Blank recordable DVD discs (DVD-R and DVD R) can be recorded once using a DVD recorder and then function as a DVD-ROM.Rewritable DVDs (DVD-RW, DVD RW, and DVD-RAM) can be recorded and erased many times.I don’t totally agree with the above assertion of being able to boot from any drive when holding down the “option” key. I reformatted machd drive, it shows only the recovery options.. But, both didn’t show up in startup menu and holding c does nothing…I’ve tried this several times and when I get the menu, the drive I am attempting to boot from (which does have an operating system on it) does NOT appear as one of the bootable drives. All I can get is recovery partition in startup menu and is osc utilities menu once I select recovery option….When this cannot be determined, the disk burn fails.

Rather than hold the Option key, you could instead just press & hold the C key if you’re booting from a CD or DVD disc.Download the 6Gb installer and burn to USB flash as described elsewhere. Power on Mac mini Press and hold option key Wait for disc boot selection menu THEN plug in your installer USB stick – it will be recognised and provided as a new boot option. Unfortunately, come reboot time, you gotta do this again otherwise it reverts to rebooting from the previous OS :-/ Well, that’s my limited experience so far…is a digital optical disc storage format invented and developed by Philips and Sony in 1995.Multiple factors can cause the error, but it is most likely to occur because the CD/DVD burner is not able to determine the Optimum Power Calibration rate.The Optimum Power Calibration rate is a test that is run before burning a CD or DVD to determine the optimal laser power needed to write the CD or DVD.I can install Linux Mint 17.2 using my Mac Book Pro and move the drive to the server.It works 100% I also have Linux Mint 17.2 on my Mac Book Pro. Can only download the installer app on a current Mac from the Mac App Store app.
