Windows 10: Windows 10 UEFI boot problem

Problem with windows 10 boot.
Hello, I have a huge problem with loading into my system...
Let me explain, what happened is that I installed dual boot Linux v.2020 with Grub dual boot, then I did something I should have not, to get rid of Linux that I didn't need anymore. I wiped the partition of the disk I was using to host it and repartitioned it back to normal, basically removing any trace of Linux, but unfortunately i ruined my system. When I rebooted I couldn't boot anymore, the grub loader gave my error and after a lot of research and trying to use a USB windows 10 installation to try to repair the boot through CMD I can't do anything yet. What I tried was to do diskpart, and try to bootrec /fixboot but it gives me errors such as "this is unavailable etc." Or "access denied", even if I tried to change the letter of the disk to V or C or anything at all still it gives me Access denied.

Now I didn't try yet to use an older version of the USB windows 10 installation because I have limited internet. I would like to know if there is any solution at all that doesn't involve reinstalling windows 10.

Specifics: Windows 10 professional x64

Disk win system is installed: 120gb ssd

Disk Linux was installed: same disk, 15 gb that were repartitioned from it.

I don't know what other information is essential.

Thank you for your availability.

Trouble installing windows 7 on RAID in UEFI

As the title says, I'm trying to install Windows on a RAID array in uefi on my Maximus V Formula. When using legacy ROM I can install just fine but I go into CSM and change settings to UEFI only, I can build the array in the UEFI Raid driver (IRST tab in "BIOS") but the array does not show up in the boot menu and when I try to install windows (boot from UEFI DVD drive), The drive does not show up in the Windows install. The next thing I tried was to enable UEFI and legacy oprom in CSM, boot from UEFI DVD drive and install to the RAID array (probably detected by legacy oprom) and it will install. After first reboot, Windows Boot manager will show up as an option in the BIOS boot menu so I set that as first boot device and reboot. I will get to the starting windows screen and then BSOD (too quick to get codes) The last thing I tried was Changing to legacy mode and installing windows to a different drive. once installed, I initialized the Raid array as GPT and rebooted, changed csm back to UEFI only but they RAID array still doesn't show in the boot device list so I repeated the earlier process hoping that It might work because I had initialized as GPT but it still BSODs on starting windows screen. Any help or suggestions would be greatly appreciated

I think you were on track with your first try. Windows installer probably needs the RAID driver in order to detect it on install.

 

Windows 10 upgrade problem, no input accepted

I really hate having to come here and ask for help, but I really am stumped. It hurts my geek pride. I have a PC with fairly modern hardware in it. It has a p8p67 pro in it. I have tried upgrading windows 10 on it twice now. Both times I have had the same result.

After windows finishes upgrading it goes to the log in/set up screen. I can't do anything. No keyboard or mouse input is accepted.

I will list some, or hopefully all, of the troubleshooting steps I have tried:

• Move keyboard and mouse to different USB ports.
• Try different keyboard or mouse.
• Restart computer, repeatedly.
• Google for related issues.
• Update Bios, because why not.
• Create boot media and revert to windows 7.

The windows 10 system restore boot media works fine with keyboard and mouse. All USB ports work in windows 7. I don't know what is wrong. I suspect that windows 10 is lacking a driver of some sort, but since the computer accepts no input I have no way of checking for which driver let alone installing it.

Please help me figure this out. If I have to revert back to windows 7 again, I am not going to get it upgraded to windows 10. Thank you in advanced.
