Computer won't boot after momentary power outage

Thank you again for your help. I followed all of your instructions. I was able to see the additional options by pressing F10 and then chose F1 on the next screen to select "Launch Recovery Environment". After pressing F1, this is what I observed:

1. I got the Windows logo with a "Please wait" message for about 30 seconds.
2. The screen went blank for a few seconds.
3. A window that looked like the command prompt screen (but blank) appeared for a split second then immediately disappeared
4. It returned to the screen pictured below without ever giving me the option of verifying that the C: disk is the boot disk as you suggested.

In other words. it took me in a circle once again.

At this point, would using the command prompt be an option? (I verified that I am able to get to that under Advanced Options) I would need very detailed instructions on what to do there, but I feel like I'm running out of options.

Again, I really appreciate your help on this. Thank You!

Hi Kayakman19,

1. Since you can't even enter safe mode at the moment, we can't enter the login interface to log in as an administrator.
2. Regarding the queries of creating installation USB for another PC with Media Creation Tool, you can find the detail steps of fresh install below:

• Insert your USB drive into the computer that you want to make the USB drive on (your laptop as what you mentioned).
• Next, head over to Download Windows 10 (microsoft.com). In the “Create Windows 10 Installation Media” section, click the blue Download Tool Now button.

• After the software finishes downloading, go ahead and open it. The Applicable Notices and License Terms window will appear. Read and agree to the terms by clicking the Accept button in the bottom-right corner of the window.

• On the next screen, you’ll be asked what you want to do. Click the bubble next to Create installation media (USB flash drive, DVD, or ISO file) for another PC to select that option, and then click Next.

• Next, select the language, architecture, and edition that you want to use. Click the down arrow next to each option to expand the list of available options for that item. Click the option from the drop-down menu to select it. Click Nextto proceed.

• On the next screen, you must choose which media to use. Click the bubble next to USB Flash Drive to select it, and then click Next.

• After that, select which flash drive to use from the list under Removable Drives. Click Nextto proceed.

• The downloading process will begin. This will take a while.

• After the download is complete, click the Finish button, safely remove the USB drive from the computer, and then insert it into the computer that you want to install Windows 10 on.
• Once the USB drive with the installation files is inserted into the destination PC, you’ll need to set the boot order so that the computer loads the operating system from a different location—in this case, from the USB instead of from the hard drive. To do this, you need to access the boot menu on startup. When booting your computer, press the appropriate key to open the BIOS or UEFI controls. The key that you need to press depends on your computer, but it’s usually F11 or F12.
• Once you’ve selected the USB drive from the boot menu, your PC will reboot from the USB drive and ask you to press any key to begin the setup of the installation media.
• At the beginning of the setup process, you’ll need to choose the language to install, the time and currency format, and the keyboard or input method. In most cases, you won’t need to change anything here, but if you do, click the down arrow to display a list of options, and then click the option that you want to select it.
• Click Next to continue.

• On the next screen, click Install Now.

• You’ll briefly see a screen that lets you know that the setup is starting. After that, the Windows Setup window will appear. Here, enter the product key in the text box if you have one. If you don’t have a product key, then you can still run a limited version of Windows 10 that works.
• If you entered a product key, press Next. If not, click I don’t have a product key. (In this example, we’ll choose “I don’t have a product key.”)

• Next, you’ll need to select which Windows 10 version to use. If you have a Windows 10 key, be sure to select the correct Windows 10 version, as keys only work for certain versions. Click the version to select it, and then click Next.

• On the next screen, check the box next to I Accept the License Terms, and then click Next.

• The next screen asks you to select which type of installation you want to perform. Since we’re doing a fresh install, click Custom: Install Windows Only (Advanced).

• Next, choose where you want to install Windows 10. If you have a brand new hard drive, it might say Drive 0 Unallocated Space under Name. If you have multiple drives, select the drive that you want to install the OS on, and then click Next.

• Finally, the Wizard will begin installing the Windows files. The amount of time that the installation takes depends on the hardware you’re using.
• Once the Wizard finishes installing the files, your computer will reboot. In some unusual cases, you’ll get stuck in a boot loop where the system tries to bring you back to the installation process. This happens because the system might be trying to read from the USB drive instead of from the hard drive that you installed the OS on. If this happens, just remove the USB drive and restart the computer.

Hi Kayakman19,

Thanks for bringing your concern up here at Microsoft Community.

It sounds like your Computer won't boot after momentary power outage. Loss of power may result in damage to the system. It is recommended that:

1. Enter Windows Recovery Environment > Advanced Options > UEFI Firmware Settings to check if the startup disk is the system disk.
2. Enter Windows RE > Advanced Options > Automatic Repair to repair the system.

Feel free to post back if you need further assistance.

Lynn,

This is extremely disappointing news! Had I known that a complete loss of everything was going to be the result I would have never proceeded down that path unless absolutely all other alternatives had been exhausted. For example, I'm sure I could have removed the hard drive and had the data extracted from it directly. I was hoping that I would not have to resort to such drastic measures, but ironically, what I ended up doing (unknowingly) turned out to be far more drastic. For future reference, please consider full disclosure when offering this solution to anyone for a similar situation. People want to know that what their about to do is going to cause a complete loss of everything. I appreciate all of your help along the way, but quite frankly, this should have been handled much differently. Perhaps, the end result would have eventually been the same regardless of whatever other option there might have been, but I would have liked to know up front that what I was about to do would have these catastrophic results. Had I known, I would have at least had the opportunity to investigate other avenues or make the decision to proceed with full knowledge of the expected result. A very small percentage of data was backed up on my laptop, but what I lost can never possibly be replaced. I will be more diligent about future back-ups, but this didn't have to happen.

Hi Kayakman19,

Continued from above. If this is the interface you could see, click on Startup Settings.

Click Restart.

Press F10 to get more options.

 Press F1 to enter the UEFI setup interface and switch to Boot option to check the boot disk.

If the C: disk has been confirmed as the boot disk, then you can

1. Click the Startup Repair button.
2. Select your account > Type your account password > Click the Continue button.

Feel free to let me know if any update.
