    Windows 10 Infinity reboot loop


    Hello,

    Today I was trying to do a hackintosh on another computer and was using my laptop to flash the usb for the hackintosh. One time usb stopped working, so I tried to delete an upper and a lower filter from regedit. Since that I couldn't boot up windows. I have tried to restore it using another same edition, same architecture Windows 10 edition from another computer (viewing which values I have missed) from recovery console but nothing. The computer starts, shows the boot logo for about 15-20 seconds, then reboot and run troubleshooter, troubleshooter doesn't find nothing and ask me to restart the computer. And the proccess repeats infinitely.

    Is there a way to fix this Windows without formatting?
    PD: It's an x64 Windows 10 Pro machine

    Thanks

    Assuming:
    1. Whatever you've done or tried to do (that's so non-specific I've no idea what it is) hasn't made it impossible to recover Windows
    2. The ONLY problem is that you've hacked the registry and thus somehow stopped your PC booting
    (and these are big assumptions)
    then
    Assuming you had turned system restore on and you have any useful system restore points
    then
    the first thing I'd try would be System Restore
    - which you can start by booting your PC from a Windows install disk, click 'Repair your computer' and navigate through the prompts to Troubleshooting and a System Restore prompt.

    Failing that you could try restoring the backup copy of the registry (you would need instructions- more technical)- no guarantees.

    You mention a troubleshooter- which would that be?

    Note: we constantly and strongly urge people to use disk imaging routinely - e.g. Macrium Reflect (free).
    If you had disk images, you could restore Windows from one without technical help.

    Win 10 doesn't have a Recovery Console as such- I assume you mean the Advanced Startup and Troubleshooting Options as here:

    I'm sorry, I haven' posted more info. The troubleshooter I mention is the one that says 'Diagnosis your PC' at boot and then opens the Advanced Startup Options. I don't know why but says that there isn't any restore point on the computer. I have tried advanced startup options -> boot repair, trying to boot into safe mode. If I boot into safe mode it does the same thing. If I disable automatic reboot on BSOD the computers stucks on boot. I have tried sfc scannow.

    If you can't boot properly and log in, to run SFC /Scannow without Windows running needs a special format of that command- to run it offline.

    As you indicate the problem is registry related, running SFC /scannow won't help you as that deals with system files.

    As you can't boot, you can't do an in place upgrade repair install.

    Your only hope, without system restore points and without having created disk images, seems to be to try restoring the registry backup; there's absolutely no guarantee this will fix your problem.

    If this doesn't help, you'll need to back up any data you need and then clean install.

    Ok, now start using disk imaging - starting right now.

    Here's my write-up on the value of disk imaging.

    Everyone who contributes regularly here uses and recommends disk imaging.

    If you use it, you can recover from:
    - a failed disk drive (restore to a new one)
    - ransomware (which encrypts your disk)
    - user error
    - unrecoverable problems from failed updates to problem programs
    - unbootable PC (hardware faults aside)

    Images also act as a full backup- you can extract files too.

    You can even use images to help you move more easily and quickly to a new PC.
    Can be used with Laplink software to transfer your build automatically to another PC

    Imaging can even help you sleep at night knowing you have a second chance.

    Creating disk images lets you restore Windows and all your imaged disks and partitions to a previous working state from compressed copies you have created and kept updated on external storage media, quickly and probably without technical help.

    Many here recommend Macrium Reflect (free) as a good robust solution and more reliable than some others. It’s
    - more feature rich
    - more flexible
    - more reliable
    than Windows Backup and Restore system images.

    It's well supported with videos, help and a responsive forum.

    There are other such programs, free/commercial, some with simpler interfaces, but Macrium R is one of the most robust and reliable.

    How long does it take?
    SSD+ USB3 - maybe 15 mins for the first system image, less thereafter
    HDD + USB2 - maybe 40-50 mins
    That’s with little personal data, few programs installed.
    - of course, depends how much you have on C:
    (You can and should image all your partitions and disks)

    Once you've created your first image, keep it updated with e.g. differential imaging- which images just changes from the first image, more quickly, and creates a smaller image file.

    You need a backup medium - say- twice as large as the total amount of data you are imaging to keep a reasonable number of differential images. This will vary dependent on the number of images you keep, so is only a rough practical guide.

    Some comment that system restore isn't always reliable; if it works and solves the problem, great. But sometimes restores won't work or fail. And of course a restore point only covers a limited number of aspects of the system. That’s where disk imaging comes in.

    (There's a tutorial on Macrium in the Tutorials section, and a couple of videos in the user videos section on this forum)
