I'm not sure if I did this right or have the correct file. I downloaded Memtest86+ V4.00 (22/09/2009) Pre-Compiled Bootable ISO (.zip). I formatted a CD-RW with nero IN CD. I then extracted the ISO from the zip, loaded it into daemon tools and saw 'BOOT' folder. In the boot folder is 'BOOT.CAT' and 'MEMTEST.IMG'. I copied those 2 files to my formatted CD-RW. I then went into bios to boot from CD. When the pc restarted it said "Boot from CD..." waited a few seconds, and then just proceeded to laod wondows normally. Have I got the right files?
