Windows 10: Boot problem Windows 10
Boot problem Windows 10
Hi, yesterday, in my PC with Windows 10 installed, I opened Windows 7 installer and pressed "Install now", I immediatly cancel the operation and a new partition next to C: showed up. I knew nothing about system partition, so I thought it was a new partition created and reserved by Windows 7 installation, so I proceded to delete the stuff inside (EFI and Boot folders). After that I restarted the computer.
Now without those folders I can't boot Windows 10, and it shows me the error: "Reboot and select proper boot device". I looked up for many tutorials but any of them worked.
I also tried to fix it by using Troubleshoot option with Windows 10 img started from a bootable USB but all the options fail.
I would like you to help me to delete all the partitions in my disk except the one container of Windows 10 SO (I can't lose those files inside, otherwise formatting would be an option), and then recreate the necessary partitions (System, etc.) and generate the necessary files to bring the OS back to life (hope it's possible).
Thanks for reading.
You may have deleted your main EFI folder, go into the BIOS/UEFI on your computer and turn off Secure Boot and if required turn Legacy Support on, then test to see if you can boot.
Then you could try doing a Windows Repair if you are able to get into it.
BCDBoot is a command-line tool used to configure the boot files on a PC or device to run the Windows operating system. You can use the tool in the following scenarios:
Repair the system partition. If the system partition has been corrupted, you can use BCDBoot to recreate the system partition files by using new copies of these files from the Windows partition.
<source> Required. Specifies the location of the Windows directory to use as the source for copying boot-environment files
The following example initializes the system partition by using BCD files from the C:\Windows folder:

I recently upgraded my windows 7 to 10. I had XP installed also. After the upgrade i couldn't boot from XP anymore(but it was showed on the boot list) so reinstalled it. Now windows 10 doesnt appear in my boot list so i cant boot from it...
After upgrading to Windows 10 from Windows 7 within the last week, everything was fine at first. Then this morning Everything on screen froze, and when I did a force restart, the following happened (and continues to happen ad nauseam):
Earlier this afternoon I decided to reset Windows 10 as I had a problem with BSOD BAD_POOL_CALLING over and over again. I booted in Safe Mode, went to Advanced Options and so on. It wasn't a factory-new reset, just the one that removes all files,...
Not sure where to put this, since it's not a BSOD, but it is very, very annoying.
I installed Windows 10 and began updating various things as one does with a new install. Drivers, apps etc,... at some point I began having a boot issue....
Ever since switching to Windows 10, I can not boot-up properly.
Whenever i have a cold boot-up, I will get the Windows 10 insignia with loading circle. Then, I will get a black screen, and my screen will completely turn off and not detect my...
