Faster boot from USB flash?

Asked by davidyorke

Is there anyway that booting of a Live-USB flash could be sped up? I've tried a Ubuntu, Xubuntu and Lubuntu and they all seem to be slow to boot from USB flash.

Generally speaking, no. But how slow is it? Also, during boot, when the screen is purple-tinted and says Ubuntu in the middle with dots below it organized in a horizontal pattern, press Escape, and see what messages are "behind" the splash screen. It's possible that some of these messages might shed light on why it is booting slowly.

Though it will wear out your USB flash drive faster (see https://wiki.ubuntu.com/LiveUsbPendrivePersistent), you might consider simply installing Ubuntu to your flash drive as though your flash drive were a normal hard drive, or doing some variation on this. Then it will not spend so much time detecting hardware and decompressing the root image as it boots. Of course, if you do this, then the USB flash drive will be less portable from system to system.

Can you help with this problem?
