I am using the Lenovo G550. It is brand new. i uninstalled the Vista and setup XP SP3 on it. Everything works fine but takes a HELL lot of time to boot up. Also when I uninstalled Vista and installed XP, I wanted to change the drives and paritions but somehow it does not let me format C: drive, so I had to install XP on another drive. Please help. I am a new member in this forum so it will take time until I understand how things work here so please forgive my mistakes. Thanks for paying attention to my problem.
