Forced by circumstance I still had to use my barely patched up Windows over here, but I tried to keep it safe and scanned as often as I could. Except lately I did a ComboFix scan cause something didn't feel right, and by the time the scan finished, something happened (I don't know what cause I was away), but basically everything on the Desktop screen disappeared except My Computer and Recycle Bin, Start menu had everything gone except a few entries but their Icons displayed one of those slashed circles like it can't be found. Whenever I tried to open anything it gave one of those red error messages saying something like the specified path or task was deleted or moved, couldn't be tracked or anything. I reluctantly had to close the computer.
Since then Windows 7 doesn't boot and gives error 0xc000000f which I kinda looked into solutions. None of the boot options work, neither Debugging or Command Prompt now either as opposed to just the Safe Modes that didn't work before.
I put a Zorin Linux on a stick to try to get into there and browse and look for solutions but funny thing, my two drives were there, and the non-windows looked fine, with all files there and I could open them. But the Windows drive had like almost all files missing! No texts or pictures that I had a lot of, no nothing, just a few files that seemed somewhat virus protected by their Nature like Tor browser or the ComboFix folder. In Linux it still diplayed that drive as being 167 GB when C only has 151 maximum capacity, but none of the files are there.
I used a Hiren's Mini XP to look into maybe solving something, and it showed that C drive was 133 GB Free of 151, except all the files still visible in there are also just about 5 GB only with Windows being 4 GB of that. From what I looked into this it just sounds like its virus damage and my files are hopefully all still there. I tried some of the Partition and HDD Scan tools in Hiren's to see if they could do something but they just see that space as empty. I assume Mini XP is just as susceptible to whatever damage that was so none of the tools can read it right. Also mini XP tools often saw my Drive disk as just 1 320GB block as opposed to partitions, if that counts.
I didn't use much from Hiren's to be safe, but the one with more stability that I did use was a chkdsk on the Win 7 drive, and it found some errors but I only used it once. However after using this, Linux can no longer see the two partitions at all, neither Zorin nor Slax.
And it gets weirder. While trying to boot the comp, 1 USB port and maybe the CD-ROM doesn't read right or register, because I had a Linux on a DVD too and it didn't boot into it. But when I do manage to get into Linux, they seem to work fine. So BIOS doesn't see 1 pen drive for some reason too.
Also the stick I had with Zorin I assume got attacked and corrupted while I was browsing (hacker maybe?) because now it won't boot into it either but this other stick seems fine.
Before using Hiren's I also tried a System Repair Disk with automated repair only and it gave these values for Problem Signature:
01=6.1.7600.16385
02=same^
03=unknown
04=1046
05=External Media
06=1
07=Corrupt Registry –> I looked to get details and from all checks it did the registry was the problem, said Rollback Fail.
Locale ID=1033
I tried it again last night cause I heard it helps to do Automated Repair more times. It even gave 07=NoFoundCause and I think a different number in 04? And at times it said no error found. But Automated Repair spots Win 7 on drive D instead of C.
So yeah it seems my registry got deleted or something, and even some other stuff. The whole "can't spot C drive" and maybe the startup error is the same problem I think I had back in Autumn when someone helped me, because I remember he had to do stuff in cmnd prompt to get C seen, but that was also a blue screen related error too and at least the files in C were visible. And I wasn't really sure how to use the Hiren Registry editors on the Win 7 or what to do.
My tools for now are a multiboot drive with a Win 7 Repair Disk, a Hiren's Boot CD, Ultimate Boot CD and Slax Linux and I have another 16 GB stick with the corrupted Linux on which I may as well put something else.
I was also debating using this guide: https://neosmart.net/wiki/recovering-windows-bootloader/to fix the boot because it sounds good, but due to complications such as the invisible files I thought it best to wait and ask for advice.
Shall I do virus scans first? Is there some optimal way and order in which to use all these instruments? Command Prompt navigation? And so on. I don't have any system restore, registry backups or image disks, those all seemed deleted or invisible at least anyway. I also heard Easy Recovery Essentials was great for handling all this, but that one stopped being freeware it seems.
My goal for now is really just to get the old Windows back and booting again, or at least have my drives and files visible in Linux, because I need the computer to work, and I need to work to fix the computer for good, so it would be much appreciated bailing me out here again Q.Q.
