Windows 10: Booting From DVD with Win 10 & UEFI

Hello, I tried to add a DVD to boot sequence but I couldn't find an option for this. I tried Dell's recommendation but they indicate that hardware might not be recognized by the system. I did use the DVD to install Win 10 initially, but it doesn't show up. Can someone explain how to add a DVD to boot sequence for a Dell Inspiron 15 using Win 10 with UEFI or Legacy if that is an option? Thanks

:)

 

How can I boot into Windows 10 DVD from UEFI?

I have a laptop which has a weird boot issue (the issue is - hopefully - not relevant to this question; and I'll post a Q about it later; but in short, on boot, it goes into Windows Boot Menu with 4 different Windows installations listed, any one of the 4 leads to "installation failed".

When I tried to boot the laptop (Gateway NE 522) with bootable Windows 10 install DVD; it never booted into DVD - instead, it showed "Boot Manager" with only HDD "Windows Boot Manager" as an option, when in UEFI mode (the image isn't of my screen but my screen looks nearly identical except for HDD name being different).





Troubleshooting steps taken:

• I went into BIOS setup and ensured that under UEFI mode, DVD-ROM was the first drive in boot order. No effect.
  
• However, when I switched from UEFI to Legacy mode, DVD booted without any issue (that didn't help me, since none of recovery options worked; and installing Windows on the correct partition failed since it was GBR partition).
  

How can I allow booting into my DVD from UEFI mode?

 

UEFI vs Legacy boot mode

Yep, UEFI mode with Win 10 loading I get the Asus logo.

IIRC there maybe an option within motherboard UEFI to disable the Asus logo but not looked into it. On another forum I have read that what logo you get at Win 10 loading is the easiest way to know what bios mode OS is in.

If system is booting in legacy mode - you get Windows Logo.
If system is booting in UEFI mode - you get OEM logo.

Above also applies to Win 8 but not Win 7.

 

Win 10 booting not that fast

Thanks for that ! My Win 10 is installed in UEFI mode on a gpt SSD.
Searching a bit more I found this : How Can I Configure Windows 8 Ultra-Fast Boot UEFI GOP?
So : no gop compatible graphic card = no fast boot
This explains why my laptop is faster: it is from june 2015 and my graphic card from 2012 ...
Will try to find a custom vbios for my GC.
