No Operating System Listed in MSConfig. Can't boot into Safe Mode

Disk 1 is where my Windows 7 is installed. Disk 0 is just a secondary drive. I only have one operating system installed (which is Windows 7). The system boot is the active partition in NTFS format.

Some OEM computers (HP, Dell, Sony etc) has some maintenance tools on the System partition. These tools (disk check, memory check etc) are accessed before loading windows. It is important to us to know your hardware.

I managed to execute all the commands up until bcdboot c:\windows
It gives me error:

"Failure when attempting to copy boot files"

I didn't reboot the PC yet, not sure if it will make my PC unbootable. Should I set the active partition back to the system reserved partition? (and if so how would i do it?)

Ok before rebooting, I used diskpart again to select the system reserved partition as the active partition (phew)

list disk
sel disk 1
list partition
sel partition 2
act
exi

Then I rebooted and I'm back.
Still No OS Listed under MSConfig and cant boot into safe mode, I think its just better off I do a reformat because this problem is hard to fix.
I have already tried the "startup repair" via booting from Windows Installation disk before, but it didn't work
nor did booting from Windows Installation USB disk as well.

I would have tried using the command prompt to repair bcd using bootrec, but seeing that bcdedit and bcdboot commands don't even work, I doubt it will work: How To Fix The Windows Bootloader - TweakHound

I have a question however - If I am to reinstall Windows 7 again, how should I reinstall Windows Updates?
Should i follow this article: How to Update Windows 7 All at Once with Microsoft’s Convenience Rollup

(Involves installing the Install the April 2015 “Servicing Stack” Update and then Download and Install the Windows 7 SP1 Convenience Rollup)

or I should just straight up download and install the Simplix UpdatePack 7? Download Simplix UpdatePack 7 - MajorGeeks

I am confused as to which Windows update should be installed in what order. Not sure if the April 2015 “Servicing Stack” Update and the Windows 7 SP1 Convenience Rollup is included in the Simplix UpdatePack 7

Oh and as for my Windows 7 PC, its custom built. But ill edit my profile later

Ok i will go for the simplix update package route, because it doesn't include Microsoft's Telemetry nonsense updates (I think the convenience rollup does?) Hopefully it also includes the patch for Wannacry ransomware too.

Thanks for the help. Anyhow for those who are curious how I got to this point, I needed to uninstall Avast Anti Virus, I used the
cleanup tool that Avast specifically provides in their website. It involves booting me into safe mode, which I successfully did and
it uninstalled without a hitch. After that, I thought something had went wrong when I couldn't run cmd as admin (but nothing was actually wrong), but it was to a point prior to Avast being Installed, so after the system restore avast was Installed again by itself.

I think it was either uninstalling Avast or System restore that did the damage to MSConfig not listing any OS and me not being able to boot in safe mode anymore. Either way, lesson learned. Avast has been getting pesky lately installing their Avast Safe Browser forcefully without user prompt or consent (It just installs itself magically like spyware). I'm looking forward to a reformat , trying another AV and I didn't bite more than what I can chew by trying to fix this any further. At the very least I was able to backup all my data. Just seeing that there's no OS listed in MSConfig and not being able to boot into safemode is a redflag to start backing up data. Although I have seen some able to fix this problem, its only on the presumption that the bcdedit and the bcdboot commands are working for them.
