my last eset update made that i cant boot anymore

[Guest Dennis F]

Hello. So since the last Eset update where it told me to reboot my pc. windows doesnt wanna start anymore. it always says an error occurred while booting. also safeboot doesnt work. there probably is not a way to go back one version if i take my harddrive to another pc. so what do i do. just save all important files and reinstall everything again?

Are you able to boot from a Linux live medium for instance? If so, please check if the file C:\Windows\System32\drivers\edevmon.sys exists.

[Guest Dennis F]

from looking with the cmd thingy in the boot assist it doesnt show. only errdev. sys

If you can access Win 10 recovery environment which it appears you can, did you try the Automatic Repair option? This usually fixes most boot issues.

i tried that 2 times but didnt work sadly. tried booting up a few times already and always the same. i also cant access the safety start 

[Guest Dennis F]

the recovery option doesnt work. i tried it 3 times and i also cant do the safe start or whatever its called. always gives me the message that an error occurred while booting with the smiley

[Guest Dennis F]

gonna remake my whole pc again. i saved all valuable files with linux mint and hope eset doesnt cause problems again

[Guest Jeysie]

I ran into the same problem myself, updated ESET, restarted my computer, now it won't boot due to an "inaccessible boot device" error, and none of the recovery options in Windows worked to do anything. The file Marcos listed is definitely missing, which tracks with how the log from the failed Startup Repair showed a driver was missing. (Which initially confused me because I couldn't remember updating any drivers.)

I fear I might have made things worse trying to fix things as a result since I was clearly chasing the wrong issue; I'm going to have to see what the Dell folks say when I send it in to them.

It's disappointing, I've been happy with your program for years now but it's not reassuring that simply updating it could break my PC this thoroughly.

Do you remember what version you upgraded from? Could you try copying C:\Windows\System32\drivers\edevmon.sys (e.g. from another machine or from the ESET install/drivers folder) after booting the system from another disk?

Is eamonm.sys there and only edevmon.sys is missing?

Do these drivers exist or not?
C:\Program Files\ESET\ESET Security\Drivers\edevmon\edevmon.sys
C:\Program Files\ESET\ESET Security\Drivers\eamonm\eamonm.sys

Also please provide C:\Windows\INF\setupapi.dev.log.

By the way, what ESET product do you have? Do you remember if you have upgraded to v15.0.23 from an older version than v14.2?

[Guest d3adf1sh]

THIS HAPPENED TO ME TOO!!!  I was SO pissed ...  i just finally starting to get back to a normal working environment and all my installed programs are gone all my bookmarks in browssers.  completely lost access to my telegram account,  man i really am pissed plus my eset licence it says is no good and i bought that as a 3 year plan over a year ago.  this is ridiculous.  i'm on win10 and was on all the latest updates.  i glad and also upset it wasn't just me.  this is like 2+ days of my life i'll never get back.

 

couldn't boot into safe mode or anything.  luckily i keep all my user files on a seperate drive but this is pretty ridiculous

mine was from 15.0.22 to 15.0.23 from what i remember.  after trying every option i could multiple times i just did a reset on mine so i doubt any of those old files are still on here.  but i can check anything you want if you think they are there.

Did you change the product to ESET Antivirus from ESET Internet Security or ESET Smart Security Premium in the past?

no just like normal said it needed to restart to finish an update like it has a million times before.  no big deal. then nothing. it would start to boot windows and hang on the splash screen with the little thing would stop spinning.  never made it to desktop.  have to hard reset after that.  even tried to let it go for like 5 min but it never boot.  there is a windows.old folder incase there's any files you would want me to try to find

[Guest de3thf1sh]

also my windows version was enterprise 1909  and now it's updated to 21h2  so not sure if that had anything to do with it.

Please answer my questions:

Is eamonm.sys there and only edevmon.sys is missing?

Do these drivers exist or not?
C:\Program Files\ESET\ESET Security\Drivers\edevmon\edevmon.sys
C:\Program Files\ESET\ESET Security\Drivers\eamonm\eamonm.sys

Also please provide C:\Windows\INF\setupapi.dev.log.

If C:\Program Files\ESET\ESET Security\Drivers\edevmon\edevmon.sys exists, please copy it to C:\Windows\System32\Drivers. After booting to normal mode, collect logs with ESET Log Collector and provide the generated archive.

Did you have Device Control integration enabled?

are you talking about in windows.old or in the new installation because i already did a nondestructive reset and installed a trial version of eset in the new installation,

or were you talking to everyone in the thread?

 

edit:  i found the setupapi.dev (txt file) and everything in it is from 1/20 when i think i originally had the problem.  do you want me to post it?

Yes, please upload it here. However, you have posted as a guest and I'm not sure if they have permissions to upload files.

This might significant to this borked boot issue.

Microsoft is currently force updating users of unsupported Win 10 versions to 21H2.

One theory here it was a case of both bad luck and timing. The Win 10 feature update had already been downloaded, silently installed, and awaiting a system restart to be applied. The user did the restart when prompted by the Eset ver. update.

I don't think so, I have the regular Home edition and my OS got cranky and refused to have the 21xx update ever work so I was still on whatever the most recent 19xx edition was.

Those files are there, and I personally tried what you suggested but am still getting an "inaccessible Boot Device" error.

Of course I tried a bunch of other things to see if I could fix the problem before narrowing in on this being the original cause, so it's possible I accidentally broke something else on top of it, sigh.

i had signed up for an account so i sent it to you in a DM.  it's too long of a text file for me to make a screen shot.  if you want to start a regular thread for this issue let me know.

i think they may be encrypted system files you may not be able to access through linux or something, but i don't know for sure, just a guess. .  but yeah i was on 1909 too.  i thought the reason mine would never update to the 21h2 because i hadn't updated the bios in a while.  i was still on 1407 on an ASUS TUF X570-plus
