Burned ISO disk worked on 1 machine, not other

[Hankm]

I burned the ISO file to dvd with no problem. I installed the 64 bit RC on one machine without incident. However when I tried to install it on the machine nwith the beta I was unable to boot. Any suggestions why or alternatives

I was spoiled by the ease of the first install.

Did you get a Boot error code: 5 when trying to boot the DVD? Is so read post #14...
