Windows 10: failed to boot from selected device

so, im trying to boot from a USB, but when ever i go to boot from device then select the USB it says cannot boot from this device, anybody know why?

:)

 

confused about selecting boot device


This is good information but I am confused about step 2 below. Wouldn't I need to select whatever device, USB or DVD, the install media is on at this point and not how I want the final install to boot?
Thanks,and sorry for dragging up an old post but it had most of the info I was looking for.

It is up to you whether you want to install Windows using MBR or GPT and you need to set the option in the BIOS for MBR or GPT style installation.

Having said that. Here's the steps:

1. Disconnect all HD/SSD except the one you will be installing Windows
2. From the boot menu, Select #1 for GPT or select #2 for MBR to boot up the Windows Installation
   Attachment 29081
   NOTE: The screen is an example and might look different from yours
3. Once the Windows Installation started. On the first screen, Press and hold SHIFT Key + F10, a command Windows will popup then type:
   - diskpart
   - select disk 0
   - Clean
   - Exit
   - Exit
4. Click Next to continue.
5. Select Custom
6. Select the first unallocated partition and click next. Windows will create all needed partitions to install Windows 10
7. Follow all the rest of the instruction to complete.

MBR installation:

1. 500MB System Reserved partition
2. C: Drive

GPT installation:

1. 450MB recovery partition
2. 100MB EFI System Partition
3. 16MB MSR partition
4. C drive.

Can't boot from DVD drive

Is your controller in RAID/AHCI modes? If so, the DVD drive will be listed as a separate device in the list of available boot devices, not as "CDROM". Remember that when setting boot device priority. Otherwise, read the manual to see which hotkey during POST brings up the boot menu that lets you select which device to boot from. Even here, the drive will be listed separately, and not as "CDROM".
