Please help having trouble with windows 10 & 7

Question

So basically in my pc i had 1 disk of approximately 500gb, and i made a 10gb partition from this HDD for my lubuntu os, and i use it normally, but then when i travelled out of the city, and i came back 1month later, my linux distro (lubuntu os) is not working anymore it doesnt want to boot, so i decide to delete it from the partition from my main windows10 os, (i was dualbooting lubuntu and windows10), after doing that i was working normally in my win10, but after turning it off to go to sleep, then turning on my pc the next day, i get the filesystem "unknown entering to grub rescue" error

so i search up a tutorial, the tutorial tells me to type "ls", then try to find which drive from the ones that pop up is the one that has my windows 10 to you know, make it an active partition, cuz thats what i tought the error was, but that didnt work i get the filesystem unknown error in every one of them, so i try the second solution the tutorial gave me, and it is to burn a windows to a usb and boot from it then use the cmd from that windows in the usb to fix my hdd, so i try that, but after i select my pc to boot from the usb (which had windows 7) i get the loading screen 'windows is loading files', then it gives me this error:

Windows Boot Manager

Windows failed to start. A recent hardware or software change might be the cause. To fix the problem:

Insert your Windows installation disc and restart your computer.

Choose your language settings, and then click "Next."

Click "Repair your computer."

If you do not have this disc, contact your system administrator or computer manufacturer for assistance.

File: \windows\system32\drivers\ql2300.sys

Status: 0xc0000221

Info: Windows failed to load because a critical system driver is missing, or corrupt.

Answer 1

Hello

what is the exact machine model?

I tried to search "ql2300.sys". It seems to be the driver for "QLogic Fibre Channel Adapter" and it seems to be quite old.

Please try to boot into WinRE and choose "command prompt" mode then run the following command line to check the health of system files.

"SFC /Scannow /OffBootDir=C:\ /OffWinDir=C:\Windows".

Assume the "C" drive is the system drive. Replace the c with exact system drive.

If you are pluggin any external disk to the machine, unplug it.

If you are using IBM model machine, the following link may be useful.
