Fix “Windows Could Not Be Installed to This Disk” Error:
Even if you rarely Reinstall windows These days, if you ever do this, there are some speed hurdles on the road to install windows. One such error is the “Windows cannot be installed on this disk” message, but we have some possible fixes to overcome this particular problem.
Additionally, you may see an additional line in the error message, specifically either “The selected disk is of the GPT partition style” or “The selected disk has an MBR partition table. On an EFI system, Windows only installed on the GPT disk May go”. We will explain in detail below what these messages mean.
UEFI, BIOS, MBT and GPT conflict
This error results from a conflict between the type of firmware used by your computer and the partition table standard with which the hard drive under consideration is formatted.
Older computer a. Let’s use BIOS (Basic Input Output System) Firmware type, which is compatible with the MBR (Master Boot Record) standard for managing partition tables.
Newer computers use the UEFI (Unified Extensible Firmware Interface) firmware type, which can work with both MBR and GPT (GUID partition table) drives. However, in the case of MBR drives used with UEFI, the partition must be smaller than 2TB in size. If possible, use GPT-formatted drives with computers of UEFI type.
For a more complete explanation of MBT and GPT formatting, see MBR vs GPT: Which format is better for SSD drives? However, now that you know this common cause of the error, let’s look at the options available to solve the problem.
Switch between UEFi and legacy BIOS mode
While most modern computers use the UEFI firmware type, many still offer “legacy BIOS” or “legacy boot” modes to resolve compatibility issues.
Your problem may actually be due to the wrong mode being turned on. If your drive is formatted using the more modern GPT standard and you boot in legacy boot mode, Windows will not work with that drive. That’s why you “The selected disk is of GPT partition style“It means you need to do either Convert disk to MBR format Or change the boot settings in your BIOS to UEFI.
If you are getting another message “The selected disk contains an MBR partition table”, You need to do the opposite. This means that you must either convert the drive to GPT format or boot your BIOS into legacy mode.
Legacy boot modes are not intended as a permanent solution, so if you need to use it to access the disk, it is best to backup data on the MBR partition that you want Windows to install and then have it in GPT Want to change.
How you turn legacy boot mode on or off depends on your specific computer. You need to access the firmware menu at boot time, which is usually a. Is done by pressing Specified key. Look for that information on your motherboard or in your computer’s manual.
Once in the UEFI menu, look for an option Enable legacy BIOS / boot mode And change it to the desired settings. Some computers also have a third mode that supports UEFI and Heritage. So if you see that then choose that option.
Reformat the drive with another partition style
Changing the GPT drive to MBR or vice versa will delete all data and partitions from that drive. However, if you want to run your computer in UEFI mode then you need a system drive that uses GPT. We recommend that everyone use UEFI if possible as it is more secure and has many advantages over MBR.
However, if you are getting this error, it is probably because your computer only supports the legacy BIOS and your drive is formatted with GPT. In this case, you can solve this problem by converting the drive to MBR. Go ahead and look How to convert a disk from GPT to MBR.
Again, this is only recommended for systems that do not have UEFI. On a UEFI system you should use the GPT format for your Windows disk.
Making a fresh start during Windows installation
Windows 10 is a robust disk management application built directly into installation software. During installation you will be given the option to remove all partitions on the disk and format it. Windows will format the drive using the correct settings it needs to work.
If you have data on a drive whose backup is not backed up elsewhere, this is a bad idea. If you are not concerned about the data on the current disk, this is by far the easiest way to solve the problem when installing Windows.
If you are not sure how to reinstall Windows, just read our in-depth guide which goes further Three ways to install windows. In the Windows installation process, when you say “Where do you want to install Windows?” Dialog, just follow the steps below.
- Select each partition in turn, then select Remove Unless a partition is left.
- Choose next And Windows will format the spaces correctly and create appropriate partitions.
From there the installation can proceed normally.
Using third-party software to change the partition style without formatting
There are third-party applications that offer the possibility to change your partition style without losing any data. This is possible, although what such applications actually do is erase and replace every bit of data on the disk as it reformat the media.
However, if the process is interrupted for any reason, you are likely to end up with a disk that needs to be reformatted in some way. It is always a good idea to backup your disk (or at least important data) before doing such a conversion.
Additionally, for obvious reasons you have to do this conversion when running the operating system from a disk other than the one you want to convert. This means a. Boot from Live boot disk Or using an external disk enclosure with a separate computer to complete the work.
Feel free to check our list Best free hard drive formatting and partitioning utilities for Windows. Some of these tools will allow you to convert your hard drive partition format without complete correction.
Overall, if you get this error message, it will complicate things a bit. Fixing this is not the easiest error, so take your time and post a comment if you have any questions. We are usually very good about getting back to people.
Hopefully you can follow this guide and install Windows on your disk without any problems. Remember, to be safe, back up your data before you do anything.
