Windows 10: installing windows after Inaccessible boot device

few days ago i tried making my DVDRW work through deleting upperfilter and lowerfilter in regedit. but instead i suppose i deleted my hdds Computer\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4d36e967-e325-11ce-bfc1-08002be10318} . and now i cant boot my pc with INACESSESIBLE BOOT DEVICE and error 0xc0000225. The thing is i had windows 10 installed on my HDD but i also have SSD in my pc with just some games installed. Can i somehow download windows 10 on my SSD with Windows 10 ISO on usb flash and access files on my hdd? i have important files there and i really dont wanna los

This is a Microsoft link on inaccessible boot device:
https://docs.microsoft.com/en-us/win...le-boot-device

It is an intermediate level link.
There are more advanced steps that can be ran once the partition structure is known.
There are steps for repair of the boot sector, operating system, etc.
Sometimes this bugcheck can be caused by windows updates.

A reset save files equivalent may be able to be performed.
Alternatively a clean install can be performed once important files are backed up.

I'm not sure if this is helpful, but maybe you can have a try. Windows operating system backups a working registry for recovery purpose. You can perform registry backup restoring to fix the inaccessible boot device error. The pre-condition is that you can access to the Advanced startup opotions of your PC. You'll need to use the command prompt.
Also, steps are a little bit complicated. However, if you follow the guide strictly, no mistake should be made. You can Google how to restore from Registry Backup, or refer to this article for help. Inaccessible Boot Device Lenovo.
