AFAIK, it's hardware issue to boot from flash drive greater 512Mb. Some time ago I've use 256Mb bootable flash drive with BartPE installed. All systems (that support flash boot) was able to boot from that drive. From 512Mb flash drive only half system be able to boot. From 2Gb flash only 2 system can boot.
Is it possible to transfer sims 2 to a pen drive? I have a new laptop , its an Advent 4211 , its only small and doesn't have a CD Drive , I was wondering if its possible to transfer the sims 2 game to a pen drive/Flash Drive to install it on my new laptop because it has a socket for one.
