mountain Lion too.

The obvious question is:
If you put the USB flashdrive into the MacBook, can you do a "switch-boot" and boot the MBP from the flashdrive?

Try that, and you will have your answer.

As long as the MBP is capable of running Lion, yes... that will work.
