Windows 10: Can't login to Windows after attempting to remove a virus

I'm using a Lenovo laptop with Windows 10 version 1903 32 bit
It was another normal day when I booted up my laptop when suddenly I got an alert from Windows Defender that my machine has been infected by the win32/grenam.b or d, I couldn’t remember exactly virus, which it identified as a spyware. I tried running Windows Defender quick scan, custom scan on a suspected folder, offline scan and even a full scan, but every time the scan is completed, Windows Defender would tell me that it couldn't completely resolved the issue.

I tried performing a scan using Malwarebytes but that didn't seem to do the job. I did give Microsoft Safety Scanner, a stand-alone antimalware software from Microsoft a shot but it didn't manage to detect anything

I got suggestion to run a Windows Defender scan within Safe Mode and booted into it using MSConfig.
And since I am using a Microsoft account, I learnt that I have to be online for my password to be accepted and so I switched to Safe Mode with networking and tried loging in with my Microsoft account password, and yeah, I mean, password, the correct one too, the one that I could one quentillion % guarantee to work to sign in to my account regularly, or on a different device, and no I don't enter pin because it clearly said password on the screen, but even with Safe Mode with networking I couldn't get a network connection and my laptop was showing me the Airplane Mode icon, which when clicked on, did nothing.
So without connection and can't get online, password will not work for sure, even if you have a correct one, I've even changed and reset it, yes, I did both, not because I forgot my PW, but purely because I wanted to test it out if that could help me boot my laptop into Safe Mode with networking but with all three passwords, the original one, the changed version and the one from the reset attempt, despite tested and proven to work when I used it on my phone, that didn't work, which I pretty much expected because I can't even get my laptop connected to the network, wirelessly I mean, not sure if using an ethernet cable with wired network is a mandatory but I didn't try that one
So after failing with changing password attempts, I tried to find if there's the option to boot back to my OS, but again, no luck, tried pressing enter in the boot menu displaying the boot options or locating the boot Windows normally option myself didn't work.
So I got myself a bootable USB flash drive loaded with the ISO file of my system's Windows 10 build, 1903 with 32 bit architecture and connected it to my laptop before powering it up with the Novo key next to the power button and chose the BIOS option and boot through USB before exit with changes saved
After the restart, I clicked on repair, then troubleshoot, and advance options, I think, and command prompt.

In the command line, I typed in the following command

c: bcdedit /deletevalue {default} safeboot and also

c: bcdedit /deletevalue safeboot

But both commands resulted in an error saying that system couldn't find the path or something like that

Actually, I forgot to mention that I'm blind and I'm a screen reader user, and when I said I did all those procedures, I was actually assisted by a sighted person since there's no sound on safe mode logon screen, to get Microsoft Narrator to work, I have to boot into Safe Mode, but I can't even boot my laptop, so that sucks, I wish Microsoft will consider enabling sound drivers from the logon screen so I could at least enable Narrator and have it read to me what's on screen in the login process without troubleing sighted people around me

Things get worse when my assistant tried to format my laptop without deleting any data but it kept asking for password that it have failed to except ever since I entered safe mode and I still tried putting the passwords but again, it says the password is incorrect with all 3 versions

I've been logged out of my machine since 23 October and it sucks so much that I couldn't use it what so ever

Is formating the laptop the only way left to return it to a useable state again? Or are there any other workarounds that I could try to get it working again? If possible, and if it's possible, I would like to have solution that could preserve my data on the machine.

Thanks in advance for your time and help, they‘re greatly appreciated.

Guide: Virus Removal 101

Software and Background​
In this section we will briefly go over the software being used and why we chose this software as opposed to other options. This is more of an academic type of post that will clarify the more important "WHY" when it comes to removal. It is important to understand that in order to effectively remove or have the best chance too remove a virus you must have the proper tools. The software listed below is based on several key points. Those mostly being.

• Free
• Easy to use
• Minimal user interaction
• Update friendly

At no point should you think that the software chosen was chosen because it is better than xyz or the "Best". That doesn't mean the software is "not the best" just that I am trying to break the mindset of "Best" it is important to shake the idea that a one off solution is always going to be the better one.

A Porsche is fast and will get you to work sooner than an 18 wheeler but if your hauling tractors to work the 18 wheeler is better suited. This is no different in the security world applications are built for a specific purpose for the most part and because of the nature of heuristic code engines some software will do better than others even if it is the same area of interest.

Software List​
- Threat Restraint

• Rkill

-Rootkit Removers

• TDSS
• bootkitremover
• MBAR

-Broad Spectrum Scanners

• Roguekiller
• EEK
• MBAM
• Sophos VRT
• HitmanPro

- Malware/Junkware Removers

• ADWCleaner
• JRT

-Targeted Repairs

• Powerliks
• Combofix

-Wrap-up and Repair

• TWEAK
• REVOuninstaller
• Ccleaner

Examples

Above is the list of software this guide will cover and what you will be using to disinfect the machine in question. Now; we will go more into why we separate them into groups in the next section. Here I will explain weakness and strength between software types and programs so you can understand why there are so many.

A common question is why don't we have a 1 all solution paid or otherwise that can handle all of well...all of this. The answer is simple.

You can't.

Every virus removal tool is different in some way. Some are able to detect things others can not. Above are the groups of different software. For example EEK is a broad spectrum scanner. However EEK cannot detect rootkits as well as programs specifically designed to remove rootkits like TDSS. Likewise Programs like TDSS are completely incapable of detecting malware, it simply isn't programmed for it.

Software in the same category also behaves differently. Hitman is very good at detecting browser issues and cookies. However Sophos isn't so great at browser infections but is better at scanning core system folders.

The AV world is full of these kinds of checks and balances which makes proper removal more of a skill than a click of a few buttons. Nothing is 100% and you must rely on the differences the tools have to increase your chances of success.

- Running scans in order

Running scans in the correct order might be something you are unfamiliar with. I will try to break down the basic concept as to why this is important to you. For the most part it boils down to permissions. Be it actual NTFS permissions or actual Privilege. Digging deeper you should ALWAYS attack an infection in this order.

• Threat restraint

Threat restraint is an important step because it will allow you the user to more easily work with your machine which is probably super slow because of infection. Using programs like killemall or Rkill stop known malware processes which free up memory and CPU making it a little easier and faster to deal with your machine.

• Root/Boot Kits

As previously covered Root and Bootkits are low level infections that grant admin (root) access to the machine. This software also for the most part changes permissions of core system files in order to more easily control your machine. It is very important to target and remove these infections first because the modifications they make can stop other higher level removal tools from working correctly.

• Virus Scans

Actual Virus removal comes next. Trojans, worms, spyware all virus class infections cause some kind of issues with system services, built in security protection and have the ability to prevent removal tools from opening. These kinds of infections need to be delt with second so that we can ease the restraints on the system so that our tools have the proper permissions and resources to run.

• Mal/Junkware scans

These are the last class of tools to run. These infections usually adhere to the user level of least privilege. They are really annoying and bothersome but are usually the most simple to remove. Unfortunately the tools that remove them require the use of system resources most of the time and assume they have everything they need to proceed. For this reason malware and junkware removal scans are done last because they totally rely on the previous steps being done and corrected to run correctly.

• Repair

Repair tools like tweak are used last. These programs reset windows to a default usable state. From folder options and icon size to default services and program startup. Most of the virus removal tools correct security related issues that the virus they are removing affected.

However sometimes more things have been touched and damaged and for these we use repair software last to correct the remaining issues after a full removal.
