Macbook Air Wont Reload OSX 10.5

I am trying to reload a macbook air.  The hard drive crashed and we replaced the hard drive and trying to put OSX 10.5 on it.  The CD is a retail CD and I used it the day before for another reload.  Every time I try and boot from the cd the machine reboots.  This is the same cd we used for the previous reload on a different machine and this machine with the old hard drive that had sector errors.  Obviously im using an external cd rom drive.  Could it be the drive causing it to restart

It could be an issue with the external CD drive or even with the new harddrive, which could be not compatible with your MacBook Air. I would recommend to create a bootable USB stick to get rid of CD-ROM drive and check it. Some harddrives need a firmware update of Mac to work correctly.

It is also possible that 10.5 is too old for your MacBook Air. Macs typically won't boot from a system older than the one they shipped with.

you have to use the disc that came with the mb air. download mactracker software and it will tell you exactly what is the minimum software version which your computer would take.
