i have a windowsXP OS, but the system down and i can't open it, so i decide to install ubuntu. i installed it in my USB how to force the computer to boot and read from flash and install the ubuntu, without opening the windowsXP system ??
On my computer sign ACER, and before booting OS you should press F12. Then you will say Boot menu - choose Hardware and then FLASDISK.
But it dont have to work also on your pc.
