Can´t boot, or enter safe mode, need urgent help
Al_Jourgensen:
Hello community
I´m facing a problem that i can´t solve. I have windows vista, upgraded to windows 10....
I had "Avira" installed on my Acer, but the constant publicity made me uninstall it with revo uninstaller, in the end, when i reboot, i couldn´t enter in my BIOS, safe mode, or windows.
After reading numerous forums, i can´t seem to find a solution, the only thing i could fix was entering in the BIOS again, by removing the "BIOS battery" and plug it in again. After this, windows shows up again the load screen, he also shows the log in screen, but after the login screen i only get a Black Screen where i can only see the mouse pointer.
I also notice that if i press Ctrl+Alt+Del, i can get into task manager, i can also bring up command prompt running it through the task manager, but my desktop is completely dark/gone......
I also try to run explorer.exe from the task manager but nothing happens, i checked if any other instance of explorer was runnig but no luck, there isn´t any......
I also did a command in my cmd, "taskkill /f /im explorer.exe" that i read in a forum to reset explorer.exe, but in the end it only shows up an Error saying he can´t connect to the server.......
I also tried Hiren´s boot cd, but with so many options i don´t know what to choose, i only did a check disk (no errors found), a memory test (no errors found), i also run malwarebytes, it found 2 malware files in system32, but after i reboot to clean them, i remove the usb that has Hirene boot cd, and nothing happen, i´m not sure if they were removed.....
I was wandering if there is a way to boot tweaking from an USB (like Hiren´s boot cd), and try to fix this mess.....
I thank you for your great job on this software, and for the possible answers to my case.
Thank you

There is a portable version of Windows Repair and while I've never used it, I believe you still need to use it from within Windows and isn't bootable.
Open the cmd.exe from Task Manager and enter rstrui.exe
This should open System Protection to see if you can use your restore points to before you uninstalled Avira, although I can't understand why uninstalling an AV program would cause you this problem.
If you are unable to use the restore points by this method then from the cmd prompt enter -
bcdedit /set {default} safeboot minimal
shutdown /r /t 00
and that should boot you up into Safe Mode where you should be able to use your restore points.
To revert from using Safe Mode, you can either use msconfig by typing that at Start then press enter and under the Boot tab, uncheck Safe Boot or from the cmd prompt enter - bcdedit /deletevalue {default} safeboot then enter the shutdown cmd again to reboot.

Hello my friend and thank you for your kind answer
I tried to restore it with a windows boot usb, following the normal procedure, but every restore point gives me an error, something like 0x00000*** and 0*** and it doesn´t restore
The cmd that i´m talking about is within windows after the login, where i can only run the task manager by pressing ctrl+alt+del, i don´t see star menus or anything else, everything is black
When i try to go into safe mode by pressing F8, nothing happens, and if i try to run it through the windows USB, i don´t even have that option to boot it in safe mode
i could try the cmd commands that you are advising me to, but i tried some and nothing happens or works.....i can only see the mouse pointer, nothing else, strange thing is the login, why does he login to a black screen....
this is unbelievable.....but i´m going to try those commands to try to run it in safe mode
i´ll feedback latter
Thank you for your attention

If that cmd gets you into Safe Mode and you get a screen, run MBAM again where it should tell you if you are now clean.
Depending upon what those infections were, they could have corrupted your restore points, but without a proper error code then it would be impossible for me to try and diagnose why they failed.
In Safe Mode you can go into msconfig and under the Boot tab, check the box for Network - Apply - OK and after the reboot, reinstall Avira.
You need to Ethernet connect to get Internet in Safe Mode in Win 10.
You can then revert to normal mode as I've described to see if it will boot normally.

I´m going to try it
as for the error code, i´m going to do the same procedure so i can tell you the error code.
I just want to try to get in a windows environment, from there i´ll fix anything, but it has been difficult....
Thank you again, i´ll feedback later
