Windows 10: Unmountable boot error loop

Hey everyone.

I am running Windows 10 on a Lenovo T520 computer.

My problems began when I was having issues with my computer being slow after the most recent Windows update. I decided to rollback my build. I did so, and then upon logging in, my taskbar would freeze and crash my entire computer.

Then, I fixed it somehow by working with the chkdsk feature. But, when it finally started to work again, my audio would be completely off, as well as my internet connection. I attempted to fix it, but to no avail.

Now, my computer is in a never-ending loop. I'll reboot my computer and it'll get to the loading screen only to tell me that there is an "Unmountable_Boot_Error". From there, it'll automatically restart and it just leads to a black screen. Mouse is responsive but nothing else. Just now, after a good 15-20 minutes of a black screen, it went to the normal boot screen that gives advanced options. It is running slowly, but so far I am cautiously optimistic.

I am on a spare computer running Windows 7 Pro. I was able to use the Windows Media Creation tool to create an ISO file on a DVD. However, I am unsure how to make it work.

Someone please let me know how to fix this! Thanks.

:)

Boot looping and Unmountable boot volume in Windows 10. Also getting the error "the require partition is missing"

Original title: Boot looping and Unmountable boot volume in Windows 10.

I just recently got boot looping error and blue screen stating that I got "Unmountable Boot Volume". I've tried suggestion by the IT support telling me to do the repairing system using the installation media. I've done that, and the same boot looping keep
happening while the system is in repairing. I've back up all my data in bios menu, but I can't access C: partition using Command Prompt in Advanced Option. After backing up the data, I tried to Re-Install Windows 10 by using "Reset PC" menu and delete all
data(since I've backed up all data), but it turn out I can't reset the PC since the error telling me that "...the require partition is missing", and I can't continue my re-installation, and I stuck in my boot looping laptop.

How to solve this?, Should I do a fresh install ? because the are 2 options in installation media, "Install Now" and "Repair this PC", I don't try this yet, and if I try I'm afraid I'll get the same result like "..require partition missing". My worst case
is that my C partition is broken so that I have to buy new internal hard disk, If I do this, can I install again the Windows 10 using the Installation media as a fresh installation?, without inserting product key, because I got Windows 10 by upgrading from
8.1. Thanks for your answer.
