I right now have a 149 GB C:\ partition on my 2 TB SSD, but I wanted to create an exact sized 150 GB for C:\ along with the normal sizes for the other partitions that the Windows 11 installer creates during the installation. I know that I can just run a 3rd party partition manager to adjust the sizes of the partitions after the Windows installation but I prefer doing it during the Windows installation and then creating the remaining allocated space for my data which consist of games, user library folders, and drivers. I did find a website that tells you the size partition you need to set during the Windows 10 installation to get a specific size you want for the C:\ partition if including the other partitions that Windows 10 creates but nothing for Windows 11 (23H2). This is the site I'm referring to: https://windowspro.eu/windows-partition-calculator-install/ Here's how I want it set: 100MB ESP -> 16MB Reserved -> 150GB C: Windows -> 768MB Recovery -> 1.67 TB D: Data. I want it to display exactly 150GB for C:\ in "This PC" section in Windows 11. Is there any easy way to accomplish this other than through trial and error to get that exact 150GB for C:\ partition? When I mentioned GB and TB, I really mean GiB and TiB respectively.
