How do I install Lion on new flash drive?
Mac Pro, OS X Mountain Lion (10.8.2)
Flash Drives, thumb drives, USB drives are generally not fast enough to run Mac OS X in a reasonably satisfying fashion.
If you really mean a SATA Sold State Drive, it installs the same as on any other internal drive.
If this does not address your question, you need to pose a question that is focused on exactly the issues you are encountering.
You select the drive you want to install on during the initial install screen.
To my knowledge Os x does not support booting from USB media. This may only apply to USB 2.0 and down.
You can install and boot from an external Firewire drive. When running the installer, select the firewire drive from the list of possible install locations and continue.
To boot from firewire, hold option at startup and select the external drive from the list of drives.
For an emergency pocket size boot device?
Or something else?
Or, do you want to setup the Lion Installer for clean or reinstalls on flash memory card, which is what many use?

USB on Intel Macs has always supported booting, that is what MacBook users have had to deal with. With a Mac Pro you have four internal drive bays, Firewire, and all of those are more suited and capable.
Old thread, never die do they.
Thanks for the info, and the links to this information. I have been approching a new reinstall with my I-Mac after 3 years of operating system issues that included a repalceent of the HD by Apple on a recall list that was created after 2 years of use. No cost to me. Then again the system results showed up again starting with a in ability to safe boot. Then morning where the computer tell me it can not find the start up disc. Goes to recovery partition each time I turn on the system.
I am limited to a Wi-Fi internet use that on reinstall attempts goes wrong. Last reinstall was by a certified computer apple store where in 3 Months the system strated acting up.
I did complete on the release of Mt. Lion a DVD 4.7 GB down load. What I do have is a the origional HD in a Fire Wire incased, inables me to use as a computer, and access the internal drive and user info. BOTH
so hope is I can intall this was. Any suggestions would be appreciated.
Thanks

Actually it does, and at various times, I've set up USB 2.0 flash drives with Snow Leopard, Lion, and Mountain Lion installed with various utilities (e.g., Disk Warrior) to boot from in emergencies. I've also done that with ML and Mavericks using a partitioned USB 3.0 flash drive for a rMBP and it not only works but is remarkably fast in the USB 3.0 port.
Intel based Macs can boot form USB as well as from FW (and Thunderbolt for newer Macs), Power PC based Macs (G3, G4 and G5) can only boot via installed dive and FW, not via USB

Not sure where in that was the specific question?
If you have thunderbolt and wifi only run some ethernet to thunderbolt cable and adapter.
If you just save the installer package before use, move it somewhere, that alone helps.
And start with making a clone (Carbon Copy) of your existing system - your safety net, so you can restore.
Upgrades of OS X over older one has its problems, as you found. A clean install is simply safe fast and easy and let Setup Assistant finish it up. And move data to another drive if possible.
Whether flash or a physical mecanical hard drive, all you need is a small partition and it does not have to be flash card unless you want to.
Considering this thread is now OLD it is sad that it gets reopened. There are new updated reviews on Mavericks but basically the same.
