Solved Corrupted master file table & boot error--What should I do?

July 15, 2016 at 19:12:37
Specs: Windows 10
The short version: my Acer Aspire S3-391-6046 laptop crashed a week ago, and now it is unable to boot. It says the boot configuration data is missing or contains errors, with error code 0xc0000185. When I ran chkdsk in command prompt, it said the master file table is corrupted and Windows could not recover it. Diskpart also lists several volumes with Fs RAW (including C: ). I have tried startup repair and bootrec commands but it hasn’t worked. I don't really know what I'm doing/what to do, and would appreciate help from some informed people. Microsoft support suggested renaming & copying over registry files, but that was before I did chkdsk and I'm scared of doing something that would make my situation worse.

Thank you for any help you can give me!!!
More details:
At the time of the crash, my computer was on but not running anything at the time as I had been watching a DVD but ejected it because it started glitching. I got a blue screen that said, "Your PC ran into a problem and needs to restart. We're just collecting some error info, and then we'll restart for you. If you'd like to know more. you can search online later for this error: SYSTEM_SERVICE_EXCEPTION (dxgkrnl.sys)."

When the computer finally restarted, I got another blue screen that said,
Your PC/Device needs to be repaired
The Boot Configuration Data for your PC is missing or contains errors
Error code: 0xc0000185
You'll need to use recovery tools. If you don't have any installation media like a disc or USB devices, contact your PC administrator or PC/Device manufacturer."

I made an installation disc and did Startup Repair multiple times but each time it said Startup Repair couldn't repair my PC. So I also tried opening command prompt and running bootrec /fixmbr and bootrec /fixboot and bootrec /rebuildbcd. It said each operation was completed successfully and the total identified Windows installations was 0. Then I restarted the computer and got the same error message as before.

Later I ran chkdsk c: and it said
"The type of the file system is NTFS.
Volume label is ACER.
WARNING! /F parameter not specified.
Running CHKDSK in read-only mode.
Corrupt master file table. Windows will attempt to recover master file table from disk.
Windows cannot recover master file table. CHKDSK aborted.
Failed to transfer logged messages to the event log with status 50."

Also, when I did list vol in diskpart, it lists six volumes (besides the USB DVD/CD drive). There’s
Volume 1, Ltr: C, Label: [blank], Fs: RAW, Type: Partition, Size: 284 GB, Status: healthy, Info: [blank]
Volumes 2-4 and 6 have nothing for Ltr or Label and say Fs: RAW, Status: Healthy, Info: Hidden
Volume 5 has nothing for Ltr or Label and says Fs: NTFS, Status: Healthy, Info: Hidden
