I tried to format my Sony Vaio (svs1511n3es). I formatted the partitions first and then proceeded to the instal of the win7 cd. The cd had a problem so I had to restart and put another one. Since then, I get a message "Operating System not found". The computer does not boot from the cd or the flash drive (both fat32 and ntfs) although I changed the boot priority from the bios settings (F2). I put a cd of win7 32bit and I successfully installed the windows (I still do not know how the cd was recognized). But I want x64 as my laptop will work better on that. I tried to format again and still I get the message of the operation and the cd/flash won't load. It is just like I do not have a cd or flash connected to my pc. What should I do ? I tried many things like changing the bios settings (uefi or legacy) etc.
