Windows 10: Selected boot device failed.

While booting up my HP laptop this screen pops up. Hp disk diagnose failed before this and after that it showed this screen.

:)

 

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

   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.

reboot and select property boot device

You need to set your main Harddrive which has your Operating System on as the first harddrive to boot, if have more than one harddrive.

open Bios
boot priority
Select the OS harddrive as first boot drive , If not sure switch between them
Set correct time and date if wrong
Save and reboot

If not sure on steps , give the Make and model number of motherboard and can assist you.

Hopefully no damage to the HDD
