Disk boot failure after removing old Vista partition

Thank you for the reply, muchomurka! As I indicated in my post, I have already tried all the steps you suggested to no avail:

- I cannot choose startup repair since the computer does not boot from the installation media
- I cannot use command prompt since the computer does not boot further than the POST screen
- I have disconnected and tried out all hard drives individually.

Since I had Win 10 up and running a few hours ago, I can say with 100% certainty that none of the hardware is faulty.

The real mystery is, how come the system won't boot from any media without an empty disk containing an old Vista boot sector being on top of the boot priority list? And which steps to take now that I've cleaned this disk and it does not exist anymore?

Would appreciate any ideas and pointers!

 

Boot from old hard drive

The motherboard of my old computer died suddenly and so I bought a new computer. It has two 1TB HDDs on RAID 0 and comes preinstalled with Windows 10 Home. I wanted my computer to boot from my old 120GB SSD from my old computer but it doesn't seem to recognize it as boot drive. It was working perfectly with my old computer.

I can view files from the SSD and so this confirms that it is working. The boot partition is marked active.

I tried changing the boot hard drive in the bios but in the bios, the only two options shown in the boot menu are

• Windows Boot Manager (Intel Volume1)
  
• CD/DVDRW
  

After searching online, a website suggested swapping the Sata of the old hard drive with that of the new one. I tried even this but this didn't work either. It gave me the error "boot disk not found" and in the boot menu, the only option was "CD/DVDRW".

For Reference :

Motherboard : ASUS Z170 PRO GAMING

All Hard Drives Run GPT.

Any other solutions?

 

How to make a flash drive boot disk?

I still suggest Ultimate Boot CD, I have the link a few posts back. You can boot to DOS and run the flashing utilities right off your hard disk, it's safer too because you don't have to worry about a corrupt floppy.
