win 10 no bootable device found

[FITorion]

                                          Woke up this morning to find my computer monitor displaying the bios.      Restarting brings me to bios.  Checking boot devices in bios... no bootable devices found.      My m.2 drive is detected... and that's supposed to be the boot drive.          I put the computer to sleep last night as I normally do.  There was a pending windows update which I ignored intending to get to it today  .   I suspect the update happened while I slept and did whatever it did to break C:...   Things I've tried: I took out and put the m.2 drive back in. no luck I've found my usb  recovery drive and attempted to usesystem restore  n oluck error       0x80071a91

I don't know what's happening, whether it's my phone or the forum but something is causing my cursor to jump all over if I type too much or maybe something with the enter key as each time I try to use it the new line gets deleted... this is making posting here difficult.  Anyway I'm currently using the recovery usb and poking around in cmd prompt trying to see if there's anything on C:...  but not having any success as I'm not proficient in such things.

Ha ha... got chkdsk C: to run... evidently there is a C: for it to scan. It found no errors with the file system... then why isn't the system bootable? What now?

Your boot file probably got borked somehow.

 

I can think of nothing else but reinstall windows, but maybe there's more than will chime in and provide more solution as time goes on.

if you get it to crash 3 times and get into trouble shooting mode.. select troubleshoot , and advanced. and uninstall latest windows updates. 

 

you might have to look up how to disable the hibernation file AND fastboot to disable sleep mode... sleep is a curse and if you ask me should always be turned off(except on laptops). your system should boot fast enough to not need it and it's good for your system with a fresh boot every day..

I'm booting from a usb.  Without the usb it never gets to windows... just goes directly to the bios which does not see a bootable drive.

From the usb I've tried troubleshoot startup repair... which encounters an error and says it has saved a log file but no such file exists in the location it specifies. I've tried system restore to roll back to a previous update... that fails with the 0x80071a91 error. I've tried Uninstall updates, both Uninstall quality and feature options, both fail. When uninstall feature fails it tells me to troubleshoot > reset this PC which is not an option that exists on the troubleshoot menu.

I'm not sure what you're asking me... maybe these images will help?

press F7 and select boot.. and see what it says .. UEFI or CSM.. or both. 

 

Oh.. i see you have samsung 980 PRO 2TB... did you ever upgrade FW on those to not die ?

At the top it says uefi bios.

Csm says it's disabled.

 

I've done nothing to the ssd. But I can access it and browse the files through cmd prompt so it isn't dead...

I tried enabling csm... I could then designate the ssd as a boot drive however it still failed to boot.  I put in the usb and attempted all the troubleshooting options I'd done previously but they all failed. I've set csm back to disabled.

I'm contemplating whether to order a new ssd and an ssd enclosure so I can install windows on the new one and copy over things like my steam library from the old one...

 

What's the consensus on a good 2Tb or higher nvme ssd these days?
