Windows 10 Minimum Storage requirement

[thatboioofy]

So I wanted to ask to see if this was possible. Basically i have a laptop with 32gb eemc storage and whenever i try installing windows it always says not enough storage. i was trying to use windows 10 x64 and it says on the microsoft website that it only requires 20gb. Is there a way to remove the storage limitation on win 10 or not

You can always compress the size of the windows by applying compact command both from cmd or during windows install in setupcomplete.cmd

@echo off
compact /compactos:always

thats the thing it wont even let me to the installation part as when i try to choose the 30 gb partition it just says that it doesnt have enough space to install windows

While you can use the CompactOS feature, it's a performance drag which doesn't help on a lower-end PC.
Unless you're installing an image older than W10 1903, the current requirement is 32 GB disk.

32gb eemc storage? oof . You dont even have 32gb, you have 29.xGB once it has been formatted and less after setup has created a boot partition so you might only have 28.5 to 29gb.
Setup is expecting pagefile and hibernation at least so if you disable both even without any removals it should allow you to install.

This is where "trimming the fat" comes in.(note to self - )
Remove uneeded languages(and support) and keyboards, fonts(i have a minimum font list for en-gb around here somewhere, adapt to your needs, note any Recommend and keep them too), 3rd party published drivers - thats drivers AMD sample.inf - not MS published driver for amd sample.inf - obviously keep anything required for the target machine. Look for the big components which i would say is anything over 100MB. A bunch of small components when combined can add up to a sizable saving.

When you have your image go back to setup and manually create a partition - lets say 16gb which will be 15.5gb after it nicks a bit for the boot partition, if setup says it cant install because its too small wipe and create a new partition of 17gb, basically everytime it fails increase size by 1GB till setup is happy.

You could start with something smaller like 10gb and increase by 500mb increments so you will get much closer to what your windows actually needs.

Try the BypassStorageCheck key and see if that works. If you can reach the desktop you will find that around 26 GB is used by Windows, but you can reclaim 15-20 GB by disabling ReservedStorage, Hibernation, and Pagefile. If you want a pagefile, manually set it to have the same min/max value, so that it never grows. The storage key can be found in forum searches, while the others are in NTLite and also have forum threads too.

Normally, I would just upload all the stuff someone needs, but in a scenario like this a user has to be decent at troubleshooting and Windows knowledge, otherwise the disk is just going to fill up quickly and everything will break, so it's not something I want to encourage by spoonfeeding. On that note, you also need to pause Windows Update forever, since it's going to constantly eat more disk space over time, and as you get closer to the limit of the disk the updates will fail, which is actually why ReservedStorage exists.

They can be manually recreated post install if they are required so disabling them to keep setup happy isnt a problem.

BypassStorageCheck is a myth, and only "exists" for W11 Setup.

The only way to skip the disk requirement is manually deploying the image using DISM /Apply-Image from WinPE. But then you're responsible for all the other tasks that WinPE handles.

Apply Windows Image using DISM Instead of Clean Install

and to see how easy it is

You get far more clicks with a misleading title like "Installing Windows the Arch Linux WinPE Way".

 

[Clanger]

Yes. But it is clear and easy to understand and 1080P and downloaded it is easy to view its full size and see exactly what he is typing and the fact he messes up on the way is exactly what many people would do and they will see exactly where they messed up.
I have already learnt something from it and that is how do dism apply an image instead of 7zipping-extract to.

Probably a better way to deploy windows 7 on newer hardware from a w10 or 8.1 iso than trying to get usb drivers(modded drivers) to work during setup.

Interesting. Is it still included with the TPM bypass in NTLite? My PC is offline at the moment, I can't check it myself.

 

[garlin]

Nope, I had nuhi remove it. You're down to BypassRAM and BypassTPM + SecureBoot.
