U disk to install win7 system when you need a lot of storage space is the most appropriate

1, the General simple U disk boot disk words basically do not need how much memory, after the completion of the production of the boot file about 10 trillion, so the U disk does not need a very large, ordinary 1G u disk can be;

2, if you still need to put the system files to the U disk installation, according to the size of the system file to judge, if it is WIN7 system files, it will require a lot of space, 4G u disk more appropriate;

3, U disk Startup disk after the completion of production, just a few small files, ordinary capacity of the U disk (1G) can meet the requirements, but basically everyone's u disk capacity is 4G, 8G and 16G, so users do not need to deliberately buy a large volume of u disk to make, the province is too wasteful.
