i had done using the way it has shown in the first post of the topic
firstly by Copying the .raw file to an USB stick using SUSE Studio Image Writer and that was succesful
the second one i can't understand
"Boot the USB drive and install"
becoz when i tried nothing happened it starts booting the windows 7 only
one thing more to tell i think there is changes needed to be done in bios setting but i can't find that setting to change here i am posting the images too could u tell how could i change the sata controller to ahci in my bios there is no option
my bios is BIOS: Phoenix - AwardBIOS 5.13, v6.00PG
