Hi Been having trouble installing xp on my Acer One, just hangs on Windows startup when installing (see other post). I fully understand the process and thought i woud try another pc instead of my xp one. I tried a Vista pc but after formatting with PeToUSB it will not allow me to go any further as it states the USB needs to be FAT32 or NTFS ? I have checked the USB and it was FAT. BUT when i also checked with my xp pc that was also FAT but allows me too proceed ?? The stick is generic 2G so should be ok. Any thoughts on this ? COuld this be my problem ?? If anyone could check their USB stick to see what it is formattted to after using PeToUSB i would be gratefull. Cheers
