Computer wont boot. Just black screen. doesnt respond to f2 or f12

Hi, Kaitlyn, I am Jeronimo, Thanks for reaching out! I'm an Independent Advisor and a Microsoft user like you.

It sounds like you’ve narrowed the issue down to the SSD or its firmware since it’s clear that your system is otherwise working because you can boot from your old hard drive, but the SSD isn’t being detected or isn’t booting properly.

-- Remove the SSD from its slot and reseat it. If possible, try a different SATA or NVMe port or cable.

-- When you power on the system, enter the BIOS (if F2/F12 still don’t work with the SSD installed, try using a wired keyboard and ensure you tap the keys immediately on Dell logo screen). Once inside the BIOS, verify whether the SSD appears on the storage or boot device list.

-- Since your old hard drive works, try installing the SSD in another computer if you have one available. This will help you determine if the SSD itself is at fault.

Please let me know the results for all 3 of this steps.

Thank you so very much for the response Jeronimo, I was able to try the SSd on another computer and get into f2 and f12. I was able to run a windows repair however it still not working and now Im getting a error on startup " No bootable devices found " Tried different Bios settings and still nothing. Not seeing the device in Bios either. Thanks for the help

Given that your SSD is not appearing in BIOS and continuing to show “No bootable devices found”, it is highly likely that the SSD has experienced hardware/firmware failure due to the power sudden interruption during the update.

You could try a firmware recovery, if the drive can be temporarily detected in another environment, but if that fails, contact the manufacturer to check if warranty its applicable.
