boot - Is it possible to install an OS on USB flash memory of 4 GB - Ask Ubuntu
i asked install os on usb while have flash memory of 4 gb. there os product nice gui ubuntu in can boot usb? if so, how install , boot usb?
from our wiki:
notes size
1 gb enough live usb flash drive made 'cd size' iso file. unless have 1 gb drive, recommended 1 @ least 2 gb, hence general recommendation above.
2 gb enough 'cd size' iso files many not 'dvd size' iso files.
if want persistent live system decent size casper-rw storage, need @ least 4 gb (2 gb possible, might run out of space).
if want installed system need @ least 8 gb (4 gb possible lubuntu, might run out of space). in beginning of 2014, seems there no fast pendrives below 16 gb. if want fast system, install pendrive performs in test, if 'bigger necessary'.
so answer yes, limitations; not on size on speed (4gb usb slow). 8gb recommended , 16gb preferred.
