Without a OS there is no such things as safe mode, safe mode is apart of Windows, so without windows installed there is no Safemode. After BIOS you should get some text and then pop in the OS disc, without the OS your not going to be booting into anything. Remember, Vista is a DVD, so you will require a DVD drive not a CD drive (I believe there is a CD version, but it has multiple discs, though I might be wrong). Also, if you have a SATA drive there have been a few reports of SATA not wanting to run OS's. Also, if you bought vista, did you manage to buy the upgrade version or the clean install version. Double check the hard drive is installed properly, if it still doesn't work switch to another IDE or SATA cable and try that.
