booting from cd/dvd to install win 10 os UEFI
HI guys,
wondering if i can get a little help of what im doing wrong
So, ive had my windows 10 pro dvd that i had burnt for a few years now, and has always worked fine on booting up in legacy mode to install win 10.
So my HTPC was still on win 7, and getting a new 3 tb hard drive for it, ive decided nows a good time to put win 10 on it.
However this time i want to install in UEFI mode which will be the first time for me.
My boot options have been preset in bios to EFI ATAPI DVD ROM, EFI USB, LEGACY SATA 0 HDD, LEGACY ATAPI DVD ROM, LEGACY USB STICK
My issue is, when i select boot override , UEFI ATAPI DVD ROM doesnt come up on the list as if the dvd i have isnt bootable, neither does EUFI USB
So with ultra iso, i made an iso file from the dvd i had, downloaded Rufus, and made a bootable usb flash drive using the iso i just made and options in rufus,rufus transferred this to my usb stick.
Tried that, and now the options to boot from EUFI USB come up and OS istall started up and installed in EUFI mode
Thats all and well
But why didnt my dvdrom show up in EUFI mode?
Does a bootable disc/flash drive have different boot files for either MBR or EUFI? I noticed rufus has alot of bootable options, maybe they are to do with legacy and EUFI boot?
I know DVDs are almost a thing of the past, however i do prefer them over a flash drive for os install.
Any advice why im doing wrong?
Thankyou for the help in advance
