New install, select boot media

Installed win 10 pro N from USB.
Using all my memory didnt work previously so I Installed 10 using minimal memory. Updated, installed programs etc....browsed a bit.
Shut,down, added new memory (it worked w win 7 for years but started acting weird, not showing up,etc....). Wouldn't,boot, shut down, pulled the added memory. Walked away
Tried to boot this a.m.
Asking me to select media.
The SSD is New, Vaseky 500. Seemed to work fine yesterday. Installed the 1st time
It shows up in BIOS and boots to the drive.
Do I need to install again just to see if this a drive problem?
I,am,def booting to it
Sorry for short-type and spelling. Not a big phone typer and I cracked my screen yesterday :-/

It tends to suggest its still set to boot usb or dvd check in the bios the hd is set as first boot drive

Its def not. Even selected f8 for the boot menu. Ive pulled all drives and storage. I can only assume the drive is dead.

Most likley not dead just lsot boot sector does the bios see it ok check you havent knocked cable when changing memory

Messages are disappearing!
Everything is,connected.
Bios does not show other than in boot selection
F8 allows me to boot to it and I get the media message
Booted to USB, repair does not work
CMD is basically useless to me
I guess I reinstall

- - - Updated - - -

Cmd found the installation but when I hit Y to,add it to the boot list I get element not found

Returning the drive
Bought a Crucial. No reason the Vaseky shouldn't be working but isnt I don't have time to troubleshoot. I think,it was something with the boot loader.
When I looked at drive in hirens it showed 1 465Gb partition but no smaller 100mb partition. Is that how 10 is? I thought the OS always,created a small partition
Brand new drive. Ist thing it saw was W10 when it was formatted by the install program.

Is there another drive in the computer? Windows setup likely put the boot files in the other drive.

It did. What a pita that was! It put it on the original boot drive. Thanks for the education
