Solved Windows 10 gets NTFS disk errors after booting from mod Windows7 Instl

[Objectful]

I don't know if this is for tenforums or sevenforums but I'm going to post it here nonetheless. I tried getting the Windows 7 installer to boot and it worked, using the Gigabyte USB tool. Unfortunately, the USB 3.0 drivers wouldn't work so I had to reboot into my default installation (Windows 10) and then I got stuck in a bootloop. I hard reset the computer and it did try to boot and it went into recovery, auto running chkdisk. After waiting, I managed to get to desktop and opened event viewer and found out that all of my disk drives had a corrupted NTFS filesystem. Here is a screenshot:
Most of the errors had this in the description:

Volume C: (\Device\HarddiskVolume3) needs to be taken offline to perform a Full Chkdsk.  Please run "CHKDSK /F" locally via the command line, or run "REPAIR-VOLUME <drive:>" locally or remotely via PowerShell.

And so on for the other disks.
I'm not going to try this again since I'm worried it's going to do even more damage than earlier. Does anyone have a WORKING, reliable tool / ready ISO for modern computers and does anyone know what may have caused this issue? Thanks in advance.

New hardware like yours need some drivers (USB3.x , SATA and NVMe) that are not on the Win 7 installation files. You need to add those drivers files to the Win 7 installation files.
SIW2 has made a script to add those drivers (USB3.x , SATA and NVMe) to the Win 7 installation files.
Update your Win 7 installation media

As things can go wrong, you should:
- Make a disk image of your current OS (Win 10)
- Install Win 7 on a separate drive (HDD or SSD).
- Detach all other drives (SATA or power cable) from the MB
- Once it's working without issues you can transfer it to your M.2 NVMe

I tried running the Windows install media on vmware and virtualbox and both hung on the Starting Windows screen. I've had this problem with other modified Windows 7 install media and the only one that didn't hang was the Gigabyte USB tool, which only added a bootx64.efi and that's it, even though it said it was installing updates and that.

The \efi\boot\bootx64.efi is only to be able to boot the installation drive as UEFI to install Win 7 64 as UEFI-GPT.

Once again, you need to add the drivers (USB3.x , SATA and NVMe) to the Win 7 installation files.

Ok, I managed to get a working ISO and got it to boot in Virtualbox (I don't know why it wouldn't boot in VMware) but I am still pretty scepitcal about running it on my main computer. By the way I have UEFI with CSM enabled and Secure boot disabled and both of my disk drives are formatted in GPT. Will Windows install in MBR or GPT when I'm running in UEFI CSM? Also do you know what made my computer bootloop and show NTFS errors? Thank you.

Depends how you boot the Win (7 or 10) installation drive.
Windows can be installed in two ways: Legacy-MBR or UEFI-GPT
To install as Legacy-MBR you must boot the installation drive as Legacy
To install as UEFI-GPT you must boot the installation drive as UEFI.

To install as UEFI-GPT, during POST, press F12(?) to launch the boot menu. You will see two options for the USB drive. USB UEFI (Name) and USB (Name). Select USB UEFI (Name).
Go to install and delete ALL partitions on the SSD till you have one and only one unallocated space and then proceed.
If you don't want to use MS account, don't enable updates or connect to the internet during installation.

Thank you. Unfortunately I have to buy a new HDD (I will not be installing on SSD) to test this out because both my SSD (Windows install and program files) and HDD (general files like downloads, etc.) are pretty important. Also I'm confused on why the installer corrupted ALL of my drives, not just the C:\ drive. By the way, I didn't get past the language select screen and didn't do anything that might edit the disk filesystem bitmap. Or it might just be a coincidence... I don't know. Anyways, thank you for your support. I will not mark this thread as solved until I get my hands on a new hard drive and get it fully working but I will thank you.

Buy small SSD to install only Win 7 and use the other drives for your data.

Ok! I just ran the new updated Windows 7 installer and it worked without screwing up the filesystem! I'm still typing this on Windows 10 but now I'm confident that installing Windows 7 won't do any harm.

EDIT: I guess the Gigabyte tool was to blame.
