Repairing Windows 7 using USB drive

Solved

Hello!

After consulting several forums to help me repair my Windows 7 using a USB key, I am turning to the CCM community to find a solution.

After an automatic restart of my computer following updates, it simply refuses to load Windows.

I decided to run the Windows 7 repair tool by creating a bootable USB drive containing the ISO of the same version present on the computer.

The USB drive is correctly detected, and I am prompted to choose the language, region, etc... Then on the selection window (install or repair), during the repair attempt it seems that no operating system is found. Windows then starts a search for Windows installations that never ends - I let the search run for a full day without any result -.

Does anyone have any idea on how to proceed to repair Windows? I really do not want to lose the data on the computer.

Thank you in advance;

The likely cause of the failure to recover the Windows installation via the repair option is that the partition containing Windows is no longer recognized.
To check this, you need to enter command prompt mode and type:
1) diskpart
2) list vol
Please share the result to see if the Windows partition is recognized.

Hello Thev,

I don't have access to the startup options. Therefore, I can't use the command prompt. That's why I need to attempt a Windows repair.

I will try Lacharpente's method and update you on this.

Thank you!

I managed to access the command prompt via Hiren's and here is the list of volumes: https://www.cjoint.com/c/FAdql0LFWTS

The problem, in my opinion, comes from the partition of volume 2 (letter F) which certainly contains your Windows 7. The format of this partition is no longer recognized; it should be NTFS. It's possible that the partition table on your disk has been corrupted due to an incident during your last update.
A program that can fix this is Testdisk. Retrieve it, put it on a USB stick, and run it in command prompt via Hiren's.
You need to follow the displayed instructions. If you have any doubts, feel free to ask me because I have already used this program to recover a situation like yours.
