Solved How do i start in safe mode without boot disc?

Specs: Windows 8.1, Intel i3
How do I start windows 8.1 in safe mode? I can start my pc but after using sfc /scannow in cmd for whatever reason there is a corrupt system file that about 20 to 30 seconds after logging in the pc crashes and says it ran into a problem and needs to restart. Driver_irql_not_less_or_ equal (moulbamc.sys)

The thing is, it never restarts. It just freezes on the screen. Soooo i thought i could fix the problem of i could just get into safe mode and restore. Unfortunately i have tried all options i could find and nothing helps me either start in safe mode or access advanced startup. Here are some things I've tried:

Spam shift f8 on startup (maybe works eventually but after 5 restarts i gave up)

Shift + restart at log in screen (i read online that works but i never get a prompt it just restarts normally)

Went through entire regular startup menu

Since i have a little time when i log in i use Windows + x to access command prompt quickly then type "bcdedit /set {current} safeboot network" however the 4 successes i had typing it in led to a small wait that moulbamc.sys just won't let finish before crashing. This actually took a lot of practice i have to be real quick. (I tried going into pc settings but the second i go it crashes)

I went as far as taking out my ram sticks to flash.

Nothing will let me in safe mode. I'm confident once i get on i can fix the corrupt file so I'm not too worried about that... just getting to that point is my problem.

Any ideas?

Like i said windows 8.1 on an hp pc.

Fyi just to see i waited about an hour on the blue screen and it still hasn't restarted.

A lng shot...

Download and run kaspersky rscue disk. It's a linux based anti-virus item. It loads into RAM only and prseents a gui desktop. It goes online to update itself,and then scans the entire hard drive, and fixes (cleans out) whatever it finds. Then try booting into windows...

Why I suggest this possible fix? You mention you had a virus prior to present situation... It's remotely possible thst something akin to that is still affecting the system. Scanning from outside windows allows to find and deal with items that can be hidden within windows system files, and thus not detected nor removed... Booting as above means they can be...

Have you gone through all the options on this page:
https://www.howtogeek.com/107511/ho...

Shift + F8
If you can start msconfig and select "safe mode"

I can not find anything on moulbamc.sys. Did you install something prior to this problem? A game, GPU update or virus scanner, malware scanner...etc.?

Be aware that if you go with any form of factory reset/restore of the installation, then it's highly likely that your personal files will be lost... Similarly if you chance a repair installation (using a windows dvd) there is always the risk (albeit slightly less than with a factory reset/restore) of data loss.... So perhaps first download an ISO for a version of Linux, and burn to a DVD. Boot with that DVD. You can then access the hard drive and copy all important personal files etc. to external storage. DVD at least - and check the copes are OK; ideally to an external (usb connected) hard drive too. Check the copies are accessible on another working computer of course before proceeding with any version/form of factory reset/restore.

ubuntu.com is where to download ubuntu linux variant. and there are others variants too.

Several here use puppy linux - which is simpler (from what I understand) and easier to get across?

If you have another, working, computer, you can make a Win8.1 boot disk: https://www.microsoft.com/en-us/sof...

I literally said in the question without a boot disc. To those who suggested that...

I did get a virus prior to this btw and had used malwarebytes to remove it. Restarted np. Used sfc scannow. Restarted... now i get this driver not less or equal error.

To the person who said shift + f8 is it supposed to be spammed on startup? Or is there a certain time i can press the key combo? I'm going to try next accessing msconfig in the first few seconds of logging in but outs likely i won't have time to change options before blue screen.

Edit: msconfig won't even open before the crash

Any particular reason why you're asking how to drive a screw without a screwdriver?

Well, if you insist. If you're unwilling to use a boot disk, my suggestion is to rip out the system drive, mount it on a known good system, and do your work from there.
