At some point in our life, we face “no bootable device error” when trying to install fresh Windows operating system or an additional operating system. Unfortunately, many of us lack knowledge in the software area, which makes us believe that the problem is with the hardware or the device itself.
No Bootable Device Available – What does it mean?
No bootable device available means your PC/Lappy can’t find the hard drive. HDD is where your data is stored, this includes Windows or whatever operating system you have installed. Since your computer can’t find your hard drive, therefore it can’t boot or start Windows or other OS you using.
How to Fix No Bootable Device Error
There are many solutions out there regarding the issue but does all of it necessary to perform it? We have two answers “Yes” and “No.” Most of the solutions are in order simple to advanced, which is not the right thing to do because it consumes more time and you only get more confused.
We are going to show you the exact way, and the order will remain the same as well. There is no shortcut and if you want to get out of the situation sooner with lesser effort, then follow our lead.
When it comes to the error “no bootable device,” it is always a removable device, which caused the problem at first place. It happens due to lack of knowledge. If you are installing the operating system via USB device or USB DVD-player and you have “no bootable error” on your screen, then all you have to do is,
- First, check if there are any corrupted or missing files in the folder.
- Are you using a tool to make your removable device bootable? If not, then create a bootable Windows 7 USB device via Rufus.
- It happens to me a lot, have you configured correctly in the BIOS? (We will show you on the next stage.)
If nothing works, change the removable device and test with the spare one.
2. Restore the Operating System
In case, if you are using Windows 7 or 8.1, you can always restore your operating system to an earlier point. It’s not that Windows 10 doesn’t have this option, which we will discuss later. We understand that you are unable to login to your PC due to “no bootable device.”
Note: Recently, we have faced the same issue, and the cause of it was a removable device. If you have added a new hardware or USB device, then it occurs. Remove the device or hardware before you turn on your PC.
Here is the thing you have to do to restore to an earlier point.
Step 1: Now go to your storeroom and find the Windows 7,8, and 8.1 DVD or you can also use a bootable Windows 7 or your version of Windows USB device.
Step 2: Now go to your BIOS by pressing DEL button right after you start your PC
or you can directly boot using F12, F10 or ESC button. Remember, you can use any of following function keys, but it won’t work for all manufacturers.
Step 3: Above menu, select BOOT.
Step 4: For every motherboard, the option format is different, but the name and functions will remain the same.
Step 5: You have to set DVD-Player first, I’m repeating keep it again to set the DVD-player as the first boot. If you are using a USB device, then your primary hard drive should be on third.
- First – DVD player.
- Second – USB device.
- Third – Hard disk.
Step 6: Now save it.
Step 7: When the operating system loads, and you have the Install button on our screen, you can see that there is a repair option. It will show you few more options, and this is what you should seeing on your screen on both Windows 7 and 8.1.
- Startup repair.
- System Restore.
- System recovery image.
- Windows memory diagnostics.
- Command prompt.
Step 8: If there is a restore file available, it will show up on your screen.
Or Windows 10 of any build version. The method applies to all version Windows 10. For Windows 10, the format is slightly easier, so follow our lead.
Step 1: When you start your PC, keep clicking F8 (Function 8 ) button on your keyboard.
Step 2: Now select Troubleshoot.
Step 3: Click on Restore.
3. Using CMD Prompt
Here comes the complicated part of the whole procedure, which will drive you nuts without guidance. All you have to do is to follow our steps. It might look a little complicated, but when you make your first move, it will only make things easier for you.
Select Command Prompt from the system recovery options.
Step 1: Open the CMD Prompt.
Step 2: Type the below codes and enter, repeat the process till you have entered the all,
- bootrec /fixmbr
- bootrec /fixboot
- bootrec /scans
- bootrec /rebuildbcd
Note: We have not tested this method in the past but this a suitable option provided by the Microsoft.
The second method is a working method, which we have used it in the past.
Sometimes, your hard drive partitions are locked by the manufacturers or by a program which you have used earlier. You can unlock it and make it act as primary.
Step 1: Open CMD from the options.
Step 2: Now type “Dispart” and enter.
Step 3: Now type “List disk” and enter.
Step 4: You have to “Select disk 0.”
Step 5: Now you have to select the one which is a “System reserved partition,” the easiest way to identify it by the size. They are sized between 100MB to 500MB. The size of the partition is always lesser than other partitions.
When you have identified your partition, type “Select partition 1 or 2.”
4. Re-Install or Reset Windows
Those who are using Windows 10 are fortunate because it comes with an option called “Reset” which is a fantastic option. However, if you are a Windows Vista, Seven, Eight and updated version of eight, then you have to re-install the operating system.
You can find thousands of articles on how to reset and reinstall the Windows tutorials. We prefer you to watch this video created by Acer. In case, if the boot settings isn’t working out for you, then Google it because every manufacturer has different format or try these “F10, F12, F8, and ESC“.
Wrapping it Up!
We have tested these methods and experienced them personally, that is how we are able to suggest you these points. If the Windows PC gets stuck at some point, then wait for a while (10 minutes max) then restart it and repeat the process.
