So, I got a direct download of Windows 7, I burned my .iso to DVD and tried to boot from that. I get 'no bootable CD in Atapi CD-ROM'. In my boot sequence I get no option for DVD, only CD, I don't know if this is the problem. It shows up as a DVD-R drive in BIOS. I can boot my XP installation CD ok, just can't actually install from it.
However, I also tried booting from a USB device, specifically an 8GB Compact Flash card in a USB card reader. Then all I get is 'Y∞∞Y∞∞' and nothing more. I can boot fine from a USB pen drive with puppy linux.
Don't know where to turn from here, guidance would be much appreciated, please
