Why is the iso I create with nLite not bootable?

[Win]

I burned it at the slowest speed possible as well and when restarting the computer with the cd in the drive it just sits there saying booting from cdrom or whatever it says extractly

In the bios I did make sure to set boot from cdrom first.

Whats the problem please?

Sometimes it happens naturally, a bad burning or whatever. However, in your case its probably the CD burning software you used, sometimes you need to set a special option somewhere to make the CD burnable, look around and try and find it, and if that doesnt work, who knows, post back then with whatever options your using in nLite, it might be that...
