Windows 10: No Bootable Device Found After Fresh Install

I recently clean-installed Windows 10 after finding myself booting into a black screen with cursor post-login after having ran the memory diagnostic tool, and later getting a "No Bootable Devices Found" error after various unsuccessful repair attempts.


Clean-installing Windows from USB worked fine, although it ran into some errors in the first attempt. By the second attempt it installed quickly and easily, and booted into Windows with no problem, although it seemed to be running rather slowly, which I attibuted to drivers/etc installing in the background.


However, when attempting to restart after confirming that Windows was working properly and had the necessary drivers, the system shut down fine, powered on again, got to the Acer logo and watched the balls spin for about ~30secs until it powered on and off again, once again displaying the "No Bootable Device" error.


Standard fixes from across the web didnt help; resetting my bios settings to default, adjusting the boot priority and ensuring "Windows Boot Manager Intel Data_Volume" is at the top, attempting automatic repair, booting to safe mode which also gives me a "No Bootable Device" message, running the bootrec commands which all either worked to no effect, gave me "access denied" errors, or displayed that zero Windows installations were found, none of those commonly listed fixes helped.


After troubleshooting for hours, i attempted a third windows install, which went by withiut issue and booted me easily into windows when completed; this time, I didnt try to install drivers in my own and made sure to create a system restore point, then attempted rebooting... Sure enough, the same cycle occured after powering back on and "No Bootable Device" is staring me in the face again.


I've heard some explanations saying this will happen if you installed Windows 10 in legacy mode instead of UEFI, but I've been able to confirm my Windows installation *is* UEFI, and my system bios's boot mode is correctly set to UEFI.


I do have an Intel Optane supplemented hard drive, and I've been curious if that could be causing problems, but so far i havent found any evidence for or against that being the case...


Chkdsk was successfully ran on my drive at some point during all this, but no errors were found.


At this point I feel like I've exhausted all my knowledge and I'm unsure what else to try... I appreciate any help you can throw my way, and I'm willing to provide any information I may have missed

Multi-bootable USB

Hey guys from TPU, couldn't find any specific thread pertaining to the question asked on title. As mentioned, I'm trying to create a bootable USB, but with many specifics boots available.

I've been trying to create one with multiple boot device including one that enables me to run Windows 10 directly on the USB Thumb Drive but to no avail.

The list of bootable images i'm trying to create are

1. Windows 10 (A full OS running from thumb drive)
2. Windows 10 ISO (Bootable disk image for fresh install)
3. MemTest86+

Have tried YUMI or UUI from the website USB PenDrive Linux but as this is my first time, i don't know how am i screwing up or am doing it right.. Anyone got a rough idea on a step by step guide? Thanks!

 

Bootable Vista Installer

I have a friend who has a Vista Home Premium key (from the bottom of his laptop) and his HDD crapped out so he ordered a new one. His repair disks didn't work and neither of us have CD's with a large enough capacity to store the files we 'found' on the interwebz, so I'm trying to install it from a bootable USB.

I got up to the step where I successfully turned the USB into an active partition, but I ran into a problem the moment I needed to access the boot sector.

Can someone kindly walk me through the steps?
