ISO help

[Michael_]

Hey, so I made an All In One Vista.ISO but it turns out the file is too big. 4.6Gb on a 4.7Gb disk.. How can I split the .iso and burn half and half on two seperate dvds and make them bootable, like using disk one then inserting disk two..

How is 4.6 larger than 4.7?

^ Arent the 4.7GB discs like 4.3 after formatting or something?

There is a margin the disk is prohibited to, it is to protect the laser from burning past the disk face, sub chanel data takes up unreported space. ( not sure on that last)been a while sinse I've used discs.

I have used DVD shrink on video's that are too large to fit on a dvd disk and every one of them shrink to 4.35 gb's. I think that's the max you can burn onto a dvd disk

Discs false advertise.
4.3gigs is the true size.
Is there any way I could split an ISO in half and use like Part 1 and Part 2 dvds?

You can try a dual layer dvd disk if you have a DL burner. Many dvd burners have the capacity to burn a dl dvd, you'll need to check the burners specs first. That should get you better than 8gb's

You could always just use a USB stick. It is a little more complicated (use diskpart on windows vista, 7 and 8 and rufus on xp) but not that hard. Plus once you have the USB it is more convienient and faster than the traditional optical alternatives.

I could do that, but some computer don't boot from USB.

"Unetbootin"works pretty well to make a flash boot able.
