Windows 10: boot disk

What key do I use to use boot up disk

Can't safely remove external disk

In reference to the steps of your suggestions:

• The issue is specific to the particular disk and it started after I've used the disk to save the System image backup (created with the Control Panel > File History tool).
• I didn't disable any windows Service. I'm just wondering if there is any to disable.
• Safe boot with networking, or clean boot doesn't resolve the issue.

Thank you.

 

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!

 

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.
